Abstract:
A cogeneration system comprising;a fuel-burning turbine having a first output drive shaft and producing heated exhaust gases; a first working machine coupled to said output drive shaft for producing electrical energy; a hot-liquid heat-exchanger using a high-temperature-resistant liquid heat transfer fluid to absorb heat from said exhaust gases produced by said fueled turbine, a heat utilization device connected to receive heated heat transfer fluid from said heat-exchanger and extract heat from said fluid, a closed-circuit conduit for conveying said heat transfer fluid from said heat-exchanger, past said heat utilization device and back to said heat-exchanger, means in said closed circuit for flowing said heat transfer fluid through said closed-circuit conduit, and an absorption chiller having a generator section in heat-transfer connection with said conduit at a location downstream from said heat utilization device to utilize heat from said heat transfer fluid to produce cooling.
