Steam/water circulation design - KTH

The water/steam circulation begins from the feed water tank, from where feed water is pumped. The feedwater pump (Figure 6) raises the pressure of the feedwater to the wanted boiler pressure. In practice, the final steam pressure must be under 170 bar in order for the natural circulation to work properly.

Basic Layout and Working of a Thermal Power Plant

Boiler: The mixture of pulverized coal and air (usually preheated air) is taken into boiler and then burnt in the combustion zone.On ignition of fuel a large fireball is formed at the center of the boiler and large amount of heat energy is radiated from it. The heat energy is utilized to convert the water into steam at high temperature and pressure.

protective oxide films (passive films) under boiler conditions (low or zero oxygen levels). However, sulfite is not considered to be a good passivating agent because it does not passivate low pressure boilers, where sulfite is most often used. Passivation can be accomplished in high pressure boilers, but high dosages of sulfite are needed.
