Abstract
A fuel atomizer using a spray plate, for a highly spun liquid fuel is described for generating spaced apart fuel rich zones separated by a fuel lean zone by forming a slot in an outer domed surface of the spray plate. The shape of the domed surface is selected so that the spinning fuel, which is also under a high pressure, is permitted to preferentially expand in the direction of the ends of the slot while increasingly spilling over a wall bounding the slot. With a fuel atomizer in accordance with the invention substantial reductions in the generation of thermal NOx can be achieved in boilers when the fuel atomizer is placed within a flame stabilizer.
