Development of Gas Turbine Combustors for Low BTU Gas

Abstract

Large-capacity combined cycles with high-temperature gas turbines burning petroleum fuel or LNG have already been operated in large numbers in both domestic and foreign countries and have achieved good results. On the other hand, as the power generation technology utilizing coal burning the coal gasification combined plants are also under research. Since coal-gasified gas is lower in BTU and harder to burn than conventional fuel, development of this combustor is one of the important problems to be solved. To develop the combustor burning low BTU gas in our company, we have proceeded the study for blast furnace gas, i.e. by-product gas in the ironworks and have succeeded in practical use of the multi-can type combustor burning low BTU gas in the combined plant supplied to Chiba Works, Kawasaki Steel Corporation.
