A biomass solid fuel which, when exposed to rain water, has a reduced COD in discharged water and has low disintegration-property, while suppressing an increase in cost. The biomass solid fuel obtained by molding pulverized biomass particles, such that mutual bonding or adhesion between pulverized biomass particles is maintained after immersion in water.

A method for fabricating a coconut shell heat producing device. Heat is applied to coconut shells to form carbonized coconut charcoal pieces. The charcoal pieces are ground to form coconut charcoal powder. A moistened blend is created that includes the coconut charcoal powder, a binder and water. The moistened blend is placed into a press. Pressure is applied in the press to form the moistened blend into the heat providing device. The heat providing device includes at least one hole extending through the device. In a preferred embodiment the heat producing device is a coconut shell charcoal log.

A method is provided for producing a solid fuel to be used as fuel for a pulverized coal boiler from wood biomass as a source material at a high mass yield and calorie yield by performing a grinding treatment in a mixture with coal. A solid fuel is produced by adjusting the moisture of a ground powder of wood biomass to between 8 and 50%; densifying the ground powder of wood biomass to a bulk density of 0.55 g/cm.sup.3 or higher (measured according to JIS K 2151-6 Bulk density test method); and then subjecting the ground powder of wood biomass to torrefaction under conditions of an oxygen concentration of 10% or less and a temperature between 170 and 350 C. Since the bulk density of a source material is high, a trouble in conveyance such as clogging of a rotary valve at an inlet of a carbonization furnace, or clogging of a cyclone after a drier due to excessive reject can be prevented.

Described herein is a method for isolating high carbon chipped wood charcoal fuel suitable for grilling food. According to one aspect, the method involves removing pyrolyzed wood charcoal from a kiln wherein the pyrolyzed wood charcoal comprises lumps, chips, smaller pieces, and dust particles. The pyrolyzed wood charcoal is passed over a first sieve that is configured to separate the lumps from the chips, smaller pieces and dust particles. The chips, smaller pieces and dust particles are then passed over a second sieve that is configured to separate the chips from the smaller pieces and dust particles. The resulting chipped wood charcoal is consistently sized to be small enough to pass through a food supporting grill grate and supportable by an underlying grid support, thereby allowing refueling while grilling without interruption.
