气体在高炉内的功取决于三种能,即机械能、热能和化学位能。为了研究对高炉冶炼过程的影响,必须根据物理和化学的基本定律,用相同的测试系统以求探明上述能量类型及其相互关系。气体的机械能在闭路循环系统内的守恒定律可用下式表述: Zγ+P+ω~2γ/2g=const (1) The work of gas in a blast furnace depends on three energies: mechanical energy, thermal energy and chemical potential. In order to study the impact on the blast furnace smelting process, the same test systems must be used to ascertain the above types of energy and their interrelationships based on the basic laws of physics and chemistry. The law of conservation of the mechanical energy of a gas in a closed-circuit system can be expressed as follows: Zγ + P + ω ~ 2γ / 2g = const (1)
