Title: Flashback resistant fuel staged premixed combustor

Abstract

A combustor system is described, comprising: a combustion chamber for combusting a mixture of a first fuel and air; a liquid fuel introduction means substantially located within said combustion chamber; premixing combustor tubes for premixing said first fuel and air in said tubes before said first fuel and air enter said combustion chamber, said tubes having first and second ends with holes located along said first end and said second end being substantially located within said combustion chamber; wherein said premixing tubes are further comprised of a bundle of tubes substantially centered around said liquid fuel introduction means with said bundle being divided into at least three consecutive rings of tubes said consecutive rings being of varying diameters with said third ring encircling said second ring which encircles said first ring; a fuel introduction means connected to said first end of said premixing combustor tubes for introducing said first fuel into said tubes; an air introduction means for introducing air into said premixing combustor tubes; and control means for controlling said first fuel, said liquid fuel and said air while maintaining low emissions and a low flame temperature in said combustion chamber, wherein said combustor chamber is further comprised of:more » an outer wall; an inner wall; a heat resistant coating located substantially along a portion of said inner wall; and perforations located substantially along another portion of said inner wall and along a portion of said outer wall.« less
