How to deal with reaction distortion of thermocouples used to measure reaction temperature in the combustion chamber of a gasifier
Thread Content
How should reaction distortion caused by thermocouples used to measure the reaction temperature in the combustion chamber of a gasifier be addressed? I would appreciate some advice from everyone
It is possible that the ceramic tube is impure, resulting in reactions that cause other materials to adhere to the platinum-rhodium wire. Consider the issue of thermocouples.
It’s normal for it to get damaged; just operate based on other factors, such as the effective gas components and the oxygen-to-coal ratio. That device also breaks down frequently here
The furnace temperature is primarily determined by the methane content in the syngas; in addition, the temperature of the gasifier support plate, the temperature of the syngas exiting the gasifier quench chamber, the carbon dioxide content in the syngas, and the slag sample are also taken into consideration. :victory:
The furnace temperature is determined based on the parameters under normal operation, primarily by considering the methane content, and appropriate adjustments are made; maintenance is carried out after the system is shut down
It’s normal for the thermocouples in the gasification furnace to get damaged; they wear out after a short period of use, often right after the furnace starts operating. In terms of operation, one can only rely on parameters such as the oxygen-to-coal ratio, the composition of the syngas, the amount of coarse slag, and the pressure difference at the slag outlet to make judgments. The main temperature of the vaporizer is itself a reference value; why not take it into consideration during installation?
How is the distortion done? Temperature drift – is the temperature continuing to drop?
