Wood stove capable of burning biomass pellet fuel

Abstract

The invention discloses a wood stove capable of burning biomass pellet fuel and belongs to the technical field of biomass pellet fuel equipment. The wood stove capable of burning the biomass pellet fuel mainly comprises cookware and a stove chamber, wherein a plurality of fins are distributed on the lower bottom surface of the cookware, a biomass pellet burner is arranged inside a stove wall so as to replace an original grate, a metal reflective surface which is smooth on the surface is installed on the periphery of the top of the biomass pellet burner, the reflective surface is arc-shaped and parallel to the lower bottom surface of the cookware, and the fins arranged at the bottom of the cookware are arranged in a radial mode. The wood stove capable of burning the biomass pellet fuel has the advantages of being simple in structure, easy to construct, convenient to use, and capable of achieving efficient cleaning burning of the biomass fuel, reducing pollution emission, effectively avoiding heat radiation of flames on the stove wall and the ground, improving the utilization rate of flame radiant heat, increasing the heat-absorption surface area of the cookware, improving the rate of utilization of smoke flow heat by the flames and finally enabling heat efficiency of a normal wood stove to reach over 40%.

Description

technical field [0001] The invention relates to a wood stove for burning biomass particle fuel, which belongs to the technical field of biomass burning equipment. Background technique [0002] China is a large agricultural country and one of the countries with the most abundant straw resources. According to relevant statistical results (Han Lujia, Yan Qiaojuan, Liu Xiangyang, Hu Jinyou. China's crop straw resources and their utilization status, Journal of Agricultural Engineering, 2002 (5): 87 ~91), my country produced about 640 million tons of straw in 1999, equivalent to about 320 million tons of standard coal in terms of calorific value, equivalent to 10% of the country's total energy consumption in 2009. For a long time, ordinary firewood stoves that directly burn firewood and straw have been widely distributed in rural areas of our country. However, the current main utilization method is mainly based on extensive combustion, which has a series of problems such as low eff...
