Embodiment 2

[0032] Embodiment 2: the combustion method of multi-oxygen gas combustion device, carry out the following steps:

[0033] 1) Detect and adjust the oxygen supply system:

[0034] (1) Adjust and stabilize the oxygen supply pressure: adjust the pressure stabilizing valve to stabilize the oxygen pressure supplied by the oxygen supply system within the design pressure range, which is 50KPa; adjust with the output pressure of the oxygen supply equipment and the pressure of the oxygen pipeline, Ensure that the oxygen pressure of the combustion device is stable;

[0035] (2) Adjust oxygen flow: the controller adjusts the oxygen supply through the primary oxygen flow meter, primary oxygen regulating valve, secondary oxygen flow meter, and secondary oxygen regulating valve; Oxygen accounts for 80% of the total oxygen;

[0036] 2) PLC control function detection: Through the oxygen pressure transmitter and flowmeter, the change of oxygen pressure and flow is transmitted to the PLC contr...

Abstract

The invention discloses an oxygen-rich gas combustion device. The oxygen-rich gas combustion device is provided with a combustion body, wherein the combustion body is provided with a burner block, and a gas spray gun and an oxygen spray gun are arranged in the burner block; the oxygen spray gun is provided with a primary oxygen spray gun and a secondary oxygen spray gun, and gas spray gun and the oxygen spray gun are arranged on a longitudinal cross section in the burner block at intervals; the gas spray gun is horizontally or slightly upward-obliquely arranged, and the front ends of a gun body of the primary oxygen spray gun and a gun body of the secondary oxygen spray gun are inclined downwards for 1 to 30 degrees; a gas inlet end of the gas spray gun is connected with a gas supply system, and the primary and secondary oxygen spray guns are respectively connected with a pure oxygen supply system; the burner block is also provided with a fire observation hole, a flame detector and an ignition gun. A combustion method of the combustion device comprises the following steps: 1, detecting and adjusting the oxygen supply system; 2, detecting a control function of the PLC; 3, interlock controlling the test; 4, setting a temperature, a gas normal operation value and an oxygen normal operation value; 5, starting and running. The oxygen-rich gas combustion device is applicable to kilns, smelting furnaces, anode furnaces, reverberatory furnaces, dore furnaces and the like in various industries and can improve the combustion efficiency, save the fuel, prolong the service life of the burner block and the kiln and reduce the exhausted smoke pollution.

Description

technical field [0001] The invention relates to an industrial gas combustion device, which belongs to the field of thermal energy engineering, specifically a brand-new combustion device for burning gas fuel and pure oxygen together, and is suitable for various industrial kilns, smelting furnaces, anode furnaces, reverberatory furnaces, separation furnaces, etc. Silver stove etc. Background technique [0002] A large number of burners are used in the production of the industrial field. It is one of the main equipment for energy consumption, carbon emission and environmental pollution. Its efficiency directly affects the effect of energy utilization and environmental protection. Therefore, people have attached great importance to the improvement of burner technology for a long time. Most of the burners currently used are air-assisted combustion. During the combustion process, a large amount of N 2 It is heated into high-temperature flue gas and discharged, which not only was...
