It is well known that compressor efficiency plays a vital role in the overall operation and reliability of a plant. As compressors get dirty, even with the most sophisticated inlet air filtration systems, power output is reduced and fuel consumption increases. Even small performance losses result in a significant negative impact on plant efficiency. The maintenance of clean compressors must be an integral part in the operation of any plant. Compressor degradation is very site specific depending on location, environment and type of operational requirements, but all gas turbine compressors require cleaning at some point. AS Energy in alliance with a world approved gas turbine cleaning product manufacturer can execute a cleaning program that meets the Gas turbine OEMs cleaning standard. Based on the client’s immediate request we are able to carry out the following cleaning.
On-line cleaning – Also known as hot washing, this can be carried out quickly, simply and effectively whilst the turbine is working. It allows for the prolongation of the times the turbine is operational, avoiding frequent downtime and ensuring constantly high performance levels. The special composition of our cleaners ensures superior cleaning results, even in the high-temperature area at the back of the compressor.
Off-line cleaning– This method, also known as cold or crank washing, is called for when a turbine’s performance falls below 94% of its potential power due to contamination and allows it to return to close to 100% nominal power.
