Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness. Second, we add chemicals to the feedwater to adjust the pH, create less favorable conditions for deposition, and remove oxygen. Special water treatment chemicals are used in almost all boilers.
Condensing boiler The efficiency of a hot water central heating boiler is limited in part by the latent heat of vaporization in the water vapour in the flue products. If a secondary heat exchanger is added to the boiler it is possible to cool the flue gases sufficiently to release this latent heat, provided that the return temperature is sufficiently low (i.e. below about 55°C).

For the same output the outer shell of fire tube boilers is much larger than the shell of water-tube boiler. Water tube boilers require less weight of metal for a given size, are less liable to explosion, produce higher pressure, are accessible and can respond quickly to change in steam demand.
In the water-tube boiler, gases low over water-illed tubes. These water-illed tubes are in turn connected to large containers called drums. 9.4 O&M Best Practices Guide, Release 3.0 O&M Ideas for Major Equipment Types Water-tube boilers are available in
Boiler tube metal corrosion can add to this deposit, but with good boiler operation and proper water treatment practices, tube metal corrosion is not usually significant. The insulating effect of a corrosion product deposit can cause tube metal overheating and subsequent failure.
2011/11/30 · The boiler is supported at the water drum and the water wall lower headers, and there are no rigid connections at any other points in order to allow for thermal expansion. Furnace Closely spaced water wall tubes of 76.2mm outside diameter, form the membrane walls at the side, roof, except for burner opening, rear, and front of the furnace.

Treated warm water should be used. The boiler should be vented to permit air to escape. Ø Check the water level in the gauge glass (mid point) and all the gauge glass valves are open. Ø Test true water level by opening the test cocks, starting with the uppermost.
