Duct burners are important to Gas Turbine Combined Cycle (GTCC) power units, or smaller Combined Heat and Power (CHP) units, where supplementary firing is of interest. These burners are constructed of multiple rows of bluff body flame holders and fuel injectors. Given the identical nature of each row, segments of duct burners can be adequately simulated in small scale facilities. Altex has available a 500,000 Btu/hr (147 kilowatts) scale duct burner test facility, which can simulate the GTCC or CHP gas turbine exhaust, which is utilized as the oxidizer for the duct burner. Up to two gaseous fuel flows and four air flows can be fed to the duct burner, and independently controlled. This facility, illustrated on this page, is equipped with computer controlled temperature, flow and emissions monitoring systems. Downstream of the duct burner is a confining duct, expanding to a large furnace volume, to simulate the Heat Recovery Steam Generator (HRSG).
