In fields such as industrial production, hot – air furnaces provide a stable heat source for various processes. The hot – air furnaces of Hanyu Boiler are highly recognized for their advanced technology, reliable performance, and high – quality materials. Standardized operation and meticulous maintenance are the keys to ensuring their long – term, efficient, and stable operation.
I. Operating Specifications
1. Pre – startup Inspection Before startup, conduct a comprehensive inspection. Open the furnace door to check that there are no foreign objects in the furnace chamber. Ensure that the components of the burner are firmly connected, and there are no leaks in the oil and gas pipelines (which can be detected with soapy water). Confirm that the fan impeller rotates flexibly, the belt has the right tightness, and instruments like thermometers and pressure gauges can display data normally.
2. Startup Procedure After ensuring no abnormalities in the inspection, start the fan and let it run for a few minutes to expel cold air. Operate according to the fuel type. For fuel – fired units, start the oil pump and adjust the oil pressure properly. For gas – fired units, open the valve and adjust the pressure to the specified range. Then start the ignition device, gradually adjusting from a small flame to a large one to smoothly regulate the combustion power. Observe the flame closely during ignition. If ignition fails, immediately close the fuel valve, ventilate for 5 – 10 minutes, find out the cause, and then relight. Do not relight blindly multiple times to prevent explosion.
3. Monitoring during Operation During operation, closely monitor key parameters. Control the temperature of the hot – air outlet and the furnace chamber. Keep the furnace chamber temperature within the range specified in the manual. Adjust or troubleshoot in a timely manner when the temperature is abnormal. Monitor the fuel supply pressure and the hot – air duct air pressure to ensure stability. Pay attention to the operating sounds of the fan and burner. Shut down the machine immediately for inspection if there are abnormal noises.
4. Shutdown Operation When shutting down, first reduce the power of the burner. When the furnace chamber temperature drops to [specific temperature value], close the fuel valve. Let the fan run for a while to exhaust the remaining heat, and finally turn off the fan and electrical power supply. If the furnace is to be out of use for a long time, drain the remaining fuel and conduct a comprehensive cleaning and maintenance of the equipment.
II. Key Points of Daily Maintenance
1. Cleaning After the equipment cools down, wipe the surface of the furnace body daily to remove dust and oil stains. Clean the ash and slag in the furnace chamber at least once a week, and increase the frequency when the fuel has a high ash content. Regularly clean the dust in the hot – air pipeline, and deeply clean the nozzles and burners of the burner at least once a month to prevent blockage.
2. Sealing Inspection Regularly check the gaskets at parts such as the furnace door, observation holes, and air duct connection ports. Replace them promptly if they are aged or damaged. Use professional instruments to detect the sealing of gas or fuel pipelines and repair any leaks immediately.
3. Component Maintenance
Burner Maintenance: Regularly clean the carbon deposits on the electrodes and ignition needles. Check the fan impeller and motor. Replace severely worn parts in a timely manner. Add lubricating oil to the transmission parts according to the manual. Regularly debug the burner and adjust the air – door opening and fuel – supply ratio according to the fuel characteristics and combustion conditions.
Fan Maintenance: Regularly check the fan impeller. Repair or replace it if it is deformed or worn. Adjust the belt tightness, pay attention to the motor current and temperature, and add grease to the motor bearings regularly. Conduct a comprehensive maintenance once every [specific operating duration].
Safety Accessory Maintenance: Manually discharge the safety valve at least once a month. Calibrate the pressure gauge and thermometer every six months. Check the connectivity of the connecting pipelines and handle any problems promptly. Hanyu Boiler is customer – oriented, providing high – quality products and services.
