Slagging is a major operating problem in application of the atomization–suspension combustion technology for burning coal water slurry (CWS) fuel in small and low height industrial boilers. The fluidization–suspension combustion is a new alternative for replacement of oil, which is capable of solving the slagging problems. In addition, it can be successfully applied to CWS-fired boilers with capacity smaller than 35 t/h. About 530,000 medium and small scale industrial boilers with low boiler efficiency in China provide the technology a very promising prospect. The principles and contents of CWS fluidization–suspension combustion technology are introduced in detail in this paper. And a new type of 14 MW fluidization–suspension CWS-fired boiler was developed, the performance of which showed that boiler efficiency was 91.53%. Emission of SO2 and NOx was 346.1 mg/m3 and 469.5 mg/m3, respectively. From the application, the CWS-fired boiler showed good features such as high efficiency, low pollutant emission, good load regulation, good CWS quality adaptability, steady operation and convenient maintenance. 相似文献

中国燃煤工业锅炉现状 总被引:5,自引:0,他引:5
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。 相似文献
