A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

concentration in boilers water as shown in fig. 1. Figure 1: Phosphate treatment systems used in boilers [1]. The most popular treatment for low pressure boilers (< 600 psi) is dosing of tri-sodium phosphate (TSP), it reacts with water at high temperature and gives sodium hydroxide to increase boilers water pH as shown in equation (1).
