SCHEME OF DEAERATOR WITH CONNECTIONS
TABLE OF CONTENT 1:- Deaerator an introduction 2:- Deaerator connections 3:- Deaerator schemes DEAERATOR AN INTRODUCTION 1. Highest vessel in the system. 2. Remove dissolved gases. 3. Used for heating of feed water. 4. Reduce the amount of steam in the system and hence energy flow to the plant. 5. Extraction steam enters from the bottom of the tanks. 6. Steam passes over the water droplets. 7. As the extraction steam condensed the water droplets releases the non-condensable gases vented to the atmosphere. 8. The deaerated feed water & condensed steam mixed and drained out to the FST. 9. FST supply feed water to the boiler feed pumps. 10. Acted as a open type feed water heater. CONNECTION 1:-One pipe line coming from CEP discharge via through ejectors, GSC D/R coolers LPH-1, 2, 3 which supply the water to the Deaerator. 2:-Two pipe lines are connected to the Deaerator which are coming from HPH-5 & HPH -6 drips. 3:-Two vent pipe lines are connected to the Deaerator tank coming f
