我国工业采用沸腾燃烧锅炉始于60年代后半期,目的主要是着眼于解决地方性低质燃料的有效燃烧问题,如洗煤副产物、矸石、低质烟煤、无烟煤、褐煤以及油页岩、石煤等。这些燃料都很难在常规燃烧方式的小容量锅炉上稳定燃烧,而沸腾燃烧则发挥了它的独特的优越性。因此,在过去的十几年内,小沸腾燃烧锅炉得到了相当的发展,尤其是在工业锅炉方面。当然,它们的容量是有限的;单炉蒸发量一般只在5～15T/h范围内甚至更小些。这些小沸腾锅炉多半是由各行业自己设计制造或改装的,部分是由地方小锅炉制造厂家生产的。虽然经过几代改进,在运行的可靠性及煤种的适应性上取得了一定的进展,但总的说来,设计和运行水平仍然是较低的。
China’s industrial use of boiling boilers began in the second half of the 1960s, the main purpose is to solve the problem of local low-quality fuel combustion problems, such as coal washing by-products, waste rock, low bituminous coal, anthracite, lignite and oil shale, Wait. These fuels are difficult to stably burn on small-capacity boilers with conventional combustion, while boiled combustion exerts its unique advantages. As a result, small boilers have seen considerable progress over the past decade or so, particularly in industrial boilers. Of course, their capacity is limited; single-boiler evaporation is typically only 5-15 T / h or less. Most of these boil-up boilers are designed, manufactured or retrofitted by industries themselves, and partly by local small boilers manufacturers. Although several improvements have been made, some improvements have been made in the reliability of operation and the adaptability of coal types, the overall design and operation levels are still relatively low.
