Safety and energy-saving combustion furnace

Abstract

The invention discloses a safety and energy-saving combustion furnace. The safety and energy-saving combustion furnace comprises a furnace body and a furnace table arranged at the upper end of the furnace body. Landing legs are arranged at the bottom of the furnace body. A hearth barrel is arranged in a hollow cavity of the furnace body. A grate is arranged at the bottom of the hearth barrel. Vertical vertical-through air suction grooves are evenly formed in the inner wall of the hollow cavity of the furnace body. Exhaust holes are formed in the positions, located between every two adjacent air suction grooves, of the furnace body, exhaust hole outlets are formed in the oblique face of the furnace table, and exhaust hole inlets are formed in the outer wall of the furnace body. Guide vanes are arranged at the positions, located at the top ends in the air suction grooves, of the outer wall of the hearth barrel, and the lower end of the hearth barrel is connected to a bottom hearth base in a sleeved manner. A slag cavity is formed by the bottom hearth base and communicates with air inlet holes. By means of the safety and energy-saving combustion furnace, the combustion time of honeycomb briquette can be controlled, meanwhile, the generating amount of carbon monoxide is greatly reduced, and using is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of coal furnace equipment, in particular to a safe and energy-saving oven. Background technique [0002] Coal stove is a stove fueled by coal. Because of its long burning time and quick and convenient use, it is still widely used in rural China, mainly for heating in winter and cooking and boiling water. The structure of the existing domestic coal stove is generally as follows figure 1 As shown, the furnace body 1 is hollow to form a furnace 4, a furnace grate 2 is arranged in the furnace 4, honeycomb briquettes 3 are placed on the furnace grate 2 to burn, and a slag chamber 5 is arranged at the lower end of the furnace grate 2, and the slag chamber 5 is connected to the air inlet 6. There is one biggest disadvantage of this traditional coal stove. When the honeycomb coal is not fully burned, it will produce a large amount of carbon monoxide gas. Causes hypoxia in the body tissue, leading to suffocation an...

Problems solved by technology

The structure of the existing domestic coal stove is generally as follows figure 1 As shown, the furnace body 1 is hollow to form a furnace 4, a furnace grate 2 is arranged in the furnace 4, honeycomb briquettes 3 are placed on the furnace grate 2 to burn, and a slag chamber 5 is arranged at the lower end of the furnace grate 2, and the slag chamber 5 is connected to the air inlet 6. There is one biggest disadvantage of this traditional coal stove. When the honeycomb coal is not fully burned, it will produce a large amount of carbon monoxide gas. Causes hypoxia in the body tissue, leading to suffocation and death; from the beginning of liberation to the present, there are countless cases of carbon monoxide poisoning deaths caused by improper use of coal stoves in rural areas in China. In addition to requiring indoor ventilation when using coal stoves, So far, there is no good solution; but in order to save coal and prolong the burning time, when farmers do not need to cook or need heating, they will increase the burning duration and reduce the burning temperature by reducing the amount of air entering the honeycomb coal. , but doing so will further promote the production of carbon monoxide and increase the toxicity of carbon monoxide
