Maintenance of Supply Gas Elements at the Bottom of Regenerative Furnace
The Regenerative furnace is an essential unit in many industrial production processes. In order to maintain the efficiency of the Regenerative furnace, it is very important to maintain the supply gas elements at the bottom of the furnace. This paper will introduce the basis and principle of the supply gas elements of Regenerative furnace, and put forward the issues and methods of the elements maintenance.
Firstly, we will describe the equipment on the bottom of the Regenerative furnace and its function. There are generally three devices equipped on the bottom of Regenerative furnace, namely, blower, pressure regulating valve, and gas metering valve. The purpose of the blower is to provide sufficient air flow and pressure to keep the Regenerative furnace in a normal working condition. Pressure regulating valve is used to ensure that the air pressure reaches the required level. The gas metering valve is mainly used to control the flow rate of air entering the furnace and to achieve precise control of air supply.
Secondly, there are some issues in gas element maintenance in the process of Regenerative furnace’s operation. The main issues include leaking diaphragms, worn bearings, unnormal noise, sticking oil and dust, corrosion damage and low gas flow. If any of these problems occur, the function of the gas element will be affected, which in turn will affect the performance of the Regenerative furnace. Therefore, it is necessary to regularly maintain the gas elements of the Regenerative furnace.
Thirdly, there are several methods to maintain the Regenerative furnace’s supply gas elements in detail. Firstly, before the repair and inspection of the gas elements, it is necessary to cut off the power supply, and then clean the dirt on the element surface. Secondly, after taking off the gas element cover, it is necessary to check the function of the diaphragm switch. In addition, the inner and outer surface bearings must be lubricated as required. Thirdly, the rust, dust and oil accumulation in the insulation space must be removed every month. Fourthly, the seals should be checked and replaced Check the sealing performance of the sealing components regularly to prevent air leakage and avoid the high pressure inlet caused by the pressure difference. Fifthly, the pressure-regulating valve should be adjusted regularly. Finally, the gas metering valve should be operated and the gas flow rate should be adjusted regularly to make sure that the air supply to the furnace meets the requirements.
To sum up, the proper maintenance of Regenerative furnace supply gas elements is necessary to ensure the normal operation of the Regenerative furnace. Therefore, it is necessary to regularly maintain the three gas elements (blower, pressure regulating valve, and gas metering valve) at the bottom of the Regenerative furnace. Although the maintenance of the gas elements is simple and can improve the efficiency of the Regenerative furnace, it is still important to remind the operators and technicians to pay attention to the daily inspection and maintenance of the Regenerative furnace.
