当锅炉正常运行时,燃料的燃烧必带来受热面炉管上的积垢,烟垢的导热系数较小,致使锅炉的热效率降低,增加能耗。据测定的资料表明,烟垢厚度一毫米,要多消耗燃料6％,烟垢积灰达到2—3厘米时,不仅热交换恶化,排烟温度升高,而且烟道的阻力损失增加,影响锅炉的正常运行,甚至还要被迫停炉清灰垢。常规的清灰垢是停炉后采用人工清刷或蒸汽吹除,这种方法不仅劳动强度大,效率低,有碍工人的身体健康,且清的不彻底,易损伤锅炉,影响生产和安全。使用我厂生
When the boiler is in normal operation, the combustion of the fuel will bring about fouling on the tube surface of the heating surface, and the thermal conductivity of the scale is relatively small, resulting in the reduction of the thermal efficiency of the boiler and the increase of energy consumption. According to the measured data shows that the thickness of a kilogram of tobacco, to 6% more fuel consumption, fouling ash to reach 2-3 cm, not only deteriorated heat exchange, exhaust gas temperature increases, and the loss of flue resistance increases, the impact The normal operation of the boiler, and even have to be forced to stop the furnace cleaning dirt. Conventional cleaning ash is the use of artificial cleaning brush or steam blow off after the shutdown, this method not only labor-intensive, low efficiency, hinder the health of workers, and the clear is not complete, easy to damage the boiler, affecting production and safety .
