Abstract

The utility model discloses an energy-saving firewood/coal furnace which belongs to household furnaces, particularly a furnace using firewoods and coals as fuel. The energy-saving firewood/coal furnace comprises a combustion chamber, a furnace mouth and a chimney, and is characterized in that one end of the horizontal type combustion chamber is connected to a pre-combustion chamber; the chimney is mounted at the other end of the horizontal type combustion chamber; secondary air inlets are formed on the two side walls close to one end of the pre-combustion chamber; the furnace mouth is positioned at the top of the combustion chamber; a furnace cover capable of being opened and closed is mounted at the top of the pre-combustion chamber; an air inlet is formed in the middle of the side surface of the pre-combustion chamber; a furnace grate capable of being pushed and pulled is mounted at the bottom of the pre-combustion chamber; and an ash removing door is arranged below the furnace grate. Since the pre-combustion chamber is arranged, firewoods or coals can be stored and pre-combusted in the pre-combustion chamber, and pre-combusted mixing gas enters the combustion chamber; and since the secondary air inlet is formed on the side wall of the combustion chamber, the mixing gas can obtain sufficient oxygen from secondary air and be fully combusted. The furnace grate capable of being pushed and pulled can adjust the size of the degree of fire, and a cylindrical water heater wound around the chimney can make full use of residual heat. Therefore, the energy-saving firewood/coal furnace has the advantages of wide application range of fuel, high thermal efficiency and the like.

Description

Energy-conservation firewood and coal stove
Technical field
The utility model belongs to Domestic stove, particularly uses faggot and the coal stove and accessory as fuel.
Background technology
Usually use the stove and accessory of stalk as fuel, be not suitable for burning coal, the energy-saving stove that be fit to burn coal is not suitable for burning stalk and faggot because combustion chamber volume is less.
The utility model content
In order to overcome the deficiency that existing faggot stove and coal furnace can not be general, the purpose of this utility model provides a kind of energy-conservation firewood and coal stove, and this energy-conservation firewood and coal stove not only is fit to use faggot to be fuel, and can be fuel with the coal.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of energy-conservation firewood and coal stove, comprise combustion chamber, fire door, chimney, it is characterized in that: horizontal combustion chamber one end connects precombustion chamber, the other end is equipped with chimney, and there is the secondary air mouth two side of close precombustion chamber one end, and fire door is positioned at top of combustion chamber, but the folding bell is equipped with at described precombustion chamber top, there is air inlet at the middle part, side, but the fire grate of push-and-pull is equipped with in the bottom, under the fire grate shoot door is arranged.
Described fire door is 1-3.
On the described chimney around the cylindrical shape water heater.
The beneficial effects of the utility model are owing to be provided with precombustion chamber, faggot or coal can here store and pre-burning, gaseous mixture after the pre-burning enters the combustion chamber, because the secondary air mouth is arranged on side wall of combustion chamber, gaseous mixture obtains sufficient oxygen from secondary wind, completing combustion, and the push-and-pull fire grate can be regulated the big or small and strong and weak of the intensity of a fire, the cylindrical shape water heater that is looped around on the chimney more can make full use of waste heat, therefore the utlity model has wide, the thermal efficiency advantages of higher of use fuel range.
