Combustion systems which employ such features as rotary cup fuel atomizers and the latter in conjunction with CIVIC combustion to enhance flame performance, to produce efficient combustion over a wide operating range, and to eliminate the problems typically encountered in liquid fueled combustors, especially as they are scaled down in size. Innovations that can advantageously be employed in combustors operated on other fuels are also disclosed.

A method of effecting the stable, nonluminous combustion of a liquid fuel which comprises the steps of: generating an annulus of axially moving, rotating combustion air; forming the liquid fuel being burned into a thin, uniform, annular, stratified, atomized film of fuel on the inner boundary of said combustion air annulus at a specified location therealong; vaporizing said atomized fuel while it remains in said stratified film; and thereafter rapidly expanding said annuli of combustion air and vaporized fuel and then so effecting a downstream contraction of the fuel-air mass by way of a mechanical or aerodynamic constraint as to promote the mixing and subsequent combustion of said vaporized fuel and air and the formation of a recirculation zone containing hot gases which stabilize the flame generated by the combustion of the fuel and air and effect said vaporizing of the stratified atomized fuel and the heating of the vaporized fuel before said vaporized fuel is mixed with the combustion air.
