Pre-Startup Chemical Cleaning of Steam Boilers

As part of the initial commissioning of steam boilers at power plants, it is standard practice to perform a chemical cleaning process on the steam-conducting surfaces before their first use. Typically, the pre-operational chemical cleaning process involves flushing, chemical cleaning, and passivation of the surfaces.

Objectives of the Cleaning Process:

Removal of scale from the steam transfer surfaces.
Elimination of grease, oil, corrosion, salts, organic deposits, and any foreign particles.
Achieving completely clean surfaces to ensure the production of clean steam.
Preventing breakdowns and production interruptions and maintaining the long-term integrity of the boiler.

Requirements for a Company Performing Steam Boiler Chemical Cleaning:

Extensive experience and expertise in cleaning large steam boilers (50 tons of steam per hour or more).
Proper equipment for chemical cleaning, including high-capacity pumps and chemical-resistant piping.
Appropriate safety equipment for workers.
Ability to perform monitoring and control throughout the cleaning process.
Valid hazardous materials permits from the Ministry of Environmental Protection.
Authorization to transport hazardous substances.

With over 40 years of experience and hundreds of complex chemical cleanings performed in power plants and leading industrial facilities in Israel, Laor Engineering is the leading company in Israel for pre-operational chemical cleaning of steam boilers.

Pre-Operational Chemical Cleaning of Steam Boilers in Israel

Pre-Operational Chemical Cleaning

Any type of dirt disrupts and interferes with the proper operation of various systems. Those working in industry know that before operating a new facility, residues of dirt, grease, and objects that are not part of the system must be removed. Using a system that has not undergone a pre-operational cleaning process can cause significant damage to the system's sub-assemblies.
Pre-operational chemical cleaning is required to test the performance of new systems and maintain maximum output. Laor Engineering Ltd. performs chemical cleaning in process industry facilities, desalination plants, petrochemical industries, power stations, production plant machinery, institutions, hotels, and more. Every cleaning job, large or small, is carried out under the supervision of company engineers. Laor Engineering Ltd. is experienced in performing precise chemical cleaning to prepare new systems for operation.

How is Pre-Operational Chemical Cleaning Performed?

Chemical cleaning begins with an inspection of the system before initial operation, deciding on the washing process, and continues with the precise selection of chemical solutions and determining the most effective execution method. Pre-operational chemical cleaning must be carried out while maintaining a safe working environment and laboratory monitoring of the solution composition.
Emphasis must be placed on treating effluents after cleaning is complete; additionally, the final removal of all deposits requires hydrodynamic washing. Laor Engineering Ltd. clients can rest assured knowing that the entire job—from start to finish—is performed by the best professionals. The results of the chemical cleaning will be reflected in improved system output, energy savings, and extending the lifespan of the machinery.

Chemical Cleaning Before Rinsing for Cooling Systems

If you regularly operate cooling or air conditioning systems, you are certainly aware of the importance of the condenser. Its periodic maintenance is vital for maintaining stable system output, and adhering to this will ensure cooling capacity according to optimal performance.
When heat transfer surfaces are not clean, it causes high head pressure and a decrease in output. The effectiveness of a pre-operational chemical cleaning is measured by the time interval between it and the next cleaning, and professional chemical cleaning increases the interval between cleaning and maintenance work.

Preparations for Chemical Cleaning

Chemical cleaning is usually performed using inhibited acid, where precise selection of the correct acid (acid concentration and dosage of inhibitor) must be ensured. It is important to monitor the chemical reaction during cleaning using a field laboratory and analytical tools.
Furthermore, before starting the wash, we will verify that all passages are open for the proper flow of the solution. Interested in more details? Do you have questions about chemical washes? Call Laor Engineering now and discover a professional, skilled, patient, and dedicated team.
