Analysis of gas composition in Texaco gasifiers
Thread Content
The methane content in the gas produced by the Texaco gasifier is relatively high; can it reach 6,000 ppm? What’s the reason for this, and are there any solutions?
It’s not possible to reach 6000 ppm in production; if such a level is indeed achieved, there must be some issue with the operating conditions. Check the methane meter, and also examine the quality of the coal, the reaction temperature in the gasifier, and the ratio of central oxygen.
The ash fusion point is 1184, the operating temperature is around 1250, and the central oxygen content is 15.6
I wonder what the burner pressure difference is? If the burner pressure difference and epoxy pressure difference are a bit high, it is recommended to increase the central oxygen ratio to 17%
During the operation of the gasifier, the methane content is merely a reference value. Check whether the trend is continuous or changes suddenly, and also observe whether there are fluctuations in the gas composition. If the levels of CO and H2 fluctuate significantly, it indicates that the temperature of the gasification furnace is too low; in such cases, the oxygen-to-coal ratio can be increased appropriately.
