Gas Furnace Conclusion

As a new technology, pulse combustion has broad application prospects and can be widely used in ceramics, metallurgy, petrochemical and other industries. It will play a significant role in improving product quality, reducing fuel consumption and reducing pollution. It is an innovation in the automatic control of the industrial furnace industry and will become the development direction of industrial furnace combustion technology in the future.
1. The equipment uses various combustion gases as the medium and burns and heats through various burners, with a maximum temperature of 1200℃.
2. The furnace body skeleton is welded on-site by various large and medium-sized steel sections. The shell sealing plate is a color steel plate, and the high-aluminum all-fiber refractory spinning blanket module is the furnace lining, with obvious sealing and energy-saving effects.
3. The trolley skeleton is welded by a combination of various large I-beams, channel steels, angle steels and thick steel plates.
4. The trolley transmission adopts all wheels as driving wheels, which is reliable. The transmission system adopts the "three-in-one" motor-reducer installation method as shaft-mounted, with compact structure, firm assembly, flexible entry and exit, simple operation and convenient maintenance.
5. The refractory masonry of the trolley adopts a high-aluminum fixed brick structure, which has a good sealing effect with the furnace body and high compressive strength. The trolley surface is placed with pads for stacking workpieces. The trolley side plates are all cast parts to ensure that the car body does not deform and is durable. The sealing between the furnace car and the furnace lining adopts a refractory fiber sealing block electric push rod automatic compression structure. The opening and closing of the side seal is interlocked with the furnace car in and out.
6. The furnace door adopts a high-aluminum all-fiber refractory wire blanket and steel composite frame structure, electric hoist lifting, and the furnace door sealing mechanism adopts a long and short lever spring type automatic compression cam mechanism and a soft edge sealing device. Ensure that there is no friction up and down, easy, safe and reliable.
7. The chimney is equipped with automatic furnace pressure control, butterfly valve, etc., which can adjust the cooling speed.
8. High-speed burners are used for heating, evenly distributed on both sides. Continuous proportional adjustment of combustion. The actuator adjusts the air volume, and the proportional valve adjusts the gas volume to achieve air-fuel ratio combustion. The gas and air volume have lower limits. The gas pipe of each burner is equipped with a control solenoid valve. Each burner is equipped with an independent and complete combustion controller with automatic ignition, flame detection, and automatic gas cut-off of fire extinguishing alarm. This fully ensures the stability and safety of the combustion temperature control system.
9. Characteristics of burners
High-speed burners basically achieve complete combustion of fuel and combustion-supporting air in the combustion chamber. The high-temperature gas after combustion is ejected at a speed of 100m-150m/s, thereby enhancing convective heat transfer, promoting airflow circulation in the furnace, and achieving the purpose of uniform furnace temperature, so that the insulation is uniform at ≤±10℃.
