摘　　要：在生物气的利用中,其热物性参数是各种工艺设计计算的基础;然而生物气是复杂的气体混合物,如垃圾填埋气含有140多种化学物质;并且生物气的组分、压力、含水量都是变化的参数,实际计算十分复杂。提出了一种富水生物气热物性的计算方法,能够满足一般工程设计和分析的精度要求;并采用计算机语言编程,实现智能化计算不同组分比和变压力工况下生物气的热物性参数。In the utilization of biological gases,the thermal physical parameters are the foundation of all kinds of process design and calculation.However,biological gases are complex gas mixtures,for example,landfill gas contains more than 140 kinds of chemical substances,and the component,pressure,and moisture content of the biological gases are varying parameters,which make the calculation very complex.A calculation method was proposed to calculate the thermal physical properties of the wet biological gases and could satisfy the requirements of general engineering design and analysis,by which the thermal physical properties of the biological gases with different component ratios and pressure could be intelligently computed by computer language programming.
