摘要
介绍了中国工业锅炉现状,锅炉平均容量逐年增加,燃煤锅炉的容量和台数占工业锅炉总容量、总台数的65%左右。对近年来锅炉产品进行了统计分析,结合国家节能减排工作的实施,对在用燃煤工业锅炉存在的问题进行分析。结果表明:锅炉总体技术水平落后,单机容量小;除尘与脱硫技术水平低,燃煤锅炉污染物排放高;自动控制水平低;锅炉用煤质量不稳定,不能满足锅炉设计要求;锅炉节能工作监督和管理体系不完善。提出在城市中心区采用燃油、燃气锅炉或电加热锅炉,推广新型高效煤粉锅炉,对燃煤工业锅炉节能减排改造给以投融资扶持等措施,以提高燃煤工业锅炉效率,减少污染物排放。
The average boiler capacity has been increasing year by year in China, especially the coal-fired boiler, whose capacity and quantity have accounted for around 65 percent of the total capacity and quantity. Based on the national standards of energy saving and emission reduction, analyzed the problems of boiler, especially the coal-fired boilers. The results show that the overall boiler technology is backward, single-boiler capacity is lower and the dust extraction and desulfuration technology is unadvanced. The coal-fired boilers dischage large amounts of pollutant and the automatic control system also can＇t work well. The quality of feed coal is so instable that it can/t meet the demand of boiler designment. The supervision and management systems for boiler energy saving are faulty. In order to resolve those problems, put forward some methods, which are as followed. Encourage the use of oil-fired, gas-fired or electrically heated boiler in urban centers. Extend new types of high efficient pulverized coal boiler. Transform current energy saving and emission reduction technology with venture capital, which would improve the efficiency of industrial coal-fired boiler and reduce pollutant emission.
