Multi-Wet Multitreat-460 Boiler Water Oxygen Scavenger | Australia

Multi-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.

Numerical simulation of the combustion process of a pellet-drop-feed boiler …

2016/11/15 · Abstract. This paper presents a transient model for the simulation of biomass combustion in a fixed bed boiler fed through particle drop. 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.

Boiler Water Oxygen Scavengers - Sulphite, Tannin, DEHA, Carbohydrazide

Also, inorganic oxygen scavengers tend to be temperature dependent and so the lower the boiler feed water temperature the more chemical you need to add. An example of an inorganic oxygen scavenger is sulphite, whereas examples of organic oxygen scavengers are …
