Super low NOx, high efficiency, compact firetube boiler |
摘要 |
A firetube boiler furnace having two combustion sections and an in-line intermediate tubular heat transfer section between the two combustion sections and integral to the pressure vessel. This design provides a staged oxidant combustion apparatus with separate in-line combustion chambers for fuel-rich primary combustion and fuel-lean secondary combustion and sufficient cooling of the combustion products from the primary combustion such that when the secondary combustion oxidant is added in the secondary combustion stage, the NO<SUB>x </SUB>formation is less than 5 ppmv at 3% O<SUB>2</SUB>.
