← Previous | Next →

Parameters related to the flue gas recycle system are entered on the FG Recycle parameter screen. The following parameters are available:

•Flue Gas Recycle Stream:

•Flue Gas Recycled: This is the percentage of the total flue gas that is to be recycled.

•Maximum Recycle Moisture: This is the maximum amount of moisture in combined recycle.

•Particulate Removal Efficiency: This is the percentage of particulates that are removed by the Flue Gas Recycle system.

•Flue Gas Cooling Power Requirement: This is the percentage of the total gross power of the plant required to cool the flue gas being recycled.

•DCCPS Exit Temperature: This is the temperature of the gas streams exiting the direct contact cooler and polishing systems.

•Recycle Fan Pressure Head: A fan is used to provide a small pressure head for the recycled flue gas stream going back to the boiler. This FGR fan pressure head along with the recycled flue gas flow rate, determine the power used by the fan.

•Recycle Fan Efficiency: This is the efficiency of the fan converting electrical power input into mechanical work output.

•Flue Gas Recycle Power Requirement: This is the percentage of the total gross power of the plant required to recycle the flue gas.

•FGR Cool. Duty Recov. as Heat Integration: This is the fraction of cooling duty recovered as heat integration.

•Maximum DCC Train Capacity: This is the maximum capacity of a direct contact cooler train.

•Number of DCC Trains: This is the number of trains in the direct contact cooler.

•Pressure Drop Across DCC: This is the pressure drop on gas going through the direct contact cooler.
