The role and significance of power coal blending technology (1) Ensure that coal-fired characteristics match the design parameters of coal-using equipment, improve equipment thermal efficiency, and save coal; (2) Guarantee the stability of coal quality through “homogenization†and use normal and efficient operation of coal equipment; (3) Make full use of low-quality coal or local existing coal resources to make the best use of them and improve social benefits; (4) Adjust the content of sulfur and other harmful substances in coal combustion to meet environmental protection requirements. In general, the power coal blending plant consists of the following processes, the principle process is as shown below. (1) For the acceptance and storage of raw materials, the main equipment used is the rolling dragon reclaimer, the ground dragon scraper and the bucket wheel reclaimer. (2) Screening, screening, controlling the coal blending particle size, and screening out lump coal, adding certain economic benefits to the coal plant. The common screening equipment has a drum screen and a vibrating screen. (3) Compounding is an important process for power coal blending. It is generally divided into two types: weighting and volumetric. The main equipment for volumetric ingredients is the disc feeder and the tape batching machine. The weighting ingredients are generally electronic belt scales.

Any type of boilers and furnaces have certain requirements on the quality of coal, under current conditions, to improve the thermal efficiency of the boiler, it is necessary to ensure efficient operation of the boiler to normal, and the characteristics of coal-fired boiler design parameters match. It is difficult to achieve the best results if the coal quality is too high or too low. Under the premise of meeting the coal quality requirements of coal-fired equipment, the use of power blending technology can maximize the use of low-quality coal, or more fully utilize the existing local coal resources. The mutual cooperation of different quality coals can also adjust the sulfur content of coal combustion and the content of harmful elements such as nitrogen, chlorine, arsenic and fluorine according to the requirements of different regions on the atmospheric environment and water quality, and reduce the emission of SO2, NOx and harmful elements. Limit the environmental protection requirements.
