Stove Designs

3 Hour TLUD

All,

Attached are some drawings of a stove I have been working on. I hope at least some of you will enjoy looking through it. My design concepts are a bit odd, but they work.

IFB stainless liner school rocket stove
IFB stainless liner school rocket stove skirt detail

On a recent trip to Haiti, I completed the first prototype of a new school rocket stove. This one has a 26 ga 330 stainless steel firebox liner, 2½" insulating firebrick walls, and galvanized steel outer shell. The skirt is 304 stainless inside, 1" ceramic fiber in the skirt floor and walls, and galvanized steel outer. The mouth and firebox are 6½" x 6½". The pot is 40 qts with the top diameter about 1/4" larger than the diameter near the bottom, and is imported. The locally available spherical bottom pots made skirt construction extremely difficult. We hope to someday produce this stove in quantity at a combined vocational school/stove factory.M2k Tekno

On my trip to Haiti in March 2016, I finished the ammo box stovetop oven. It is made with two ammo boxes, ceramic fiber board insulation, some stainless steel sheet, and various hardware. The oven chamber is 13" x 13" x 5". I plan to add split firebricks on the floor for use as a pizza oven. It fits on a household rocket stove but could be used over virtually any heat source.nike black leather school shoes clearance outlet

Easy Oven Retained Heat Cooker
Easy Oven Retained Heat Cooker w/ Rocketworks Stove

Jo Kennard in Australia has developed a retained heat cooker the Easy Oven, and has developed an excellent table of recommended cooking times and recipes to go with it.

Inspired by traditional Haybox cookers, and made from modern materials, the EasyOven saves between 86% - 90% of energy used while cooking meals, keeps food hot (or cold) for up to 3 hours. It was field tested during the Christchurch earthquakes and the Brisbane floods, and it is at home both in rural kitchens and in suburban potlucks.

sink charcoal stove
rebar inverted pyramid charcoal stove

The inverted pyramid rebar stove is ubiquitous in Haiti. Lots of radiation and convection away from the pot. No air control. Pot is often placed directly on the charcoal which quenches the charcoal and interferes with good radiative heat transfer.
I cut up a scrap stainless steel kitchen sink, built a sheet metal outer box, put in 1" of ceramic fiber board insulation, and added legs and pot supports. The inverted pyramid grate will have the legs shortened and be placed inside the "sink". A slide gate with sets of progressively smaller holes will be added to the "drain" for air control. nike

Demonstration
One of the ovens in use.

Eco-Kalan has adapted their Binkga Oven (named ofter the rice cakes that the ovens make) to use both locally available coconut charcoal and stick wood fuel.

The system uses the same oven bottom, and two different covers, one for wood and one for charcoal. Both ovens can bake high quality Bingka rice cakes, but with two different levels of particulate emissions. (Notice the soot on the wood fired oven). However, both ovens are cleaner than the hornohan stove that Eco-Kalan would like to replace.

The Bingka Oven works over a range of cooking temperatures (325 deg. F - 500 deg F) and has can cook both bingka and torta breads (with or without filling). Rebecca is anticipating that it will also work for a wide variety of other baked goods.

They have demonstrated the oven for local parents, teachers, government officials, and others. They have also reached out to people who work with remote communities that in the mountains. The first commercial production will target bakers who are preparing the bingka and torta on the more common and smokey hornohan stoves and anticipate the newer stove will give these bakers the ability to make high quality goods with lower costs and improved health.

Marc Ayats Plana has been working on TLUD stoves and improved low thermal mass ovens. This TLUD powered low thermal mass oven was inspired by the Anderson's Recho Rocket Oven, and uses a Champion style TLUD heating stove to power the low thermal mass earth oven.

For Marc's excellent writ-up download the pdf TLUD-OVEN Description
These are some quick notes:

He has made some changes to the TLUD style oven

  • Increased primary air draft, which can apport enough oxigen to burn the charcoal generated during the gasification process and continue giving heat to the oven. Now the primary air enters around the lower perimeter of the reactor, instead of having a single inlet tube like in the original model.
  • Increased the length of the riser, which also sustains the diffuser. This extra extension allows the complete combustion of gases gasification to completely remove the visible smoke in the oven.
  • TLUD Reactor. Diameter: 20cm. Total length: 30cm. Fuel Height: 20cm
  • TLUD Outskirt. Diameter: 22cm. Diameter central hole: 10cm. Total length: 25cm
  • TLUD Riser and diffuser. Diameter: 12 cm. Total length: 30cm. Diffuser: granite piece 2cm thick and 15cm diameter
  • Fuel load: 3.38Kg pellets

The Low Thermal Mass oven is based on the Haiti Rocket oven http://www.rechoroket.com
To see more pictures of the TLUD oven and the process of construction go to:
http://cuinessolars.jimdo.com/forns/

In the Oven Temperature graph, you can see the complete temperature profile. Marc did a side by side comparison of both a 20cm reactor TLUD and a smaller TLUD, with 12,5cm reactor.
"Note: the temperatures refers to the inside side of the wall oven, half way between the baking surface and the top hole. Note2: the temperatures were taken by a temperature datalogger and a type K probe."

Potential Energy http://www.potentialenergy.org/ stoves are the stoves original designed in the Berkley labs for Sudan (the Darfur region). They are an energy efficient stove designed with the cook's needs in mind.

They have recently added an orange 'cool mesh' to the outside of their metal stove to help protect the stove user (and their children) from burns. The second photo is of a stove field test, where ladies in Africa can see for themselves the advantages and disadvantages of several designs.

The Berkley stove is created out of metal and then shipped to local artisans who assemble the stove in the field. This video shows part of the process.

The stove was developed by Adrian Padt and Aidan Oosthuysen, and Richard Pocock, and uses a familiar Rocket design surrounded by a wire cage to improve the stove's stability and reduce burns. It's a smart looking stove, it saves women time and energy in gathering firewood, and it has lower emissions than the solutions it is typically replacing.

Lighting instructions:

The Rocket Works Stove, web site http://www.rocketworks.org/

  • The Rockt Works stove is a high efficiency wood burning stove, designed to accommodate multiple fuels when required.
  • It is smokeless after initial combustion, thereby reducing the likelihood of carbon monoxide poisoning and reducing the emission of black carbon particles.
  • The outer cage remains cool to touch even after hours of cooking, due to our innovative design.
  • It is made from high quality, heat resistant stainless steel allowing for years of regular use.
  • It can boil 5 liters of water in 15 minutes using as little as 250g of wood, which is significantly less than traditional cooking methods.
  • Its thermal efficiency is 45%, for the Large Pot High Power, performed by the SeTAR Thermal Efficiency Test.
  • Its emissions are the best in its class.

Basic Specification:

  • Mass: 2.95Kgs
  • Height: 270mm
  • Diameter : 240mm

Notes from Paul Anderson
Gustavo has presented a very nice video of the use of a tall TLUD gasifier under a DUAL purpose stove frame (frame = stove structure without the heat source) that first boiled 5 liters of water in 12 minutes, and then converted into a plancha stove with chimney, cooking papusas (related to tortillas). Total cooking time 1 hour 45 minutes on one batch of wood chips/chunks (5237 grams) that yielded 1300 g of char. 25% weight yield of char. Probably could have operated an additional 10 minutes with pyrolysis fire and a slightly lower percentage yield of char.

Note: That is approximately 4000 g of fuel of pyrolytic gases (including moisture content that was probably near 15%). Any ash content (probably 1% of the raw fuel) remained in the char.

We are trying to (a) reduce the amount of emmisisons from charcoal production and (b) Condense and recover as much of the smoke into a usable product for your home/farm. Wood tar - the following is an explanation from the good folks at Food and Agriculture Organization of the United Nations (FAO) about what is going on in this process.
"The non-water component consists of wood tars, both water soluble and insoluble, acetic acid, methanol, acetone and other complex chemicals in small amounts. If left to stand, the proligneous acid separates into two layers comprising the water insoluble tar and a watery layer containing the remaining chemicals. Recovery of the water insoluble tar, often called wood or Stockholm tar, is simple - it is merely decanted from the water phase. This wood tar has uses as a veterinary antiseptic, a preservative for wood, a caulking agent, and as a substitute for road tar" http://www.fao.org/docrep/x5328e/x5328e0d.htm

 Quad – 2012 to Present
Quad Flat Assembly

The Quad TLUD has features for easier production (using tabs and slots, and zero rivets), easier shipping (as flat-pack pieces), local assembly, and greater stability and coolness of four wooden handles that serve also as legs. Without question, there will be further improvements as the number of users increases and they provide feedback. For example, households using the Quad TLUD stoves in various refugee camps could make suggestions that outsiders might fail to foresee. Jigs, tools and methods for making flat-pack pieces are being prepared in the USA for availability to stove projects worldwide.

Material: Sheet metal and 4 wooden handles/legs

Cost: Mwoto and Quad TLUDs sell for approximately US$15 in Uganda, and should eventually cost less, especially if purchased in bulk as flat-pack pieces to be assembled by a local project.

Dimensions: Currently one size, but size can be easily changed: Height: 19” (48 cm), Square footprint 12 x 12” (300 x 300 mm); Fuel cylinder height 14 “ (36 cm) with diameters from 5 to 7” (12 to 18 cm).
Test results of Quad and closely related TLUD stoves such as Mwoto and Champion:

CO & PM Emissions: Consistently the lowest for any of the natural draft stoves that burn solid biomass.

Thermal efficiency: Range from 35% to 41% currently. Expected to go even higher.

Fuel consumption: 1050 to 1600 grams for a standard WBT of cold start plus simmer (respectably low).

Fuel types: TLUDs can utilize a wide variety of low-value chunky dry biomass fuels (e.g. corncobs, tree seed pods, nut shells), including briquette pieces that can be locally produced from unused biomass. “Stick-wood” is not a common TLUD fuel, but can be used vertically as “wood segments.” Vertical segments also with papyrus reeds, bamboo, etc.
Options: The Quad can be made as a TChar variation for ease of using the created charcoal as fuel in a charcoal stove or as biochar that is added to the soil.

1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

3. The Innovations as of July 2013

I recently discovered these aluminum cookpots with stubby rods welded to the bottom to act as fins. These should improve heat transfer to the cookpot.

Unprocessed coconut hulls make lousy fuel.
Coconut hull fiber are generally know as coir.

It is a big business in India.
http://msme.gov.in/Chapter%206-Eng_200708.pdf
The fibers are processed into mats, carpet backing, potting material, and geotextiles (for erosion control).
On a small scale, the hulls can be soaked in water for at least a month and beaten to break the pith and used as mulch.
The pith leftover from fiber production is known as cocopeat.

X = your altitude in meters.
Y = the local boiling point (at standard air pressure)

If you know your altitude, it will give you the ‘standard’ boiling temperature.
If you know the local boiling point, you can work backwards to get the altitude where you are standing.

A loaded kinyanjui type barrel kiln carbonizing maize cobs
free fuel!
a full kin of maize cob and branch charcoal made in less the a day
the maize cob charcoal cooks with high heat and little smoke.

Four very good reasons why to make your own charcoal from dry maize cobs.

  1. They are FREE!! (minimal processing required and are widely available as a farm waste product)
  2. Maize cob charcoal is very easy to make and leaves few charcoal fines. (no need for expensive briquetting)
  3. They are easy to light and burn very hot with little ash and are perfect for cooking a quick meal.
  4. Using maize cob charcoal means ZERO reliance on tree's and forests, LPG gas or unreliable and expensive electricity supplies for your cooking fuel needs. And with a Cookswell Jiko you can bake, boil, roast and toast all of your favorite foods

And they have a nice collection of YouTube videos:

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.

The latest one

New video and print resources available at www.aqsolutions.org.

Contamination of drinking water sources by synthetic organic compounds (SOCs – e.g. pesticides, pharmaceuticals, fuel compounds, etc.) is a growing worldwide problem. Many of these chemicals bio-accumulate in the human body and cause cancer, birth defects and diseases of the reproductive system, and disrupt endocrine and neurological systems. However, few low-cost, sustainable and appropriate treatment technologies are available to rural and developing communities for SOC removal.

Water filtration using charcoal is an ancient practice that continues today in non-industrialized regions around the world, though it has not yet been rigorously demonstrated for removal of modern industrial pollutants. Unfortunately, charcoal production by traditional kiln systems is often a resource-intensive and highly polluting process, and kiln processes are typically not optimized for production of good water filter char. Low cost, energy efficient, environmentally sustainable and scalable local production of optimal water filter char can be accomplished with biomass gasification (e.g. cookstoves and larger units using the TLUD design).

The video and print resources available on the Aqueous Solutions website (www.aqsolutions.org) are intended to

  1. summarize current results of collaborative field and laboratory research pertaining to the use of traditional kiln charcoals and gasifier chars in decentralized water treatment that targets SOCs,
  2. provide instructional materials for construction and operation of small- and intermediate- scale gasifier char production units using local materials, and
  3. provide instructional materials for integration of biochar filtration into a multi-barrier small- and intermediate- scale water treatment systems constructed from inexpensive and widely available materials.
