以底部烧气单侧立管圆筒型加热炉为研究对象,建立了燃烧区内高温火焰对炉管外壁的辐射热流强度的数学模型,并且给出计算实例,分别采用复形调优法和对分法解出炉管外壁向火面上最高热强度点的大小及其位置,两种计算方法的结果一致。最后对炉管在加热炉内的优化布置作了一定的探讨;对于多管程的圆筒炉,各管程的出口炉管不应该布置在来自高温焰烟的辐射热流强度较高的区域空间内。其计算实例为分析其它炉型提供了方法。
Taking the unilateral riser-cylinder heating furnace at the bottom of the furnace as the research object, a mathematical model of the radiant heat flow intensity of the high-temperature flame in the combustion zone to the outer wall of the furnace tube was established and the calculation examples were given. The solution of the points out of the furnace wall to the maximum heat intensity on the fire point size and location, the results of the two methods are consistent. Finally, the optimal arrangement of the furnace tube in the heating furnace is discussed. For the multi-tube cylindrical furnace, the outlet tube of each tube should not be arranged in the area of high radiant heat flux from high temperature flame smoke Inside. The calculation example provides a method for analyzing other furnaces.
