WZ-5 engine is a small aero gas turbine engine rated in 1200kw class. A development program was initiated in 1986 to develop the engine with some modifications to accommodate the medium or low Btu gaseous fuel for its industrial application. The test program was accordingly carried out for the modified engine and combustor to evaluate their ability to burn medium Btu gaseous fuel. The present investigation is a part of the program to justify whether or not the modified combustor is capable of burning the medium Btu gaseous fuel with satisfactory combustion performances. The medium Btu gaseous fuel used in the test contains 50% of H2 and 20% of CH4 and the rest of N2 as innert. That is the typical processing gas produced in chemical fertilizer production. The low heating value of the gas is 3002 kcal/nm3.

All the test results whowed that when burning the medium Btu gaseous fuel the modified combustor had quite good performances except one combustor which had the injectors with slot-shape opening at the injector end and had unacceptable combustor exit temperature profile, and also showed that the modified combustor had the potential ability to burn low Btu gaseous fuel which has lower calorific value but some amount of H2.
