Abstract
The development of "integrated coal gasification combined cycle systems" ensures cost-effective and environmentally-sound options for fulfilling future power generation needs. In our laboratory, we are developing a 150 MW, 1500°C-class gas turbine combustor for IGCC by using an air-blown coal gasifier both to enhance thermal efficiency and to reduce NOx emission from the plant. This paper descrides the design of the 150MW, 1500°C-class gas turbine combustor, at atmospheric pressure for IGCC based on the stable and low-NOx combustion technology developed to date. Combustion tests are conducted and the performance of this combustor is evaluated. Test results confirm the excellent performance of the combustor for use in a gas turbine in IGCC and project bright prospects as a high temperature, low NOx combustion technology of the low calorific fuel.
