Catalytic combustion system with multistage fuel injection

摘要

The present invention relates to a catalytic combustion system comprising a casing (1) having an inlet (2) for an oxidizer such as air, several fuel injection means (3, 5; 7) intended for a multistage fuel injection, and at least a first monolithic element (4) that may be covered with a combustion catalyst and situated downstream from a first fuel injection means (3) in relation to the direction of progress of an air-fuel mixture in the system, said first injection means performing a partial fuel injection, and comprising at least a second monolithic element (6) situated downstream from a second injection means (5), said second monolithic element (6) being intended to stabilize the combustion. The second monolithic element (6) can be covered with a combustion catalyst.
