许多建筑需要同时用电、供暖和制冷。生物质是一种非间歇性、非位置依赖性、存储难度大的可再生能源。如果可持续生长，生物质可以被认为是二氧化碳中性的。由内燃机和生物质气化相结合的热电联产系统可以提供清洁、经济的供热、发电和制冷的组合。气化炉产生的发生炉煤气通过内燃机为建筑物提供电力。废热从发动机冷却系统和废气中回收，为空间供暖提供热水，多余的热量也被用来驱动吸收冷却系统。拟议的系统旨在满足特定商业建筑和区域供暖/制冷应用的能源需求。本文主要对一座商用建筑规模的生物质下吸式气化炉热电厂进行了建模和仿真。为了最有效地利用能源和财政资源，利用ECLIPSE流程模拟程序包进行了技术和经济分析。这项研究还考察了不同的生物质原料(柳树、稻壳和芒果)对三联产工厂性能的影响。
Many buildings require simultaneous electricity, heating and cooling. Biomass is one of the renewable energy sources which is not intermittent, location-dependent or very difficult to store. If grown sustainably, biomass can be considered to be CO2neutral. A trigeneration system consisting of an internal combustion (IC) engine integrated with biomass gasification may offer a combination for delivering heat, electricity and cooling cleanly and economically. The producer gas generated by the gasifier is used to provide electricity for building use via the IC engine. The waste heat is recovered from the engine cooling system and exhaust gases to supply hot water to space heating, excess heat is also used to drive an absorption cooling system. The proposed system is designed to meet the energy requirements for selected commercial buildings and district heating/cooling applications. This work focuses on the modeling and simulation of a commercial building scale trigeneration plant fuelled by a biomass downdraft gasifier. In order to use both energy and financial resources most efficiently, technical and economic analyses were carried out, using the ECLIPSE process simulation package. The study also looks at the impact of different biomass feedstock (willow, rice husk and miscanthus) on the performance of a trigeneration plant.
