Boiler Solutions. Aqua Regia Pvt. Ltd. provides customizable boiler water treatment solutions to address common boiler problems such as corrosion, deposition and scaling. Holistic programs are available that combine chemistry, equipment, data analytic, and field services to address these and other problems and thereby drive enhanced operational
The slagging/fouling due to the accession of fireside deposits on the steam boilers decreases boiler efficiency and availability which leads to unexpected shut-downs.
4.7-3 and deposits from mill to mill, there is no truly "typical" deposit composition. For example purposes below, the deposit composition that may be typical for a boiler at an inland mill operating at 28% white liquor sulphidity (on active alkali) and at a relatively hot
1/12/1999 · Estimated ash deposition rates using a deposition model, based on sticking probability, also showed that Al-treated coals will result in less ash deposition on boiler surfaces than raw coal. Mineral additives: Experiments with mineral additives indicated that sodium could also be effectively captured by clay-type minerals, particularly kaolin.
mills still use the additives for fouling control. A systematic study was performed to examine the effect of MgO-based additives on deposit accumulation and removal under controlled laboratory conditions, and to evaluate the additive effect in a kraft recovery boiler
Boiler Water Treatment Even when feedwater chemistry is controlled within ASME, IAPWS, or EPRI guidelines, internal boiler treatment is still necessary to control deposition and corrosion in the high-temperature environment of the steam generator.
9/2/2021 · Fuel Additives Fuel additives such as magnesium and aluminium oxides used to control the high-temperature corrosion problem in boilers. The function of additives had to elevate the melting point of the deposits present in the fuel oil. Thereby deposition of
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.
Boiler water treatment is a type of industrial water treatment concentrating on removal or chemical modification of constituents potentially harmful to the boiler. Different types of treatment are practiced to control alkalinity, prevent scaling, correct pH, control conductivity in the boiler …
CHARACTERISTICS OF WATER-SIDE DEPOSITS IN BOILER TUBES by David P. Kalmanovitch DB Riley, Inc. Worcester, Massachusetts INTRODUCTION The formation of water-side deposits in drum-type utility boilers is a major concern to the heat transfer
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.
Special additives modify slag and improve coal combustion.Because of improved combustion, fouling of heat exchange surfaces is reduced. Fireside treatment chemicals are also used to condition the already formed deposits in boilers during operation and prevent further deposition.Such online treatment systems have proved to be very useful for preventive maintenance of boiler.
When the deposition of ash on furnace walls, mainly in the radiant section, in a highly viscous state and forms a liquid layer, it is called slagging. When the deposit is built up by condensed

19/8/2019 · POLYTE®30A boiler decoking agent, It will react in combustion heating after mix with coal. Control coking, deposition and corrosion of fire side by increasing the melting point and looseness of the ash component, and then promote coal combustion, expand combustion volume, increase heat transfer area and improve thermal efficiency.
Various additives can control fireside deposit accumulation in recovery boilers. Results are not conclusive due primarily to the high "ash" content of the block liquor, the high alkali content of
