Methods for operating catalytic combustion chambers including first and second catalytic reactors disposed in series with an intermediate chamber therebetween are disclosed, the method including heating the first catalytic reactor to a temperature at least equal to the ignition temperature of the first catalytic reactor, introducing air and fuel mixture to the first catalytic reactor whereby catalytic combustion is initiated in the first catalytic reactor, and increasing the mass flow through the first catalytic reactor whereby combustion of the air and fuel mixture takes place in the gas phase in the intermediate chamber and the end surface of the second catalytic reactor is heated to a temperature at least equal to the ignition temperature of the second catalytic reactor and ignition takes place in the second catalytic reactor.
A method of operating a catalytic combustion chamber including a first catalytic reactor, a second catalytic reactor including an end surface facing said first catalytic reactor, said second catalytic reactor disposed in series with said first catalytic reactor, and an intermediate chamber between said first and second catalytic reactors, said method comprising heating the first catalytic reactor to a temperature at least equal to the ignition temperature of said first catalytic reactor, introducing an air and fuel mixture to said first catalytic reactor, whereby catalytic combustion is initiated in said first catalytic reactor, and increasing the mass flow of at least said air through said first catalytic reactor whereby combustion of said air and fuel mixture takes place in the gas phase in said intermediate chamber and said end surface is heated to a temperature at least equal to the ignition temperature of said second catalytic reactor and ignition takes place in said second catalytic reactor.
