Fuel Additives for Coal-Operated Boilers in Power Plants Improved efficiency . and reduced slagging and corrosion. through SENTROJET chemical injection . into coal-fired boiler or furnace. SENTRO TECHNOLOGIES USA, LLC provides a simple, flexible and cost-effective solutionView More
Certain coals tend to form slag and sintered deposits in the combustion chamber of the boiler. These slagging effects lead to a reduction in efficiency of the plant and eventually the plant needs to be shut down for cleaning in short intervals. PentoMag 2550 contains chemicals that increase the fusion temperature of metals contained in coal ash, thus preventing that ash can stick to the boiler walls.View More
Efficient Fuel Additives (EFA) is a cost effective provider of fuel additive products and combustion consulting services for coal fired boilers in utility and industrial applications. We specialize in addressing issues of slagging and fouling by application of a brucite based magnesium hydroxide additive to …View More
A boiler fuel coal additive is composed of the following raw materials in parts by weight: 40 parts of calcium carbonate, 30 parts of magnesium sulfate, 10 parts of manganese oxide, 10 parts ofView More
Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).View More
PentoMag® 2550 is a modern coal additive serving to prevent coal slagging (fouling). Term “slagging” is understood as formation of hard, sticky deposits covering evaporator and superheater heat exchange tubes inside the furnace. Slagging Usually the slagging starts on the firebox tubes or around the burners, then, once a first layer has formed,View More
CORRELATING THE SLAGGING OF A UTILITY BOILER WITH COAL CHARACTERISTICS Rod Hatt Coal Combustion, Inc. Versailles, KY 859-873-0188 ABSTRACT This paper will describe how a utility was able to correlate intermittent slagging problems a boiler was experiencing with coal ash chemistry. The coal ash fusion temperatures alone were not sufficient to beView More
A familiar application example is P&P mill boilers. Gas turbines are driven by air instead of steam and are used to drive electric generators. The air is mixed with fuel and ignited internally to produce a high temperature and pressure gas. Heavy fuel oil and coal contain significant amounts of sulfur (S).View More
The Effectiveness of Magnesium Oxide-Based Additives in Mitigating Fouling Problems in Kraft Recovery Boilers Liming Zhao Master of Applied Science Department of Chemical Engineering and Applied Chemistry University of Toronto 2011 ABSTRACT Magnesium oxide-based additives have been used in kraft recovery boilers to minimize depositView More
The additive comprises of a combustion catalyst for improving combustion efficiency of the coal which therefore will facilitate oxygen diffusing to internal regions of the coal and reducing the amount of surplus air externally of the coal.View More
CoalTreat ® CoalTreat® is EES’ fuel chemistry innovation that has proven to be highly effective in mitigating problems attributed to furnace slagging and heat transfer surface fouling in coal-fired utility and industrial boilers.View More

Additives for the Power Generation Industry Bell Performance has been serving the power generation industry since 1952 when Robert J. Bell formulated the first version of his Atom-Ix (also called ATX) multi-function treatment for fuel oil.View More
Our pulverized coal boilers currently allow for ramp rate as fast as 6% per minute and down to 20% for hard coal and 35% for lignite based on BMCR. Contact GE Power for more information on the use of boilers in steam power plants. With GE’s boilers, our customers can burn a wide spectrum of fuels, from high-rank coals to low-rank coal wastesView More
Jul 17, 2017 · Clinkers occur in small stoves used for heating a home and in giant commercial/industrial boilers. Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers to be miserable stuff. Video of the DayView More
The resulting product (coal slurry) is then prepared for intermediate storage or transport. Large particle coal-water slurry fuel can be used to produce steam in boilers. Smaller (under 80 micrometer) particle coal-water slurry fuel can be used in diesel engines with or without co-fuels.View More
