The temperature at the rear of the sulfur furnace in the sulfur plant has exceeded the design temperature; it is currently 500 degrees. May I ask why?

Now； My plant’s 20,000-ton sulfur unit can handle a full flow rate of 2,000 m³/h of clean acidic gas and 800 m³/h of ammonia-containing acidic gas. The temperature in the furnace of the sulfur production plant and ammonia burning furnace is 1300 degrees; since November, the temperature at the rear part of the furnace has remained high at 500 degrees, posing a safety risk to production. The preheating boiler is operating normally, producing steam using oxygenated water (approximately 7 tons/hour). Have any of you, fellow seafarers, encountered such problems during production?
It should be at full load! The temperature at the back of your cooler must be very high, right?
It’s overloaded; appropriately reduce the air-to-gas ratio to lower the steam generation pressure in the heat recovery steam generator.
