With the background of environmental protection and the reduction of CO2 emissions, high-performance and high-efficiency gas turbine combustors are needed. Particularly, gas turbine combustors (hereafter GT combustors) are required to have the same performance level in both oil-fired and gas-fired operations. Mitsubishi Heavy Industries, Ltd. (MHI) is working on applying CFD analysis to the development of oil fuel nozzles. Additionally, MHI developed a blowdown combustion test rig as a new element test method Even in a short time, combustor screenings in equivalent to actual GT conditions are available with the test rig. Furthermore, MHI has also developed a small fiber fused lens probe and realized the measurement of heat release distribution in an oil-fired combustor.
