DEVICE FOR DISCHARGING AND DISTRIBUTING AN ABSORBENT MATERIAL IN A FLUE GAS DUCT

摘要

In a vertical flue gas duct (10), in which flue gases containing gaseous pollutants are to be conducted upwards, a discharging and distributing device is arranged. The device is adapted to discharge and distribute a particulate absorbent material which is reactive with the gaseous pollutants in the flue gases and which, during cleaning of the flue gases, is to be introduced into these gases in moistened state in order to convert the gaseous pollutants to separable dust. The device comprises at least one distributing plate (35) which extends obliquely downwards in the flue gas duct (10) and which is adapted to receive on its upper side moistened absorbent material and which has two well-defined side edges converging obliquely downwards seen in the direction of inclination.
