There must be flow control when entering the furnace. The furnace outlet temperature is used to regulate the fuel flow rate.
The outlet temperature of the reboiler is linked in cascade with the fuel gas flow rate to control the bottom temperature of the distillation tower
Control is not sensitive to the furnace outlet temperature; it is recommended to control the outlet gasification rate.
The oxygen content in the furnace is sensitive to changes in the calorific value and pressure of the gas, and the oxygen content can be used to control the position of the gas valve.
