CATALYTIC COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To make it possible to allow the activity and durability of a catalyst to be compatible in the catalytic combustor for a gas turbine. SOLUTION: A catalyst is divided into a catalytic part 3a for low temperature and a catalytic part 3b for high temperature. Mixers 2a are provided at the upstream side to premix fuel and the air or fuel and partial combustion gas. Thus, the part 3a having no heat resistance but excellent low temperature activity is used at the low temperature part, and the part 3b having lack of low temperature activity but excellent heat resistance is used at the high temperature part.
