LEAN PREEVAPORATION AND PREMIXTURE COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To provide a lean preevaporation and premixture combustor for reducing the amount of NOx and CO in combustion gas while effectively preventing the production and accumulation of carbon in a preevaporation and premixture pipe. SOLUTION: The lean preevaporation and premixture combustor 10 comprises a fuel injection valve 12 for injecting liquid fuel 1 into an air flow, the preevaporation and premixture pipe 14 for evaporating the liquid fuel 1 and mixing it with air 2 into uniform lean combustion concentration, and a combustor liner 16 connected to the preevaporation and premixture pipe 14 and having a combustion chamber 18 formed inside for burning the lean mixture. The preevaporation and premixture pipe 14 is protruded into the combustor liner 16. COPYRIGHT: (C)2006,JPO&NCIPI
