Steam Generator versus Steam Boiler - AB&CO

The Disadvantages using a steam generator compared to fire-tube steam boilers are: Not able to have even small and short peaks in steam consumptions beyond the maximum capacity. Separate buffer arrangement to be added. Not capacities above 3.000 kg/h.

Finding the Root Cause of Boiler Tube Failures

Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube

A high steam output (up to 500 kg/s). High pressure steam (up to 160 bar). Superheated steam (up to 550°C). However, water-tube boilers are also manufactured in sizes to compete with shell boilers. Small water-tube boilers may be manufactured and assembled into a single unit, just like packaged shell boilers, whereas large units are usually

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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-pressure tank

Firetube vs Watertube Boilers: a Comparison

Feb 19, 2015 · 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. Here are a few key differences between the two: Firetube Boilers: - compact construction.

Mar 12, 2012 · The fire tube boiler was created in the 1800s, Fig. 1.7.Its main use was to run steam engines for motive power. One of the first brand names for this type of boiler was the Lancashire boiler, which used two parallel fire tubes. It was used to power steamboats and railroad engines and to run industrial machinery via belt drives.

Boilers : Types and Classification - Forbes Marshall

Fire 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. Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.

The other type is a water tube steam boiler. It is just the opposite of the fire tube steam boiler; the water is in the inside of the tubes and the hot gases are on the outside of the tubes. In the fire tube boiler, we have a limitation on the combustion chamber diameter and length, and it cannot exceed a certain value.
