Chemical Cleaning Of Boilers - To Clean or Not To Clean

Chemical cleaning can play an important role in boiler maintenance. Proper chemical cleaning removes deposits from the inside of boiler tubes which improves the boiler heat rate, reduces tube failures and improves the stability of boiler chemistry. However, chemical cleaning is expensive. Vendor costs alone may total $50,000 to $150,000

Cast-Iron Boilers - National Board of Boiler and Pressure

Boilers fired with solid fuel such as coal or wood will be extremely difficult to estimate, since there is no way for the inspector to calculate the cast-iron boiler heating surface. In those cases, the inspector should request the boiler owner/user perform an accumulation test in accordance with HG-512(a), or a maximum burned fuel evaluation

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 …

Boilers - an overview | ScienceDirect Topics

Boilers should run at design loads to achieve proper heat transfer efficiency – operating far from their optimum design results in wasted energy. If soot, slag or scale is allowed to build up on the inside or outside of the boiler tube banks it will act as an insulator causing losses in heat transfer efficiency and the boiler will not operate at its design capacity.
