Biomass burning furnace and air intake method

Abstract

A biomass burning furnace which is clean, energy-saving and convenient to use comprises a casing, a combustion system and a lifter. The combustion system uses a multiple-layer air intake cover and is provided with a lower combustion barrel bottom air inlet, a lower combustion barrel upper edge air inlet and a multiple-layer air inlet. An upper combustion barrel is fixedly connected with a furnace base and an inner lateral wall of the casing, a lower combustion barrel is placed on a support of the lifter and can lift vertically, the lower combustion barrel and the multiple-layer air intake cover form a movable type embedded structure, and the lifter is of a door curtain structure, charging of the lower combustion barrel is performed through a switch of a door. The multiple-layer air intake cover has the effects of brightening fire, gathering energy and achieving pyrolysis combustion of tar and steam. The biomass burning furnace adopts direct-ignition combustion and natural air feeding, and is clean, hygienic, free of smoke in ignition and quick in fire exchange. Biomass sources required by the biomass burning furnace are wide and include core woods and various by-products of agriculture and forestry, processed biological rids can serve as fuel, and the biomass burning furnace is suitable for agricultural production and rural families.

Description

technical field [0001] The invention relates to a biomass burning device, in particular to a biomass burning furnace which is not only clean and energy-saving, but also convenient and practical. Background technique [0002] The utilization of biomass energy is a problem that the world has focused on, and the utilization rate of the simple and primitive combustion method is extremely low. Over the years, our country has invested a lot of money in promoting various firewood-saving stoves, and the combustion technology has made great progress, but it has not satisfied the farmers' friends, so the popularization rate is not high. The reason is that there is no multi-layer air intake device, incomplete combustion, too much smoke, no energy gathering, and the chimney hole is too large, not only carbon monoxide and tar take away energy, but also a considerable amount of heat energy escapes from the chimney hole, resulting in a large energy loss , and the operation is not very con...

AI Technical Summary

Problems solved by technology

In order to overcome the disadvantages of many operating steps and inconvenient use of the existing biomass stoves, the invention adopts a lifter installed on the door, so that the lower combustion cylinder can move with the lifter, and can also go in and out with the door
