Abstract
A carbon sequestration system includes a furnace having an oxy-combustion burner, a mill configured to receive a fuel and to provide the fuel to the oxy-combustion burner, a waste heat recovery exchanger configured to receive a flue gas from the furnace, the flue gas ultimately supplied to one or more of an overfire air port of the furnace, the oxy-combustion burner, the mill, and a CO2 purification unit, the CO2 purification unit configured to produce a purified CO2 stream.
Claims20
A carbon sequestration system, comprising:
- a furnace having an oxy-combustion burner;
- a mill configured to receive a fuel and to provide the fuel to the oxy-combustion burner;
- a waste heat recovery exchanger configured to receive a flue gas from the furnace;
- an electrostatic precipitator configured to receive the flue gas from the waste heat recovery exchanger;
- a direct contact cooler/polishing scrubber configured to receive the flue gas downstream of the waste heat recovery exchanger and to exhaust the flue gas as a cooled flue gas;
- a first cooled flue gas recycle supply stream configured to supply the cooled flue gas to
- a first flue gas recycle supply stream, the first flue gas recycle supply stream configured for input to a flue gas recycle heater and for output from the flue gas recycle heater as a heated flue gas recycle supply stream configured for input to at least one of an overfire air port of the furnace or the oxy-combustion burner as a secondary flue gas recycle stream, and
- a second flue gas recycle supply stream, the second flue gas recycle supply stream configured for input to the mill;
- and
- a second cooled flue gas recycle supply stream configured to supply the cooled flue gas to a CO2 purification unit, the CO2 purification unit configured to produce a purified CO2 stream from the second cooled flue gas recycle stream for sequestration.
A method for generating purified carbon dioxide for sequestration using a system comprising a furnace having an oxy-combustion burner, a mill configured to receive a fuel and to provide the fuel to the oxy-combustion burner, a waste heat recovery exchanger configured to receive a flue gas from the furnace, an electrostatic precipitator configured to receive the flue gas from the waste heat recovery exchanger, and a direct contact cooler/polishing scrubber configured to receive the flue gas downstream of the waste heat recovery exchanger and to exhaust the flue gas as a cooled flue gas, the method comprising:
- supplying the cooled flue gas via a first cooled flue gas recycle supply stream to
- a first flue gas recycle supply stream, the first flue gas recycle supply stream configured to for input to a flue gas recycle heater and for output from the flue gas recycle heater as a heated flue gas recycle supply stream configured for input to at least one of an overfire air port of the furnace or the oxy-combustion burner as a secondary flue gas recycle stream, and
- a second flue gas recycle supply stream, the second flue gas recycle supply stream configured for input to the mill;
- and
- supplying the cooled flue gas via a second cooled flue gas recycle supply stream to a CO2 purification unit, the CO2 purification unit configured to produce a purified CO2 stream from the second cooled flue gas recycle stream for sequestration.
