Blocked generators for energy and industrial heat waste use

The results of 200 kW thermoelectric generator developments of liquid-liquid type have been given. Operating temperatures are the following: hot side temperature is 250°C, cold side temperature is 50°C. Heat transfer from a source is effected by high temperature liquid circulation. Heat removal from the generator is effected by water circulation. The generator is arranged from 400 blocks of 500 W each. A block volume is about 15 liters, its weight is about 15 kg. Specially designed highly effective heat exchangers together with Altek 1018 thermoelectric modules specially designed for that purpose have been used in the blocks. The generator´s efficiency is about 6%. The generator´s reliability is about 600 times greater than the reliability of known analogues. Depending on heat source, power generators of required power can be developed on the basis of such blocks. The generators are designed for utilization of waste heat from internal combustion engines, gas turbines, garbage combustion and from other industrial heat waste
