Sir,does that initial heating line is for increasing the inside surface temp of FST?

[@kpatelbla]

Yes

[@motive0507]

For what purpose sir?

[@kpatelbla]

Initial heating of FST water to prevent hammering

Initially Deaerator FST temperature at atmospheric and after starting of steaming in Boiler we can not take this water through Bfp otherwise there will be chances of hammering that is why initial heating must be charged
