    用手摸锅炉的外表面,感知是否发热。如果发热,说明锅炉自身保温效果不好,白白散发掉的热量较多,而这些热量都来自锅炉烧的煤,所以这样的锅炉肯定不会省煤,并且热效率不高。
    The outer surface of the hand touch boiler, perceptions are hot. If fever, boiler heat preservation effect itself is not good, all be escaping heat is more, and these calories come from coal burning boiler, so the economizer of boiler will surely not, and the thermal efficiency is not high. 
    查看燃煤采暖炉烟筒是否冒烟。用眼睛能看到的烟,尤其黑烟,都是燃料,都来自煤中。如果烟筒冒烟,这样的锅炉肯定不会省煤,并且热效率不高。
    Check to see if coal-fired cainuanlu pipe smoking. With your eyes can see the smoke, especially black smoke, fuel, comes from coal. If smoking chimneys, the boiler will surely not province coal, and the thermal efficiency is not high. 
    用手迅速触摸一下燃煤采暖炉烟筒外壁,感知烟筒的排烟温度是否高。如果手烫得受不了,这时的排烟温度应该在200℃以上,说明锅炉浪费掉的热量很多,而这些热量都来自锅炉烧的煤,所以这样的锅炉肯定不会省煤,并且热效率不高。
    Quickly with the hand touch the outer wall of the coal cainuanlu chimneys, perception of pipe smoke exhaust temperature is high. If hand very hot can't stand it when the exhaust temperature should be above 200 ℃, boiler waste a lot of heat, and these calories come from coal burning boiler, so the economizer of boiler will not, and the thermal efficiency is not high. 
    查看燃煤采暖炉炉底的煤渣是否多。如果煤渣多而且多为块状,说明煤的燃烧不充分,煤的热值没有充分利用,这样的锅炉肯定不会省煤,并且热效率不高。
    See if coal-fired cainuanlu furnace bottom of coal cinder. If coal cinder more and more as the block, the combustion of coal is not sufficient, the calorific value of coal is not fully used, the economizer of boiler will not, and the thermal efficiency is not high.
