Why reheater is not used after IP turbine.

Answer Posted / y v subba rao

The specific volume of steam coming out of ip turbine is very high. We can not accommodate re-heater in boiler which can handle such high volume steam. Design such type of boiler is very difficult and un economical. More over increase temperature of low pressure steam will not yield any additional benefit. However we have to reduce the temperature to 45 degrees before leaving to condenser. It is very difficult if we use re heater after ip turbine.
