Turbine cleaning refers to the cleaning of gas, steam, and wind turbine parts to improve performance and minimize downtime. Turbine cleaning has different types, including:
Turbine gas cleaning
Gas turbines are used to generate power and are cleaned to improve efficiency and reliability. The gas turbine blades are often cleaned because they are prone to deposits and corrosion, which can result in reduced efficiency and damage in the long run. There are different cleaning methods, including the dry and wet methods. The former uses non-abrasive media like carbon or plastic to remove deposits, while the latter employs water or chemical solutions to eliminate deposits without damaging the underlying substrate.
Steam turbine cleaning
Steam turbines are used in industries and power plants to convert steam into mechanical energy, which is then used to generate electricity. However, over time, the steam turbine blades may get contaminated, which can affect the efficiency of the turbines. Condensate impurities, particulate matter, and chemical carryover are some contaminants that affect the performance of steam turbines. The cleaning methods used include online cleaning, which is done while the turbine is operational, and offline cleaning, which is done when the turbine is not operational.
Wind turbine blade cleaning
Wind turbines are used to convert wind energy into electrical energy. Wind turbine cleaning is important since contaminants like dust, ice, and biological deposits can reduce energy output by interfering with aerodynamics. There are different cleaning methods, including the dry method that uses brushes and towels and the wet method that uses water and cleaning solutions.
Frequency
How often a cleaning is performed depends on the kind of work a turbine does, how clean its environment is, and how much dirt builds up on it. Wind turbines in places with high dirt levels like farms or cities will need cleaning more often than those in less dirty areas. Similarly, if a gas or steam turbine is used for heavy-duty tasks, it will require cleaning more frequently than one used for lighter work. Cleaning schedules should also be flexible to allow for inspections and corrective actions whenever required.
Inspection
Before any cleaning happens, a thorough inspection is done first. This checks for damages, tells how much dirt or dust there is, and sees if any parts of the turbine need special attention or care. The inspection uses tools such as visual checks, drones, or specialized equipment to assess the turbine's condition and safety. The inspection results guide the cleaning process by determining what areas to focus on and what cleaning methods to apply.
Safety precautions
Taking care of the safety of workers and the turbine itself is very important during cleaning. Workers have to follow all safety rules, wear the right protective gear, and use safe cleaning methods. Safety guidelines are adhered to, and the right equipment is used to prevent accidents, injuries, or damages during the cleaning process. Turbines have delicate parts that can be damaged by strong cleaners or rough handling. Therefore, the right cleaning agents and methods are chosen to protect the equipment from harm.
Environmental considerations
Environmental concerns are key when cleaning turbines. Only cleaners and methods that are good for the environment are used. Waste from the cleaning process is handled properly and safely disposed of, following environmental laws and rules. Care is taken not to harm the surroundings, such as plants, animals, and water sources, during cleaning. This protects the environment and maintains the turbine's operation in harmony with nature.
When purchasing gas turbine parts and accessories, buyers need to understand their market and customer needs. They should conduct research to identify product trends and popular demand in their target customers.
Decide if the products will be for resale or for use in the business. If it's for resale, focus on products that will attract customers. While at it, factor in the storage space and the budget. Cleaning tools and accessories come in different sizes, and some may require a lot of storage space. They also have varying price points.
Check the quality of products to ensure they meet the customers' expectations. Quality products may come with a higher price point but offer better value. They also have a longer shelf life, which reduces the need for frequent replacement. Look for products with warranties as an assurance of quality.
Gas turbines are used in various industries, including power generation, oil and gas, aviation, and manufacturing. Therefore, when choosing cleaning products, opt for those that can serve different turbines used in various industries. However, some customers may prefer specific brands or products due to their effectiveness. Therefore, it might be a good idea to source for particular brands that loyal customers use.

When choosing turbine cleaning products, prioritize the safety of the end users. The products shouldn't have harmful chemicals that can endanger the users' lives. Also, consider the environmental impact of the products. They should adhere to environmental regulations and standards.
Cleaning and maintaining gas turbines are vital for optimal performance. While professionals are equipped to handle such tasks, there are ways to undertake simple cleaning procedures at home.
Before any cleaning process, it is important to read and understand the gas turbine operation and maintenance manual. This provides guidance on what to expect and the dos and don'ts during cleaning and maintenance.
Below are some basic steps to undertake when cleaning gas turbines:
Visual Inspection
Always do a visual inspection before and after any cleaning activity. This ensures the safety of the equipment and the personnel involved. Inspect for any damaged components that may require expert attention during cleaning.
Prepare the Cleaning Solution
Follow the manufacturer's instructions to prepare the cleaning solution. This is the only way to use the right concentration and avoid any adverse effects on the turbine components.
Access the Turbine Components
Accessing the turbine parts requires following safety procedures such as locking out/tagging out (LOTO) and allowing the turbine to cool down. This mitigates risks of accidents and injuries.
Wet Wash
For gas turbines with water-washable components, do a wet wash using the prepared cleaning solution. Using soft brushes or cloths, gently clean the turbine blades and other accessible parts to remove deposits and contaminants. Rinse thoroughly to remove any residue.
Dry Wash
For gas turbines where wet washing is not applicable, adhere to dry washing procedures. Use lint-free cloths or wipes soaked in the recommended cleaning solvent. Mechanical means such as vacuuming can also be utilized to minimize the risk of damaging delicate components.
Inspect and Replace
During the cleaning process, always inspect filters, seals, and other components for wear or damage. Replace any worn-out parts to maintain the turbine's efficiency and reliability.
Final Inspection
After cleaning and reassembly, perform a final inspection to ensure all components are in place and functioning correctly. Check for leaks or abnormal noises before restarting the turbine.
Documentation
Document all cleaning activities, inspections, and maintenance work performed on the gas turbine. This is important for future reference and compliance with maintenance schedules.
Training and Safety Precautions
Ensure personnel involved in turbine cleaning are adequately trained in safety procedures, handling cleaning agents, and working with turbine components.
By following these steps, a gas turbine can be maintained and cleaned in good condition, enhancing durability and reliability. Remember, for any complex cleaning procedures or repairs, always consult a qualified technician or refer to the manufacturer's guidelines.
