导出换热方程式,引出热价值定律,证明在换热装置的不同截面上引入热量,依附于气体或料块,具有不同的热价值。以气体——料块逆流换热为基础,推及其它。 分析了燃料燃烧、炉子构造和操作中的一些问题,诸如热负荷、生产率、理论燃烧温度、火焰长度、烧咀分布、吸风、溢气和装料等方面的问题。区别对待了炉子热平衡中各种热收支以及炉内热量的转移对料块加热的影响。以高炉为例,拟定了高炉换热原则。
The equation of heat transfer is deduced and the law of heat value is derived to prove that heat is introduced on different sections of the heat exchange device and attached to the gas or material block with different thermal values. Gas - block countercurrent heat transfer based on the push and others. Some problems in fuel combustion, furnace construction and operation, such as thermal load, productivity, theoretical combustion temperature, flame length, burner distribution, aspiration, aspiration and charge, were analyzed. Different treatment of the heat balance in the furnace heat balance and the transfer of heat in the furnace block the impact of heating. Take the blast furnace as an example, draw up the principle of blast furnace heat exchange.
