how to reduce boiler flue gas sulfur dioxide content

Low Temperature Corrosion in Boiler and Its Prevention

Other technologies include spray-dry scrubbing, which also uses sorbent slurries; a wet sulfuric acid process that recovers the sulfur in the form of sulfuric acid; dry sorbent injection systems; and a flue gas desulfurization technique known as SNOX, which uses catalytic reactions to clean flue gases of nitrogen oxides (NO x) and particulates, as well as sulfur dioxide. Newer technologies can remove more than 90 percent of …

A Method of Reducing the SO2 Emission from Power Boilers

The process consists in introducing a lime or dolomite sorbent into the boiler's combustion zone. Chemical reduction occurs at the temperature of 900–1000°C that lets reduce the SO 2 concentration by ca. 35%. After leaving the boiler and passing through a rotational air-heater, the combustion gas enters a reactor, which is a special-purpose variation of the boiler flue's vertical segment.

Flue Gas Desulfurization Reducing Acid Rain | Howden

To do this an alkaline-based sorbent is used to bring the pH level of the sulfur dioxide gas closer to neutral. Scrubber systems are one of the most efficient ways of reducing sulfur dioxide emissions caused by industrial combustion, and a classic example of an acid-base chemical reaction performed on an industrial scale. Flue Gas Desulfurization Systems: Scrubbers. Flue gas desulfurization systems (FGD) …

10 Some Methods of Reducing Sulfur Oxides from Power

content in the residual materials, sulfur-dioxide (SO 2) gas shall be reduced of course, and sulfur-trioxide (SO 3) gas, which is furthermore oxidized from SO 2 and forms sulfuric acid (H 2SO 4) mist combined with water vapour in the flue gas, shall also be reduced, since the sulfuric acid mist causes serious corrosion problem in the flue gas treatment system and
