Mineral build-up resulting from the use of tap water in model boilers can severely reduce the efficiency of the boilers if run for long periods. This build-up is called boiler scale.
Apr 23, 2016 · Fire Tube Boiler. It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that’s why they fall under the category of low pressure boilers.
A fire-tube boiler is a type of boiler in which hot gases from the fire pass through one or more tubes within the boiler. It is one of the two major types of boilers, the other being the water-tube boiler. A fire tube boiler can be either horizontal or vertical.
Jun 25, 2014 · This is a problem you'll sometimes run into with residential steam boilers. If the sections are too narrow, the rising steam bubbles will lift the boiler water level to a point higher than the level in the gauge glass. This happens because there isn't any steam in the water that's in the gauge glass.
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
Do you mean "why a fire-tube boiler instead of a water-tube boiler," which eliminates the need for staybolts? Water-tube boilers were tried on locomotives, and their advantages (higher pressures, etc.) were outweighed by disadvantages in construction and maintenance. Do you mean "why have a stayed firebox instead of an unstayed firebox?"
Aug 22, 2018 · As a result steam is generated in the water and naturally comes up and is stored upon the water in the same vessel of fire tube boiler. This steam is then taken out from the steam outlet for utilizing for required purpose. The water is fed into the boiler through the feed water inlet.
Fire Tube Boiler. The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.

Boiler. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect. A conventional boiler has a furnace that burns a fossil fuel or, in some installations, waste fuels.
In case of bombers fire tube boiler would be very dangerous if a large amount of hot water and steam have been accumulated inside (leakage occur). 4. The fire tube boiler can not produce steam at a pressure higher than 250 pounds per square inch.
In a watertube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. In a firetube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Firetube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers).
In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of moisture are erased. This is called superheated steam.
It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.
Sight Glass: A glass tube used on steam boilers to give a visible indication of the boiler’s water level. Drain: A valve connection at the lowest point for the removal of all water from the boiler. Feed Pump: A pump that supplies water to a boiler.
