250 Gasifier

22 April 2010 - 2:11pm

Paul Olivier, April 2010

Today we put in operation for the first time the 250 gasifier with a stove top.
This gasifier has a single 2-inch pipe that vents housing air to a warmer grate.
This pipe had no butterfly valve or other restriction.
We used the same small 80x80 mm fan as in the 150 gasifier.
This fan had no problem at all supplying air to the reactor and to the 2-inch pipe.
The burn lasted almost an hour on rice hulls, even though the height of the reactor was no more than 70 cm, the same height as in the case of the 150 stove.
The warmer grate had sufficient heat from the housing to fry an egg, as indicated in picture 855.
We obtained a bright blue flame, as shown in picture 865,
although the camera did not have the right lighting to display it properly.
The stove top was not properly reinforced when a large pot filled with water was placed on top.
There was a deflection of a few mm's.
However this can be easily remedied with two more lateral braces underneath the stove top.
In conclusion, the 250 gasifier works well and delivers an enormous amount of heat.

This is a stove seen by Dulguun Basaandavaa at Suhkbaatar Square which is a huge plaza in downtown Ulaanbaatar. There was a demonstration of stoves in yurts (gers) a few days ago.

This one is particularly interesting for the reason that it is the first small scale Mongolian coal gasifier spotted in the wild. It has a fan so it may be modelled on a much larger device. I have no idea at all how it works. Perhaps someone far more knowledgeable about gasifiers can spot and name the components.

In all more than 10 new stoves were shown nearly all of which are downdraft stoves, or which can be started in updraft mode and switched to downdraft.
One of them was the previously reported BLUD stove from Inner Mongolia that rotates and becomes a TLUD during the ignition cycle.

[MAGH 3G]( http://e-magh3g.blogspot.com/ ) is an adaptation stove. All types of biomass, briquettes and charcoal can be used for cooking. This is an all in one stove.

It was found that many families have at least two or three types of stoves in rural areas for using types of biomass as fuel. Now with just one stove they have the freedom to use all types of Biomass as fuel.

There is an option to control primary air, to control air from the fuel feed side opening, and secondary air (while using TLUD adopter). Weighs less than 2 kgs, 9 inches in height and 7 inches diameter. Most convenient for regular use, travel, relief, refugees, etc. Reusing metal sheet, these stoves are completely hand made. The cost of each stove piece is $5 (USD).

This stove is being facilitated under the "Good Stoves and Biochar Communities" Project, implemented by GEO with the support of GoodPlanet.org This is one of the 40 stoves designed by Dr. N. Sai Bhaskar Reddy, GEO http://www.e-geo.org http://www.goodstove.com/ . For more details visit http://e-magh3g.blogspot.com/
