链条炉是古老的机械层燃炉之一。由于它具有结构简单和操作方便等优点,目前在我国中小型工业锅炉中链条炉被广泛采用,并在机械化锅炉中占有重要的地位。然而,链条炉对煤种有一定的适应性。我国煤质资源丰富,但煤质差异很大,煤质的变化将使锅炉出力和效率下降,尤其是在燃烧热值偏于下限的燃料时,就必须采用措施解决着火、排渣等问 Chain furnace is one of the oldest mechanical layer furnace. Due to its simple structure and convenient operation, it is widely used in small and medium-sized industrial boilers in our country and occupies an important position in mechanized boilers. However, the chain of coal has some adaptability to coal. China is rich in coal resources, but the quality of coal is very different. The change of coal quality will make the output and efficiency of the boiler drop. Especially when it is burning the fuel whose heating value is lower than the lower limit, measures such as fire and slagging must be taken
