Integrated boiler burner with balanced heat flux

摘要: A package boiler having water cooled surfaces positioned relatively close to the combustion burner improve radiant heat transfer. Extended are added tube fireside surface increase absorption rates limits established by side conditions avoid departure from nucleate boiling (DNB). The release of multiple firing rate zone burners matched adjusting size and extent various zones. is extended or physical shape altered expose a larger greater areas furnace surface. cooling lower temperatures thus thermal NOX formations. Further, recirculated flue gas, excess air, vapor combination these may be used add mass fluid stream flowing through burner. Finally, either gas fuel air staged.
