Operation of several compact combustion chambers was studied experimentally, and it was found pos sible to maintain uniform exit-gas temperatures of 1100 C to 1225 C when firing charcoal, green wood, animal dung, and small grains. A simulated internally fired thermoelectric unit containing a heat meter and calorimeter, and with thermal characteristics simulating those of a thermoelec tric unit, was designed and tested. Heat-transfer effectiveness was far higher than in previous units, ranging from 58 to 74 this compares with corresponding values of 18 to 30 for previous units. This performance permits design of a thermoelectric unit, based on lead telluride technology, having thermal efficiency of about 3.0 3.5. Author
