ABSTRACT:
An improved control system and method for maintaining the outlet temperature of a process fluid exiting from a process fluid coil located in the convection section of a boiler having a convection section and a radiant section. The improved control system and apparatus comprise means for measuring the inlet temperature and the flow rate of a process fluid to the process fluid coil and means for measuring the temperature of the process fluid at the outlet of the process fluid coil. The improved control method and apparatus also comprise a first means responsive to changes in the inlet temperatures and flow rate to vary the amount of flue gas recirculated from the convection section of the boiler to the radiant section and a second means responsive to changes in the outlet temperature of said process fluid to vary the amount of fuel feed to the combustion section of said boiler. A boiler in combination with the improved control system and apparatus is particularly useful in controlling the coil outlet temperature of a hydrocarbon process fluid and offers distinct advantages in heating the feed slurry to a coal liquefaction process.
