Benefits of technology

The invention is a method and process for taking unwanted forest fuel loads in woodland, forested, and wild-land / urban interface areas, and converting them into densified firelogs for sale. This method reduces the need for harmful and polluting controlled bums, and can be used in areas where thinning and fuel reduction operations were previously not economically feasible. The method also provides a higher margin for the sale of the firelogs and reduces transport costs. The process improves air quality by burning the firelogs cleaner than alternatives. The method involves gathering secondary forest growth, grinding it, and drying it to create a firelog that can be sold and used to fund thinning and fuel reduction operations.

Problems solved by technology

The competition in the marketplace for power plant fuel, because of very low cost fossil fuels, drives down the value of the wood material for this purpose.

Embodiment Construction

[0023] The methods and apparatus of the present invention will now be described with simultaneous reference to FIGS. 1 and 2. Mechanical thinning of woodland, forest, or world-land / urban interface is performed by means well known to practitioners of such operations. In this operation and by means of the system according to the present disclosure, it is not necessary to harvest or damage large trees not deemed to be part of the area fire fuel load. Material such as woody underbrush, manzanita, down, dead, and even rotting wood, is gathered in this step, leaving viable trees alone. Material infected with a fungal pathogen such as that causing Sudden Oak Death is equally desirable and suitable. The gathering of such “secondary forest products” is reflected by step 20 in FIG. 2.

[0024] The material as gathered is then processed by a suitably-sized wood reduction apparatus 22 such as a “hog grinder,” or “tub grinder,” which may be at a site immediately adjacent to a location at which the...

Abstract

A method of manufacturing firelogs from unwanted or diseased forest wood is disclosed. The method includes the steps of gathering such unwanted wood products from a forest and on-site grinding and drying those wood products into ground material prior to extruding same into a firelog. The sale of the firelog can then be used to pay for further gathering of the unwanted wood. Moreover, the machines used to grind and dry the material can be powered by burning the unwanted firewood as well.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. Provisional Ser. No. 60 / 571,108 filed on May 14, 2004.FIELD OF THE DISCLOSURE [0002] The present disclosure generally related to densified wood products, and more particularly relates to methods of manufacturing such wood products or firelogs. BACKGROUND OF THE DISCLOSURE [0003] The invention described in this filing pertains to the field of the manufacture of artificial firelogs, and a system for processing wood waste from forest, woodland, wildland, and urban-wildland interface regions, into densified wood firelogs, and a system whereby utilizing unwanted wood materials in forested and wooded areas as raw material in such firelogs enables otherwise cost-prohibitive, but important, thinning operations. Additionally, the invention enables the high-value utilization of diseased and fungus-infected wood needing to be cleared from these areas. [0004] It has become apparent and much discussed over the...
