Title:
WASTE HEAT-FED HEAT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/066964
Kind Code:
A3
Abstract:
The invention describes a heat recovery system (WNV), which in a working fluid (BM) circulation achieves a high overall efficiency of from 0.45 <ŋPM+WNV < 0.69 utilising the cooling heat and/or the exhaust gas heat of a primary engine (PM). A combustion engine (I, VM2), stationary or installed in a vehicle, particularly a motor vehicle, a gas/steam turbine power plant (II, GT4, DT3,3'), a combined heat and power station or a burner (III, BR9), particularly a biogas burner, are used as the primary engine. A superheated steam or a mixture of a supercritical high-pressure steam plus the superheated steam and/or plus portions of the exhaust gas are used as the working fluid producing enthalpy of mixing. The invention further relates to a use of the heat recovery system as an air or exhaust gas compressor with storage, as a mechanical supercharger of the primary engine, which, like the heat recovery system, can be operated as a compressed air/exhaust gas engine or as a booster using the stored compressed air/compressed exhaust gas (53). A relative overall efficiency of the combined PM + WNV plant of 1.6 < PPM
+
WNV/PPM < 2.3 is achieved.
