摘要
排烟温度偏高会造成锅炉效率下降,影响锅炉运行的经济效益。对国华电力公司某电厂600MW亚临界锅炉燃用神华煤锅炉结焦、尾部受热面积灰原因进行分析。指出影响排烟温度高的因素主要有锅炉系统漏风、炉内燃烧区域的合理燃烧、制粉系统的运行方式以及掺冷风量的多少,并提出相应的对策。实践表明排烟温度达到设计值,锅炉运行效率超过设计值。
High temperature of flue gas can decrease the efficiency of boiler and power plant.The main factors influencing the temperature of flue gas, such as air leakage into furnace, proper burning in the furnace, the operating mode of coal pulverizating sys- tem,the amount of the cold air is analyzed and the corresponding measure is put forward.The operation Shows that the temperature of flue gas is reduced and the efficiency of boiler rose.
