Regenerator top temperature
Thread Content
The temperature measurement point at the top of the regenerator is usually located at the highest temperature area. When heating with coke oven gas, for the regenerator with an upward airflow, should the measurement be taken immediately after the heat exchange, or five minutes after the exchange? I see two different versions; I hope someone experienced can help me figure this out! ! !
The temperature measurement point at the top of the regenerator is generally located at the highest temperature area. When heated with coke oven gas, measurements are taken in the regenerator of the upward airflow immediately after the exchange occurs. Because, when it drops, the temperature of the hot exhaust gases is transferred to the regenerator, raising its temperature; the regenerator reaches its highest temperature at the exact moment when it shifts from a downward trend to an upward one, and it’s at that time that temperature measurement should be taken. It would be ideal to be able to measure the temperature of the entire regenerator at once. If you take another measurement after five minutes, the temperature has already dropped; thus, the reading does not reflect the highest temperature reached.
Thank you! I learned it! One more question: When measuring the temperature at the top of the regenerator, is it the temperature of the wall surface at that location or the temperature of the gas there?
The purpose of measuring the temperature at the top of the regenerator is to prevent damage caused by excessively high temperatures there. This is why it is necessary to find the point with the highest temperature inside the heat storage chamber for measurement
