Staged combustor

摘要

A staged combustor including a first combustion stage for combusting a fuel rich mixture of a fuel and an oxidizer. A plurality of serially positioned secondary combustion stages, downstream the first stage, are provided for receiving secondary flows of oxidizer to the increasing mass of combustion efflux. The gradual increase of oxidizer/fuel ratios provide a resultant substantially stoichiometric combustion. A cooling system is provided for cooling these combustion stages.
