Computation Methods of Explosion Temperature and Pessure of Combustible Gases

摘要

Two kinds of gas explosion modes are put forward on the basis of analysis and study of gas explosion accidents in this paper. Based on the energy conversation equation of Chemical engineering thermodynamics, it is concluded that the total intrinsic energy of the explosion system is constant before and after the gas explosion. Two computation methods of explosion temperature and pressure of gas explosion in vessels and in the air are built. Comparison of values between computation and literature shows that it is feasible to use the computation methods. Combination with case example the computation methods are explained.
