What is the reason for the high temperature of the furnace skin in the sulfur recovery incinerator? The local temperature of the furnace skin reaches 270℃.

Take your temperature carefully, it doesn't matter if the highest point is only 300.

The current temperature is 294°C. It is suspected that smoke has entered the expansion gap of the lining. Yesterday it was 290℃. I guess I have to stop the car and not repair it. Heroes, do you still know the reason?

Is the insulation not done well? High temperatures will harm employees.

Observe more to see if the temperature will continue to rise. It doesn't matter where the temperature rises. The reason is either the inner lining falling off or the lining cracking. Based on your current situation, cracking is more likely. If the temperature does not continue to rise, wait until the company shuts down to repair it. If the temperature continues to rise, stop the furnace for repairs in time. The outer shell temperature should not exceed 400°C.

It depends on your internal temperature. If the internal temperature is around 1200 degrees, 270 degrees is not considered high. If it exceeds 300 degrees, you need to pay more attention.

Is the refractory mud falling off? It is recommended to open the manhole to check when production is stopped for maintenance. Also, when heating or cooling, the rate of heating and cooling must be controlled. Excessive temperature rise or cooling may cause the refractory mud to crack and fall off.

Reply 1# Snow Piao Paradise This situation must be a serious problem with your incinerator. 1. The lining of the incinerator has fallen off partially. 2. The lining gap is not widened within the normal range, causing the flue gas to radiate directly through the gap to the furnace wall. 3. The local excessive height is at the thermocouple, manhole, or fire hole. These lining problems are prone to occur. 4. During normal operation , the incinerator experienced a large temperature rise and fall, causing some lining damage. 5. A large amount of water entered the incinerator during operation. For example, if the purified exhaust gas was seriously contaminated with water, or a large amount of water accumulated in the exhaust pipeline suddenly poured into the incinerator, causing lining damage. 6. During the accident, a large amount of water condensed in the purified exhaust pipeline, and water was brought into the furnace during the return to normal process at the end of the accident.

Partially or completely? If it is localized, it may be a lining problem. If the entire shell temperature rises, you need to check the furnace temperature. Is there a problem with the air distribution?

A large amount of water enters the incinerator during operation. For example, the purified exhaust gas is seriously contaminated with water, or a large amount of water accumulated in the exhaust pipeline suddenly pours into the incinerator, causing damage to the lining.

The lining must have fallen off. Every time we perform maintenance, we open the manhole and drill into the furnace to check. We plug the larger gaps with refractory cotton and then paste them with refractory mud! Our incinerator furnace temperature control does not exceed 600 degrees Celsius!
