The primary aim of combustion is to obtain maximum amount of steam from each unit of fuel. But impurities in fuels and operational problems are limitations to achieve maximum output from burned fuel.
The impurities in coal can lead to formation of slag in boiler furnace, can leave the clinkers on the fuel bed and the presence of Sulphur can lead to the cold end corrosion.
It is possible to improve the combustion of fuel and reduce un-burnt carbon in the ash.
A fireside additive plays an important role in complete combustion of fuel along with a control on corrosion deposits, slagging clinker formation, reduction in air borne pollution emission as well as inhibition of fouling.
Our Multipurpose Solid Fuel Additive is a free-flowing powder, designed primarily for treating coal, wood and other solid fuels.
It acts as a combustion catalyst and thereby loss due to unburnt fuel gets minimized, resulting in improved combustion efficiency.
It has an anti–fouling agent that helps to keep heat transfer surfaces clean and thus improves the steam generation for same heat transfer area. Hard clinker is softened and the tendency of hard clinker formation is reduced, thereby helping in reducing boiler maintenance, while providing easy cleaning and also increases the boiler availability for long term operation.
This results in smoke free combustion at lower excess air levels and improved fuel economy.
Start with an initial dosage of 1 kg of additive for 4 ton of coal. After a Month dosage should be adjusted according to the performance of the additive. If smoke persists, increase by 0.5 kg per 4ton of coal for another month. If smoking stops, decrease by 0.5 kg per4ton of coal. To get the best performance of the additive, a regular dosage of the additive with as per the addition of coal is to be maintained.
Standard Packing: 50 KG HDPE.
Method A (For Manual charging of Fuel)
Add the fireside additive by manually charging through Fire Door / Inspection Door Point in furnace. For best results ensure the additive spreads over the maximum area of the solid fuel and covers the complete furnace.
Standard Packing: 50 KG HDPE.
1) keep the Damper opening at minimum level during application.
2) Use soot blowing facility after chemical application.
3) If Force Draft is experienced put off the fan during dosing of chemical.
To be dosed directly into combustion zone once in a day or hourly as a Direct dose.
We have a wide range of Solid Fuel Additive, designed primarily for treating almost all types of solid fuels like coal, wood, bagasse, biomass and other solid fuels.
UNICHEM-Fs 30 is a versatile liquid phase combustion-monitoring chemical/fuel additive for liquid fuel such as furnace oil, LDO, LSHS etc. These products are contains dispersant, anti fouling agent along with advanced combustion catalyst for liquid fuel to improve boiler performance.
Use of heavy fuel oils in industrial furnaces is known to produce a host of corrosion, shoot deposition and environmental related problems. Severe corrosion in hot and cold zones of the furnace and emissions of obnoxious gases, particulates and acid smut to the atmosphere, shoot deposition, poor efficiency, nozzle choking, shoot rain are a few to name which will cost millions by way of forced shut downs and unscheduled maintenance, besides creating environmental pollution. A cost effective solution to mitigate some of the above problems is the use of chemical fuel additives. The effectiveness of chemical additives in heavy oil fired boilers is site specific and requires testing of additive in the boiler under actual operating conditions to optimize the additive regime to obtain the maximum gains.
