What are the reasons for the high furnace temperature in coal water slurry gasifiers?
Thread Content
The slurry flow rate is low, the oxygen flow rate is high, resulting in a high oxygen-to-coal ratio; the slurry concentration is low. After adjustments to the production load, the decrease in slurry flow rate is minimal, which leads to a high oxygen-to-coal ratio
I don’t know what the original poster is trying to convey with this post – what temperature is considered low? The furnace temperature in gasification furnaces is always above 1300 degrees.
Be especially careful to check whether the slurry flow meter is indicating a high value, which could be causing the furnace temperature to rise! !
One of the reasons for the high temperature in the gasifier furnace is high oxygen consumption
A high temperature in the gasifier furnace indicates a high oxygen-to-coal ratio
Worn or detached refractory bricks, high oxygen-to-coal ratio, misaligned nozzles, false thermocouple readings, low slurry concentration, and so on
