我国自行开发的水火管锅炉,现已出现第三代产品——组合螺纹烟管锅炉(非锅壳式)[1]。组合螺纹烟管锅炉是在我国大量应用30载并积累相当丰富经验的新型水火管锅壳锅炉[2]基础上,发展起来的一种崭新锅炉炉型,如图1所示。组合螺纹烟管锅炉与一般水管锅炉的主要区别体现在对流受热面:前者为数个拼在一起的两排高效传热螺纹烟管筒——高温烟管筒与低温烟管筒,而后者为被炉墙包围起来的排管、蛇形管、旗片U形管等。
China’s self-developed water and fire tube boiler, now appears the third generation of products - combined thread tube tobacco (non-shell type) [1]. The combined thread smoke tube boiler is a new type of boiler furnace developed on the basis of a large number of 30-year-old accumulated boiler tubes with rich experience in China [2], as shown in FIG. 1. The main difference between the combination thread smoke tube boiler and the general water tube boiler is the convection heating face: the former is a series of two rows of high-efficiency heat-transfer thread tube housings - the high temperature smoke tube and the low temperature smoke tube, Furnace wall surrounded by the drainage pipe, serpentine pipe, flagship U-shaped pipe.
