Boiler Maintenance and Boiler Service Tips

The acceptable level of alkalinity in a boiler depends largely upon the pressure that the boiler will be operating at. In a low pressure boiler, this level should not exceed 700 ppm. If the alkalinity level exceeds 700 ppm it may result in a breakdown of the bicarbonate producing carbonate and liberate free carbon dioxide with the steam.

Fire-tube boiler - Wikipedia

In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam.
