KAWASAKI REFINES ITS DLE COMBUSTION SYSTEM: A NEW COMBUSTOR REDUCES NO_x BELOW 10 PPM IN AN 8 MW, M7A-O3 GAS TURBINE

摘要

Kawasaki Heavy Industries (KHI) introduced its first industrial gas turbine in 1974 for stand-by use sets, followed by a baseload gas turbine in 1984. Since then, the company has delivered more than 10,000 GTs in the 0.2 to 18 MW range. In keeping with regulatory requirements, KHI released a Dry Low Emissions (DLE) combustion system in 2009, which guaranteed <15 ppm NO_x (O~2 = 15%) for the 8 MW Kawasaki M7A-03 and the 18 MW Kawasaki L20A. Most recently, the company developed a single-digit NO_x Dry Low Emissions (DLE) combustor for the M7A-03 turbine. It achieves <9 ppm NO_x and <25ppm CO emissions. Specifications and general layout of the M7A-03 are shown in Table 1 and Figure 1, respectively.
