Cleaning Robot Lance Tackles Hard Scale for Power Company


Tube Tech has been providing specialist cleaning for a major UK power company for many years. Our understanding of the asset and ability clean hard to reach sections of tube means we can deliver enhanced cleaning that will enable the plant to run at full generation.

The Challenge

Fouling associated with the effects of combustion at this UK power plant included a reduction in air flow, heat transfer and an increase in pressure drop, resulting in reduction of output.


The Solution

Manually operated lances from the Tube Tech ‘Convection Section’ Cleaning Robot were able to reach between the finned tubes and remove hard scale deep into the coil. A team of three operatives spent nine days on site working on two assets at the power plant.

Tube Tech Comment

Removing fouling from deep between the economiser tubes enables the plant to regain full heat transfer efficiency and a lower pressure drop, which in turn brings back full generation.
