The Analysis on the Scheme of the Flue Gas Compressor of a 300 MW Oxy-Fuel Pulverized Coal Fired Boiler

Abstract:

The compression of the flue gas is one of the most critical processes of CO2 recycling in oxy-fuel combustion technology. With a 300 MW Oxy-fuel pulverized coal fired boiler taken as an example of study, the selection of compressors of its flue gas compressing system is analyzed by the thermodynamic calculation. In this paper, two centrifugal compressors with the same specification are in parallel running as Scheme 1 of selection, while an axial compressor and a piston compressor are in series operation as Scheme 2 of selection. It shows that the Scheme 2 has the advantage of the energy consumption and water separation of the flue gas in inter-cooler comparing with Scheme1.
