Low NO_x hydrogen combustion technology for gas turbine for electricity supply

Abstract

Kawasaki Heavy Industries, LTD. (KHI) has research and development projects for future hydrogen society; production of hydrogen gas, refinement and liquefaction for transportation and storage, and utilization with gas turbine / gas engine for electricity supply. In the developments of hydrogen gas turbine, the key technology is stable and “Low NO_x” hydrogen combustion. This paper describes three types of the Low NO_x hydrogen combustion technology for hydrogen gas turbine. At first, challenges for hydrogen combustion described. In the next chapter, a “Dry type Low NO_x” combustion technology for mixture fuel of hydrogen and natural gas which uses supplemental burner, a “Wet type Low NO_x” pure hydrogen combustion technology which uses water or steam and a “Dry type Low NO_x” pure hydrogen combustion technology are described each.
