VACCUM PULLING
Close RH vents (IP turbine and LP turbine direct coupled if RH vents not closed then air from atmosphere is coming in the condenser via IP and LP turbine) & close vacuum breaker valve (It directly connected condenser) and Water sealing (water is used as a seal fluid for vacuumRead More
BARRING GEAR & AVOIDING STALLING
Barring gear is mechanism which rotate turbine shaft (with generator) when motive steam is not available i.e. when turbine is in trip condition. Steam turbine is on barring means turbine shaft rotates on a speed of 60-90 rpm without vacuum & while on vacuum rotates 120-140 RPM. At this lowRead More
FEED WATER SYSTEM
INTRODUCTION The source of feed water is FST into the feed water system, (in other words, we may say that FWS starts here). In FST water coming from Deaerator after deaeration process & stored in to feed storage tank (also initial make up line is provided used for pre fillingRead 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
