SEQUENTIAL COMBUSTION FIRING SYSTEM FOR A FUEL SYSTEM OF A GAS TURBINE ENGINE

摘要

A gas turbine combustion system (10) for a turbine engine (12) is disclosed. The gas turbine combustion system (10) may include a plurality of combustor baskets (14) positioned circumferentially about a longitudinal axis of the turbine engine (12), at least one firing nozzle (18) extending into each of the plurality of combustor baskets (14) and a fuel delivery system (20) in communication with each of the at least one firing nozzles (18) and in communication with at least one fuel source. Each combustor basket (14) may include a fuel flow control device (24) of the fuel delivery system (20) inline with each of the at least one firing nozzles (18) in that combustor basket (14) such that fuel flow to some of the combustor baskets (14) can be shut off while fuel flow to firing nozzles (18) in other combustor baskets (14) remains unobstructed, thereby permitting some combustor baskets (14) to remain non- fired while other combustor baskets (14) are firing to reduce CO emissions.
