USE - The method is useful for preparing fuel gas using large rolled crushed straw and coal particles replaced block coal and coke and device (claimed).    ADVANTAGE - The method solves oil shale refining and development and utilization problems (claimed); and improves extruding hole increasing discharge area, and the particle discharging output efficiency by 10 times using six groups of rolling wheel in granulating machine.    DETAILED DESCRIPTION - Preparing fuel gas using large rolled crushed straw and coal particles replaced block coal and coke and device, comprises (i) using the extrusion hole with depth or length length less than 5 times the diameter to improve the particle material extruding rate more than ten times, (ii) rolling, and kneading, where the extruding hole plate (8) roller optimum number is: roller (4) with inner diameter of phi 800 mm are arranged in four groups; roller with inner diameter of phi 1200 mm are arranged in six groups; roller with inner diameter of phi 1600 mm are arranged in 1-12 groups, preferably roller with inner diameter of phi 1200 mm are arranged in 6 groups, the production capacity can reach 15 tons/hour, power is 600-1000 KW, (iii) setting the device, taking straw, plant stem, branch with water content of 15-30%, and coal, crushing using mesh of phi 20-30 mm, which is good for high yield, and fast molding, (iv) increasing rolling and kneading many times, and smashing into slurry, extruding residual water content, where the output is high, but also can reach molding density of 200-1000 kg/m3, and (v) using gasification in order to increase the particle density, and using as solid fuel and storing according to the requirements, transferring basic shaped particles into a set of a granulating machine or rolling and kneading to improve particle intensity, where the density is 300-1200 kg/m3. An INDEPENDENT CLAIM is also included for processing particle with lignite, oil shale, coal, and crushed straw, comprising (i) rolling lignite with moisture content of 15-30% by two to three times, kneading into fine pulverized coal sludge, overflowing particles into extruding cylinder, drying the non-dehydrated lignite directly at 400-800 degrees C in high temperature fuel gas generator furnace easily with oxygen, and discharging steam gasification generated gas to push the gas engine to drive the generator, which improves one time than the direct burning coal power generation, at the same time, preferably fine pulverized coal in a gasification process has good tar release rate, the tar recovery is 8-12%, (ii) mixing with small amount of crushed oil shale or a coal containing water content of 15-30%, rolling and kneading into slurry, transferring into extruded column with temperature of 400-900 degrees C quickly reacting with oxygen to release the gas, using cooling system to congeal into shale oil, passing excess gas into the fuel gas turbine power generation, (iii) crushing pulverized coal with water content of 15-25%, rolling, kneading into thin pulverized coal particles, extruding out column particle, adding in 400-800 degrees C high temperature fuel gas generator with oxygen and steam or air and using efficient gasification to release the pulverized coal tar, where the generated gas pushes the gas engine, using gas engine tail gas waste heat and light for power generation, rolling and kneading each kilogram of pulverized coal and extruding into granules, where the generated electric energy efficiency reaches 3.4-4.8 KWh, at the same time, recovering coke oil of 90-120 g, replacing pulverized coal particles used in the cylinder gas furnace with lump coal and coke as a raw material, where the recycled tar is used as oil energy supplement, and (iv) rolling 15-35% aqueous pulverized coal containing straw by 3-4 times, kneading into slurry, overflowing extruded excess water into the cylinder, feeding directly into 400-800 degrees C high temperature fuel gas generator furnace and reacting easily with oxygen, discharging high calorific value fuel gas mixed gas via steam gasification to push gas engine to generate electricity, where the direct incineration of straw to improve power generation is increased from 1 kwh to 1.96-2.3 kwh, doubling performance, and 6-10% recycling tar.
