What is the concentration of phosphate which injecting in boiler feed water as a descaler?
Phosphate(PO4) is basically reacts with mineral dissolved salts in water and percipitates at high temperature. Generally we maintain 10 - 30ppm PO4 inside steam drum to avoidany deposition.
What happens to the steam after it has been used in the fossil fuel power station?
After moving the blade of the turbine , steam gets falls down in a pit where it gets accumulate and converts to water .again the pump tack up that water removing dissolved oxygen in deairater goes to feed pump , which again feeds to boiler. This the closed circuit .

What is Boiler feed pump?
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction

In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
