Research of Natural Gas Ultra Low Emission Combustor

Article of Honda R&D Technical Review Vol.15 No.2


A homogeneous mixing and autoignition prevention of air and natural gas has been simultaneously obtained adopting a multi-venturi composed with a number of dispersely arranged venturi mixers set up as a premixed lean burn combustor. By applying the characteristics of the venturi mixers, a high accuracy prehension of the state of combustion was enabled, and the enlargement of the premixed combustion range was achieved. The combustor system above was installed on a micro-gas turbine, achieving an ultra low emission level of 3ppm (at 15 percent oxygen equivalent) NOx, CO and THC at 50 to 100 percent load.
