Data were gathered to determine the performance of a boiler burner with a gun-type fuel injector when retrofit with three low-Btu gases; the performance of natural gas was used as a base line for comparison. The burner was fired on the IGT pilot-scale test furnace, simulating one burner in a multiburner array of an industrial boiler. The low-Btu fuel gases used for these combustion trials were Koppers-Totzek oxygen (KTO), Wellman-Galusha air (WGA), and Winkler air (WA). In order to fire the low-Btu gases at the 3.0 million Btu/hr rate and upstream pressure of 30 psia used for natural gas, the fuel injector had to be modified. Modifications consisted of increasing the sizes of the fuel orifices, permitting delivery of the required fuel volume at sonic velocity. With the appropriate fuel injector, all the low-Btu fuels exhibited stable flames at fuel enthalpy inputs of 3.0 million Btu/hr. All the low-Btu fuel gases had longer flame lengths than natural gas, although not long enough to create flame impingment problems. The thermal efficiencies of the low-Btu gases ranged from 29.5% for KTO to 26% for WA compared with 32% for natural gas.
