Abstract
A catalytic combustor ( ) for a gas turbine engine ( ). A fuel-air mixture ( ) is reacted on a catalytic surface ( ) of a catalytic heat exchanger module ( ) to partially combust the fuel ( ) to form heat energy. The fuel-air mixture is formed using compressed air ( ) that has been pre-heated to above a reaction-initiation temperature in a non-catalytic cooling passage ( ) of the catalytic heat exchanger module ( ). Because the non-catalytic cooling passages ( ) provide the necessary pre-heating of the combustion air, no separate pre-heat burner is required. Fuel ( ) is added to the pre-heated air ( ) downstream of the non-catalytic cooling passage ( ) and upstream of the catalytic surface ( ), thereby eliminating the possibility of flashback of flame into the cooling passages ( ). Both can-type ( ) and annular ( ) combustors utilizing such a combustion system are described.
