Slag Tap Combustion Method of Combustor in Coal Fueled Power Plant and Combustor Operated accordingly

摘要

In the combustion units of coal-fueled power plants, the dust carried by the flue gas contains up to 50% combustible material. In order to achieve high efficiency by complete combustion, dust is returned to the combustion chamber in a slag tap combustion coal fueled power plant. However, this increases the average residence time of coal or dust particles in the combustion circuit. According to the present invention, there is provided a method of operating a combustion device of a slag tap combustion type coal fueled power plant, and a combustion device having a slag tap operated according to the present invention, wherein a material containing titanium is supplied in addition to coal to promote complete combustion of coal. Is provided. Thus, the throughput of the fuel is increased, and as a result, the efficiency of the power plant is increased.
