I need help understanding the reasons behind the interlock settings for shutting down the gasification furnace, and how the shutdown threshold value is determined

What trip interlocks are required for Texaco gasification? How are interlock values determined? Why set it? The reason for setting it
As mentioned above, the technical patent agency will provide recommended interlock values, which can then be fine-tuned based on actual conditions and relevant experience. If there is no relevant experience, one can initially use the interlock values provided by the technology patent holder, and make adjustments as appropriate during subsequent operation
Gasification technology provides an emergency shutdown interlock, mainly to protect the equipment.
Interlock systems are designed to ensure the intrinsic safety of the production process; whenever changes in certain process parameters can lead to equipment damage or casualties, the interlock system is activated to stop the operation of the equipment, close the feed valves, or open the vent valves.
The gasifier interlock is designed to prevent excessively high temperatures or too low flow rates
Changing the interlock values requires confirmation from the patent holder; it’s just like modifying something without permission, and no warranty will be provided
The purpose of interlock settings is to ensure the safe operation of the equipment, including the safety of both people and devices. Basis for setting interlock values: equipment structure and compressive and temperature resistance capabilities.
The determination of interlocking is related to the equipment’s temperature resistance and strength, as well as safety protections, and it is also connected to the operation of the process； A specific analysis is required based on the particular circumstances ； The protection of the gasification furnace includes monitoring the flow rate of coal slurry (coal powder), the pressure in the gasification furnace, the cooling water system of the burners, the oxygen flow rate, as well as the opening degree of the valves for coal slurry (coal powder) and oxygen.
