Method for preparing fuel from extruded and soft straws

The invention discloses a method for preparing a fuel from extruded and soft straws, and belongs to the field of processing of biomass fuels. The method comprises the following steps: ultrasonic immersion and hot rolling pretreatment, grinding pre-crushing, semi-anaerobic baking secondary treatment and ultrafine crushing of the extruded and soft straws; addition of illegal cooking oil, activated sludge and kelp slurry as an adhesive; high-speed of the adhesive and obtained crushed straw particles; and compression molding using gradual pressure increase cold compression. The prepare biomass fuel has the advantages of smooth surface, strong adhesion, improved combustion heat and improved combustion quality. 本发明公开了种膨软秸秆制备燃料的方法，属于生物质燃料的加工领域，该方法采用超声浸泡和热碾压预处理，研磨预粉碎，半无氧烘焙二次处理和超细再粉碎进行处理膨软秸秆，并添加有地沟油、活性污泥和海带浆作为黏合剂与粉碎后的秸秆颗粒进行高速共混，最后采用逐步升压的冷压缩进行压缩成型，制备出的生物质燃料具有表面光滑，粘结力强，且燃烧热和燃烧质量均有不同的提升。
