Oxygen leak detection in steam and condensate systems
Air leaks normally cause rapidly advancing corrosion at the forward end of paper and board machines, where cylinders and tanks are under a constant negative pressure. As a result steam and condensate systems are exposed to corrosion and water leaks.
The condensate carries oxygen and carbon dioxide to power plants. This leads to increased consumption of oxygen scavangers and alkalizing chemicals as well as to energy loss.
Oxygen leaks are located by means of a gaseous leak detection agent and the number of leaks is measured. The results are documented and reported to the customer. The customer also receives recommendations for mesures to solve the problems.
