Fireside Boiler Treatment | ChemTreat, Inc.

Boiler design has proven to be a very important consideration in the determination of magnesium additive levels. The addition of aluminum to magnesium-based additives reduces magnesium sulfate deposition. The greatest need for fuel additives to control deposition is in boilers previously used to fire other fuels, such as natural gas or coal.

Comparing fuel additives for fireside corrosion inhibition

Sep 01, 2021 · 1. Introduction. Fireside corrosion of superheater and reheater tubes is a major issue within pulverised fuel boilers that can lead to downtime and the need to replace the tubes [].In order to reduce CO 2 emissions, biomass is likely to become the solid fuel of choice in pulverised fuel systems. This will exacerbate fireside corrosion due to the increased alkali metal and chlorine content in
