    锅水水位越高越安全。有人认为水位高一些,锅炉就不容易缺水,安全性就有保障。然而却是一种错误认识。水位过高,蒸汽湿度加大,蒸汽品质不良,就会危害用汽设备和生产。
    Boiler water level is higher the more security. Some people think that water level higher, the boiler is not easy to water shortages, security is guaranteed. But it was a misunderstanding. Water level is too high, the steam humidity increase, poor quality of steam, will harm and steam equipment production.
    煤粒越细越好。从燃烧角度看,煤粒越细就越易与空气形成良好混合,燃烧越完全。但煤粒过细,对电站锅炉而言,制粉电耗将大大增加。
    Coal particles as thin as possible. From the perspective of the burning coal grain of the thinner the more easily mixed with air to form good, burning more completely. But coal grains carefully, for power plant boiler milling power consumption will increase greatly.
    蒸汽压力越高越好。数控锅炉蒸汽压力的选定,主要取决于用户的需要。汽压低,对承压部件的安全有利,能耗也低,但蒸汽的品质就差,热焓低,湿度也大,甚至难以满足消毒、杀菌、培养、采暖和发电的需要。
    The higher the steam pressure, the better. Numerical control boiler steam pressure selected, depending on the needs of its users. , and good for the safety of the pressure parts, low steam consumption is also low, but the steam quality is poor, low enthalpy, humidity is big, difficult to meet even disinfection, sterilization, cultivation, heating and power generation needs.
