Enthalpy and Combustion Temperature of C,H,O,N System

根据函数关系设计出一种表格,任何只含C,H,O,N 4种元素的可燃物质在标准大气压下与氧,空气或者任意比例的氧,氮混合物或化合物按化学计量比进行绝热燃烧时达到的温度都可精确地查得.本表还可用于非绝热燃烧过程的计算.

At standard atmospheric pressure,the adiabatic combustion temperature of any system which contains 4 elements,C,H,O,N,mixed with stoichiometric amounts of oxidant to form H_2O,CO_2 and N_2 gas completely,is a function of 3 variables.If the mole composition of the system can be expressed by C_iH_kO_iN_m and the oxidant contains only N and O with the mole ratio N/O=Q and the initial enthalpy of the fuel-oxidant mixture is H_0,then the above-mentioned 3 variables may be chosen as follows: 1.Reduced enthalpy of the mixture L = H_o/(i+k/3) 2.Mole fraction of H with respect to C+H,M=1OOk/(i+k) 3.N/O ratio in the mixture G=[Q(2i+k/2-j)+m]/(2i+k/2) In this paper the function T=T(L,M,G) was tabulated by a computer.Using this table,the combustion temperature of above-mentioned system can be easily and precisely calculated either in adiabatic or in nonadiabatic processes.
