The present invention is directed to a lean direct injection (LDI) combustion system for a gas turbine using a shell and tube heat exchanger concept to construct a shell and tube lean direct injector (“LDI”) for the combustion system. One side of the LDI injector, either the shell side or the tube side, carries an oxidizer, such as air, to the combustor, while the other side of the LDI injector carries fuel to the combustor. Straight or angled holes drilled in an end plate of the combustor allow the fuel to enter the combustor and mix with air being injected into the combustor.

What is claimed is: 1. A combustion system comprising:a combustor for burning a mixture of air and fuel, the combustor comprising an end plate, anda lean direct injector for directly injecting fuel and air into the combustor, the injector comprising:a shell including an inlet through which air or fuel is introduced into the shell, the shell having one end connected to the combustor so that air or fuel from the shell passes directly into the combustor end plate for direct injection into the combustor, anda plurality of tubes positioned inside the shell and extending to the combustor so that fuel or air from the plurality of tubes passes directly into the combustor end plate for direct injection into the combustor,the combustor end plate including a first plurality of holes for injecting air or fuel from the shell directly into the combustor, and a second plurality of holes for injecting fuel or air from the plurality of tubes directly into the combustor.
