Abstract
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.
Claims22
A process for coking coal, said process comprising:
- introducing coal to be coked into a coking chamber;
- exposing said coal within said coking chamber to microwave radiation only, and thereby forming said coal into hot coke;
- and
- withdrawing said hot coke from said coking chamber, introducting said hot coke into a cooling zone, and at least partially cooling said hot coke within said cooling zone to form cooled coke, said cooling comprising exposing photocells to said hot coke, whereby said photocells absorb radiant energy from said coke and transform the thus absorbed radiant energy into electricity.

An apparatus for coking coal, said apparatus comprising:
- a coking chamber;
- means for introducing coal to be coked into said coking chamber;
- means operatively associated with said coking chamber for exposing said coal within said coking chamber to microwave radiation only and for thereby forming said coal into hot coke;
- a cooling zone adjacent said coking chamber, whereby said hot coke passes from said coking chamber to said cooling zone;
- and
- means at said cooling zone for at least partially cooling said hot coke to form cooled coke, said cooling means comprising photocell means for absorbing radiant energy from said hot coke and for transforming said radiant energy into electricity.
