Industry Waste Pressure Power Generation
Industry waste pressure mainly include high-pressure process gas and saturated or superheat steam with pressure in steel and chemical factory. Currently, these gas or steam pressure is decreased to required value through pressure reducing value, which waste pressure energy. Kaishan direct expansion screw power generation unit can recover the pressure energy and convert it to electricity energy through a generator, which can bring good benefit for customer.
Direct expansion power generation unit can be divided into back pressure type unit and condensing type unit. Asynchronous or synchronous generator is used for power output. It can be divided into steam type unit or gas type unit according to working medium.
Industry waste heat accounts for 17% - 67% of fuel consumption, but only 60% of the total waste heat resource can be recovered. Kaishan ORC screw expander power plant is suitable to recover industry waste heat directly or indirectly e.g. hot water, hot oil, steam, engine jacket water/exhausted gas and gas-turbine exhausted gas, and finally convert into electricity. According to heat resource gather mode, Kaishan ORC screw expander power plant is categorized as direct recovery ORC unit and indirect recovery ORC unit. It can also be categorized as hot water ORC, steam ORC and other ORC according to different waste heat resource type.
