NOTE: The Titanic was powered by 29 firetube boilers that contained furnaces which were fired with tons of coal per day. A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) .. "Taco Radiant Made Easy Application Guide – Setpoint Temperature: Variable Speed Injection Circulators – March 1, " (PDF). taco- echecs16.info STEAM-MATIC SG fire tube steam boilers produce saturated or superheated steam, with design pressure range from 12 bar up to 30 bar. Range of.
Fire tube boilers are a portable boiler and it requires a small floor space. Construction: Fire tube boiler consists of a vertical, cylindrical shell, equipped with a fire box in the bottom, water space in the middle portion and steam space in the upper portion. The fire grate is placed at the bottom of the fire box and coal is fired at the fire box. An ash pit is located at the bottom of the grate to collect the ash of burnt coal, which is periodically removed. One or more cross tubes are either flanged or riveted to the water space are located in the fire box to increase the heating surface area to improve the water circulation. A short chimney is connected at the top of the fire box to discharge the waste flue exhaust gases at some greater height. Manhole and hand holes are provided for cleaning the interior of the boiler shell and cross tubes.
The fire tubes are immersed in water inside the main vessel of the boiler.
As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them. 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.
As the steam and water is stored is the same vessel, it is quite difficult to produce very high pressure steam from. General maximum capacity of this type of boiler is In a fire tube boiler, the main boiler vessel is under pressure, so if this vessel is burst there will be a possibility of major accident due to this explosion.
Types of Fire Tube Boiler According to the location of furnace there are two types of fire tube boiler and these are external furnace and internal furnace type. There are mainly three types of external furnace fire tube boiler. Horizontal return tubular fire tube boiler.
Short fire box fire tube boiler. Compact fire tube boiler. There are also two types of internal furnace fire tube boiler Horizontal tubular.
Vertical tubular fire tube boiler. The water surrounding the cylindrical fire box also receives heat by convection and radiation.
Thus steam is produced. The water circulation in the boiler depends on the density difference in water, created by the temperature difference in water.
