GB2395956A - Recycled particular/granular firelighter - Google Patents

Abstract

A fire lighter is formed from recycled granular/particulate material such as sawdust, wood shavings and wood flakes. Hydrocarbon fuel such as paraffin or kerosene is added to the particulate material. The majority of the particles have a particle size of less than 12 mm, or preferably less than 5 mm. The composition may comprise charcoal flakes, coal particles, aromatic wood flakes, aromatic essences, food essences or flavourings or a kerosene deodoriser. The composition may be used to light a stove, fire or barbeque.

Description

Description.

Fire igniters The invention relates to combustible compositions and includes compositions in which recycled materials are utilised.

Many known combustible compositions include those that are used as firflighters and charcoal igniters. Some of these compositions utilise fuel in the form of gel, wax or paste mixed with organic matter. These are commonly known as 'Brown' firflighters.

The most common of these compositions is the type known as the 'white' firflighter. Generally composed of a resin block in which is dispersed a large quantity of hydrocarbon fuel (urea-formaldehyde resin / kerosene).

Whilst being generally accepted as superior in performance to the 'Brown' firflighter in terms of burn time/fuel ratio its performance depends on the emulsification of kerosene into the resin base and subsequent hardening.

Poor emulsification and /or hardening can lead to difficulty in ignition, poor flames and general quality problems. Also associated with these firflighters is the high odour content and reduced performance once the protective packaging has been opened.

The manufacturing process of this firflighter utilises the use of formaldehyde, which is a known irritant and also high volumes of Kerosene.

We have now found that Open Fires, Wood burning Stoves and Barbeques can be ignited very satisfactorily using a recycled granular composition that does not utilise formaldehyde and has a relatively low hydrocarbon fuel content. The composition due to its granular nature with a range of differing particle sizes up to 1 2mm can be easily spread over the base of the required ignition area. As a result we have obtained ease of ignition, an efficient rate of combustion with a range of ignition points giving low heat loss.

The granular composition may be made by introducing selected recycled materials into a crusher and passing on through a grader to give a particle size of up to 5mm.

The graded materials are brought together in a mixing vessel to which the hydrocarbon fuel is added.

At this stage other materials such as odorants or aromatics may be added.

The preferred particulate compositions of the invention contain at least 75% by weight recycled materials and no less than 10% liquid hydrocarbon fuel.

The preferred hydrocarbon fuel being paraffin also known as kerosene.

l Whilst the bulk of the particle compositions should fall in the range of up to 5mm, it may also be advantageous to introduce a small percentage of Charcoal flakes or similar particles that are up to 12mm.

The following are examples of the invention.

For the purpose of definition recycled ash is wood stove/ firegrate ash and or boiler ash.

Example 1.

Crush and grade recycled materials to give particle dimensions of up to 5mm.

Ingredient weight 200gm recycled sawdusV wood shavings 275gm recycled ash.

Disperse mixture into mixing vessel and agitate.

Introduce over a period of time.25 parts by weight commercial paraffin.

The resultant granular mixture (mash) was a highly effective igniter for wood bumers, open fires & BBQ's.

Example 2.

The process of example 1 was repeated except that the recycled ash was reduced to 1.75 part by weight and Charcoal flakes were introduced.

Example 3.

The process of examples 1&2 was repeated except that the charcoal flakes were reduced to.50 parts by weight with coal dust at.50 part by weight introduced. Example 4.

As in all preceding examples except that aromatic wood flakes are added.

Example 5.

As in all preceding examples except that essential aromatic essences are added. e.g.; pine/citrus oils.

Example 6.

As in all preceding examples except that food flavourings or essences are added. Example 7.

As in all preceding examples except that a kerosene deodoriser is added are added.
