The blast furnace gas burner is simple installation, easy to operate, and good self-control performance. Energy saving and environmental protection. Let's see which key parts and inspection requirements for daily burner checks and maintenance
What are the key parts and inspection requirements for daily burner inspection and maintenance?
Compressed air - a lot of low nitrogen burners require compressed air to function properly. First check whether the compressor can provide the pressure required for a low nitrogen burner. Clean all the filters on the line, check if there is a leak in the pipeline, if you should fix it in time. a. Burning / atomized air blower - Check if the burning or atomized air blower entrance is installed to install a protective device, whether the working environment is required. Fix the leakage and damage of the fan shell. b. Observe the operation of the blade, see if there is too much noise and vibration, if there is an elimination of the blade. Check the connecting tube between the air inlet and the air inlet of low nitrogen burner, and repair the possible leak. For the belt drive, the bumper is performed regularly to lubricate the oil on the bearing and tighten the belt. It is determined that the blower can generate rated pressure and detect current intensity. Clean and lubricate the air valve connection, adjust whether the valve is smooth. Burner manufacturer c. Main fan - check whether the entrance to the main fan is installed, whether the working environment is required, and the leak on the fan is repaired. When the blade operation is observed, see if there is too much noise and vibration, and if there are these phenomena, it can be eliminated by adjusting the blades. Determine whether the required wind pressure is reached, cleans and lubricate the connection, adjust whether the air valve is smooth. d. induce air (exhaust) - Determine if the exhaust damper control is working properly and sets it correctly. Lubricate the damper connection to see if it is smooth. Check the wear of the damper blade. Ignition device - cleaning the ignition device, confirming whether the ignition electrode fire gap is normal. Components - Clean the flame detector, determine if its observation position is suitable, whether it is properly cooled. e. The maintenance of the coordinated burner of the burner and other parts of the system includes the commissioning of the burner, and the commissioning of the burner will produce higher work efficiency. The portable combustion analyzer provides accurate information of the combustor working condition. A typical combustor debugging method includes fuel analysis and a series of regulations that enable the burner to achieve a good operation performance in the case of holding the combustion power. Basic debugging can be completed within one day or less, and completed before various detection. After the complete burner maintenance procedure is completed, it is especially important in the initiality of the equipment investment operation. The debug burner should be carried out under normal conditions. Fuel samples should be extracted in the fuel barrel, so that the combustor work is accurately described. Debugging to a low nitrogen burner is carried out according to the sampling information of the combustion flue gas. The combustor is adjusted to air and fuel will affect flue gas emissions, and the flue gas ingredient can be studied and the efficiency of combustion is analyzed. The combustion products are listed in the following tables and the causes thereof. Regular burner maintenance procedures are necessary to avoid downtime and extend the life of the combustion system.
