火焰炉炉膛小炉壁的差额热量为零,它的温度和有效辐射均与其黑度无关,因此完全可以把它看作是绝对黑体.作者利用这一概念,十分简便地导出了众所周知的火焰炉炉膛热交换公式及炉壁温度公式.推导过程简单明暸.炉膛热交换公式中之系数C_(гкм)可以拆成C_(гм)及C_(км)两项,它们的涵义与什维德生公式中的“C_(гм)”及“C_(км)”是不同的,文中作了必要的说明。利用上述同样的概念,推导了火焰炉中热电偶热点温度的公式,并对其他有关的论著作了分析.推荐了计算点与面之间气体平均射线长度的方法,这是在热电偶热点温度的公式中所必须解决的问题.
Flame furnace hearth furnace wall difference between the amount of heat is zero, its temperature and effective radiation are independent of its blackness, it can be regarded as absolute black body. The author of this concept, it is very easy to derive the well-known flame furnace Furnace heat exchange formula and wall temperature formula.The derivation process is simple and clear.Characteristic C_ (гкм) in the furnace heat exchange formula can be disassembled into C_ (гм) and C_ (км) In the “C_ (гм)” and “C_ (км)” is different, the text made the necessary instructions. Using the same concept as above, the formula of the hot spot temperature of the thermocouple in a flame furnace is deduced and other related works are analyzed, and the method of calculating the average ray length of the gas between the point and the surface is recommended, The formula must solve the problem.
