Biomass is used as fuel in boiler in form of pellets and briquette developed from organic materials such as scrap lumber forest debris certain crop waste manure and some other organic waste residue. With a constant supply of waste from construction and demolition activities wood not used in papermaking and municipal solid waste this renewable and sustainable source of energy production can continue indefinitely. Our Biomass Additive is a free-flowing powder treatment designed primarily as combustion catalyst for Biomass which helps to reduce loss due to unburnt fuel 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. It also softens the hard clinker and reducing the tendency of hard clinker formation thus helps in reducing the boiler maintenance provide ease in cleaning and increase the boiler availability for long term operation. It promotes smoke free combustion at lower excess air levels resulting in improved fuel economy.
