NOVELTY - A fuel product is produced by pulverizing straws, drying pulverized materials, subjecting dried materials to thermal cracking, transporting to a cyclone dust collector, and separating gas from solid; condensing the obtained solid biological charcoal, rectifying and washing the gas obtained by the separation of the cyclone dust collector, and condensing the gaseous biological oil obtained by rectifying and washing; and mixing and mulling the collected biological charcoal, heavy biological oil and solid biological charcoal, heavy biological oil, condensed water, and surface active agent.    USE - Method of producing a fuel product (claimed) for use in thermal power plant or district-heating plant.    ADVANTAGE - The method is low production cost; has higher output capacity and better control of fast thermal cracking condition; and produces fuel product having high heat value and low sulfur content thus not agglomerating in the pipeline and combustion nozzle, having stable performance, and that is convenient to transport and store.    DETAILED DESCRIPTION - A fuel product is produced by:    (A) pulverizing straws, drying pulverized materials, subjecting dried materials to thermal cracking, transporting to a cyclone dust collector, and separating gas from solid;    (B) condensing the obtained solid biological charcoal, rectifying and washing the gas obtained by the separation of the cyclone dust collector, and condensing the gaseous biological oil obtained by rectifying and washing;    (C) collecting obtained low boiling pint biological oil obtained by rectifying and washing, condensing the gaseous biological oil, and collecting the biological oil at low boiling point;    (D) mixing and mulling the collected biological charcoal, heavy biological oil and solid biological charcoal, heavy biological oil, condensed water, and surface active agent; and    (E) compressing and pressurizing the condensed gas, and subjecting to thermal cracking.    An INDEPENDENT CLAIM is included for a fuel product comprising (wt.%) biological charcoal (30-60) having a particle size of not greater than 10 mu m, biological oil (2-15), surface active agent (0.2-1), and water (balance).    DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method of producing a fuel product. Drawing includes non-English language text.
