Description

Energy-saving hot air coal-fired furnace

technical field

The utility model relates to a coal-fired furnace, in particular to an energy-saving hot air coal-fired furnace.

Background technique

Coal-fired stoves are stoves that use coal as fuel, and are used for heating and cooking in winter in the north. The common structure of ordinary domestic coal-fired furnace is to set a furnace inside the furnace body, to set a furnace bridge at the bottom of the furnace, and to set a slag outlet below the furnace bridge. After the fuel is added from the top of the furnace body, the air required for fuel combustion enters from the bottom of the furnace bridge, and the air that enters is cold air, which is not conducive to the utilization of coal-fired heat energy and cannot achieve the effect of energy saving. Secondly, in the process of coal combustion, incompletely burned coal dust exists in the combustion exhaust gas, and the existing coal-fired furnace does not have the function that is conducive to the full combustion of coal dust. At last the existing coal-fired stove adds coal from the top of the body of heater. When a kettle or cooker is placed above the body of heater, it is extremely inconvenient to feed.

Utility model content

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide an energy-saving hot-air coal-fired furnace, which preheats the incoming air, improves the utilization rate of heat energy, and is conducive to the full combustion of coal-fired, so as to The purpose of saving energy and reducing consumption.

In order to solve the above technical problems, the utility model adopts the following technical solution: an energy-saving hot air coal-fired furnace, including a cylindrical furnace body and a furnace core, characterized in that: a transverse partition is arranged on the upper part of the furnace body , the center of the transverse partition is provided with a furnace core installation hole; the furnace core is a cylindrical structure with two ends open, and the upper port is provided with an outer flange, and the furnace core is hoisted on the furnace core through the outer flange. In the hole, there is a distance between the lower end of the furnace core and the bottom surface of the furnace body, the lower port of the furnace core is provided with a furnace bridge, and the upper end of the side wall of the furnace core is circumferentially distributed with furnace The secondary combustion air-gathering holes communicated with each other, the furnace body is provided with an air inlet close to the lower surface of the transverse partition, and the upper part of the side wall of the furnace body is provided with an exhaust port connected with the exhaust pipe. The exhaust vents are located above the transverse partitions.

Using the above scheme, coal is added to the furnace core, the air inlet is connected with the blower, and air is blown into the furnace body. The air entering the furnace body rotates along the outer wall of the furnace core and descends to the lower end of the furnace core. Preheated by the heat generated by coal combustion in the furnace core, most of the preheated air enters the furnace core from the lower end of the furnace core to provide sufficient oxygen for coal combustion. A small part enters the upper part of the furnace core through the secondary combustion air-gathering hole to provide oxygen for the secondary combustion of coal dust, which is conducive to the full combustion of coal and has the effect of energy saving and emission reduction.

In the above solution: the upper part of the side wall of the furnace body is also provided with a coal charging port, the coal charging port is also located above the transverse partition, and the coal charging port is provided with a small coal charging door. The coal is added from the coal inlet, and there is no need to remove the pot on the furnace body every time the coal is added, which is more convenient to add coal.

In the above solution: the lower part of the furnace body is also provided with a slag removal port, and a slag discharge door is provided on the slag removal port. Easy to remove slag.

In the above solution: the furnace wall of the furnace body is provided with an insulating layer. Avoid heat dissipation loss and improve heat utilization.

Beneficial effects, the utility model improves the structure of the coal-fired furnace, enters the air from the upper part of the furnace core, and the intake air is fully preheated in the furnace body before being used for coal-fired combustion, so as to achieve the purpose of saving energy and reducing consumption. The new type can also achieve full secondary combustion of fuel, achieving the effect of energy saving and emission reduction.
