Abstract

An entrained bed combustor may provide constant temperature, superheated steam to a power generating steam turbine independent of the load on the turbine. In a conventional utility boiler heat is transferred in series to the steam generator, superheater and reheater. With the present invention these components may be run in parallel with heat transfer from the entrained bed particles enabling faster start-up and a turn-down capability without a reduction in the superheated steam temperature.
