ABSTRACT:
A miniature flat spray nozzle is disclosed which delivers a fan-shaped mist of fuel to a gas turbine combustor from a narrow slot. The slot is formed by making a transverse cut in a fuel-carrying conduit at a location near its end. A specially formed part is inserted into the end of the conduit which, in addition to capping off the conduit, divides the space adjacent thereto into three small chambers. One chamber is immediately below the transverse slot. Four orifices in the bottom wall of this first chamber connect it with the other two chambers. Each of the lower chambers opens into the conduit at its upstream end. Fuel delivered down the conduit divides in two parts, passes through the orifices between the lower and upper chambers, undergoes turbulent mixing in the chamber adjacent the transverse slot, and issues forth from the slot as an atomized mist.
