a coking coal, uksztaltowany polprodukt coal to use him in this way and the furnace coke oven for carrying out this method

摘要

Coal, either as coal fines or as coal briquettes, is introduced into a coking chamber and is thereat exposed to microwave radiation to transform the coal into hot coke. Preferably, the microwave radiation is at a frequency of from twenty to 3000 MHz. The hot coke is then passed to a cooling zone whereat photocells absorb radiant energy from the hot coke and transform the thus absorbed radiant energy into electricity.
