Cross Drum Boiler is essentially a variant of the Longitudinal Drum Boiler.In Cross Drum Boiler the steam drum is placed at cross ways to the heat source as shown in the figure. Here, the down-comer is fitted on the bottom of the drum and riser is fitted on the top of the drum via a horizontal tube as shown in the figure. 5 o to 15 o inclined water tubes are connected with down-comer and riser ...

These steam bubbles then come to the steam drum through riser and naturally separated from water and occupies the space above the water surface in the longitudinal drum of Babcock – Wilcox Boiler. Cross Drum Water Tube Boiler Construction of Cross Drum Water Tube Boiler. Cross Drum Boiler is essentially a variant of the Longitudinal Drum Boiler.

A high pressure watertube boiler[1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace ...

A cross-tube boiler was the most common form of small vertical boiler.They were widely used, in the age of steam, as a small donkey boiler, for the independent power of winches, steam cranes etc.. The boiler has the advantage of simple robust construction, in particular requiring little regular maintenance.

Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.

Water Tube Boiler Components of Water Tube Boiler. The water tube boiler can be built with boiler shell, burner, mud drum or mud ring, furnace, safety valve, strainer, sight glass, feed check valve, steam stop valve, etc. Boiler Shell: This shell is the external cylindrical part of a pressure container.

Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be
