Miscellaneous Boiler Types Economisers and Superheaters | …

In water-tube boilers, the superheater may be an additional pendant suspended in the furnace area where the hot gases will provide the degree of superheat required (see Figure 3.4.4). In other cases, for example in CHP schemes where the gas turbine exhaust gases are relatively cool, a separately fired superheater may be needed to provide the additional heat.

Water Tube Boilers – Industrial Steam Boilers | Water Treatment Services

Water tube boilers are a special type of steam generator that tend to be used in large scale industrial and commercial applications. They are different from shell boilers because they circulate hot water around a series of tubes to allow the heat transfer process to take place. The heat source used to heat the water in a tube boiler

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

What is a Superheater? (with pictures) - Info Bloom

A convection superheater can be extremely efficient, because most of the thermal energy is given only to the boiler tubing, and what would normally be exhaust instead heats the superheater tubes. These are also found in power plants, but they were mostly implemented in steam locomotives.

Water Handbook - Boiler System Failures | SUEZ

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …

The top water wall headers in water tube boiler have a mixture of steam and water and this is returned to the steam drum via tubes known as risers. Superheater Tubes: Once water gets converted to steam, its temperature needs to be raised further to pump in more energy in the steam and this is done by imparting thermal energy to the steam in the form of superheat.
