What are desulfurization methods of coal fired industrial boiler


At pretest,coal remains the primary fuel for industrial boiler,without desulfurization,nearly all sulfur in the coal will transform into sulfur dioxide after combustion,the sulfur dioxide will cause serious environmental pollution,so,desulfurization is an important part to protect the environment.The main desulfurization methods of coal fired industrial boiler are the following ones.


The desulfurization before coal combustion


The common way of that is coal washing,using the physical treatment to eliminate the sulfur in coal.


The desulfurization in the furnace of coal fired industrial boiler


The common way is adding sulfur fixing agent in the coal,the sulfur dioxide produced in the combustion,reacts with the sulfur fixing agent,forming the solid compounds,then,they are discharged with the slag.According to information,this is by far the most economic, practical, widely used method.


The flue gas desulfurization of coal fired industrial boiler


After coal combustion,although two desulfurization programs have been processed,we still can not reach the complete desulfurization,the flue gas also contains sulfur dioxide,the flue gas desulfurization is mainly the recycle of sulfur,the method is that adding absorbents in the cyclone dust removal desulfurization tower, they react with flue gas,forming sulfate,the sulfate is discharged into the dust pool,reaching the effect of desulfurization.
