随着分布式发电的日益受到重视，在 21 世纪的第一个十年，将需要一个能够满足各个家庭总能源需求的紧凑型热能系统。超低排放的天然气燃料热电联产微型涡轮机将满足这一需求。本文介绍了评估 25 至 5 Kwe 范围内微型涡轮机的热力和经济方面的研究结果。经确定，采用当前最先进的组件峰值性能水平和金属材料，在海平面标准日条件下可分别实现 27% 和 22.5% 的热效率目标。微型涡轮机与燃料电池组合可实现高达 60% 的总热效率，与废气锅炉组合可实现接近 80% 的总热效率。低成本天然气燃烧器喷射方法的开发与低成本高效换热器相结合被认为是市场接受的强制性要求。版权所有 © 2000 by ASME
In concert with the growing emphasis placed on distributed power generation there will be a need, in the first decade of the 21st century, for a compact thermal energy system capable of providing the total energy needs of individual homes. A natural gas fueled cogeneration microturbine with ultra low emissions will meet this need.The results of a study to assess the thermal and economic aspects of microturbines in the 25 to 5 Kwe range are presented. It was determined that with current state of art component peak performance levels, and metallic materials, thermal efficiency goals of 27 and 22.5% respectively at sea level standard day conditions are attainable. Higher overall thermal efficiencies of 60% are attainable with a microturbine combined with a fuel cell, and approaching 80% combined with exhaust fired boilers.Development of a low cost natural gas combustor injection method, combined with a low cost high effectiveness recuperator were considered mandatory for market acceptance.Copyright © 2000 by ASME
