Description

Technical Field

[0001] This utility model relates to a device for controlling a gas-fired furnace regenerative burner in the forging industry, specifically a device for adjusting the flame of the regenerative burner according to the gas flow rate to ensure complete combustion. Background Technology

[0002] Regenerative burners in gas-fired furnaces are widely used in forging industry gas-fired furnaces due to their advantages of efficiently recovering heat from combustion products while preheating gas and combustion air, thus achieving high-efficiency combustion. Before a gas-fired furnace is put into use, the flame of each regenerative burner needs to be adjusted according to its power rating. Currently, flame adjustment for regenerative burners relies heavily on manual observation of flame color and state, which cannot achieve standardized control. Therefore, there is an urgent need for a device that can standardize the flame adjustment of regenerative burners. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device that can eliminate the influence of human factors and achieve standardized quantitative adjustment of the flame of a regenerative burner according to the gas flow rate.

[0004] The technical solution of this utility model is implemented as follows: A device for adjusting the flame of a regenerative burner according to the gas flow rate includes a pair of regenerative burners. A left regenerative body box and a right regenerative body box are respectively installed on the left and right regenerative burners. The right regenerative body box is connected to the outside ambient air through a combustion air manual regulating valve, a combustion air solenoid valve, and a pipeline. The right regenerative burner is connected to a gas solenoid valve through a pipeline. The right gas solenoid valve is connected to a right gas manual regulating valve through a pipeline. The right gas manual regulating valve is connected to a gas flow meter through a pipeline and a tee. The gas flow meter is connected to a gas source. While the right gas manual regulating valve is connected to the gas flow meter through the tee, it is also connected to the left gas manual regulating valve and the left gas solenoid valve. The left regenerative burner is connected to an exhaust solenoid valve and an exhaust manual regulating valve through a pipeline. The exhaust manual regulating valve discharges the flue gas through a pipeline.

[0005] The positive effects of the technical solution of this utility model are as follows: Compared with the traditional method of manually observing the flame color and state, the method of adjusting the flame of the regenerative burner of this utility model solves the problem of inaccurate and unquantifiable control of the gas flow rate for adjusting the flame of a single regenerative burner. At the same time, it avoids the problem of incomplete combustion caused by excessive flow during combustion of the regenerative burner, thereby improving combustion efficiency.

[0006] The opening of the regenerative burner gas solenoid valve is interlocked with the extinguishing of the ignition burner, ensuring that the regenerative burner gas solenoid valve cannot be opened after the ignition burner is extinguished. The manual regulating valve ensures stable opening after adjustment, preventing flow fluctuations under prolonged pressure. The instantaneous flow rate of the flow meter can be displayed in real time, facilitating accurate adjustment of the gas manual regulating valve. Attached Figure Description

[0009] like Figure 1 As shown, a device for adjusting the flame of a regenerative burner according to the gas flow rate includes a pair of regenerative burners. A left regenerative body box 10 and a right regenerative body box 4 are respectively installed on the left regenerative burner 8 and the right regenerative burner 9. The right regenerative body box 4 is connected to the outside ambient air through a combustion air manual regulating valve 1, a combustion air solenoid valve 13 and a pipeline. The right regenerative burner 9 is connected to a gas solenoid valve 3 through a pipeline. The right gas solenoid valve 3 is connected to a right gas manual regulating valve 2 through a pipeline. The right gas manual regulating valve 2 is connected to a gas flow meter 5 through a pipeline and a tee. The gas flow meter 5 is connected to a gas source. While the right gas manual regulating valve 2 is connected to the gas flow meter 5 through the tee, it is also connected to the left gas manual regulating valve 11 and the left gas solenoid valve 7. The left regenerative burner 8 is connected to a flue gas solenoid valve 12 and a flue gas manual regulating valve 6 through a pipeline. The flue gas manual regulating valve 6 discharges flue gas through a pipeline.

[0010] The method for adjusting the flame of the regenerative burner involves first opening the ignition burner to ensure a normal flame; then adjusting the manual adjustment valve 1 for combustion air and the manual adjustment valve 2 for right gas to 20% opening, opening the debugging interface, and manually opening the right gas solenoid valve 3 and the combustion air solenoid valve 13 to initiate combustion in the right regenerative burner 9. Observe the instantaneous flow rate of the gas flow meter 5 and adjust the manual gas adjustment valve according to 85% of the burner power to ensure the burner flow rate matches the burner power. Then observe the burner flame state and adjust the manual adjustment valve 1 for combustion air to ensure the flame is blue and fully combusted. The flame adjustment of the right regenerative burner 9 is now complete.

[0011] In this embodiment, the method for adjusting the flame of the regenerative burner is as follows: First, the burner power is set to P KW. Based on 85% of the burner power, the required natural gas flow rate is calculated as follows: Q natural gas = P * 85% / 10m³. The required coke oven gas flow rate is calculated as follows: Q coke oven gas = 2 * P * 85% / 10m³.

[0012] Specific example: The regenerative burner has a power of 1250KW. If the fuel is natural gas, then Qnatural gas = 1250 * 85% / 10m³ = 106.25m³. If the fuel is coke oven gas, then Qcoke oven gas = 2 * 1250 * 85% / 10m³ = 212.5m³. With the burner ignited, adjust the manual control valves for combustion air and gas to 20% open. Open the commissioning interface and manually open the burner's gas solenoid valve and combustion air solenoid valve to start combustion in the regenerative burner. Observe the instantaneous flow rate of the gas flow meter. If the fuel is natural gas, adjust the manual control valve for gas to an instantaneous flow rate of 106.25m³ / h. If the fuel is coke oven gas, adjust the manual control valve for gas to an instantaneous flow rate of 212.5m³ / h. Then observe the flame state and adjust the manual control valve for combustion air until the flame is blue. The flame adjustment of the regenerative burner is complete.
