Fire-tube boiler

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.

Basics of Steam Boiler – IspatGuru

Every boiler is designed to transfer as much thermal energy as possible to the water contained in the boiler. Heat energy is transferred by conduction, convection and radiation. The relative percentage of each is dependent upon the type of boiler, the designed heat transfer surface and the fuels that power the combustion.

Boiler Basics: Breaking Down the Boiler Room

Heat is generated by the aptly named burner, which burns a fuel such natural gas to produce a very hot flame that runs underneath the full length of the heat exchanger, surrounding the heat exchanger above with the hot combustion gasses produced by that flame, heating the water within. When the boiler turns on, a pilot assembly provides a spark ...

Applying ASME Boiler Code to Steam Generation Systems

(Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and ...

Scaling in boilers

Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.

Steam Boiler: August 2011

Recovery of several of heat losses can be performed by economizer which utilizes flue gas to heat boiler feedwater or utilize flue gases to heat combustion air via air heater. These methods of boiler heat recovery will certainly increase the overall thermal efficiency and efficiency of steam boiler.


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. A fire-tube boiler is sometimes called a "smoke-tube boiler" or "shell boiler" or sometimes just 'FIRE PIPE'

What is the best heating system for new home construction?

Without diving into the many details of each system type, your choices are, for the most part, as follows: electric baseboard, forced air systems (furnace or heat pump), and hydronic heating systems (fin tube baseboard, radiators, and/or radiant in-floor systems). As a reminder, hydronic systems use hot water from a boiler to heat your home.

What are the types heat transfer taken in boiler?

Best Answer: Three different types of heat transfer occur in a boiler. Some type of fuel is burned and the combustion is the heat source, or some type of superheated fluid circulates through transfer tubes to heat boiler feed water. Convection from heated gases around the heated boiler tubes and circulating boiler feed water within the boiler ...

Steam Boiler: Types and Designs

It is also cheaper to purchase than a water tube boiler. However, it also comes with distinct disadvantages, including a limitation on the steam pressure it is capable of producing. Water and steam are kept in the same vessel; so, because the fire tubes are trying to heat a vessel full of water, it takes longer to bring the water to temperature.

BOILER CONSTRUCTION : D-type boiler construction

The rearwall tubes are two inch tubes which protect the boiler rearwall refractory from the heat of combustion and generate some steam. NOTE: By using wall tubes, more of the heat in the furnace is absorbed by water and less refractory material is required, thereby increasing boiler efficiency and reducing the boiler weight.
