What to do if SO2 levels are too high in biomass boilers?
Biomass fuels are all wooden in nature, generally have low sulfur content, and should meet the standards. It is possible that the boiler’s combustion condition is poor, with an excessive oxygen level, which results in a high conversion factor; sulfur levels may also be above the limit, and the combustion conditions can be adjusted. Finally, if the levels do exceed the limits, considering installing an alkaline spray system to absorb sulfur dioxide could be an option.
