Abstract
A catalytic combustor (1) is provided for combustion of gaseous and liquid fuels, which combustor comprises a housing (2) having an inlet (3) and an outlet (4) through which an airflow is directed, and a fuel injector (10) for injecting fuel in the airflow. The combustor also comprises at least one catalytic element (12, 14, 15) for combusting the mixture of air and fuel. A fuel-evaporating device (7) is arranged for evaporating a liquid fuel, which device is heated by the catalytic element (12), either through combustion therein or by means of an electrical heating element (13) arranged adjacent thereto.
Claims18
A catalytic combustor for liquid and gaseous fuels comprising a housing having an inlet and an outlet through which an airflow is directed, a fuel injector injecting fuel in said airflow, at least one catalytic element having a support and a catalytically active surface, and a fuel-evaporating device wherein an electrical heating element is provided for simultaneously heating the fuel-evaporating device and the at least one catalytic element, wherein the housing is formed with an expanding portion having a first and second transition and an outlet from the fuel-evaporating device is located in close vicinity to the first transition of the expanding portion of the housing.
