Abstract:Abstract: in view of the particularity of the geological structure in Guizhou, Electric enterprises are widely used to purchase electric coal, and the coal quality index is different, and it deviates seriously from the design of coal, the overall situation of coal is characterized by low quantity and high price, which brings great potential risks for the stable combustion of boilers and the emission of environmental protection standards, A power plant combines the management experience of co-firing with coal blending in recent years, Coal blending and co-firing work should be carried out around the demand of coal and coal quality, In order to carry out equipment transformation and coal blending test, the coal blending is carried out with the standard of stable operation of boiler and standard of environmental protection, which formed from the economic coal procurement into the factory, according to the demand of coal blending furnace, furnace combustion the feedback and adjustment of furnace coal blending, proposed coal procurement needs standardization of coal blending process, It provides a new way for exploring Guizhou thermal power generation enterprises to reduce production cost, and improve the economic benefits and competitiveness of enterprises, and promote regional economic development.
