Abstract
Biomass is prepared for use as a fuel or chemical feed stock either by processing biomass to provide particles or by utilizing such particles that have been independently produced, in either case at a location remote from consuming sites. At a thus situated location, particles are delivered to at least one gas producing section and to a drying section with hot producer gas utilized in the drying section in a manner to so reduce the moisture content of the particles as to render the particles a more efficient fuel or chemical feed stock. A minor portion of the producer gas is or may be used for various purposes such as fuel for a power plant to operate conveyors and particle forming apparatus, drying or heating of particles being delivered to the sections, or drying of particles subsequently to be consumed at the same or other particle producing site, in any case enabling biomass particles to be processed at sites remote from consuming sites with an economic advantage attained between the dried particles and undried particles.
