View MoreIn a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.
View MoreIt is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that allows more heat transfer time to deliver the same or higher efficiency rating than a 4-pass boiler with standard tubes. 3 pass firetube boilers offer: maximized heat transfer; minimal refractory; high steam/water storage; effective handling of wide load demands
View MoreFeb 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:
View MoreOct 27, 2020· 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 …

View MoreAug 12, 2020· A Significant Difference Between Fire-tube Boilers and Water-tube Boilers One significant difference between these two boilers that has affected the design of systems is the fact that higher mass boilers do not need to maintain a constant flow. Fire-tube boilers can handle a …
View MoreEver wonder how your boiler is creating steam? Today on the Boiling Point, Ritchie talks with Steven Taylor about how a firetube steam boiler works. Boiler's
View MoreThese design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the …
View MoreThe design temperature for the hot water boilers can be up to 200 o C. The double fire-tube boiler with water-cooled reversal chamber and burner penetration has a capacity of 70 t/h and pressures of 0.5 to 40 bar (g). As hot water boilers, the capacity is between 0,5 and 44 MW. The design temperature for the hot water boilers can be up to 200 ºC.

In addition to steam generation, a large number of fire tube boilers are used to heat hot water for residential or commercial use. Sign in to download full-size image
View MoreOur engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering team’s design.
View MoreThis design requires only 10% of the water that’s typically found in conventional fire tube boilers and helps give the LX model 85 percent fuel-to-steam efficiency. Most fire tube boilers will max out at 83 percent fuel-to-steam efficiency. However, this small difference can amount to anywhere between 10 and 40 percent savings in fuel costs.
View MoreFire-tube boilers offer a compact and economical design for lower steam production rates. A fire-tube boiler will be the only choice for processes needing 300 Hp capacity or less. While every situation needs to be evaluated on it’s own merits, a fire-tube boiler is usually the most economical for 1,200 Hp or less, however units are available
