Main steps for shutting down and restarting the pressure hot standby furnace in the Luchi pressurized gasification system

Parking steps: 1. Reduce the load on the gasifier, and decrease the coal feed rate as well as the flow rate of the oxidizer. 2. Disconnect the gas supply pipeline and close the relevant valves. 3. Gradually cool the furnace body and turn off the heating system. 4. Stop the circulation of materials inside the furnace to ensure that no gas is generated in the system. 5. Monitor the pressure inside the furnace and release pressure if necessary. Steps to start driving again: 1. Check that all instruments and equipment in the system are functioning properly to ensure safety. 2. Restart the heating system and raise the temperature to the vaporization temperature. 3. Open the necessary valves to restore the supply of coal powder and oxidizer. 4. Gradually increase the pressure and temperature inside the furnace to restore the gasification reaction. 5. Gradually increase the load until the gasifier reaches normal operating conditions. Please note that the specific steps must be followed in accordance with the detailed procedures established by the system to ensure safety and efficiency. .
