我省虽有丰富的煤炭蕴藏量和相当的开采能力,但仍不能满足迅速增长的工农业生产和人民生活的需要。因此如何合理开发和有效利用煤炭资源,最大限度地挖掘潜在的巨大经济效益,是急待解决的课题。由于长期以来供应电站锅炉燃用的煤种不能做到按设计煤种定点供应,燃烧和沾污特性相差很大,这对锅炉的安全经济运行有很大威胁。因此必须从煤炭部门的产、供、销各个环节以及电厂的配煤掺烧等方面共同努力,才能保证电站锅炉的安全经济运行。众所周知,锅炉的设计计算(主要指保证参数——蒸发量、压力、温度等)是根据给定的煤种来进行总体结构、受热面布置和燃烧设备的选配的。因此当煤种变化时,不
Although our province has abundant coal reserves and considerable mining capacity, it still can not meet the needs of the rapidly growing industrial and agricultural production and people’s lives. Therefore, how to develop and use coal resources rationally and maximize potential economic benefits is an urgent issue to be solved. Since long-term supply of coal-fired power plant boiler can not be designed to provide fixed-point coal supply, combustion and contamination characteristics vary widely, which is a safe and economic operation of the boiler is a big threat. Therefore, it is necessary to make joint efforts from the coal production, supply and marketing as well as coal blending with power plants in order to ensure the safe and economical operation of power plant boilers. It is well-known that the boiler design calculation (mainly referring to the guaranteed parameters - evaporation, pressure, temperature, etc.) is based on the given coal type for the overall structure, heating surface arrangement and combustion equipment. So when coal types change, no
