A low emissions combustion system for a gas turbine engine, including a generally annular combustor with a plurality of tangential fuel injectors to introduce a fuel/air mixture. The annular combustor includes a skirt shaped flow control baffle from the inner liner and air dilution holes in the inner liner underneath the flow control baffle and also in the cylindrical outer liner. The fuel injectors extend through the recuperator housing and into the combustor through an angled tube and then through a tangential guide in the cylindrical outer liner of the combustor housing. The fuel injectors generally comprise an elongated injector tube with the outer end including a coupler having at least one fuel inlet tube. Compressed combustion air is provided to the interior of the elongated injector tube from either holes or slits therein which receive compressed air from the angled tube around the fuel injector which is open to the space between the recuperator housing and the combustor.
