A cogeneration technology in which additional electricity is produced sequentially from otherwise lost waste heat exiting from one or more 气体-fired turbines. The exiting heat flow is routed to an exhaust-fired conventional boiler or to a heat recovery 蒸汽 generator for utilization by a 蒸汽 turbine in the production of electricity. This process increases the efficiency of an electric generating system by turning the rejected heat into thermal 蒸汽 rather than discharging it into the atmosphere.
