Reducing Steam Consumption of Flue Gas Desulfurization Regeneration Process by Applying Continuous Boiler Blowdown
Currently,the desulfurization regeneration process requires a large amount of low-pressure steam.When the power workshop cannot supply enough steam,additional purchases are needed.In addition,the instability of steam supply leads to poor regeneration effectiveness.The boiler discharges continuously using saturated water at a pressure of 4.5 MPa and a temperature of about 250℃,resulting in energy waste and unfavorable on-site management.In order to reduce the operating costs of the desulfurization regeneration process and enhance desulfurization effectiveness,a port is added to the steam inlet pipe of the desulfurization reboiler to introduce the discharge into the reboiler for replenishment.The steam generated from the discharge is utilized.The results show that this method can reduce steam consumption,increase the concentration of the ionic liquid,and reduce the amount of organic amine added.In conclusion,this method achieves the goals of cost reduction and enhanced desulfurization effectiveness.These research results are of great significance for the optimization of the desulfurization regeneration process and environmental sustainability.
