BLAST FURNACE GAS AS A PRODUCT OF PIG IRON PRODUCTION

Popis výsledku v původním jazyce

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.
