FIRESIDE COMBUSTION ADDITIVE
ScaleAwayA271 is a complete formulation for solid fuel treatment based on combustion catalysts, slag modifiers and corrosion inhibitors.
Properties ScaleAwayA271 has been developed for coal fire units equipped with:- - Pulverisers - Spreader Stokers - Cyclone Burners - Chain Grates - Fluidized Bed Systems.
This treatment can also be applied to several other types of solid fuel; peat moss, hog, bark and other combustible residues.
WORKING PRINCIPLE
Combustion Catalyst ScaleAwayA271 contains a highly active combustion catalyst specially formulated to lower the auto ignition temperature of carbon. This temperature can be reduced significantly to enable more complete combustion in the fire box. Slag Modifier ScaleAwayA271 contains alkali earth compounds which are rapidly converted to very active fine particles which combine with low melting slag formed during combustion to make high melting dry compounds that will not adhere to boiler surfaces.
Acid Neutraliser Active components of ScaleAwayA271 oxidised during combustion combine with sulphur trioxide and sulphuric acid to form compounds that are not corrosive to boiler surfaces.
DIRECTIONS FOR USE
ScaleAwayA271 is added continuously or intermittently to the coal handling system prior to the feeder equipment by means of an automatic feed device to ensure proper mixing with the coal.
Dosage rates will depend on the type of fuel burned in the boiler and the severity of the problem. However, a dosage rate between 0.2kgs/ton and 0.4kgs/ton can be advised depending on degree of fouling present and coal quality.
TREATMENT ADVANTAGES
Improve combustion by reducing the amount of carbon in the fly ash up to 60 %.
Reduce slagging of the convection zone, super heater and the amount of fireside deposits.
Reduce draft losses between the fire box and the economizer.
Increase operational time between shut-down.
Decrease of the frequency and duration of load reduction to remove fouling deposits.
Neutralize acid deposits and reduce economizer or air heater corrosion.
Reduce atmospheric pollution and eliminate dry smutting or acid smutting.
Reduce the amount of ash to be treated and hauled away.
Easy to apply with an automatic feeding system.
Non-toxic or harmful treatment with no negative secondary effect on the boiler or the back end equipment.
Ignite Efficiency, Eliminate Slag: Transform Your Boiler Fireside with ScaleAway A271
Every ton of solid fuel that passes through your feeders represents a massive investment—but inefficient combustion and destructive fireside deposits could be quietly stealing your profitability. When coal, biomass, or combustible residues burn incompletely, they leave behind rock-hard slag, choke your system's draft, and unleash highly corrosive acids that destroy your economiser and air heaters.
ScaleAwayA271 Boiler Fireside Combustion Additive is your ultimate solution to heavy fouling and thermal loss. Formulated as a complete, multi-action solid fuel treatment, it integrates advanced combustion catalysts, powerful slag modifiers, and robust corrosion inhibitors into one high-performance package. Whether your facility operates on coal, peat moss, bark, or hog fuel, ScaleAwayA271 unlocks the maximum thermal energy from your fuel while aggressively protecting your downstream equipment.
The ScaleAway A271 Advantage: Unleash Peak Thermal Performance
• Recover Wasted Fuel Energy: Lower the auto-ignition temperature of carbon significantly. This enables an incredibly complete burn in the firebox, slashing unburnt carbon in the fly ash by up to 60%.
• Shatter Slag and Fouling: Stop hammering away at fused deposits. ScaleAwayA271's active alkaline-earth compounds mix with low-melting slag to create high-melting, friable, dry compounds that will not adhere to your boiler tubes or superheaters.
• Halt Cold-End Acid Corrosion: Active components oxidize during combustion to immediately neutralize sulfur trioxide (SO₃) and sulfuric acid (H₂SO₄), eliminating the acid dew-point corrosion that eats away your air heaters and economisers.
• Keep Production Moving: Experience a dramatic reduction in the frequency and duration of painful load reductions or emergency shutdowns for manual fireside cleaning.
• Lighten the Environmental and Waste Burden: Drastically decrease particulate stack emissions while eliminating acid smutting. By burning carbon completely, you reduce the physical volume of ash hauled away and lower the stress on your baghouses, electrostatic precipitators, and scrubbers.
Versatile System Compatibility
Engineered to perform seamlessly across heavy industrial configurations, ScaleAwayA271 delivers exceptional results in coal-fired and solid-fuel units equipped with:
• Pulverisers & Spreader Stokers
• Cyclone Burners & Chain Grates
• Fluidized Bed Systems
Non-toxic or harmful treatment with no negative secondary effect on the boiler or the back end equipment.
