What are the main maintenance tasks for Texaco gasifiers on a regular basis?

I would like to ask the experienced colleagues: after operating for a certain period of time, Texaco gasifiers need to be shut down for maintenance. What are the main tasks involved in this maintenance? Thank you

Personally, I think the nozzle should be an item that must be checked
All parts of the system that are unstable or have experienced problems before parking need to be inspected and maintained. Generally, the internal components of the gasification furnace should be checked, as well as valves and the associated pumps, etc. In terms of electrical and instrumentation equipment, thermocouples are of key importance; other aspects require inspection based on time elapsed and the duration of use……
Burner: 30 days; Cone-bottom refractory bricks: 4000 hours; Straight-tube refractory bricks: 8000–12000 hours; Diaphragm of high-pressure slurry pump: 8000 hours; Valves: 6000 hours; Hopper valves: 12000–15000 hours; High-pressure oxygen and nitrogen valves: 12000 hours. Also, the filler for the slag breaker – theoretical data. The most important aspects are the burner, temperature measurement points, as well as the inspection of refractory bricks and other internal components
Is there any blockage in the water inlet hole of the quenching ring?
The maintenance tasks mainly involve addressing various issues that arise in equipment and pipelines during normal operation, as well as correcting the installation methods of those equipment and pipelines that do not meet the process requirements.
Equipment maintenance is carried out according to a schedule. In the chemical industry, cleaning is primarily focused on pipelines that carry dirty fluids such as quench water, black water, gray water, and coal slurry. This includes flow meters, pressure gauges, filters, quench rings, venturi devices, etc. The thickness of the furnace bricks needs to be checked only after the gasifier has been in operation for about a year, when there is a risk of overheating of the gasifier’s walls............
Cleaning of the black water pipeline after parking, as well as cleaning of the quench water filter; in addition, maintenance of burners, quenching rings, high and low temperature thermocouples, furnace bricks, slag skimmers, and mechanical pumps
Firstly, for the equipment, pipelines, and valves that experience problems during operation, they need to be carefully inspected after shutdown. Next are the burners, and then there are various moving equipment such as pumps and motors
