Stoves-Cookers

The Stoves Discussion list has been sharing information to improve cooking stoves since 1996. We use this site, to keep track of the many types of stoves, their designs, and the progress that has been made to improve them, and spread efficient cooking stoves in world wide.

Use the stoves menu to narrow the list of stories to the type of stove you are interested in.

  • GEO fuel briquettes

    is a very low cost technology, and also for making briquettes with very less effort. This is screw based system, requires very less energy and space to operate. Briquettes can be made using human power, convenient for young or old in making briquettes from various types of waste material. Small pieces of waste papers, sawdust, leaves, wood shavings, rice husk, etc. can be used as raw material. Any sticky material available in abundant can also be added if required for producing compact and strong briquettes. The cost of each such device made up of iron is less than $8 (USD) or Rs. 400. Various types of stoves are available for using the briquettes, including some of these AVAN and MAGH series stoves can be used. Magh-1 stove with little adoption can also be used for briquettes as fuel. We can also make and use special stoves for the briquettes as fuel.

  • Dear friends,  

    www.rocketstove.org  is finally online! And our friend John page from Aprovecho has agreed, at least in the short term, to be the new web administrator.   

    Our goal is to make this a practical site. For example the key content that I have right now is the Institutional Rocket stove  design tool that will allow users to  generate a custom set of institutional stove plans (brick and metal)  just by inputting pot size and a few other  key inputs .Ideally this would be the site that users would  turn to for specific plans on how to construct  rocket stoves , bread ovens, dryers kilns etc. If you have content that features step by step stove plans please register and then post them to the site.  (note e: g it might take a day or 2  to approve your registration  as I have to manually  accept each registration ) .  Registered users will eventually be able to  produce their own home page if desired , or just add contact info. Foremost I would appreciate it if we could link your webpage to ours and vice versa.

    The second goal of the site is to link people in the stove community by interest and region . For example someone could turn to the site and be linked to stove producers, purchasers and/or researchers in  China, Guatemala,  or Uganda. As the site grows into phase two we will add more functionality (ordering stoves online, visitors donating to specific projects, etc)   but initially I would love to collect as many links and content as possible in the next few weeks for the launching of the site . 

    At present this is a volunteer effort , and John and I would appreciate any form of support (financial or otherwise) from the stove community to get this web page up and running. The webpage was only made public last week so we are still very much in our infancy so we appreciate your patience as we smooth out the wrinkles. 

    Also, Please feel free to forward this e-mail to anyone you think might be interested. 

    Peace

  • CONE SHAPED STOVE Khalid ELYOUNSSI, Centre National de la Recherche Forestiere, March 27, 2009

    Cone Shaped StoveCone Shaped Stove

    This improved cookstove has been developed in the CRF (Centre de Recherche Forestière, Morocco) to respond to a need of fuelwood saving cookstoves in rural areas. The idea behind its conception is to approach the combustion principle in a gas stove. This has been made possible by a cone-shaped combustion chamber. Cookstoves with such conception has not been tested before. See report attached.

  • Paul Anderson, March, 2009 How many of each major type of cookstoves exist in the developing societies(functioning in 2009)? The attached "draft" Matrix gives you my guesses. Perhaps YOU have additional input. Maybe we should change the Matrix. More columns, more lines. Or do you agree with what content? What I am attempting is to get us all reasonably "on the same page", literally on the same single page. Please look carefully at the two Notes at the bottom. In the general rank ordering, any stove type (or specific stoves within a type) might be shifted one or two columns to the left or right. But the question is, are the notes and orderings reasonably correct? There is no right or wrong, best or worst. By sheer numbers of units, the 3-stove fire is "best." It literally is "the competition to beat" for all of the other stoves. The file is an active MS Word document ( .doc), so you can change it as you please, but please indicate that you have altered it. (I desire neither the glory nor the blame for what you contribute.) It is a very small file and might be distributed with this message.

    Firing Things UpFiring Things Up

    See slide show attached. I did this in conjunction with a Woman's Club, "Kare in Okrane." Essentially, "Women of the Break of Dawn," a reference to women getting up a the break of day to prepare for the family's day. We did have hundreds of observers and a strongly expressed interest. In this case the rocket stove had the clear edge. Burning fuel is what people understand. Women have been doing it at their grandmother's knee since childhood. The Solar oven probably came in second. Here it was much like a microwave. I had to constantly open it up and invite people to touch the pot. Ouch, that it hot, hey it does work. What can you cook in it? Sadly the TLUD was more of curiosity. . The kerosene/propane like flame did surprise people, and I repeatly brought up charcoal and terrapreta as a benefit over time. However, the small size and short burn worked against it. I simply switch between two to resolve this. Best Regards to all Michael Trevor mtrevor@ntamar.net

    BP has taken a life-cycle approach, starting with the consumer need, through to regulatory and HSE assessment in the case of BP Arivi. BP Arivi is a low-sulphur paraffin fuel for domestic cooking, providing consumers with access to an affordable, high-value fuel, in safe and child-resistant packaging. Different options were considered to determine the most appropriate fuel to meet the needs of consumers and scrutiny of the supply chain was undertaken to identify key risks We are now commercially piloting this solution in the market in South Africa and there will be further iterations around the process.

  • Hello stoves community,

    At ETHOS 2009 we held a panel on stove safety, bringing in viewpoints from corporate standards development, national standards certification, and small to medium scale developers. The team led by Nathan Johnson (Iowa State University) included Crispin Pemberton-Pigott (New Dawn Engineering), Casper Thijssen (Philips), and Karabi Dutta.

    The panel gave a comparative analysis of how different stove industries (multinational corporations, medium-scale companies, NGOs, small developers, etc.) addressed fundamental stove safety questions. These topics included:

    a) applicability of standards and regulation;
    b) incentives and benefits
    c) facilities and equipment availability
    d) cost vs. benefit
    e) resulting action

    We determined that each type of industry has a different perspective that influences their path or actions towards a safer stove. And that all sub-industries may not produce safer stoves given the same incentive mechanisms or policies. As such more than one path to safety may be needed to reach the greatest amount of end-users (and producers). The panel ended the discussion with an overview present work in stove safety with recommendations for next steps.

    Please view the attached file for more details. I will be leading a group in 2009 to work on the following: assemble database of injury data, b) analyze incentive mechanisms, cost/ benefit, c) development of lab testing procedures for different stove categories, d) publication of findings/ results, and e) look for partnerships with international agencies to support safer stove design and production.

    Please contact me if you have any questions. There will be more updates to follow. Best,

  • CO and PM Emissions from TLUD Cookstoves Presentation to 2009 ETHOS Conference, Kirkland, WA 23-25 January 2009 Paul Anderson, Biomass Energy Foundation, January 22, 2009

    CO and PM in TLUDCO and PM in TLUD

    Introduction Since 2005, high quality quantitative data on emissions from cookstoves have been accumulating. For data to be properly comparative, both a standardized cooking task and reliable emissions measurements are required. The principal test continues to be the standard five-liter Water Boiling Test (WBT), about which much has been written and debated. Equipment for reliable emissions measurements has been gathered, installed, tested, and accepted for operation at the Aprovecho Research Center (ARC) in Cottage Grove, Oregon, USA. No known equivalent site exists anywhere else in the world. Sincere thanks are given to the Shell Foundation, other financial donors, the ARC organization, and the numerous scientists who assisted in the establishment and operation of those emissions hoods. While the ARC facilitated the gathering of data presented here, the author is responsible for interpretations and any errors or omissions. Dozens of different stoves have been tested to various degrees with the ARC equipment and methodologies. Hundreds of separate test results have been collected. The two measured emissions are carbon monoxide (CO) and particulate matter (PM). This report is focused upon those emissions from four categories of cookstoves: 1. The traditional “three-stone fire,” which provides baseline data. 2. “Simple improved cookstoves” that utilize basic combustion that is confined in various stove structures made of ceramics, mud, or metal. 3. “Rocket stoves” that utilize clear principles and designs that provide significant control over the amount of wood in the area of combustion, with some restriction on the flow of air to the combustion area. 4. “TLUD (top-lit updraft) gasifier stoves” that essentially separate in time and location three processes of biomass burning (pyrolysis, char-gasification, and combustion). They also emphasize separate control of primary and secondary air supplies. Robert Flanagan, a TLUD stove developer in China, has coined the term “third-generation cookstoves” for these stoves that have the capability to easily create and save charcoal for use as a “biochar” additive to improve soil fertility (as in “terra preta”) and to remove permanently carbon from the atmosphere.

  • This is an experiment using biomass in the KEROSENE WICK STOVE. http://e-kerbiostoveexp.blogspot.com/ (for more photographs) The stove was lit at the top using a little amount of biomass soaked in kerosene. The fine holes of 1 to 2 mm located all along the inner and outer frame are useful in achieving very good bluish flames. The flames continued for 30 to 45 minutes duration. Only at the end the performance was bad, the option was that, a lid was used to shut down safely. The fire was very high (Reasons I am not sure). If one does not have enough kerosene, and in emergency one can use the kerosene stoves too with fine wood shavings as fuel. The end product is very good biochar. I am thankful to TOM REED for explaining the functioning of a Kerosene stove, which was the motivation for doing this experiment. http://listserv.repp.org/pipermail/stoves_listserv.repp.org/2009-January...

  • Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Darfur
    Academy for Educational Development for USAID, December 2008

    1. INTRODUCTION: EVALUATION OBJECTIVES
    Around the world, conflict and natural disasters have displaced millions of people. Displaced populations fleeing to settlement camps and seeking safety in host villages often put great stress on natural resources, leading to environmental degradation and conflict with local populations. One of the greatest needs of people affected by crisis, be they displaced, settled, or on the move, is firewood or some other type of fuel to cook their food, heat their homes, and treat water for drinking and food preparation. The risks endured (especially by women and children) collecting scarce wood resources constitute some of the most challenging and serious protection concerns both in IDP camps and in villages where conflict over resources is high.

    Prepping Flower Shoots Covers UtakPrepping Flower Shoot Covers Utak

    It was asked if the ARC's stoves here in the Marshall make charcoal Absolutely

    I went back and looked after we had to use the stove because the propane ran out, here in town. you answer pulpy punky material or not yes the stove does produce charcoal.

    The charcoal in the pictures is charred copra used to light the stove and the pieces of the flower shoot that even show the grain and structure of the original pieces.

    The flower shoot cover Spathe or Utak is an often used fuel anyway. Ripped by hand into small strips it works particularly well in the ARC rocket stoves. Copra, dried coconut meat, is the major cash crop and source of income for most. Its use would be limited to only a few chips as a starter material.

    I find a spritz of kerosene from a old 409 bottle or even a squirt of WD-40 does fine as a starter too. Various pieces of fronds and leaflets are really bio trash stuff and if they can be use effectively a really handy application.

    As for char structure, after it goes through my blender I am not at all sure there is much left.
    Remember I have been using Charcoal slurppees for a while. Charcoal, fish scraps if there are and a touch of 20/20/20 and a pinch of sugar.

    So better cooking and may your terra preta plot grow too.

    Remember in the rocket stove I am use very "pulpy" stuff.
    In the TLUDS-- XL Woodgas and my tincanium ones--- they make charcoal. As for shell I have not tried it much yet in the TLUDS althought my son burned out the first XLWoodgas unit on it.

    I think a mix of broken shell chips with the chopped frond piece may work very well.
    The chopped frond pieces work well but the burn is rather short.

    In industrial applications like a bakery I am sure shell would be fantastic if you could get enough.I think everyone else would get it first

  • ARISTO. The Plant oil stove
    Yun Ho Chae, Grupo Ari SA, Santo Domingo, Dominican Republic December 3, 2008

    Two Burner ARISTO StoveTwo Burner ARISTO Stove

    With the purpose of developing a stove that uses a different fuel to petroleum and other conventional, 4 years ago was initiated the development of an alcohol stove, which presented several problems in its efficiency such as:

    A. Under performance in the generation of heat energy
    B. High cost of fuel (alcohol)
    C. High levels of evaporation of alcohol, which generated a minor use
    D. Smell of alcohol due to its evaporation
    E. Danger in use because of the high level of inflamability of alcohol in their natural state

    With these results has been decided to seek other fuel that could solve these problems.
    During 4 years we have researched and developed a stove that is capable of generate the same or better performance that gas stoves have and could solve the drawback of accessibility to gas in rural areas and areas far from cities.
    To that end we developed a stove that works with vegetable oil, whose characteristics are presented below.

    3. Description

    Aristo is a 2 stove burners that operates using all kinds of vegetable oil.
    The most known types of oils are Higuereta, jatropha, Camelina, African palm.
    They can also be used cooking oils made of soybean, maize, sunflower, although these are not desirable because of its high cost and are also products consumed at home.
    Another excellent option is the use of used cooking oil, which has a high performance at low cost.
    The stove oil has a good performance on fuel consumption.
    Compared with the gas generates a decrease of 40% in costs

    Features and Benefits

    1. Easy to use and fast ignition
    2. High level of heat energy
    3. Danger void, because the oil only lights inside the stove
    4. Do not emit toxic gases.
    5. The oil is not volatile, so you do not need special packaging
    6. No need of heavy and expensive storage tanks
    7. The oil can be obtained at any point of sale, in small packages
    8. In the fields can be sown to extract oil for own use
    9. It reduces the import of liquefied gas which would generate large benefits to the country.
    10. They can be used as heaters in cold regions.
    11. This produces a savings of up to 70% in costs compared with gas.
    12. It helps preserve the environment by reducing the felling of trees used as firewood for cooking.
    13. The oil stove is much more economical than a gas stove.

    Fuel source for small-scale industry heating application is becoming expensive. This is more so for food, grain, and other processing industries in Indonesia where the energy sources for various processes are highly dependent on conventional fuel. At present, the cost of LPG went up to IDR 7,000 per kg while kerosene and diesel to as high as IDR 12,000 and IDR 5,500 per liter, respectively.

    Stove DiagramStove Diagram

    This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

    But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

    Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.

    We have recently learned that BP is manufacturing a VERY similar stove

    If you cover the combustion air holes with aluminum flashing or sheet
