ABSTRACT:
New combustors which produce lower emissions, particularly lower emissions of nitrogen oxides and CO, are provided. The combustors are provided with a first combustion region that is cylindrical, short and of small diameter and an adjacent downstream second combustion region comprising an abrupt enlargement in diameter to provide a relatively larger capacity than the first combustion region. A first stream of air is introduced, either radially, axially, or tangentially, into the first combustion region and the amount of said air is varied in accordance with fuel flow to the first combustion region. A second stream of air is introduced tangentially into the first combustion region. A third stream of air is introduced tangentially into the second combustion region. In preferred embodiments of the invention the air stream pressure drop across an air assist fuel nozzle is varied in accordance with fuel flow to the nozzle.
