多种燃料多级燃烧的燃气热力性质简捷算法

CONCISE CALCULATION OF COMBUSTION GASTHERMAL PROPERTIES OF MULTIPLE FUELAND MULTISTAGE COMBUSTION

文献[1]给出了计算烃型燃料C8H16燃烧产物热力性质的方法，文献[2]把它推广到C-H-O-N′-S类型任意燃料．本文在上述基础上，推出能计算多种任意C-H-O-N′-S类型的气体、液体或固体燃料(含不可燃组分)混烧或多级燃烧后的燃气热力性质的简捷方法．

The concept of equivalent system fuel is introduced in this paper for the complicated conditions of any kinds of C-H-O-N'-S gas, liquid or solid fuel as well as multistage combustion based on the mathematical expression of combustion gas thermophysical properties in reference [2] . The expression of enthalpy, exergy and equivalent fuel molecular formulae is derived under arbitrary β(β≤1), temperature (T= - 50-1500℃) and pressure according to Dalton's rule and combustion balances etc. The error analyses to standard fuel C8H16 are also presented.
