Water Tube Boiler - Types, Working, Construction

Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

Lay-up of Heating Boilers

The steps of preparing a boiler for wet lay-up are essentially the same for dry lay-up. The exception is when a boiler is closed and prepared to be filled with water and water treatment chemicals. Perform dry lay-up steps 1-6 (except do not swab the fireside with mineral oil) and then follow with step 7 below.

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
