Energy-saving and environment-friendly firewood burning furnace

Abstract

The invention discloses an energy-saving and environment-friendly firewood burning furnace. The energy-saving and environment-friendly firewood burning furnace comprises a furnace shell and a hearth, and is characterized in that the furnace shell is of a closed cylindrical structure arranged outside the hearth in a sleeving manner, the hearth comprises a burning barrel and an outer barrel arranged on the outer side of the burning barrel in a sleeving manner, a gap is formed between the outer wall of the burning barrel and the outer barrel to form an airflow cavity, an air supply assembly communicating with the airflow cavity is arranged at the bottom of the outer barrel, and the burning barrel and the outer barrel are of a conical structure with the small upper portion and the large lower portion. According to the energy-saving and environment-friendly firewood burning furnace, the whole hearth is set to be of the conical structure, the air supply efficiency is improved, higher airflow can be obtained through burning, the air and fuel gas mixing ratio needed for premixed burning is achieved, pyrolysis of combustible molecules and better gasification of carbon particles are achieved, combustibles are completely burned to obtain high-heat-value fuel gas, accordingly, the higher hearth temperature and the continuous and stable furnace opening high temperature are obtained, the burning furnace opening temperature is continuously stabilized to be above 1,050 DEG C, energy consumption is low, and output is high.

Description

technical field [0001] The invention relates to the technical field of combustion devices, in particular to an energy-saving and environment-friendly wood-burning stove. Background technique [0002] The emergence of new energy sources such as natural gas, coal, and electricity has changed human life in modern times, but at the same time it has also brought environmental pollution and damage to humans. The inexhaustible and inexhaustible use and combustion of biofuels has once again been valued by human beings; at the same time, since the 21st century, due to the widespread use of natural gas, liquefied gas, coal, electricity and other energy sources, the main The waste of fuel branches and straws has caused new problems for environmental protection, and domestic waste has endangered human living space and the environment to a greater extent. Therefore, the research and discussion on the use of biofuels in various countries in the world has entered a new stage. Europe and t...
