Abstract

A fuel and air mixing apparatus for a combustor and gas turbine generator. A primary portion of the fuel is injected into the mixing air at long distances from the combustor prechamber. The primary portion of the fuel is almost completely mixed with the mixing air. A secondary portion of fuel is injected into the mixing air in the boundary layer at a short distance form the combustor prechamber. This minimally mixed second portion provides some rich portions of fuel-air in the prechamber to improve stability and reduce the chances of blowout.
