In fire-tube boilers, flue gases are inside of tubes, and water is in the shell around the tubes. Steam Applications. In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant

Water-tube design boilers are quite fit for applications needing large amounts of steam, such as industrial process purposes, and are used less often for heating purposes. The benefits of the water-tube steam boiler design include the following: Accessible in sizes far greater than a fire-tube boiler design, up to some million pounds per hour

TYPES OF BOILERS. The boilerman is concerned primarily with the FIRE-TUBE type of boiler. However, the WATER- TUBE type of boiler may occasionally be used at some activities. The information in this chapter primarily concerns the different designs and construction features of fire-tube boilers. The basis for identifying the two types is as follows:

Water tube boilers can operate at pressures up to 5000 psig. Additionally, when used with steam circulating super-heaters, they are capable of reaching much higher temperatures than fire tube boilers. For these reasons, water tube boilers have become the most commonly used boiler type in the modern age.

The first water-tube boiler having fire tubes within water tubes was built in 1830, by Summers & Ogle. Horizontal connections at the top and bottom were connected by a series of vertical water tubes, through which were fire tubes extending through the horizontal connections, the fire tubes being held in place by nuts, which also served to make

There are the tubes that carry the water and/or steam throughout the system; soot blowers that keep the unit free of fly ash or dust by blowing steam water or air into the boiler; burners that burn the fuel (oil, gas, coal, refuse); economizers that recover heat from the exit gas and pre-heat the water used for making steam; and many more such

How Water Tube Type Steam Boilers Work. One of the latest advances in steam boiler technology is the use of water tube boilers.This type of boiler is distinct from conventional fire tube boilers. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel. They are also much safer than fire tube boilers and easier to manage when it comes to routine
