Good quality Industry Boiler Pressure and Superheater Tubes EN 3834 Welding procedure

Description of Superheaters

1. Whatever type of boiler is used, steam will leave the water at its surface and pass into the steam space. Steam formed above the water surface in a shell boiler is always saturated and cannot become superheated in the boiler shell, as it is constantly in contact with the water surface.

2. If superheated steam is required, the saturated steam must pass through a superheater. This is simply a heat exchanger where additional heat is added to the saturated steam.

3. 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.

Benefits of using a Fired Steam Superheater

• The efficiency of the process heating system is optimised.
• Condensation formation in the steam distribution system is reduced.
• The risk of water hammer or mechanical damage is alleviated.
• Pipework sizing is optimised.
• The lifespan of the heating system equipment is extended.
• Fuel consumption is optimised.
