An effective internal boiler treatment chemicals programme involves the addition of chemicals to the feed water, boiler water, and steam. Product code Composition Comments BV34 Polymer and phosphate based formulation For use as a scale and sludge
Get a QuoteMulti-Wet Multitreat-460 is designed to scavenge dissolved oxygen from feed water to protect boilers, as residual dissolved oxygen in the boiler promotes pitting-type corrosion that is a particularly problematic form of corrosion. If left unchecked, the propagation of the pitting ultimately leads to tube failure.

The method combines classical CFD techniques, which are used to simulate the gas phase, with a set of Eulerian variables defined to model the solid phase and Lagrangian trajectories that model the particle drop.
