Water Tube Boiler – Working Principle, Types of Water Tube

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

High Pressure Boilers: Meaning, Types, Characteristics

As at critical pressure steam and water co-exist at the same density and no bubble formation occurs. Further at critical pressure the enthalpy of evaporation (Latent heat) is zero. The water thus gets converted into steam directly without passing through evaporation process. It is a high pressure, water tube, forced circulation boiler.

Scaling in boilers

In general, boiler deposits can cut operating efficiency, produce boiler damage, cause unscheduled boiler outages, and increase cleaning expense. The first anti-scaling preventative measure is to supply good quality demineralised water as make–up feed water. The purer the feed water is, the weaker the driving mechanism to form scale.
