A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.
In a water-tube boiler ('''Figure 3'''), the water is inside the tubes and combustion gases pass around the outside of the tubes. The advantages of a water-tube boiler are a lower unit weight-per-pound of steam generated, less time required to raise steam pressure , a greater flexibility for responding to load changes, and a greater ability to
Also called D type water tube boilers, they are the most common type of small- to medium-sized boilers. The upper drum, called a steam drum, is where saturated steam leaves the boiler. The lower drum , called the mud drum, receives the liquid feedwater and collects sediments that are carried into the boiler and settle at the bottom of the drum.
Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.
In a fire-tube boiler, the entire tank is under pressure, so if the tank bursts it creates a major explosion. More common today are water-tube boilers, in which water runs through a rack of tubes that are positioned in the hot gases from the fire. The following simplified diagram shows you a typical layout for a water-tube boiler:
Jun 18, 2014 · How to run a hot-water zone off a steam boiler. The fill pressure and tank size determine how high you can place the radiation above the boiler's water line. The only limit is the working pressure of the equipment you're using. It takes 1 psig water pressure to raise water 2.31 feet straight up.
The main two basic boilers are: Water tube boiler ; Fire tube boiler ; The design and arrangement of both the types is just the opposite. In water tube boilers, the feed water passes through the tubes and the hot gases are made to pass over them, while in fire tube boilers, the hot gases passes through the tubes and the feed water surrounds them.
Mar 10, 2016 · Flue gases passes through the fire tubes and side and bottom space. The water level inside the drum is always above the side channels of flue gases, so more heat transfer to the water. The drum is half filled with water and the upper half space for steam. The Furnace is located at one end of the fire tubes inside the boiler.
