What are the main features of a water tube boiler?
Main Features
- They usually exist in larger sizes as compared to fire tube boiler designs.
- They are proficient in dealing with steam pressures which can be as high as 5,000 psig.
- Their recovery is much quicker than their firetube counterparts.
- Besides, they are designed to attain extremely high temperatures.
What is meant by water tube boiler?
: a steam boiler in which water to be heated circulates in tubes exposed to fire and enveloped by hot gases — compare fire-tube boiler.
Which one is the water tube boiler?
Water tube boiler: The water circulates inside the tubes which are surrounded by the hot flue gases from the furnace. It generates steam at a higher pressure up to 165 bar. Examples: Babcock and Wilcox boiler, Stirling boiler, La – Mont boiler, Benson boiler, Loeffler boiler etc.
What are the basic parts of boiler?
In this article we’ll take a closer look at the main components that make up a commercial boiler.
- Burner. The burner is the part of the boiler where air mixes with the fuel source and combusts.
- Combustion Chamber.
- Heat Exchanger.
- Controls.
- Supply Lines and Return Lines.
- Circulator Pump.
- Exhaust Stack.
- Conclusion.
What is fire tube boiler with example?
Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water. The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler.
Where are fire tube boilers used?
Fire-tube boilers have the advantage of being easy to install and operate. They are widely used in small installations to heat buildings and to provide power for factory processes. Fire-tube boilers are also used in steam locomotives.
How are water and steam produced in a water tube boiler?
In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
What is the working principle of a bent tube boiler?
Working Principle of Bent Tube or Stirling Boiler. The feed water first enters into right most upper drum. Due to more density this water comes down in the lower water drum. The water within that water drum and the connecting pipes to the other two upper drums, are heated up and consequently steam bubbles are produced.
What are the components of a water tube?
Boiler Shell: This shell is the external cylindrical part of a pressure container. Mud Drum: This is a cylindrical formed space at the base of the water space. The impurities like mud, sediment, and others will be gathered. Strainer: This is a type of device as a filter to hold solid elements letting a fluid to supply.
Which is larger a fire tube boiler or a water tube boiler?
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.
