كواحد من قادة sulfur content requirements for fgd systems الصناعة ، تسعى SBM دائمًا إلى الابتكار والتميز.
Dry Flue Gas Desulphurisation / Lime Spray Drying FGD systems LSD is a dry scrubbing process that is generally used for lowsulfur coal. Flue gas with high sulphur content from boiler is tapped off from the last heat trap after the Economiser/ air preheaters by mixing the gas stream concurrently with lime slurry droplets for chemical treatment.

EFFECT OF COAL PROPERTIES ON FGD SYSTEMS The major coal properties affecting FGD system design and operation are heating value and sulfur, ash, moisture, and chlorine content. The effects include: • Heating value of coal. Affects flue gas flow rate — generally higher for lower heating value coals which also contribute a greater water vapor content to the flue gas • Moisture content ...
