The efficiency of the Air-Cooled equipment’s gets affected over a period due to deposition of insects, birds dropping, coke fines, Cement particles, coal dust and other foreign matter and for the efficient working of the coolers, the same must be removed on a regular basis as they restrict air flow. To achieve the same, we must do the cleaning process. In this, process primarily uses foam ridden solvents, which has high penetrating capacity combined with property to reduce the surface tension and ensuring consistent quality of Foam with very half-life period. This is an important factor in Foam Cleaning technique.The Foam ridden solvents can soak for a period to permit penetration thereby reducing the adherence of the scale to the surface. Later, the surface is laced with abundant quantity of water at low pressure to flush out the dislodged scale. In our experience and trial studies, we found that this technique is much suitable for cleaning of the fins where deposits get trapped in inaccessible intricate areas.
