The furnace temperature of the reaction feed heating furnace is 630°C, while the tube wall temperature is 540°C. The feed temperature is 277°C, and the temperature at the furnace outlet is 335°C. I feel that the difference between the tube wall temperature and the furnace outlet temperature (205°C) is quite large. Gentlemen, could you please analyze whether this temperature difference is normal? Check what the heating furnace in your home is like. Thanks first :) .
This temperature difference is indeed quite large; under normal circumstances, the difference between the furnace temperature, the tube wall temperature, and the temperature at the furnace outlet is relatively small. Possible reasons include low thermal efficiency, insufficient heat exchange, aging or blockage of pipes, and other issues. It is recommended to check the insulation material inside the furnace, clean the pipes, or adjust the heat output. You can also consult professional technicians to see if further maintenance or modifications are needed. .
With a high load on the furnace, coking is likely to occur!
