TRANSCRIPT
Avoiding boiler cleAning-relAted incidents And costsBoiler cleaning is recommended to prevent corrosion and
ensure the required thermal and physical characteristics of
the boiler equipment. However, if not carried out properly,
the cleaning process induces a high risk of leaks. Laborelec
helps power plants assess the need for chemical cleaning,
provides advice on an efficient and safe procedure, and
witnesses cleaning operations.
increAsing AvAilAbility, reducing costsOur expert support for boiler cleaning provides power plants
with the following benefits:
> optimizing cleaning efficiency We provide advice on selecting the appropriate offline
cleaning procedures and processes in order to optimize
cleaning efficiency.
> Avoiding operation and maintenance costs Based on metallographic analysis and iron removal lab tests,
we first evaluate whether chemical cleaning is needed or
not. Without the appropriate boiler cleaning, there is a 10%
probability to have an incident costing up to 800,000 euros
(figure based on validated estimate of the 2011 Chemistry
Platform) during the next ten years of operation. If cleaning is
necessary, it is indispensible that it occurs correctly. Otherwise,
the cleaning itself can give rise to corrosion pitting leading to
boiler tube failures. Important breaches in the process can
induce the replacement of the whole evaporator.
> increasing availability The goal of the technical support before and witnessing
during boiler cleaning is to avoid cleaning-related incidents.
We make sure the process is carried out in due time and
according to in-house and international best practices in
order to avoid unforeseen downtime.
> increasing safety and reducing environmental risk Our experts inform the plant about the environmental impact
of boiler cleaning. By witnessing the cleaning operations, we
help avoid errors that could affect the safety of the boiler’s
immediate environment.

Assisting boiler cleaning from first assessment to final quality check
laborelec helps prepare the cleaning procedure, analyzes the proposal of specialist cleaning companies, witnesses onsite operations, provides assistance in case of issues, and verifies the quality of the cleaning process after completion.
before - PrePAring the cleAning ProcessFirst, we carry out a short audit to assess the need for
chemical cleaning. Next, when cleaning is desirable, we
perform laboratory tests on boiler material samples in order
to prepare the cleaning procedure. We also assist in issuing a
call for tender to specialist companies and in reviewing their
technical documentation. Our experts verify the different
procedures planned by the contractor: chemicals injected,
nitrogen circulation, chemical analysis results, temperature
control on the whole boiler, duration per step, etc.
during - Witnessing the cleAning ProcessDuring the boiler cleaning operations, Laborelec carries
out a permanent follow-up on site. Our experts monitor
the works from the beginning of the acid cleaning until
the final passivating step. During the process, we provide
improvements to ensure an optimal cleaning.
After - vAlidAting the cleAning ProcessUpon completion of the cleaning operations, we carry out
visual checks and collect samples from the boiler material
and analyze them to assess whether the operation was
successful.
