  • Publication number: 20090071068
    Abstract: A composition and method for creosote control in firebox flues burning solid fuels combines hydrophobic metal additives with a fire accelerant. According to certain embodiments, the compositions may inhibit corrosion of metal flues in addition to creosote deposits. When the metal salts are added to an accelerant at effective concentrations, the combination delivers the metal catalyst to the lining of the exhaust system upon combustion. As such, the metals are conveniently and efficiently transported up the flue.
