By separating the coarse slag

avoiding the high temperature large size slag contacting with the water directly

prolonging the cooling time and reducing the cooling water amount

the wet slag removal system with no overflow water realized "zero overflow".The procedure

structure and sealing connection methods between each component of this wet slag removal system were presented in detail.According to the calculation

the water consumption of this "zero overflow" system will be about 0.5t/h to 0.6t/h

and over 88.6%of the total heat of hot slag can be recovered

realizing the purpose of energy-saving and emission reduction.Besides

this system can increase the steam temperature and reduce the gas phase corrosion

and with no water explosion.
