Aspen Fired Heater

Simulate and Optimize Fired Process Heaters.

Aspen Fired HeaterTM is a simulation and rating program for modeling a complete fired process heater system, including both radiant and convection sections. Troubleshoot process furnace operational performance to maximize efficiency or identify potential for tube burnout or excessive coking.

Model multiple firebox types.

Firebox radiation modeling uses either a simple “well stirred” model or a more detailed zone model. It supports cylindrical fireboxes with helical coils or vertical tubes; cabin or box heaters, with horizontal or vertical tubes, either refractory backed or as a single or double central row, and optionally with roof tubes. With Aspen Fired Heater, you can model process furnaces with single or twin cabin fireboxes.
