Chemical Cleaning of Boiler System (Practical Guide from start to Finish)
A practical guide on chemical cleaning processes for boilers from start to finish
Overview
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.
Most boiler operators have limited experience, due to the fact that chemical cleaning does not happen often (usually 1-2 in the lifetime of a boiler). Chemical cleaning is a nasty process, filling your boiler with hot acid, so you better make sure it is done properly.
A practical guide on chemical cleaning processes for boilers from start to finish: These 2 half-days Online Virtual instructor-led Training (VILT) will focus on 2 parts: the Chemical cleaning best practices and decision process (2) Chemical handling. The virtual training begins with how and determining When to Clean, selecting a chemical cleaning service company, good preparation and understanding what solvent to use to clean the boiler (advantages and the disadvantages of each solvent).
This will follow by monitoring and evaluation of result during and after the process such as Maintaining selected cleaning parameters (temperature, circulation), progress of cleaning (e.g. iron content in cleaning fluid) and preservation of base metal (inhibitor effectiveness).
The instructor will further discuss “special cleaning processes” such as out of the ordinary situations, where standard operating procedures cannot be applied just like that. Further examples where extra care had to be taken to prevent damages. Lastly, Environmental effects of spent cleaning fluid, concerns/permitting from authorities and waste handling options.
The course focusses to all kinds of water/steam boiler systems that are made of (mostly) carbon steel and copper.
These 2 days virtual training will provide boiler operator more about insight in the process and that such insight increases the ability to prepare, select the proper supplier and cleaning processes and have the ability to validate the process and results. This will be augmented by case studies.
