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 R123. While this novel ORC can not only improves the energy utilization, but also be suitable for some occasions without power.
Key words:    gas-liquid injector    organic fluid    pump    energy utilization
