Bi- drum and Single Drum Boilers - Bright Hub Engineering

Single drum boilers are used mainly for power generation. With supercritical pressure boilers coming into use, even the single drum gets eliminated. This type of boiler has the advantage that they can be designed for very high pressure, flow, and temperature.

Steam drum - Wikipedia

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 So, due to the high heat rate of the plant a single drum boiler or a once
