The Industrial Boiler Maintenance Checklist Routine boiler maintenance is strongly recommended and can result in operational efficiencies, cost savings and safer work conditions for your company. Unfortunately, many companies are reactive and wait for something to malfunction before attending to their boilers.
If deposits are found to be forming in the boiler tubes, the boiler should be chemically cleaned. It is advisable to consult a company of cleaning specialists who will examine the boiler deposits and treat the boiler accordingly. After chemical treatment the boiler should be blown-down at least twice a day for approximately one week.

Boiler Alkali boil out is carried out to remove material such as lubricants, oil and rust. During manufacturing seamless steel tubes, mill scales are bound to be formed, and some of these can remain inside. During fabrication and erection of the pressure parts, some amount of oil and lubricants can also. get into the tube
Chemical cleaning of smaller boilers is not usually done because: Of the small surface area that the chemical contacts. Of the thin boiler metal. They cannot adequately support the high density chemicals. It is impossible to achieve adequate chemical circulation. The cost is not justified.

Evaluation of Boiler and Heat Recovery Steam Generator Chemical Cleaning Waste Treatment Options. Chemical cleanings are performed to remove deposits in boilers and evaporators in heat recovery steam generators in fossil power plants. This report examines potential treatment techniques for processing wastes generated during chemical cleaning.
Mineral deposits or "scaling" can form on the boiler's waterside inhibiting water flow and heat transfer. Scale is removed through either mechanical or chemical cleaning methods. Mechanical cleaning removes scale with the use of tools like scrapers, brushes, or sand blasters. Chemical scale removal uses acids or other liquid descaler to dissolve the minerals through a chemical reaction
Residential steam boiler maintenance, operation, and chemicals. by Dr. David Zatz. If you have a steam boiler in your house, chances are it's a great big mystery to you. Most homeowners don't seem to keep the owner's manual, which can be quite vague anyway. "Civilians" are not supposed to service the boiler, plumbers are.
A. Latest boiler chemical cleaning techniques is the use of inhibited EDTA ammoniated at around 140 °C and at a conc'n of around 4 - 5 % with oxygen scavengers. This has been successfully used in many of the new boilers erected.
the efficiency of the steam boiler becomes too low or when there is a possibility of blockages and leaks, the decision is often made to clean the water side of the boiler chemically. An inspection is carried out prior to chemical cleaning. This is usually done by sawing through a number of pipes at the point in the boiler pipes

High pressure boilers are designed to produce steam at a specified quality. The quality of steam is very important as otherwise tube failures can happen in boiler and the turbine blades can get damaged causing large availability loss. The pre-commissioning cleaning involves Alkali boil out to remove any oily materials, Acid Cleaning to clean up mill scales and Steam blowing to clean
systems. Chemical treatment of hot water heating boilers is discussed in this section and also in chapter 4 (cooling water). This chapter is organized by chemical treatment (oxygen scavengers, internal treatments, condensate treatment, etc.). Then the treatments are classified by application to boilers in the pressure groupings above.
