一、要注意煤种适应性。因为锅炉机组的设计是以某一代表性煤种的成份为依据的,因此在选用时要注意适应术地区的煤种。二、要注意参数选择。锅炉一般在额定负荷的80％～90％时效率最高,随着负荷的下降,效率也要下降。一般选用锅炉的容量比实际用汽量大10％就可以了。如选择的参数不正好是系列标准,则选用较高一档参数的锅炉。锅炉 First, we must pay attention to coal adaptability. Because the design of the boiler unit is based on the composition of a representative coal, it is important to pay attention to the type of coal suitable for the operation area. Second, pay attention to parameter selection. Boilers generally have the highest efficiency at 80% to 90% of rated load, and the efficiency decreases as the load decreases. General use of the boiler capacity than the actual use of steam 10% larger on it. If the choice of parameters is not exactly a series of standards, the choice of a higher boiler parameters of the file. boiler
