Combustion system incorporating temperature swing adsorptive gas separation

A combustion system comprising:

• an oxidant preheater fluidly connected to a primary oxidant source and to a secondary oxidant source and operable to provide a preheated primary oxidant stream and a preheated secondary oxidant stream;
• a fuel source;
• a combustor, fluidly connected to recover at least one of said preheated primary oxidant stream and said preheated secondary oxidant stream from said oxidant preheater, and a fuel stream from said fuel source for combustion, to produce a combustion gas stream, and fluidly connected to admit said combustion gas stream into said oxidant preheater;
• a feedwater source;
• an integrated heat exchanger having a hot side fluidly connected to said combustor and a cold side fluidly connected to recover at least one of a water and/or a condensate stream from said feedwater source, to produce a high pressure steam stream from said cold side;
• a particulate collector fluidly connected to recover said combustion gas stream from said oxidant preheater, for forming a first treated combustion gas stream;
• a direct contact cooler fluidly connected to recover a first portion of said first treated combustion gas stream from said particulate collector;
• a temperature swing adsorptive gas separator fluidly connected to recover said first portion of said treated combustion gas stream from said direct contact cooler as a feed stream comprising at least a first component, fluidly connected to recover a steam stream from at least one of a turbine or a boiler as a first regeneration stream, fluidly connected to recover a second portion of said first treated combustion gas stream from said particulate collector as a second regeneration stream, and fluidly connected to release a first product stream into an ambient environment, wherein said temperature swing adsorptive gas separator is operable to separate at least a portion of said first component from said feed stream to produce a second product stream;
• a condenser fluidly connected to recover said second product stream from said temperature swing adsorptive gas separator to form said condensate stream and a purified second product stream;
• an ejector having a low pressure port and a high pressure port, said low pressure port fluidly connected to admit said purified second product stream recovered from said condenser;
• and
• a compressor for producing a compressed second product stream, fluidly connected to receive said purified second product stream from said ejector and fluidly connected to admit said compressed second product stream into said high pressure port of said ejector.
