What Issues Should Be Paid Attention To in Gas Trolley Furnace System?

Various burners heat the gas-fired trolley furnace to a temperature of 1200°C. 2. The gas-fired trolley furnace utilizes high-speed burners with a high ejection velocity of up to 100 m/s. The burners are evenly distributed on both sides, effectively stirring the furnace atmosphere and maintaining a uniform temperature. The gas burners offer continuous proportional combustion. An actuator adjusts the air volume, and a proportional valve regulates the gas flow to achieve a consistent air-fuel ratio. Both the gas and air volumes are controlled by lower limits. Each burner's gas pipe is equipped with a control solenoid valve. Each burner is equipped with a complete, independent combustion controller featuring automatic ignition, flame detection, and fire alarms for automatic gas shutoff. This fully ensures the stability and safety of the combustion and temperature control system. 3. The burner system ensures complete combustion, fully utilizing the fuel. The use of zero-pressure control and fully sealed technology ensures zero pressure at the trolley-furnace interface (the sealing surface between the trolley and the furnace body), preventing gas leakage and cold air infiltration, ensuring efficient utilization of the heat generated by combustion. 4. The preheater adopts a GC-type shell-and-tube heat exchanger with spoiler insertion to increase the preheating temperature of the air. When the furnace temperature is 1000℃, the air temperature is preheated to 300-350℃. 5. The heat exchanger is designed with heat-resistant steel and stainless steel according to different temperatures, and the layout adopts homogenization and thermal stress elimination measures. 6. Control system. The full-fiber gas trolley furnace control system mainly adjusts and controls the flow rate of the gas pipeline of each furnace, the flow rate of flue gas and the dilution air volume through the detection of temperature and pressure in the furnace, and is equipped with a natural gas main quick shut-off device. 7. When the air, gas pressure and compressed air pressure do not meet the requirements, the combustion of the burner will not start, and it will be safely shut down if it is burning. 8. The top of the gas trolley furnace is equipped with a chimney installed with automatic furnace pressure control, butterfly valve, etc., which can adjust the cooling speed.
