摘要： A unique and useful dynamic control system for the control of a catalytic combustion system for use on a dynamic plant, preferably, a gas turbine engine (14). The dynamic control system facilitates the replacement of conventional flame combustion systems with catalytic combustion systems. A method of controlling the catalytic combustion process comprises the steps of calculating a mass flow of air introduced into the combustor, monitoring a flow of fuel to be combusted within the combustor (32), monitoring a temperature of the air introduced into the combustor (32), calculating an inlet temperature set point based on the mass flow and fuel flow, and controlling a pre-burner (54) to heat the air based on the inlet temperature set point, the mass flow, and the temperature of the air. Further, the mass flow may be estimated based on ambient air temperature and pressure, and compressor (20) speed. A catalytic combustion gas turbine system is also presented, the operation of which is controlled by a dynamic plant controller (34) which generates a fuel flow rate demand signal to control the flow of fuel to be combusted in response to dynamic plant demands.

摘要： A gas turbine engine combustion chamber (28) comprises a primary combustion zone (36) and a secondary combustion zone (40) downstream of the primary combustion zone (36). A catalytic combustion zone (44) is arranged downstream of the secondary combustion zone (40) and a homogeneous combustion zone (100) is arranged downstream of the catalytic combustion zone (44). A pilot injector (62) supplies fuel into the primary combustion zone (36). At least one primary premixing duct (54,56) has a plurality of primary fuel injectors (58,60) to supply a first mixture of fuel and air into the primary combustion zone (36). A secondary premixing duct (64) has a plurality of secondary fuel injectors (82) to supply a second mixture of fuel and air into the secondary combustion zone (40). A plurality of temperature sensors (102) are arranged at the intake to the catalytic combustion zone (44) and a processor (104) controls the valves (106,108,110) which adjust the supply of fuel the fuel injectors (58,60,62,82) to ensure that the temperature at the intake to the catalytic combustion zone (44) remains in a predetermined temperature range.
