OXY-FUEL EXPANDER SYSTEM INCLUDING MULTIPLE HEAT EXCHANGERS AND METHOD

The oxy-fuel expander system (1) comprises a combustor (3) and an expander fluidly coupled to the combustor and rotated by expansion of the pressurized hot combustion gas from the combustor. A high-temperature heat exchanger (22) and a low-temperature heat exchanger (21) are arranged to recover heat...

More Information
Summary:The oxy-fuel expander system (1) comprises a combustor (3) and an expander fluidly coupled to the combustor and rotated by expansion of the pressurized hot combustion gas from the combustor. A high-temperature heat exchanger (22) and a low-temperature heat exchanger (21) are arranged to recover heat from the combustion gas and heat an oxidant stream and a stream of combustion gas recycled towards the combustor and the expander (5). Le système détendeur d'oxy-combustible (1) comprend une chambre de combustion (3) et un détendeur couplé de manière fluidique à la chambre de combustion et mis en rotation par expansion du gaz de combustion chaud sous pression provenant de la chambre de combustion. Un échangeur de chaleur à haute température (22) et un échangeur de chaleur à basse température (21) sont conçus pour récupérer la chaleur provenant du gaz de combustion et chauffer un flux d'oxydant et un flux de gaz de combustion recyclé vers la chambre de combustion et le détendeur (5).
