O desafio
Big amounts of steam are needed for instance to heat up different processes, with demineralized water attacking boiler surfaces at high temperatures, causing corrosion. Rust particles are transported through the system in the steam, so the corrosion is not limited to one area. This resulted in material abrasion throughout the whole system, reducing the life time of the boiler and the piping system.
A solução Merus
Installed one Merus Ring at the feed pipe in front of the boiler. No changes were made to existing water treatment or corrosion inhibitor dosing during the trial period.
Resultados
→In just a few weeks the iron content in the steam diminished and stabilized at a very low level. During yearly inspection, parts of the surface in the boiler where black due to saturated iron oxide and only few red spots where left compared to the previous inspection. The customer eliminated chemical treatment costs and service costs for the dosing system. No iron was found in the steam so far.
