When burning ammonia in a sulfur production furnace using sulfur, should one focus on the flame temperature or the furnace temperature?
Thread Content
In a sulfur production furnace using sulfur as raw material, steam is used to strip acidic gases (such as ammonia and hydrogen sulfide); the temperature in the furnace chamber must be at least 1250°C. I have three temperature measurement points here: one at the front for measuring the flame temperature with an infrared sensor, one in the middle using a thermocouple, and another at the back also using a thermocouple. When operating the furnace, it is necessary to monitor either the flame temperature measured by the infrared sensor or the temperature of the furnace chamber. Please ask
Furnace temperature and tail temperature, as well as flame temperature, are used to monitor whether the combustion has stopped, right?
The key is to monitor the temperature at the front of the furnace, keeping it above 1300°C to ensure effective ammonia combustion
