Longitudinal Drum Hot Water Boiler Related Information

Three-drum boiler - Wikipedia

A boiler stored in hot standby with the unit full of water must be properly managed to prevent oxygen corrosion of the unit. The unit must be slowly brought down in rating while raising the water level as high in the gauge glass as possible while still delivering export steam to the line.

Boilers : Types and Classification

Longitudinal drum boiler The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 1). Cooler feed water is fed into a drum, which is placed longitudinally above the heat source. The cooler water falls down a rear circulation header into several inclined heated tubes.
