Hybrid System for fouling control in biomass boilers - …

1/12/2006 · Biomass fouling not only influences the steam production, but also produces other important effects on boiler performance. A boiler efficiency reduction, an increase in carbon dioxide emissions, or a deteriorated combustion behaviour with higher combustion temperatures and an extra formation of nitrogen oxides and carbon monoxide have been reported.

Scaling in boilers - Lenntech

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.
