چکیده
Abstract With the process of industrialization, a lot energy is consumed, and low-grade produced in process. To recover low grade heat from flue gas coal-fired power plants, organic Rankine cycle built improves utilization efficiency. Taking six working fluids, R245ca, R245fa, R123, R600, R601, R600a, as an example, referring to exhaust condition 300MW subcritical unit, analysed evaporation temperature on net work thermal efficiency exergy efficiency, influence electricity production cost (EPC) payback period (PBP). The results show that R123 largest with same conditions, which system performance. At 400K objective reaping economic benefit, R245ca R601 equivalent values are able be used engineering.
