Coal plus refuse burning power station - has refuse-fired boiler steam fed into coal-fired boiler system after high-pressure turbine, before reheater

摘要

The power station runs on ordinary fuel, partic. hard coal-, plus refuse. There is a fuel-fired main boiler serving a turbine set with an HP- followed by one or more lower pressure turbines, and refuse burning facilities releasing heat utilised in the turbine set. The refuse-fired boiler steam side is connected to the inlet of a reheater between the high pressure and the other turbines, and to at least one steam user system fed from the turbine set via a pass-out line. The refuse-fired boiler may have an auxiliary boiler in parallel and/or may be supplementary firing.
