ARTIFICIAL FIRELOG USING NON PETROLEUM WAXES
USA Patent No. 8,007,550 issued August 30, 2011
European Patent No. 2104727 issued February 29, 2012
Canada Patent Pending
This patent addresses unique methods for formulating manufactured firelogs using specific blends of combustible non-petroleum waxes, based on the physical and chemical characteristics of the non-petroleum wax materials utilized. Fire logs made using the patented methodology have improved environmental sustainability and exhibit better burn performance than firelogs made from traditional methods.
ARTIFICIAL FIRELOG USING OIL AND/OR FAT RETAINING MATERIALS
USA Patent No. 8,123,824 issued February 12, 2012
European Patent No. 2108034 issued February 11, 2011
Canada Patent Pending
This patent addresses the use of unique blends of combustible non-absorbent materials, typically oil or fat retaining agricultural by-products, meal, grains or seeds in combination with combustible petroleum or non-petroleum waxes to manufacture better performing firelogs. Using these proprietary techniques firelogs can be made with lower added wax content and still maintain or exceed the performance characteristics of firelogs made from traditional methods.
CRACKLING FIRELOG PATENT
USA Patent No. 6,017,373 issued on January 25, 2000
Canada Patent No. 2,380,593 issued September 23, 2003
European Patent No. 1203064 issued December 17, 2003
The patent pertains to the use of coriander seeds in firelogs to create a crackling sound that mimics the sounds produced while burning wood logs. The random crackling sound continues for a similar duration as when burning wood logs and provides a similar amplitude and frequency of the crackling sound produced from burning wood logs.
ILLUMA AUTOMATIC FUELING OF LIQUID FUEL BURNERS PATENT
USA Patent No. 9,267,681 issued on February 23, 2016
The patent addresses the use of a unique method for fueling liquid burners in illuma® bio-ethanol fireplaces and fire pits. This method indicates when the fuel level is low, and allows for the safe addition of fuel to the appliance while the fire is burning. It eliminates the dangers associated with pouring the ethanol in the burner, avoiding spills and flashbacks.
