(ii) High-, Medium-, and Low-Pressure Boilers: (a) High-Pressure Boilers: The boiler which produces steam of more than 70 bar of pressure is known as high-pressure boiler. The efficiency of fire tube boilers has been found quite low. The generation of steam at high pressure and high temperature is not possible in a fire tube boiler.
In fire tube boiler, the hot gases passes through the tubes and boiler feed water in the shell side is converted into steam.; Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressure. Fire tube boilers are competitive for steam generation rated up to 12,000 Kg/hour and pressures up to 10 Kg/cm 2 ; The fire tube boilers are available for

A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high pressure than old ones. This boiler is very used

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.
Because this boiler has 116 general fire tubes and 38 super-heated fire tubes. Locomotive Boiler is an internally fired boiler. That's means boiler furnace located inside the main boiler shell or barrel. This boiler uses solid fuel like coal. It is also a forced circulation, mobile or portable type, and medium pressure fire tube boiler.
Fire tube boiler is one of the most basic types of boiler and the design is also very old. It was popular in 18 th century. It was mainly used for steam locomotive engines. Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace.The hot gases produced in the furnace then passes through the fire tubes.
Fire tube boilers are more commonly available for low pressure steam or hot water applications, and are available in sizes ranging from 500,000 to 75,000,000 BTU input. Water-tube boilers are primarily used in higher pressure steam applications and are used extensively for comfort heating applications.

Fire Tube Boiler. In fire tube boiler, hot gases pass through the tubes and boiler feed water in the shell side is converted into steam. Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressures. As a guideline, fire tube boilers are competitive for steam rates up to 12,000 kg/hour and
Fire Tube Boiler: Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient
In a fire tube boiler, the hot gas passes through numerous tubes and each tube is surrounded by water. Whereas in water tube boilers, the water passes through the tubes and it is the hot gas which surrounds the water tubes. #1. Fire Tube Boilers or Shell Boilers As per industrial usage is concerned, fire tube boilers are the most common types

Comparison between water-tube and fire tube boilers Water Tube boiler Fire Tube boiler Water is inside the tube and flue gases surrounded to it. Flue gases inside the tube and water surrounded to it. Operating pressure is up to 170-180 bar (high pressure boilers). Operating pressure is up to 25 bar (low and medium pressure boilers).
LOCOMOTIVE BOILER Locomotive boiler is a horizontal fire tube type mobile boiler. It is a compact and its capacity for steam production is quite high for its size as it can raise large quantity of steam rapidly. Therefore , this boiler requires a large amount of heating surface and large grate area to burn coal at a rapid rate .

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.
of the metal which is then deformed by the pressure. Bulges may also be caused by creep or temperature gradients. b) A blister may be caused by a defect in the metal, such as a lamination, where the side exposed to the fire overheats but the other side retains its strength due to cooling effect of water or other medium. Blisters

Low Pressure Boilers. Low pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam at pressures below 15 PSI. Though high temperatures within an enclosed space result in increased pressure, these boilers are able to keep pressure at or below the atmospheric pressure of ~14.7 PSI.
The pressuretrol serves to turn the boiler off it the pressure rises above the cutoff setting -- which in your case should be 1 on the diff and 1 on the main, or even better 0.7 on the main. Reset it to where it was! What it doesn't do is raise the pressure in the boiler. The fact that your 0 to 5 psi gauge doesn't move, and the pressuretrol
