A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Tube failures form a major portion of the forced outages of boilers. A good percentage of these failures are due to long term overheating. These failures can be avoided when we understand the reason and operate the boiler accordingly. Long term overheating failures are due to the fact that the operating metal temperature of the boiler tubes going above the allowable limit.

Marine boilers are of two types namely the water tube boiler and the fire tube boiler. The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a small fire tube boiler would be satisfactory.

Based on different working temperature, the medium or high pressure boiler pipe shall be used. Normally classified as below cases: a. The operation temperature of general boiler pipe is lower than 450℃. The medium pressure boiler pipeline mainly adopts hot rolling process or cold drawing process. b.
View MoreOnce a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating. If you notice that your boiler’s temperature is going higher than the above settings, you have a major problem. If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking.
