摘要
介绍了75 t/h循环流化床煤泥锅炉本体、辅机的技改经验,改造后锅炉的出力、热效率达到设计值,并且减少了对空预器和省煤器的磨损,循环倍率得到提高;通过对烟风道的结构改造解决了强度低、运行漏风的问题。锅炉技改方案的成功实施使锅炉出力和运行稳定性得到显著提高。
Technical modification for 75t/h circulating fluidized-bed boiler of coal slurry was introduced in this paper. After technical modification, the boiler output power and thermal efficiency achieved the one expected with a reduction of wear attrition to boiler surface and increase of circulating ratio. The problems of low intensity and air leakage were solved through reforming the structure of gas duct. The success of technical modification made a remarkable increase of boiler output power and stability.
