Abstract
A processed solid fuel composition incorporating agents for destroying creosote and soot within flue ducts and chimneys of fireplaces, solid fuel stoves and other heating devices is disclosed, along with a method for its manufacture and a method for its use. The composition is made up of a combination of compressed cellulosic particulate material and a chemical and/or catalytic creosote and soot removing agent, and is molded in the form of a fire log in the preferred embodiment. The composition may be used alone, but is ideally applied to an active fire to treat a chimney flue by combined heating and chemical disaggregation of accumulated creosote and soot deposits.
Claims19
A processed solid fuel composition for destroying creosote in chimney flues comprising:
- a solid particulate combustible cellulosic material (a);
- a creosote-destroying chemical agent (b) chosen from the group consisting of metallic chloride of sodium, potassium, zinc, tin, copper and mixtures thereof;
- and
- relative proportions of (a) and (b) are, by weight, from 50 to 99.9% of (a) and 50 to 00.1% of (b).
The processed solid fuel composition according to claim 3, wherein said log is 6 to 14 inches in length.
The processed solid fuel composition according to claim 7, wherein said agent further includes ammonium phosphate.
A process for manufacturing a processed solid fuel composition for destroying creosote within chimney flues, comprising the steps of:
- admixing a solid particulate combustible cellulosic material (a), and a chemical catalytic agent that disaggregates creosote (b), whereby the relative proportions by weight are 50-99.9% of (a), and 50-00.1% (b) for 100 parts of (a+b);
- and
- shaping the resultant mixture into a generally elongated______*.
A method for forming a solid fuel composition for destroying creosote within a chimney flue of a solid fuel burning appliance, comprising the steps of:
- admixing a solid particulate combustible cellulosic material (a) and a creosote-destroying chemical agent (b);
- combining said cellulosic material (a) and chemical agent (b) to form a substantially homogeneous aggregate;
- forming said aggregate to render it into a solid elongated form.
A process for destroying creosote within a chimney flue of a solid fuel burning appliance, said flue having an undesirable accumulation of creosote deposits therein, comprising the steps of:
- inserting a creosote-destroying processed solid fuel composition into an existing fire within said appliance, said processed solid fuel composition comprised of:
- a. a solid particulate combustible cellulosic material;
- and
- b. a chemical agent that disaggregates creosote;
- providing ignition and combustion of said fire log within said appliance;
- releasing said chemical agent in a gaseous form within said flu;
- providing a substantially constant temperature, whereby effectiveness of said chemical agent is optimized thereby disaggregating and destroying the creosote deposits.
