During normal operation, the water supplied to the quench ring is (), and if make-up water is used, it is added in (), with the purpose of (). During normal operation, the water supplied to the quench ring is (recycled black water within the system); if make-up water is used, it is (deoxygenated softened water), and the purpose of this is to (prevent pipe corrosion and scaling).
Circulated black water, deoxygenated gray water, metal equipment protected against oxygen corrosion
Under normal operation, the water supplied to the quench ring is the black water that is recycled within the system; it is pumped from the scrubber tower via pump P-1305 into the quench ring. The flow rate is 218 M3/h, the temperature is 247°C, and the pressure is 7.5 MPa. The water within the system is recycled; supplementary water is deoxygenated soft water. The use of deoxygenated soft water serves to prevent pipe corrosion and scaling.
Circulating black water within the system ----------- Deoxygenated softened water ------------ Pipeline corrosion and scaling
(Circulated black water), (deoxygenated gray water), (to prevent oxygen-induced corrosion of metal equipment)
Circulated black water: Deoxygenated black water, used to prevent oxygen-induced corrosion of metal equipment

Deoxygenated soft water prevents pipe corrosion and scaling
During normal operation, the water supplied to the quench ring is (recycled black water within the system); if make-up water is used, it is (deoxygenated softened water), and the purpose of this is to (prevent pipe corrosion and scaling).
