Abstract (en)
[origin: US6067914A] A method of operating a combustion unit of a coal-fired power plant operating according to a slag tap furnace firing method, which includes supplying a titanium-containing material in addition to coal to a melting chamber for accelerating coal burn-up, burning the titanium-containing material together with the coal in the melting chamber at a temperature above 1500 DEG C., and generating fly ash and molten ash as a result of combustion in the melting chamber. Additionally, a combustion unit for a coal-fired power plant, including a melting chamber that has a combustion zone for receiving coal. The combustion zone produces fly ash. The combustion unit also includes a separate feed line for supplying a titanium-containing material to the combustion zone for accelerating burn-up of the coal and a second separate feed line first to supply a titanium-containing material to the fly ash and then supply the titanium-containing material and fly ash combination to the combustion zone for accelerating burn-up of the coal and fly ash.
