Baling & Roundwood Hauling for Fireline and WUI Fuels Reduction Woody Biomass: Alternative to on-site Chipping

Baling & Roundwood Hauling for Fireline and WUI Fuels Reduction Woody Biomass

Abstract  In this 17-slide Powerpoint presentation, Jim Dooley explores the challenges of on-site chipping of fireline debris and woody biomass and proposes Forest Concepts’ patent-protected baling technology as a solution.  The presentation covers potential benefits such as labor and cost reduction. In addition, depictions of applications at test sites are included. About the Publication  Dooley, …

Moisture Content of Baled Forest and Urban Woody Biomass During Long-Term Open Storage

Abstract This article describes how the moisture content of baled woody biomass varied during long-term open-air storage under conditions in the Pacific Northwest region of the United States. Large rectangular bales of forest and urban biomass were produced beginning in August 2015 and periodically until June 2016. Weights were measured approximately monthly until the entire …

Work Element Time Study of a Prototype for Baling Forest Residual Biomass into Large Rectangular Bales

Abstract  The productivity of forest biomass collection equipment is highly dependent on site conditions, spatial distribution of biomass, operator skill, and functional design of the equipment used. A prototype woody biomass baler was used to produce large rectangular bales of woody biomass. Rectangular bales enable high payloads during transport and efficient storage at centralized processing …

Baling Woody Residues

Conceptual Specification of Forest Utility Balers for Woody Biomass

Abstract  The forest utility modular woody biomass baler is designed to maximize recovery of forest residuals from small/remote/stranded landings, scattered roadside windrows and piles, thinnings from hand crews, and forest management prunings. The baler module is designed to be incorporated onto a wide range of undercarriages and prime movers. The baler module can be mounted …

Conceptual Specification of Large-Bale Forest Residuals Balers

Abstract The large-bale modular woody biomass baler is designed to maximize daily production while baling previously piled logging slash, forest residuals, thinnings from hand crews, and forest management prunings. The baler is intended to be supported by an excavator-type grapple loader to feed biomass into the baler and handle bales produced much like a grinder …

Conceptual Specification of Forest Residues Balers using the Appreciative Design Method

Abstract  Baling of fine forest residuals such as tops, branches, and thinnings is expected to reduce the cost of collection, transport, and processing. Baling may enable economical access to currently stranded biomass resources that are inaccessible to large in-woods grinders and specialized chip hauling vehicles. The technical feasibility of baling logging slash branches and tops …

Design of a Forest Residue Baler – Specification of Bale Dimensions

Abstract Specification of bale dimensions, configuration, and density are among the first decision decisions to be made for the design of a new class of forest biomass balers. The engineering team at Forest Concepts updated earlier work on baling of urban woody biomass to the context of forest residuals and the BRDI project. Revised functional …

Square Bales of Woody Biomass

Square Bales of Woody Biomass for Improved Logistics

Abstract  The majority of fuels reduction work is conducted by hand crews in the wild and urban interface and near in-forest recreation/administrative assets. Today, most of the biomass is either piled for burning at some future time or is dragged to the roadside for chipping. In many districts, disposal of chipped or whole brush is …

Collecting Woody Slash

Interfacing Forest Engineering with Bioenergy Production

Abstract  Woody biomass from forestland, urban greenbelts, and residential areas has the potential to provide more than 150 million tons per year of cellulosic feedstocks for biorefineries, pellet fuels, and fermentation. Production sites range from urban lots to large wildland forest tracts. Destinations range from small urban boutiques to large remote industrial complexes. The systems, …

Catastrophic failure from parallel to grain tension, not shear

Mode of Failure Model for Cutting Solid Section Biomass

Abstract Solid section biomass, such as wood and the node-zone of crop residues, has distinct modes of failure when loaded in cross grain shear. Shear bar design plays a part in determining what the failure mode will be at a given depth of penetration. Other factors include shear location relative to an unconstrained end and …
