Abstract

The utility model relates to a domestic multi-use furnace with secondary air combustion which is high efficient and energy-saving. The domestic multi-use furnace comprises a furnace body, an internal furnace, and a furnace bar; wherein, a fuel feeding port is arranged on the furnace; and the bottom of the furnace is an inlet chamber. The utility model is characterized in that an inlet channel is arranged between an outer wall of the furnace body and the internal furnace; suction ports are evenly distributed on a cylinder wall at the top of the internal furnace; the inlet chamber is communicated with a hearth through the inlet channel and the suction ports on the cylinder wall at the top of the internal furnace, thus a hearth secondary air structure is formed; a hot water tank for the recovery of waste heat is arranged on a fire hole. When fuel burns in the hearth and enters into an anoxycausis state, part of the burning forms flame at the same time, and part of the burning forms combustible gas which comes to the fire hole; the combustible gas which comes to the fire hole is fully burnt again at the fire hole under the oxygen supply through secondary air, so as to rapidly promote the firepower at the fire hole, thus a high temperature heat source which is more higher than a traditional stove is formed at the fire hole; therefore, the heat energy generated by the burning can be fully utilized; compared with the traditional stove, the maximum energy conservation can reach 70 percent.

Description

High-efficiency multi-purpose energy-saving furnace

technical field

The utility model relates to a living stove, in particular to a high-efficiency multi-purpose energy-saving stove for secondary air-intake combustion used in households.

Background technique

Known family use stoves are made of a body of heater, a furnace and a furnace bar. The body of heater is provided with a fuel inlet, and the bottom of the body of heater is an air inlet chamber. This kind of traditional stove has the following disadvantages when used: one is that due to insufficient oxygen supply during combustion, the fuel is not fully burned, which will cause a lot of waste of fuel; environment, and also poses great harm to the human body; third, there is no waste heat recovery device, and the thermal efficiency is very low. In order to solve the above-mentioned deficiencies, many inventors have designed various energy-saving furnaces, but due to technical reasons, most of them do not solve the above-mentioned problems well, so they are not adopted by users in the market.

Contents of the invention

The technical problem to be solved by the utility model is to provide an improved high-efficiency multi-purpose energy-saving furnace. The energy-saving furnace not only has a simple structure, but also has sufficient combustion, high thermal efficiency and low pollution.

The technical scheme adopted by the utility model to solve the technical problem is: this high-efficiency multi-purpose energy-saving furnace includes a furnace body, a furnace furnace and a furnace bar. The furnace body is provided with a fuel adding port that can be closed, and the bottom of the furnace body is an air inlet chamber. , there is an air inlet between the outer wall of the furnace and the furnace, and the top wall of the furnace is evenly distributed with air inlets, and the air inlet chamber communicates with the furnace through the air inlet and the air inlet on the top wall of the furnace. The secondary air intake structure of the furnace is formed, and a hot water tank for waste heat recovery is installed at the furnace mouth. . When the fuel is sent into the furnace from the fuel adding port and burns for a period of time, the temperature in the furnace rises rapidly (about 500°C) due to the asbestos insulation structure around the furnace, and the furnace enters an oxygen-deficient combustion state. At the same time, the burning part forms a flame, and the part forms a combustible gas rushing to the furnace mouth. Since the furnace mouth has the function of secondary air intake, the combustible gas rushing to the furnace mouth under the secondary air intake and supplementary oxygen will be fully burned again at the furnace mouth, so that the firepower at the furnace mouth will be rapidly increased, and the role of the asbestos insulation layer The heat energy generated during combustion in the lower furnace is basically sent to the furnace mouth, which greatly increases the temperature at the furnace mouth, and at the same time forms a high-temperature heat source at the furnace mouth that is much higher than the traditional stove, so the combustion The heat energy generated is fully utilized, thereby achieving a substantial energy saving effect.

As an improvement of the utility model, the hot water tank has a split structure, which is sleeved on the upper part of the furnace, and a smoke exhaust chamber is provided on the top. Use the high-temperature heat radiation from the furnace mouth to heat the cold water in the water tank, further improving the utilization rate of heat energy and achieving the multi-purpose effect of one furnace; and setting a smoke exhaust chamber on the upper part of the hot water tank can fully increase the burning time of smoke in the furnace , so that the soot burns more fully.

As another improvement of the utility model, the furnace gall is cast iron, and the furnace gall is wrapped with an insulating layer on the lower outer wall of the hot water tank. The furnace made of cast iron can increase the service life of the furnace. Because of its good heat preservation effect, it not only increases the temperature in the furnace, but also reduces heat loss.

The beneficial effects of the utility model are:

1. The structure is simple, easy to use and maintain, and safe and reliable.

2. The fuel is fully burned, and the energy saving effect is obvious. Due to the use of the secondary air inlet materialized combustion structure, the fuel is fully burned in the furnace, the temperature of the furnace mouth is greatly improved compared with traditional similar products, and the firepower stronger than the traditional stove can be obtained with less fuel; And compared with traditional stoves, the energy saving can reach up to about 70%.

3. Low pollution. Since the fuel is fully burned in the furnace, very little smoke is produced.

4. Multi-purpose. There is a waste heat recovery water tank at the furnace mouth, which can use its thermal radiation efficiency to obtain hot water, and one furnace can be used for multiple purposes.

5. A wide range of fuels are available. It can be firewood, coal, or combustibles such as plant stems, which are very easy to obtain.
