Abstract

An organically clean biomass fuel formed of mixture of a powder, which may be either dried, cellulosic product, wood charcoal powder, and/or a combination of the two, and a fluid, which may be vegetable oil, vegetable alcohol or a combination of the two. A centrifugal machine dries moist, cellulosic product and extracts black liquor. A grinder transforms the dried, cellulosic product into powder. Gum may be extracted from the vegetable oil or vegetable alcohol. A batch mixer or vibrating vessel mixes the powder and the fluid together; the fluid moisturizes the powder. Depending upon the relative amount of the fluid as compared to powder, the mixture will either be in a liquid cream state or a doughy state. If the latter, the mixture may be pressed into briquettes or ingots.
