ABSTRACT:
In a combustion method, in a burner (12, 20), a fuel/air mixture flowing through a flow passage (13) is made to react in a first combustion stage in a catalytic reactor (15), and downstream of the catalytic reactor (15) fuel is burnt together with the exhaust gas from the catalytic reactor (15) in a second combustion stage to form a homogenous flame (17) by self-ignition.If the fuel from the fuel/air mixture is only partially burnt in the first combustion stage in the catalytic reactor (15), and the unburnt remainder of the fuel is burnt in the second combustion stage, combustion can be stabilized by virtue of the fact that the fuel-containing exhaust gas from the catalytic reactor (15), between the outlet of the catalytic reactor (15) and the homogenous flame (17) is passed through devices916, 19) which aerodynamically stabilize the homogenous flame (17).
