Abstract
Disclosed is a hybrid high pressure catalytic combustion burner employing catalysts and CST combustion with staged mixing systems, in which a primary combustion gas containing reacted gas of a primary gas mixture, which is formed via catalytic combustion, is subject to a secondary mixing with the primary gas mixture containing fuel and high temperature air, completing stable high temperature CST combustion at ultra lean conditions, thereby achieving high temperature combustion reducing formation of NOx.
Claims9
A hybrid high pressure catalytic combustion burner with staged mixing systems employing catalysts and CST combustion, comprising:
- a primary gas mixing portion for homogenous mixing of preheated air with fuel;
- a catalytic combustion portion for combusting the gas mixture prepared in the primary gas mixing portion via surface reaction;
- a secondary gas mixing portion for mixing of reacted gas via surface reaction in the catalytic combustion portion with unreacted gas which is not subject to surface reaction;
- and
- a CST combustion portion for burning the gas mixture prepared in the secondary gas mixing portion.
