WATERTUBE BOILERS Longitudinal Straight Tube Boilers Fig. 1 illustrates one of the earliest straight tube boilers. The drum runs longitudinally in relation to the tubes. The straight inclined tubes run between vertical headers at the front and rear of the drum; these headers are connected to the drum at their top ends. The combustion gases make three passes across the

The water wall tubes directly under the tube banks are sometimes referred to as the super-heater floor tubes. In Figure 1, notice that the placement of the primary and secondary super-heater tube sections is in the middle of the unit, directly between the convection pass (heat recovery area) and the furnace area of the boiler.

Water tube marine boilers - Lars Josefss

A water tube marine steam boiler consists of a large number of closely spaced water tubes connected to one or more drums, which act as water pockets and steam separators, giving rapid water circulation and quick steaming. On their way to the funnel the flue gases from the boiler pass a superheater and an economizer. In many marine boilers an air preheater is installed after the economizer, to ...

What are the Different Components or Parts of a Boiler .

In order to increase the insulation of boilers, we use the water wall tubes. In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed tubes and membrane Wall.

Water Tube Boilers have no crown sheet. Water circulates around the walls of the furnace then up to a drum on top of the boiler. They it travel through water tubes inside the furnace where it is converted to steam. Superheater tubes go into the furnace the same way. The setup allowed for more water to be boiled in a given period of time.
