  • Method for operating manufacturing equipment including heating furnace
    Patent number: 6669470
    Abstract: A method for operating manufacturing equipment including a heating furnace is provided. The method comprises the step of spraying a blowdown water that has been in the manufacturing equipment into effluent gas discharged from the heating furnace so as to vaporize the blowdown water and remove solid dust contained in the effluent gas. In a plant implementing this method, the amount of the effluent water can be reduced to substantially zero, no purification equipment is required, and solid sludge which has been produced in the purification equipment is thus completely reduced. Moreover, in this method, iron and zinc can be recycled as fly ash which can be easily treated and recycled.
