Introduction To CFPP | Boiler | Steam

RANKINE cycle is the simplest theoretical vapour cycle, which is the basis for operation of a steam plant. Rankine cycle is a heat engine with vapor power cycle. The common working fluid is water. Steam is produced in the boiler by utilising the heat of coal combustion. The steam is then expanded in the prime mover (i.e steam turbine) and is condensed in a condenser to be fed in to the boiler
