Open feedwater heater three inlet thermo
WebBased on the structural theory of thermo-economics, a 600 MW unit was taken as an example. An integration system which uses fuel gas heat and solar energy as a heat source for post-combustion carbon capture was proposed. The physical structure sketch and productive structure sketch were drawn and a thermo-economics model and cost model … Web24 de fev. de 2012 · In-direct mixing feed water and steam in a shell and tube type heat exchanger. Pump is required to transfer the water into next stage in the cycle. Closed feed water pumps don’t require pump and can operate with the pressure difference between the various heaters in the cycle. Requires more area. Requires less area.
