高海拔低气压条件下制粉系统选型
摘要
某高海拔地区拟建2台超超临界660 MW烟煤机组
该区域气压及空气密度均较低。根据相关规程
结合该区域的气压、气象特点对制粉系统进行了相关计算
提出高海拔条件下制粉系统选型的方法
并根据制粉系统所需研磨出力、干燥出力及通风出力的计算结果推荐选用ZGM133N型中速磨煤机。
Abstract
Two 660MW ultra supercritical units firing bituminous coal were planned to be built in a high altitude area.According to the relevant rules and combing with the ambient pressure and atmosphere characteristics
relevant calculations on the pulverizing system were performed.Type select method for the pulverizing system was put forward.Moreover
on the basis of the calculation results of the grinding force
drying capacity and ventilation output that the pulverizing system needs
