摘要

生铁生产的产物之一是高炉煤气。它的压力能,除其他外,可以通过包括一个膨胀涡轮机与后续生产的电力。文章讨论了计算高炉煤气作为混合气体的热力学量的可能性。理想气体的状态方程在很宽的温度和压力范围内应用得不够精确。理想气体状态方程的不准确性一般随温度的降低和压力的增大而增大。为了验证气体热力学量对压力的依赖性,并在正常条件下计算状态量,我提出了所谓的本尼迪克特-韦伯-鲁宾方程,它可以很容易地推导出来,因此从压力公式可以很容易地得到其他热力学变量的公式,它足够精确,常数的值是为大量气体设定的。

Blast furnace gas as a product of pig iron production
One of the products of pig iron production is blast furnace gas. Its pressure energy can be used, among other things, by including an expansion turbine with subsequent production of electricity. The contribution discusses the possibilities of calculating the thermodynamic quantities of blast furnace gas as a mixture of gases. The state equation of an ideal gas does not apply accurately enough over a wide range of temperatures and pressures. The inaccuracy of the ideal gas state equation generally increases with decreasing temperature and increasing pressure. To verify the dependence of gas thermodynamic quantities on pressure and to calculate state quantities under normal conditions, I present the so-called Benedict-Webb-Rubin equation, which can be easily derivable, so that from the pressure formula it is possible very easily to obtain formulas for other thermodynamic variables, is sufficiently precise and the values of constants are set for a large number of gases.
