Fireside Chemicals for Boilers – Clinker, Soot & Corrosion Control
If your boiler crew is breaking clinker off the grate every few days, you already know what fireside problems cost. Steam pressure drops. The stack runs hotter than it should, fuel consumption creeps up, and sooner or later the boiler comes down for a cleaning nobody planned for.
Aries fireside chemicals are added to the fuel or the furnace to deal with these problems where they start. We make grades for coal, biomass and oil-fired boilers as well as thermic fluid heaters, and supply them from Vadodara to plants across India. They sit alongside the rest of our water treatment chemicals, so one supplier can look after your whole boiler.

What Are Fireside Chemicals?
Every boiler has two sides. The water side is everything inside the tubes and drum: feed water, steam, and the scale and corrosion that come with them. Our boiler water treatment chemicals handle that side.
The fire side is where the fuel burns. Flame, flue gas, ash and soot, plus the deposits they leave on the grate, furnace walls and the outside of the tubes. Fireside chemicals treat this side. You will also hear them called fireside additives, fuel additives or anti-clinker chemicals. They change how the fuel burns and how its ash behaves, so less of it sticks to the surfaces that need to stay clean.
Here is what we see a lot. A plant treats its boiler water carefully, tests it every shift, and ignores the fire side until clinker turns into a weekly fight. Both sides affect efficiency. Tubes that are clean on the inside still lose heat if they are coated in soot on the outside.
Fireside Problems We Help You Fix
Clinker forms when ash gets hot enough to soften and fuse into hard lumps. Fuels with a low ash fusion temperature are the usual cause, and in Gujarat that often means rice husk, groundnut shell, bagasse and some imported coals. Once clinker builds up it blocks air through the grate, the fuel burns unevenly, and operators end up breaking it out by hand.
Soot is unburnt carbon that settles on tube surfaces. It is a very good insulator, which is the last thing you want on a heat transfer surface. Heat that should go into the water goes up the chimney instead. A flue gas exit temperature that keeps rising week after week is usually the first sign.
Oil-fired boilers have a different problem. Vanadium and sodium in furnace oil form a low-melting ash that attacks superheater and furnace tubes at high temperature. At the cold end, sulphur in the fuel turns into acid that condenses in the economiser and air preheater whenever metal temperatures fall below the acid dew point.
Every cleaning shutdown means lost steam, extra labour and a production plan built around the boiler instead of the other way round. When the gap between cleanings keeps getting shorter, the fire side needs attention.
How Aries Fireside Chemicals Work
Our fireside chemicals are blended formulations, and each grade is built around the fuel it is meant for. The way they work comes down to a few things.
Better burnout. Combustion catalysts and oxygen-releasing agents lower the temperature at which carbon burns off. More of the fuel burns completely, so less soot and unburnt carbon are left behind.
Ash that stays loose. The formulation raises the temperature at which ash softens. Instead of melting into hard, glassy clinker, the ash stays powdery and falls through the grate or leaves with normal soot blowing and ash handling.
Softer old deposits. With regular dosing, existing soot and slag layers turn brittle and start breaking away. Heat transfer comes back gradually, without a full shutdown to scrape the tubes.
For oil-fired boilers, the additive also combines with vanadium and sulfur compounds so they form an ash with a higher melting point that does far less damage to the tubes.
Our Fireside Chemical Range
Different fuels need different chemistry. A grade that works well in a coal boiler will not do the same job in a furnace oil unit, so we keep the range split by fuel.
Grade | Suited for | Form | How it is dosed |
|---|---|---|---|
Solid fuel fireside chemical | Coal, lignite and pet coke fired boilers | Liquid | Sprayed on the fuel at the conveyor or bunker |
Biomass fireside additive | Rice husk, bagasse, wood chips, groundnut shell and briquette fired boilers | Liquid | Sprayed on the fuel before it is fed to the furnace |
Fuel oil additive | Furnace oil, LDO and LSHS fired boilers and thermic fluid heaters | Liquid, oil-soluble | Dosed into the day tank or fuel line |
Soot remover | Any fuel-fired boiler with heavy soot on the tubes | Powder or liquid | Added into the furnace while firing |
Not sure which one you need? Send us your fuel type and a photo of the deposits. That is usually enough for a first recommendation.
What You Can Expect
Results depend on fuel quality, the condition of the boiler and how consistently the chemical is dosed. We would rather measure them at your site than promise a number on a website.
Industries and Boilers We Serve
Most of our fireside customers burn solid fuel. Sugar mills firing bagasse are a large group, and we often supply them alongside our sugar processing chemicals. Textile and dyeing units, paper mills, rice mills, food processing plants and chemical plants across Gujarat make up much of the rest.
On the oil side, we work with plants firing furnace oil and LSHS, including refineries that also use our refinery and oil field chemicals. Many of these sites run cooling towers as well, and our cooling tower chemicals cover that system.
The range is used in fire-tube and water-tube boilers, FBC and AFBC units, travelling-grate and fixed-grate boilers, and thermic fluid heaters.
Dosing and Application
How the chemical goes in depends on the fuel. For coal and biomass, the liquid is sprayed onto the fuel at the conveyor, bunker or feeder, so it spreads through the fuel before reaching the furnace. For oil-fired boilers, the additive is dosed into the day tank or fuel line, where it mixes with the oil.
You will not find a fixed dose on this page, and we would be careful with any supplier who gives one without asking about your fuel. The right quantity depends on ash content, fuel quality, boiler load and how much deposit is already there. We start with a dose based on your fuel details, then adjust it after watching the boiler for a few weeks.
Handle the product with gloves and safety goggles, and store it in closed containers at room temperature, away from direct heat. We send the MSDS with every supply, and you can ask for it before ordering.
Why Plants Choose Aries Chemtech
We are an ISO 9001:2015 certified manufacturer of water treatment and speciality chemicals, based in Vadodara and supplying plants across India.
One supplier for both sides of the boiler. We already supply oxygen scavenger, boiler descaling chemical and sludge conditioner for the water side. That lets us look at your boiler as one system. If the stack temperature is climbing, we can check whether the cause is soot outside the tubes or scale inside them, instead of guessing.
Support after the sale. Our team can visit the site, help set up dosing, and review the results with your operators. If the first dose is not right, we change it.

Fireside chemicals treat the combustion side of a boiler. They help fuel burn more completely, keep ash from fusing into clinker and loosen soot on tube surfaces. Plants use them to cut cleaning shutdowns, keep heat transfer up and control fuel consumption in coal, biomass and oil-fired boilers.
Water-side chemicals treat the feed water and steam inside the tubes to control scale, corrosion and dissolved oxygen. Fireside chemicals treat the fuel and flue gas outside the tubes to control clinker, soot and fireside corrosion. Most boilers benefit from both, since deposits on either side reduce heat transfer.
They change how ash behaves at furnace temperature. Instead of softening and fusing into hard lumps, the ash stays loose and powdery, so it drops through the grate or leaves with normal ash handling. Better combustion also leaves less unburnt carbon to bind the ash together.
Yes. Biomass fuels such as rice husk, bagasse and groundnut shell often have a low ash fusion temperature, which makes them prone to clinker. We supply a biomass grade made for these fuels. It is sprayed on the fuel before it enters the furnace.
Yes. Our fuel oil additive is oil-soluble and is dosed into the day tank or fuel line. It improves atomised combustion and helps control vanadium ash attack at the hot end and acid corrosion in the economiser and air preheater.
For coal and biomass, the liquid is sprayed onto the fuel at the conveyor, bunker or feeder. For oil, it is mixed into the fuel through the day tank or a dosing pump. The quantity depends on fuel quality, ash content and boiler load, so we set the starting dose after reviewing your fuel details.
It depends on how dirty the fire side is to begin with, the fuel and how consistently the chemical is dosed. A boiler with heavy soot and clinker usually shows a bigger change than one that is already clean. We prefer to track stack temperature and fuel per tonne of steam at your site rather than quote a fixed figure.
