Abstract:
A combustion system for a hybrid solar receiver, comprising:a pre-mixer having a first inlet for air and a second inlet for fuel, said pre-mixer combining the air and the fuel to form an air-fuel mixture; a cooling jacket open to said pre-mixer on one end, the air-fuel mixture introduced tangentially into said cooling jacket; a burner plenum fluidically connected to said cooling jacket, said burner plenum and said cooling jacket arranged in thermal contact with one another with the air-fuel mixture flowing through said cooling jacket cooling said burner plenum to reduce pre-ignition of the air-fuel mixture in said burner plenum; a combustion chamber open to said burner plenum, said combustion chamber receiving the air-fuel mixture from said burner plenum; an igniter positioned in said combustion chamber, said igniter combusting the air-fuel mixture, the combustion of the air-fuel mixture releasing heat; a recuperator operatively associated with said burner plenum and said combustion chamber, said recuperator pre-heating said air-fuel mixture in said burner plenum with heat from said combustion chamber; and a heat-exchanger in thermal contact with said combustion chamber, said heat-exchanger providing heat for the hybrid solar receiver.
