Power Plant Gyan

Typical power-plant cycles which incorporate the natural-draft hyperbolic cooling tower are shown in the schematics. FIGURE  Introduction:- 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 . A nuclear plant is even less efficient , converting only about 33% of its heat energy input into power , with 62% discharged to cooling water & 5% lost. Remember, nonetheless, that heat discharges from electric power plants are among the lowest of all energy-conversion processes.   A natural draft hyperbolic cooling tower are evaporative in design , they contain no fans. Working principle:- Flow of air through shell is created by the density difference between atmospheric air and that inside the tower which has been warmed by the hot water from plant condensers. As with the mechanical-draft-type, two basic airflow schemes in relation
