Answer / meet vekaria

The outlet temperature of HP heaters should be 240 degrees and that will be inlet temperature of economiser.
the temperature limit of economizer is bounded and so we cant fed feed water more than 240 degrees in economiser.

Answer / instqust

Hi...Generally Spray is used for temperature REGULATION purpose only, either Steam or Water Temperature control applications.

Answer / velmurugan

As we all know that the attemperator main purpose is to reduce the temperature of superheater steam..If we take water after feed pump or LP heater its temperature is slightly lower than the hp heater ,so there is a possibility of superheated steam condense in an attemperator itself by using lp heater or feed pump water..
