我国工业锅炉约有25万台以上,其中以火床燃烧锅炉为主,粉煤锅炉很少。每年耗煤量2亿吨以上,约占全国原煤产量的25%。火床燃烧锅炉对煤炭品种和质量均有一定的要求。但是由于目前供应的煤种不符合原设计要求,造成煤炭损失大,热利用率低。根据有关部门测定,锅炉的实际效率要比设计效率低6—13%。鉴于上述情况,工业锅炉用煤的问题,开始受到 There are about 250,000 industrial boilers in China, of which the main is the combustion bed boiler, with very few pulverized coal boilers. Annual consumption of more than 200 million tons of coal, accounting for about 25% of the country’s coal production. Fire bed combustion boiler on coal varieties and quality have certain requirements. However, due to the current supply of coal does not meet the original design requirements, resulting in large coal losses, low heat utilization. According to the determination of relevant departments, the actual efficiency of the boiler is 6-13% lower than the design efficiency. In view of the above, the problem of coal used in industrial boilers began to suffer
