DEAERATOR IN THERMAL POWER PLANT
DEAERATOR AN INTRODUCTION Remove dissolved gases. Highest vessel in the system. Used for heating of feed water. Reduce the amount of steam in the system and hence energy flow to the plant. Extraction steam enters from the bottom of the tanks. Steam passes over the water droplets. As the extractionRead More
NATURAL DRAFT COOLING TOWER
Typical power-plant cycles which incorporate the natural-draft hyperbolic cooling tower are shown in the schematics. Note that only 40% of heat-energy input is converted to power in the fossil-fuel plant, while 45% is discharged to condenser cooling water; the remaining 15% is lost up the stack & in the ash.Read More
