水火管锅壳式锅炉是中国特有的炉型,对推动我国工业锅炉技术的发展,起到了重要作用。该炉型出现不到10年,便使中国80%的锅炉制造厂生产这种炉型,其产量竟占全国工业锅炉总产量的60%以上,并且至今仍长盛不衰,产量仍高达50%左右。水火管锅壳式锅炉出现后,经历过2次大改动,一是针对运行中出现的各种问题,在结构上做了不断的改动,诸如水冷壁管的非径向进入锅筒,改为径向进入;把烟气从锅筒底部小烟室进入烟管,改为由后管板进入等,其典型结构见图1。二是在高等院校科研成果的基础上,1989年起运用10项新技术,使其在结构上、计算方法上做了大的改 Fire tube shell boiler is China’s unique furnace, to promote the development of China’s industrial boiler technology, has played an important role. Less than 10 years after its appearance, 80% of China’s boiler factories produced such furnaces, accounting for more than 60% of the country’s total industrial boilers output and still up to 50% %about. After the fire and water boiler shell and shell boiler, has undergone two major changes, one for the operation of a variety of problems, the structure has been constantly changed, such as non-radial waterwall tube into the drum, to Radial access; the flue gas from the bottom of the smoke into the smoke tube at the bottom of the tube, into the rear tube plate into the other, the typical structure shown in Figure 1. Second, on the basis of the achievements of scientific research in universities and colleges, 10 new technologies were applied since 1989, making great changes in the structure and calculation method
