At a power station in Scotland, as part of the flue gas desulphurisation project, there are one thousand metres of 300mm Ø aeration pipes lying across a river bed.
The aeration pipes lay dormant for approximately six months. During this time, large quantities of silt and mud had accumulated within the pipes, blocking them and preventing air passing through the pipes.
Using a high-pressure water jet washer, EDS broke up the mud and silt, and pumped it downstream of the aeration pipes, using a diesel-powered water pump lowered into the pipes.
This process took almost three weeks with the aeration system working as designed. Reduced pressure and heat build-up were the result of the companys work.
