AI Technical Summary

Benefits of technology

The patent describes a new type of firelighter that uses starch instead of liquid hydrocarbon to reduce the negative impact on the environment and economy. The starch helps to prolong the burn time and increase the amount of heat transferred to the primary fuel being ignited. Additionally, the starch helps to slow down the combustion process, resulting in more efficient use of the firelighter. The firelighter is safe to use and does not have any safety concerns. The technical effect of this innovation is to provide a safer, cost-effective, and environmentally friendly firelighter that burns stable and efficiently.

Problems solved by technology

Heat is often released above the primary fuel bed, and hence wasted, with traditional firelighters, which do not contain starch.

examples

[0029]An embodiment of the invention will now be described by way of example.

[0030]69 parts by weight of a regular production firelighter emulsion was made. This comprised 80% kerosene and 20% by weight of aqueous urea formaldehyde resin, which itself is made up of 40% solids urea formaldehyde resin in water.

[0031]To this was added 30 parts by weight of wheat starch and the mixture was mixed until homogeneous. To this mix was added 1 part of 1 molar hydrochloric acid. The mix was mixed rapidly and within seconds poured into moulds to set. After setting, the moulded blocks produced were scored, sealed into polyester packs to prevent evaporative loss and allowed to equilibrate for 24 hours.

[0032]A duplicate control test was run alongside with no starch added. This contained 99 parts regular production firelighter emulsion made using 80% kerosene and 20% by weight of aqueous urea formaldehyde resin, which itself is made up of 40% solids urea formaldehyde resin in water. 1 part of 1 mol...

Abstract

A firelighter comprising a solidified emulsion of a liquid hydrocarbon encapsulated in polymerised aqueous resin, wherein the liquid hydrocarbon is present in an amount of 30 to 75% by weight of the firelighter, and wherein the firelighter also contains starch.

Description

FIELD OF THE INVENTION[0001]This invention relates to solid firelighters often generically known as “white firelighters” of the type which may be used to initiate combustion of the primary fuel in barbecues [BBQs] or domestic wood or coal fires. Firelighters can be used irrespective of whether the primary fuel is in the form of charcoal (lump wood or briquettes), natural wood as used in outdoor wood fires or coal as used in domestic indoor fires.BACKGROUND TO THE INVENTION[0002]So called ‘white’ firelighters are well known, having been available for decades, and are supplied in the form of a scored ‘board’ or as individual pre-formed units. Such firelighters comprise a solidified emulsion consisting of a closed cell matrix of a polymerised urea-formaldehyde [UF] resin containing a combustible material. The combustible material is generally a liquid hydrocarbon or similar, at levels of approximately 80% by weight of the total firelighter. The UF resin matrix is formed in-situ through...
