Judging furnace temperature levels
Thread Content
After a thermocouple failure in a Texaco furnace, which is more accurate for determining the furnace temperature: carbon dioxide or methane?
After a fault occurs with the furnace thermocouple, one can only rely on checking the combustion of the flame and the condition of the furnace chamber to make a judgment
Looking at the flame inside from the nozzle, it is quite bright and white, which indicates that the furnace temperature is high
In fact, when assessing the furnace temperature, one cannot rely on just one indicator; it is necessary to consider various factors together. Regarding the issue you mentioned, methane is generally more sensitive as an indicator, but it is also important to take other components into account to check for any inconsistencies in the parameters
What was said upstairs is correct; in chemical processing, one should never rely on just one parameter – analysis based on multiple parameters is necessary.
Methane is more accurate; the higher the temperature, the lower the methane content
It is determined by many factors, such as other furnace temperature measurement points, methane, carbon dioxide, and slag shape
Looking at methane levels, higher furnace temperatures result in lower methane levels. By combining this with data from on-site sampling analyses, it is also possible to examine the oxygen-to-carbon ratio, which is proportional to the furnace temperature. Additionally, the gas temperature can be determined, allowing for judgments from multiple perspectives
1. Based on the curve graph, methane can be determined quickly; carbon dioxide has more influencing factors and its determination is less accurate. 2. The ultimate determination depends on the slag morphology when the coal quality is in a stable state
