C205 背圧蒸気タービンとチェンサイクルを組合せた熱サイクルについての研究

抄録

The authors propose Cheng heat-cycle system combined with a backpressure steam turbine for small-scaled distributed co-generation electric power supply. The heat-cycle characteristics compared with other heatcycle systems and conceptual design of the turbine devices are investigated here. This cycle has higher efficiency than regenerative gas turbine cycle, and simpler system structure than conventional combined cycle containing a condensing steam turbine. It is considered as one of promising small-scaled distributed co-generation electric power supply systems, which require high efficiency and low cost.
