    1.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。

    The more detailed the better: 1 coal particles from the burning point of view, the coal particle more fine more easily with air to form good mixing, burning more fully. But the coal particle is too small, the power station boiler, electric energy consumption will increase greatly.

      2.燃料加得越多越好:有人认为数控锅炉的煤加得越多产汽量就越大。殊不知过多的煤进入炉膛,效果会适得其反。煤与空气的重量比宜为1∶9.14。当空气量一定而燃料量过多时,炉内就会产生大量的不完全燃烧物,如一氧化碳等。人们常常见到炉膛火焰发暗、无力,且烟囱冒黑烟,大都是这个原因。严重时,煤粉炉会出现灭火,油炉会出现二次燃烧、爆管直至停炉。所以,燃料与风量的配比应调节得当,通常可通过看火、看烟色、看氧量表指示来确定。

    2 fuel increases the more the better: some people think that the CNC boiler coal add more prolific steam amount is higher. Not knowing too much coal into the furnace, the effect will be run counter to one's desire. The weight ratio of coal and air should be 1: 9.14. When the air amount and the amount of fuel in the furnace is overmuch, can produce a large amount of incomplete combustion, such as carbon monoxide. People often see the furnace flame dark, weakness, and the smoke from the chimney, mostly for this reason. Serious when, pulverized coal furnace will be fire, oil will appear two times, until the shutdown of the boiler tube explosion combustion. Therefore, the fuel and air ratio should be adjusted properly, often can see through the fire, smoke, see the oxygen meter to determine.

      3.数控锅炉的水位越高越安全: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。

    Table 3 CNC boiler safety: some people think that the higher water level is high, the boiler is not easy to dry, safety has safeguard. However, it is a kind of wrong understanding. Water level is too high, the steam humidity increased, the steam quality is bad, it will endanger steam equipment and production.
