Catalytic preburner and associated methods of operation

摘要

A catalytic preburner includes a flame burner, a catalyst, a primary fuel inlet, a secondary fuel inlet, and an air inlet. The flame burner is located in a primary zone of the housing and the catalyst element is disposed downstream of the primary zone. The primary fuel inlet and the air inlet are configured to supply fuel and air to the flame burner. The secondary fuel inlet and the air inlet are configured to supply fuel and air to a secondary zone within the housing located upstream of the catalyst element.
