A biomass fuel stove

Abstract

A biomass fuel furnace relates to combustion equipment and comprises a furnace body, a furnace pipe and a furnace table, wherein the side wall of the furnace pipe comprises an inner layer and an outer layer, plural air exhaust holes are disposed in the outer layer, plural air ducts extended and disposed from bottom to top are disposed between the inner layer and the outer layer, and the air exhaust holes are upper ports of the air ducts; and the outer surface of the outer layer is winded by a heating pipe. The biomass fuel furnace provided by the invention has the beneficial effect that when wind enters the furnace body, one part of the wind directly enters the furnace pipe to realize sustained combustion of fuels; and the other part of wind enters the air ducts and then flees from the air exhaust holes into the middle upper part of the furnace pipe. When the wind in the air ducts flees into the furnace pipe, flame gets close to the center shaft of the furnace pipe and is avoided from running around. After multiple air flows gather inside the furnace pipe, wind speed above the furnace pipe increases, air mobility in the fuel furnace is ensured, and the fuels can be completely burnt; and heat of the side wall of the furnace pipe is used to heat a water flow in the heating pipe so as to add functions of the fuel furnace and increase utilization rate of the heat.

Description

technical field [0001] The invention relates to combustion equipment, in particular to a biomass fuel furnace. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.). With the development of the market economy, under the call and request of international and domestic environmental protection departments, people pay more and more attention to resource reuse. Among them, biomass fuel, as a renewable energy source, is widely used due to its advantages of high combustion heat, easy storage, easy transportation, and no pollution. However, common biomass fuel stoves have the following problems: 1. The wind in the furnace body is unstable, causing the flame to fluctuate from time to time, which can easily ignite surrounding objects and even cause fires. 2. Poor ventilation, resulting in difficulty in starting a fire, insufficient fuel combu...
