The organic Rankine cycle ( ORC ) is an effective way to recycle low temperature exhaust heat but pump for the ORC has several disadvantages such as great difficulty in manufacturing , easily-invited cavitations , low efficiency and high cost .Gas-liquid two-phase injector is a device without moving parts , in which steam is used to drive cold liquid from a pressure lower than the primary steam to a pressure higher than the primary steam.In this paper , the mechanical circulation pump was replaced with a gas-liquid injector .The effect of the evaporate temperature for the system was studied with the organic fluid R 123.While this novel ORC can not only improves the energy utilization , but also be suitable for some occasions without power .
