高海拔地区660MW机组锅炉热负荷参数选取
|
摘要
目前,我国海拔高度超过2 500m的地区,尚无600 MW及以上等级大容量高参数机组锅炉的设计和运行经验。本文利用模拟试验台测得在2 900mm高海拔低气压条件下,鱼卡煤的着火温度和燃尽率等燃烧性能参数,同时结合目前大型机组的设计特点,提出了在2 900m高海拔条件下660MW机组锅炉的热负荷参数推荐值,可为高海拔地区大容量高参数锅炉设计提供依据。
Currently,the boiler design and operation experience for 600 MW unit boiler with large capacity and high parameters is empty in the areas with altitude above 2 500 m.In this paper,a simulation combustion test under conditions with high altitude and low air pressure was carried out to obtain the ignition and burnout characteristics of coal samples.Considering the gas expansion characteristics under high altitude and low air pressure condition and the design features of current large scale units,tthe recommended heat load parameters for a 660 MW boiler lying in the area with altitude of 2 900 mare proposed,which can provide references for by large capacity and high parameters boilers' design in high altitude areas.
