摘要
冬季、春季时节,大量的湿煤(全水分10%以上的煤种)集中进厂,给卸煤设备、输煤设施、原煤仓、给煤机制粉系统带来了较大的影响,湿煤也是各家火力发电企业配煤掺烧中不可突破的瓶颈。该文从卸车环节、煤场管理、配煤掺烧、制度措施这4个方面介绍了目前大量使用湿煤的方式。通过湿煤掺烧实践,减少湿煤对输煤系统以及给煤制粉系统的影响,确保机组运行情况稳定,从而降低火力发电企业的燃料成本,拓宽机组使用的煤种。
In winter and spring,a large amount of wet coal(more than 10%of the total water content of coal)is concentrated in the plant,which has a great influence on coal unloading equipment,coal conveying facilities,raw coal bunker and coal pulverizing system,wet coal is also the bottleneck which can not be broken in blending and burning of coal in various thermal power enterprises.This paper introduces the ways of using large amount of wet coal from the aspects of unloading,management of coal yard,blending and burning of blended coal and system measures.Through the practice of mixing wet coal with wet coal,the influence of wet coal on coal handling system and pulverized coal feeding system is reduced,and the stability of unit operation is ensured,thus the fuel cost of thermal power plant is reduced and the type of coal used in unit is broadened.
