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.

Mid South's synergistic fuel treatments: Control fireside deposits and corrosion. Increase boiler efficiency and reliability. Improve fuel quality and combustion. Decrease the size of abrasive particles in the fuel, to reduce burner tip erosion while enhancing fuel atomization. FOT 701 is a versatile multi-purpose fuel oil additive.
Fireside boiler treatment is a necessary component for the prevention of fireside slag/deposition from fuel ash components, fireside corrosion, and cold end corrosion. ChemTreat's fuel conditioner products consist primarily of organometallic formulations and help address problems associated with pre-combustion, combustion, and post-combustion.
Reduced pluggage and deposition in the boiler have also led to improved heat transfer rates. The integrated observation camera and sootblower control system (under development) are expected to reduce sootblower steam usage by 30%-35% and improve heat transfer efficiency by 20%.

Dec 01, 2015 · Pulverized halloysite was injected to the furnace of a power boiler. • Halloysite as fireside additive limits the deposits formation in a PC boiler. • Halloysite influences chemical composition of ash. • 6–12% increase of heat transfer was observed during halloysite feeding. • Halloysite improves the ash structure for practical applications.
Dec 01, 2015 · 1. Introduction1.1. Fireside ash deposition. Fireside ash deposition on the heat transfer surfaces is a very complex chemical and physical process which involves a number of steps, such as: ash release, vaporization of mineral matter, formation of ash components and their transformation, transport of the ash particles to the heat transfer surfaces, hit and adhesion to the heat transfer surface
Acceptable additive where discharge waters are required to contain little to no phosphorus. Phosphinocarboxylic Acid (PCA) – Carboxylic homopolymer scale inhibitor. Acts against the precipitation and deposition of Calcium Carbonate, Calcium Sulfate, and other sparingly insoluble salts. Thermally very stable, even in high-pressure boilers.

Feb 01, 2021 · Abstract. The most severe problem in firetube boilers is fouling formation and under deposit corrosion (UDC) on the tube surfaces, leading to water or steam leakage into the fire–side and emergency shutdowns. In this work, fouling propensity and UDC mechanism on the outer surfaces of firetubes of seawater boilers are investigated.
and power generation. Deposition of fly-ash on tube surfaces in the upper furnace of recovery boilers is a persistent problem in many kraft pulp mills. Massive deposit accumulation greatly reduces the boiler thermal efficiency, may create a corrosive environment at the tube surface, and in severe cases, may completely plug the flue
