In the current paper, under condition of different flue gas temperatures and constant thermal power, influence organic working fluids on efficiency sub-critical Rankine cycle system were studied. The other parameters simple calculated. results show that could reach maximum when in expander inlet are dry-saturation. Flammability, toxicity, ozone depletion factors should be considered cycles. R245fa is a better choice for low-temperature heat source power generation, about 10.2%; high-temperature source, R601a can considered; however, due to its high flammability, novel further discovered generation.
