초록

An air staged premixed dry low NO x combustor of the type that is constructed of a premixing chamber and a centerbody porous plug premixed flame stabilizer. Such structures of this type maintain very low flame temperatures and, ultimately, low NO x emissions.

대표청구항 ▼

1. An air staged premixed low NO x combustor, said combustor comprised of: a combustion chamber means; a fuel introduction means located adjacent to said combustion chamber means; an air introduction means located adjacent to said fuel introduction means; a premixing chamber means located adjacent said fuel introduction means for mixing said fuel and air; a fuel and air swirler means located adjacent said premixing chamber means; a fuel/air control passage means located adjacent said swirler means; and a porous flame stabilizer means located adjacent said passage means and also located substantially within said combustion chamber such that fuel and air pass through said porous flame stabilizer means. 2. The combustor, according to claim 1, wherein said combustion chamber is further comprised of: a shell having a thermal barrier coating; and a liner having a thermal barrier coating wherein said liner is located adjacent to said shell. 3. The combustor, according to claim 1, wherein said fuel introduction means is further comprised of: a fuel manifold means. 4. The combustor, according to claim 2, wherein said air introduction means is further comprised of: an air passage means located adjacent to said fuel introduction means and which is regulated by the position of said flame stabilizer means; and an air flow dilution means located on said shell at a predetermined distance away from said air controller means. 5. The combustor, according to claim 1, wherein said premixing chamber means is annular. 6. The combustor, according to claim 1, wherein said passage means is adjustable. 7. The combustor, as in claim 1, wherein said stabilizer means is further comprised of: an actuator means; and a porous plate means operatively connected to said actuator means.
