REDUCTANT SUPPLY DEVICE AND REDUCTANT SUPPLY METHOD IN DENITRIFICATION SYSTEM

摘要

The present invention relates to a reductant supply device for supplying a reductant into a denitrification system for exhaust gas denitrification and, more specifically, to a reductant supply device and a reductant supply method in a denitrification system, by which cost reduction and the efficiency of maintenance can be improved by enabling a control through a one-directional check valve mounted on a line connecting a dosing part and a spraying part even without additionally mounting a separate control panel between the dosing part and the spraying part unlike the prior art when cleaning the spraying part in which a reductant remains and the line.
