Abstract
This invention relates to the use of a catalytic preburner for heating the pair from compressor discharge temperatures to above the light-off or extinction temperatures of a catalytic combustor. Such structures of this type, generally, eliminate the diffusion flame during steady-state operation and produce a preburner/catalytic combustor system capable of achieving less than 1 ppm NO.sub.x.
Claims2
A catalytic combustor comprising:
- a housing having a main fuel inlet and an air inlet;
- a preburner disposed in said housing at one end thereof, said preburner having a catalyst disposed therein and a preburner fuel inlet;
- a catalytic reactor disposed in said housing, downstream of said preburner;
- and
- means for diverting a small portion of the air from said air inlet into said preburner, and for diverting a major portion of said air from said air inlet into a space between said housing and said preburner then into a section of said housing downstream of said preburner and upstream of said catalytic reactor, said main fuel inlet being located between said preburner and said catalytic reactor.
