How to introduce the desorbed gas from the PSA system into the converter

When introducing the PSA desorbed gas into the low-pressure burner of the converter as fuel, it is first necessary to ensure that the existing fuel gas supply system is stable and controllable. The specific steps are as follows: 1. Check the operating conditions of the conversion furnace to ensure it is running properly. 2. Gradually reduce the amount of gas (such as natural gas) used by the existing burner by slowly closing the gas supply valve, in order to decrease the flow rate of gas inside the burner. 3. At the same time, gradually open the valve connected to the PSA desorption gas line, slowly increasing the flow rate of the desorption gas to ensure that the total gas supply to the burner remains stable. 4. Monitor the furnace conditions and the operating parameters of the converter, and continuously adjust the ratio of desorbed gas to the original fuel gas until the original gas is completely replaced by the desorbed gas. 5. Throughout the switching process, monitor the combustion status of the burner as well as parameters such as pressure and temperature in the converter to ensure safe operation. 6. After completing the switch, continue to monitor the operation of the furnace to verify the conversion efficiency and the stability of the equipment. During the operation, be sure to follow the on-site safety procedures to ensure the safety of both the operators and the equipment. If necessary, consult relevant technical experts or contact the equipment manufacturer for guidance. .

Should each burner be adjusted individually, or should the main valves for the two fuel gases be adjusted directly?

Generally, it is recommended to adjust each burner individually first, as this allows for more precise control over the proportion of fuel gas and the combustion process, thereby avoiding instability in combustion or safety risks that may arise from adjusting the main valve directly. Here are the specific steps: 1. Select a burner to start with the adjustments, gradually reducing the amount of fuel gas used by that burner, while slowly increasing the supply of PSA desorption gas. 2. Observe the combustion of the burner after adjustment to ensure the flame is stable, with no abnormal noises or vibrations. 3. After confirming that one burner has been adjusted successfully and is operating stably, repeat this process one by one to adjust the other burners. 4. After all the burners have been adjusted, check the operating parameters of the entire converter system once again to ensure stable and safe operation as a whole. Using the method of adjusting burner by burner is a safer approach; it helps to gradually adapt to the new fuel gas combination and prevents accidents in the system caused by sudden and drastic changes. .

Thank you, I’ve learned a lot; it’s extremely professional.
