Our high velocity Patented Linear Cleaning method is the only solution to provide a full online cleaning service without the need to shut down or stop.
Using this method, not only are the blockages in the gas lanes cleared, but thermal efficiency can be increased by up to 110% – this means greater throughput and increased revenue for the plant.
The shockwave is precise, with just enough energy to dislodge and break up ash deposits, without affecting the plant’s integrity. Due to the targeted manner of the process the complete area or tube bundle can be cleaned, enabling OCT to offer performance guarantees should the client require this.
This method offers guaranteed results, unlike any other service available, largely because of the velocity of shockwaves administered.
The velocity of the shockwaves administered by this method sets us apart from the competition as our Patented Linear system produces a shockwave at a velocity of around 7000 metres/second – greater than anything offered by our competitors.
A greater velocity shockwave makes for a much more effective clean as the ash is dislodged and broken into smaller pieces which are easily cleared.
Slower velocity shockwaves, e.g. those from a gas explosion, can lead to larger deposits being stuck in tube bundles, which can then lead to a rapid blocking of boilers as well as the ash conveyor system having more blockages.
So, using PLC, plant performance can be maintained without any impact from fouling or blockages. This enables plants to extend running periods to up to two years, reducing maintenance costs and increasing availability. High temperature corrosion can also be reduced by maintaining lower flue gas temperatures at the level of the superheaters.
