Description

Technical Field

[0001] This utility model belongs to the field of reverberatory furnace technology and relates to a nickel reverberatory furnace combustion device. Background Technology

[0002] Reverberatory furnaces are widely used in industrial production. They are one of the main equipment contributing to energy consumption, carbon emissions, and environmental pollution. Their efficiency directly affects the effectiveness of energy utilization and environmental protection. Existing utility model patent CN204301071U discloses a multi-oxygen combustion device. By designing the injection angle of the gas and oxygen, after the gas enters the furnace, it first comes into contact with and mixes with the root of the primary oxygen, causing some of the gas to form a flame at the root. The remaining gas is distributed to the kiln or combustion chamber, where it reacts violently with the secondary primary oxygen diffused in the furnace and is completely burned, thereby improving combustion efficiency. However, its primary oxygen and secondary primary oxygen setting structure is relatively complex, and the combustion efficiency is generally low. Utility Model Content

[0015] The present invention will now be described in detail with reference to the accompanying drawings:

[0016] As shown in Figure 1, a nickel reverberatory furnace combustion device includes a burner brick 1, which is a conventional burner brick used in nickel reverberatory furnaces. A first oxygen delivery pipe 2 penetrates the burner brick 1, with one end forming an oxygen outlet 3 through which oxygen can be delivered into the nickel reverberatory furnace. A sealing baffle 4 is provided at the other end of the first oxygen delivery pipe 2. A gas pipe 5, coaxially arranged with the first oxygen delivery pipe 2, passes through the sealing baffle 4 and delivers gas into the nickel reverberatory furnace. The delivered gas immediately and thoroughly mixes with oxygen at the oxygen outlet 3, thereby improving the combustion effect and oxygen utilization rate. The first oxygen delivery pipe 2 is inclined downwards and forms an angle of 3-10 degrees with the horizontal plane. A gas delivery pipe 6 is connected to the side wall of the first oxygen delivery pipe for delivering oxygen into the first oxygen delivery pipe 2. A first flame detector 7, horizontally arranged and penetrating the burner brick 1, is located within the burner brick. The lower part is horizontally arranged. An electronic igniter 8 is installed on the first flame detector 7. The electronic igniter 8 is installed on the first flame detector 7 in a conventional manner. The flame in the nickel reverberatory furnace can be detected and ignited through the first flame detector 7 and the electronic igniter 8. A second oxygen supply pipe 9 is provided inside the burner brick 1, which is located at the upper part of the burner brick 1. The second oxygen supply pipe 9 is arranged parallel to the first oxygen supply pipe 2. The second oxygen supply pipe 9 can supply oxygen into the reverberatory furnace, thereby increasing the oxygen content in the reverberatory furnace and further improving the combustion effect. In addition, a second flame detector 10 is also provided inside the burner brick 1, which is located between the first oxygen supply pipe 2 and the second oxygen supply pipe and is arranged parallel to the first oxygen supply pipe 2. Furthermore, the first oxygen supply pipe 2, the second oxygen supply pipe 9, the first flame detector 7 and the second flame detector 10 are located in the same vertical plane.

[0017] The method of using this utility model is as follows:

[0018] First, oxygen is introduced into the reverberatory furnace through the first oxygen supply pipe 2 and the second oxygen supply pipe 9, and the oxygen pressure in the first oxygen supply pipe 2 and the second oxygen supply pipe 9 is adjusted to be between 50 kPa and 0.6 MPa. By setting the corresponding pressure and ensuring the speed of oxygen injection, the oxygen is dispersed in the reverberatory furnace.

[0019] The oxygen supply in the first oxygen supply pipe 2 and the second oxygen supply pipe 9 is adjusted so that the oxygen supply in the first oxygen supply pipe 2 is 20% of the total oxygen supply and the oxygen supply in the second oxygen supply pipe 9 is 80% of the total oxygen supply. Since the second oxygen supply pipe 9 is inclined downward, the oxygen input into the reverberatory furnace through the second oxygen supply pipe 9 can be fully distributed in the reverberatory furnace, ensuring that the gas in all parts of the reverberatory furnace is fully combusted. Since the oxygen input into the reverberatory furnace through the first oxygen supply pipe 2 can be immediately mixed with the gas, the ignition success rate can be effectively improved.

[0020] Gas is introduced into the reverberatory furnace through gas pipe 5. Natural gas or coal gas, or other conventional gas, can be used. Then, an electronic igniter 8 is used for ignition. Since the first oxygen supply pipe 2 and the second oxygen supply pipe 9 are inclined downwards, the introduced gas is sprayed downwards and can be quickly ignited by the electronic igniter 8 below, resulting in a high ignition success rate. When the gas is burned in the reverberatory furnace, it mixes with the oxygen introduced through the second oxygen supply pipe 9, resulting in good combustion. During the combustion process, the combustion status in the furnace is detected by the first flame detector 7 and the second flame detector 10, which provides more accurate detection results and effectively prevents false detections. When the flame in the reverberatory furnace goes out, the supply of oxygen and gas can be stopped immediately.
