摘　　要：生物质和城市垃圾等复杂燃料是重要的可再生能源,因化学组成复杂,无法精确计算燃料的焓和[火用],需根据模型估算。但现有模型难以同时、准确地估算复杂燃料的焓和[火用],存在违背[火用]概念定义的情形。本文基于统一的热力学参考系,提出标态下复杂燃料焓和[火用]的估算模型;筛选燃料代表物,计算其标准焓和标准[火用]的理论值;基于低位热值拟合标准焓和标准[火用]的模型参数,并验证模型的可靠性。最后,评价若干复杂燃料的热力学特性,支撑其开发利用。For renewable fuels with complex chemical compositions,such as biomass and municipal waste,it is hardly to calculate their enthalpy and exergy,so estimation models are needed.However,accurately and simultaneously estimation for both these two properties is difficult to realize,and there is even a violation of exergy conception.In this paper,based on the unified thermodynamic reference system,estimation models of complex fuels’enthalpy and exergy in the standard state were proposed.Fuel representatives were selected and their theoretical values of standard enthalpy and exergy were calculated,model parameters of the standard enthalpy and exergy were fitted based on the lower heating value;and the reliability of the models was verified.Finally,the thermodynamic properties of some complex fuels were calculated by the proposed models to support future development and utilization.
