2008-1-4 · This boiler has a 3-level air system. The primary air level is very near the bottom of the furnace. The secondary air level is about 5 feet above the primary level and 10 to15 feet below the liquor gun level. The tertiary air level is 10 to 15 feet above the liquor guns. Most recovery boilers have three levels of combustion air, but some have two

Get A Quote2006-4-4 · From the results of experiments reviewed, it could be concluded that due to sudden devolatilization of biomass fuels, combustion operations should be conducted in an environment of high excess air. Splitting the total air into primary air and secondary air and supplying them at the appropriate levels could improve combustion efficiency.
