Benefits of technology

[0007] The present invention is directed, according to one embodiment, to compositions comprising a combustible material or combustible materials and a blend, preferably a high melt point blend, comprising a modified renewable oil, preferably a plant oil, and a wax-based material(s) or a polymer(s). The preferred compositions of the present invention comprise about 50% combustible material(s) by weight of the total composition. The combustible material(s), according to one embodiment of the present invention, comprises a wood-based material, preferably comprising sawdust and/or wood flour. The blend, according to one embodiment, preferably comprises a renewable plant oil and preferably, substantially comprises a modified tall oil component. The modified tall oil is, according to an embodiment, comprised substantially of modified tall oil pitch, e.g., but not limited to tall oil pitch residue that has been saponified, neutralized, distilled, and acidulated. Not...

Problems solved by technology

A log manufactured from a tall oil component consisting substantially of an oxidized tall oil component has been found to quite often drip during burning indicating undesired free oxidized tall oil / wax blend on the surface of the fibers making it unsatisfactory for consumer use.

examples

[0052] Both laboratory and commercial scale tests were performed to evaluate the burn characteristics of the logs. A description of the laboratory scale test stand follows: after a particular log recipe was mixed and a log was extruded according to the processes described herein, the log was subjected to a burn test. The log was lit on both bottom ends of the log. Burn characteristics were observed and noted as they occurred. Noted burn characteristics may include the ease of ignition, the flame (size and movement), heat generation, log integrity (drip or breakage), level of smoke generation, ash produced, and flame propagation. Total burn time was noted. The logs were also measured or observed in relation to total weight, log density, log durability upon handling, hardness, heat exposure, and general appearance (presence of cracks, swelling and the like).

exemplary example i

[0055] A 5 pound fire log wax made of about 48% wood flour and about 52% molten liquid blend. The liquid blend was composed of about 80% modified (saponified, neutralized, distilled, and acidulated) tall oil pitch residue and about 20% polyethylene wax and had a viscosity of approximately 29 centipoise at 300 degrees Fahrenheit and a drop melt point of about 223 degrees Fahrenheit. The log was wrapped in a paper wrapper. The wrapper was lit in order to ignite the log at 6:45 a.m. The log became totally engulfed in flames at 6:50 a.m. and the log burned until 10:15 a.m.

exemplary example ii

[0056] A 6 pound fire log was produced by extrusion and was composed of about 44% wood flour and about 56% molten liquid blend. The liquid blend was composed of about 75% modified (saponified, neutralized, distilled, and acidulated) tall oil pitch residue and about 25% polyethylene wax. The liquid blend had a viscosity of approximately 23 centipoise at 300 degrees Fahrenheit and a drop melt point of about 228 degrees Fahrenheit. The log was wrapped in a paper wrapper and at 8:30 a.m. lit by lighting the paper wrapper. The log became totally engulfed in flames by 8:37 a.m. and burned until 12:25 p.m. Flame height was very good during about 95% of the burn time.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates generally to novel manufactured fire log technology. More particularly, the present invention relates to novel manufactured fire log compositions comprising renewable materials, and novel continuous processes for manufacturing the same. BACKGROUND OF THE INVENTION [0002] Fire logs have been used for many years as a source of heat in homes, etc. Fire logs are not only desired for the warmth they provide, but they also create a desirable cozy atmosphere. A traditional fire wood log consists of a section cut from a tree. Traditional wood logs have numerous disadvantages including but not limited to problems in relation to storage, use, emissions and disposal. For example, traditional wood logs typically are messy. The logs often leave chips of wood and bark behind. Because the logs are untidy, the logs are usually stored outside the home. Storing logs outside the home creates another disadvantage to the user, namely,...
