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.

A heating device (100) for combustion of liquid fuels comprises at least one catalytic element (140) for catalytically burning a mixture of fuel and air, a fuel supply means (133) being disposed on an upstream side of said first catalytic element (140) and an air supply means (132) being disposed on an upstream side of said at least one catalytic element (140). A fuel-evaporating device (130) has a substantially axisymmetric shape and an upstream end and a downstream end. The fuel-evaporating device is heated, during operation, by the at least one catalytic element (140), and is supplied with fuel and air from the fuel supply means (133) and the air supply means (132). The heating device also comprises an outer housing (110), for containing said catalytic element (140) and said fuel-evaporating device (130). The fuel -evaporating device (130) is provided with at least one inner inlet pipe (132; 132b) in the generally upstream end thereof. The pipe (132; 132b) is arranged to inject fuel and/or air in a tangential direction into the generally upstream part of the fuel -evaporating device (130) such that a rotational flow is obtained therein. Moreover, the generally upstream end of the fuel- evaporating device (130) is arranged in the vicinity of the at least one catalytic element (140),
