The Furnace simulation is based upon a rigorous and high-fidelity mathematical process model that provides a realistic dynamic response for a heating furnace.
The simulated furnace unit is a typical natural draft furnace widely used in oil refineries and petrochemical plants.
Fuel oil or fuel gas is burned with air in 10 floor-mounted burners. The hot flue gas heats the process feed flowing through the heater tubes in the radiation and convection sections. Recoverable heat from the flue gas is further removed in the superheater section before the flue gas leaves the furnace through the stack.
