Abstract Combined cooling, heating, and power systems have been studied extensively because of their great potentials. Accordingly, in the present study, an innovative trigeneration system including a gas turbine cycle, a gasification unit, a heating unit, alongside a single effect absorption refrigeration cycle is proposed. The system operates on natural gas and municipal solid waste (MSW) for cooling, heating, and power generation. The designed system was simulated using Engineering Equation Solver (EES) software through two scenarios; constant power output and constant biomass feed rate, considering seasonal and annual periods. In the first scenario, considering the constant power capacity, the basic design state was considered with the biomass mixing ratio of 50%, and the results of the seasonal study showed that the system capacity is 30 MW , 41.9 MW , and 39.24 MW in terms of electricity, heating, and cooling, respectively. The exergy analysis revealed that the combustion chamber, the evaporator of Heat Recovery Steam Generator (HRSG), and the gasifier in both hot and cold seasons have the highest exergy destruction rate, while the economizers and the evaporators of both HRSGs have the lowest exergy efficiency. The constant mass flow rate of MSW was assumed to be 1.5 kg / s and accordingly, the feed rate of natural gas was also 1.5 kg / s for the mixing ratio of 50% in basic design state of the second scenario, and the results indicated that the annual average capacity of the system for electricity, heating, and cooling generation is 27.43 MW , 40 MW , and 34.15 MW , respectively. Furthermore, the system was capable of providing the domestic hot water supply of end-user with an average capacity of 7.5 MW during a year. The annual Energy Utilization Factor (EUF) and the annual exergy efficiency of the overall system were shown to be 71.25% and 30.79%, respectively.

由燃气轮机驱动的新型季节性冷热电联供系统的能量和火用分析，该系统与生物质气化装置和溴化锂吸水冷却器相结合

摘要 冷、热、电联合系统因其巨大的潜力而被广泛研究。因此，在本研究中，提出了一种包括燃气轮机循环、气化单元、加热单元以及单效吸收式制冷循环在内的创新三联产系统。该系统使用天然气和城市固体废物 (MSW) 进行冷却、加热和发电。使用工程方程求解器 (EES) 软件通过两个场景对设计的系统进行仿真；考虑季节性和年度期间，恒定功率输出和恒定生物量进料率。在第一种情景中，考虑恒功率容量，考虑基本设计状态，生物质混合比为50%，季节性研究结果显示系统容量为30 MW，电力、加热和冷却分别为 41.9 MW 和 39.24 MW。火用分析表明，热回收蒸汽发生器 (HRSG) 的燃烧室、蒸发器和冷热季节的气化器的火用破坏率最高，而两种 HRSG 的省煤器和蒸发器的火用效率最低. 假设 MSW 的恒定质量流量为 1.5 kg/s，因此，在第二种情景的基本设计状态下，对于 50% 的混合比，天然气的进料速度也为 1.5 kg/s，结果表明发电、供热、制冷系统年均发电容量分别为27.43 MW、40 MW和34.15 MW。此外，该系统能够为终端用户提供一年平均7.5兆瓦的生活热水供应。整个系统的年度能源利用系数 (EUF) 和年度火用效率分别为 71.25% 和 30.79%。
