CharBowl charcoal stove

19 November 2011 - 10:45am

On a recent trip to Haiti I was finally able to construct my CharBowl(tm) charcoal stove. It uses two nested stainless steel bowls (5 quart and 8 quart (4.7 liters and 7.6 liters))for durability and reflectivity with castable insulating refractory between them to reduce conductive heat losses. It has a 6.5" (16.5cm) dia cast iron grate for durability. It has a secondary air pipe to reduce CO emissions and increase heat output. The secondary air outlet pipe is 3/8" (10 mm) nominal (ID 0.493" 12.5mm; OD 0.675", 17mm) black iron with a Tee fitting on top to keep charcoal from dropping into it. 3/4" NC 10 (19mm 2.5) machine threads were cut over the pipe threads. This allowed the use of a split nut and flat washer inside and outside the bowls to hold the bowls together. The elbow is 3/8" to 1/2" . The inlet pipe is nominal 1/2" iron (ID 0.622" 16mm; OD 0.84", 21mm). The bowls sit on a stock pot base for stability and primary air control. (I couldn't get my hands on the stainless pot I really wanted to use for the base. I'm planning to build another with such a base now that I'm back in the States.)
I hope to get some testing done on my second prototype.
It can be used as the base of a TChar stove.Nike Air Force 1 '07 Lv8 Utility White/White-Black-Tour Yellow – nike dunk high pro sb kentucky derby 2017

GEO CAMP FIRE STOVE

From GEO CAMP FIRE STOVE

This a low cost simple tin can of less $ 0.5 , with primary and secondary air facility to use for efficient camp fires and also for cooking on it. One need to strive for using the best and efficient stoves, but for the poor, and unavoidable situation / emergencies, such simple tools can be used.
This design is incidental, I have prepared lots of tin cans for Magh CL stove http://e-mcl.blogspot.com/, this winter it had been too cold, during the nights for warmth these tins were used, the efficiency was very high as compared to the open campfires and it was comfortable to use it everywhere. The primary and secondary air helped in complete combustion. Using it for cooking from camp fire mode was also convenient, by just putting on top a concentrator slab and pot rest. During cooking the fuel was fed from the side openings. The wood fed is vertical to slant, this helped in convenient combustion. While cooking was done the radiation of heat was enough for warmth.

Biomass Gasification Boiler Technology Evolves

19 October 2011 - 11:16am

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”
