METHOD FOR OPERATING A FURNACE OF A COAL-FIRED POWER STATION

摘要

The invention relates to a method for operating a furnace of a coal-fired power station, in particular a hard coal power station, which furnace comprises a steam generator which is equipped with coal dust burners and of which the coal dust burners are components of an indirect firing system comprising at least one coal mill with a coal dust bunker connected downstream, wherein a solution should be created which enables flexible operation of a coal-fired power station and to increase the net efficiency for a coal-fired power station which is kept ready for operation. This is achieved in that the furnace is operated temporarily during the operating time thereof in a standby mode, in which the furnace is operated in a minimum load range or minimal load range of the steam generator and energy which is generated during operation and is not fed or not to be fed into the power supply system connected to the power station is used for the preparation of raw materials or fuels required for operation, in particular for operating the at least one coal mill, and/or stored in at least one installation preferably integrated into the power station and/or used in the context of combined heat and power.
