Abstract
The invention discloses novel environment-friendly biomass pellet fuel. The pellet fuel is characterized by being prepared by a method comprising the following steps: 1) drying forestry wastes in the sun and powdering wood shavings; 2) drying straws in the sun after pretreating the straws and grinding the straws into powder, wherein the pretreatment method comprises the step of spraying a pretreatment solution on the straws uniformly; the spray amount is 500ml/kg; the pretreatment solution comprises 1-1.5% of oxalic acid, 0.05% of citric acid and the balance of water by mass; 3) fully mixing 50-65 parts of forestry waste powder, 20-28 parts of straw powder, 2 parts of wood shaving powder, 5-8 parts of sawdust and 1 part of plant ash by weight and extruding the mixture into columnar pellets. The prepared pellet fuel has calorific value of 7200-9100kcal/kg, has the advantages of low ash content, high gas outlet and low content of tar in fuel gas when being used in gasifiers and can be used in boilers instead of fuel coal, thus reducing emission of carbon dioxide and sulfur dioxide.
