摘要

针对某发电公司2台锅炉存在过热器和再热汽温偏高、减温水量大、锅炉安全稳定性差的问题

通过对锅炉尾部受热面进行改造

增加省煤器受热面的吸热量

减少了过热器、再热器的吸热量

达到了降低减温水量的目的。改造结果表明:减温水量减少到100 t/h

比改造前大大降低

提高了锅炉运行的安全稳定性及经济性。

Abstract

Aiming at the temperature of the superheater and reheater was higher

the volume of desu?perheating water was large and safe stability of the boiler was poor

in two boilers of a power genera?tion company

through improving the heating surface of boiler afterbody

increases heat absorption ca?pacity of heating surface of economizer

reduces heat absorption capacity of superheater and reheater

reaches the aim of reducing the volume of desuperheating water. The result shows that the volume ofdesuperheating water is 100t/h after the improvement

reduces greatly than formerly

promotes safe sta?bility and economy of the boiler’s operation.
