摘要
生物质能是一种可再生、对环境友好和利用过程中二氧化碳零排放的能源资源, 所以研究生物质气化发电技术意义重大。在烧生物质燃料气的燃气轮机性能计算中, 需要使用生物质燃料气的燃气热力性质数据, 如果将其比热视为常数或采用平均比热都会引起较大误差, 因此需要基于变比热的生物质燃料气的燃气热力性质计算方法。生物质燃料气属于含有不可燃成分的混合气体燃料, 因而将基于变比热的混合气体燃料(含不可燃成分)燃气热力性质的计算方法应用于变比热的生物质燃料气的燃气热力性质计算, 并且用Delphi6 0开发了计算程序。通过对烧某一生物质燃料气的LM2500型燃气轮机的某一工况点热力性能计算, 对该计算方法和程序进行了验证。结果表明, 混合气体燃料(含不可燃成分) 燃气热力性质的计算方法可以应用于生物质燃料气的燃气热力性质计算, 编制的计算程序为烧生物质燃料气的燃气轮机性能计算提供了解决方案。
As bioenergy is a renewable, environment\|friendly and zero net carbon dioxide emission energy source, research on biomass gasification power generation technology is of great significance. For a more accurate calculation of characteristics of gas turbines using biomass fuel gas, the data of thermodynamic properties of the products of combustion of biomass fuel gas with air have to be used because if a constant specific heat capacity or an averaged specific heat capacity is used in the calculation, the error could be very big. Due to the fact that biomass fuel gas belongs to the mixed gaseous fuel with incombustible gases, the calculation method for the products of combustion of the mixed gaseous fuel with incombustible gases is adopted in the calculation method for the products of combustion of biomass fuel gas with air. The calculation program was coded in Delphi6.0. The calculation method and program are verified by the thermodynamic performance of a LM2500 gas turbine using biomass fuel gas at a given operational condition.
