Aprovecho / ETHOS Stove Camp 2007- Creswell, Oregon
Jeremy Roth, Aprovecho Research Center, April 26, 2007

Once again, the annual Aprovecho Stove Camp will be held July 16-20 at the Aprovecho Research Center lab in Creswell, Oregon. Click here for a map

More information on the Aprovecho Stove Camp can be found on their website.
www.aprovecho.org/stovecamp07.htm

The Aprovecho Stove Camp is a chance for people interested and involved in the research, design, construction, and dissemination of biomass cooking stoves to come together for a hands on collaborative event. Participants will discuss, design, build, and test cook stoves in Aprovecho's laboratory. Sessions for newcomers and stove veterans will run concurrently.

Nordica MacCarty will do a training on how to use the Portable Emissions Monitoring System (PEMS) at Stove Camp July 16-20. We can evaluate emissions using the PEMS.

Paul Anderson will teach a session on TLUD (Top Lit Updraft) stoves.

We are awarding a $250 prize to the best natural draft stove...and doing a very thorough two day review called" Almost Everything About Stoves" that will run concurrently as folks build and test best stoves. (Two tracks happening at the same time). Tami Bond will probably be there and Dale Andreatta along with many other notables. Aprovecho has THREE COOL NEW STOVES to share.

COME ONE, COME ALL! Directions, etc. to follow!! Sailing on the lake, too!

Laboratory Testing of Rocket Stoves of Various Capacities As Compared to the Three Stone Fire
Dean Still, Nordica MacCarty, Aprovecho Research Center, April 2007

In an effort to understand the relationship between stove capacity and fuel use and emissions the performance of three sizes of rocket stoves were compared.

[img_assist|nid=1582|title=|desc=|link=node|align=center|width=758|height=450]

The stoves were tested with the 2003 UCB revised Water Boiling Test. Pots that were integral to the stoves were used without a lid. Kiln dried Douglas fir at approximately 10% moisture content was burned in all tests. Only one test was performed on the household stoves. Therefore, results are not statistically valid but should be useful for general comparison. The [attached] graphs show results from three Rocket type stoves as compared to a carefully tended Three Stone Fire.

I am member of a student chapter of Engineers Without Borders. We have built two Inkawasi stoves with somewhat disappointing results. (We are still not achieving complete combustion, the sunken pot chambers are problematic for accommodating a variety of cooking utensils, and the smoke escapes from the gap around the pot skirts.) The engineers on the team are discouraged and have given up on the rocket elbow stove design. Though I'm not an engineer, I am skeptical that the stoves were built according to specifications (one was tiny, the other huge); outside engineers who have experience with similar stoves have suggested that our combustion chamber (which was short‹only a little more than 12") was too short.

As seen at ETHOS 2007, we have put together a step be step video on how to build Damon Ogle's design of an Institutional Barrel Stove. The stove is constructed from 200L barrels.

The stove was able to bring 45L of water to boil in 37 minutes using only 2150g of wood.

In a Controlled Cooking Test the Institutional Barrel Stove used 73% less fuel than an open fire!!

The video is available in multiple part downloads here on our website www.aprovecho.org

Schematic Super Turbo Rice Husk Gasifier

Super Turbo Rice Husk Stove (5.5 kW) for Small-Cottage Industry Use
Alexis T. Belonio, Appropriate Technology Center (APPROTECH), Central Philippine University, Ioilo City, Philippines March 28, 2007

Good news and glory to God!

A larger-scale super turbo rice husk stove that injects super-heated steam into the burning chamber was recently developed for small cottage industry use. By injecting super-heated steam into the stove’s burning chamber, a luminous pinkish-flame, which is rich in hydrogen gas, is obtained. While cooking, the stove produces clean gas that is released to the atmosphere.

This technology is another breakthrough in biomass stove research and development of the Appropriate Technology Center of the Department of Agricultural Engineering and Environmental Management, College of Agriculture, Central Philippine University, Iloilo City. This project was collaboratively assisted by the following agricultural engineering students of CPU namely: Daniel Belonio, Lucio Larano, Ian John Fabellore, Mark Alvin Almazan, and Clark Ian Sansolis.

As schematically shown below, the stove consists of a conical hopper that is made of GI sheet no. 16 where rice husk is being fed for burning inside the combustion chamber, a 5 liter capacity steam tank which boils the water and converts it into super-heated steam, a combustion chamber cover having a diameter of 30 cm that also supports the steam tank, a 2-in. diameter air pipe which supplies the air needed for the combustion of rice husk, a char discharge lever that allows the removal of burnt rice husk during operation, a steam burner that is made of 2-in. diameter stainless steel pipe that ignites hydrogen gas from the steam, a 12-mm diameter round bar support to firmly hold the stove, and pot holder to support the cooking pot.

The fan, in this stove, is powered by a TEG. A rechargable battery is used to power the fan during start up. After the the stove has warmed up and heat is supplied to the TEG the fan will now be powered by the TEG. The battery is also recharged by this device. The TEG is located just below the fire box.

Vitagoat Steam Boiler
Malnutrition Matters, Ottawa, Canada

Steam boiler: Operates on wood or other solid fuels or liquid gas. Steam-injected pressure -cooking can be 10 times more fuel efficient than traditional open fire cooking and more efficient than improved stove-design cooking. Water is heated in an inner chamber and the resulting steam is re-heated in a tube, creating a “superheated steam” that is much hotter than regular steam. The steam is then fed into the cooker. The boiler is inexpensive to build, safe, and can be taken apart for cleaning, which is critical since most boilers accumulate scale on their inner shells and eventually fail.

Rocket Stove Questions and Answers: Rocket Stove Air Supply - Primary and Secondary Air

Q.
Dear Stovers,
The fuel magazine that sticks out the side of a rocket stove is divided into two: above the shelf is where the fuel goes, and air passes under the shelf. Am I right in thinking that the fuel should be packed in as much as possible, to try and minimise the amount of air entering the stove through the fuel inlet? If so, why? My experience is that char builds up at the bottom of the elbow, so air is needed to burn the char (which in turn pyrolises the fuel), and a second air supply is required to burn the volatile gases. Any pointers would be warmly received.
Confused, Hugh.
