Aspen Fired Heater – Firebox Models

Long Furnace Model (LFM)

− More realistic variation in combustiongas temperature

− Hence variation of heat flux on tubes

− Hence tube metal temperature

− Needs burner heat release characteristic

Well-Stirred Model (WSM)

− Considers single combustion gas temperature

− Hot gas at exit from firebox belowmean radiating temperature

− Hottel model

• Proportional to firebox load

To model operating heater can specify bridge-wall temperature

Aspen Fired Heater – Flow Stability Warnings

Warnings for:

Slug flow in firebox

Slug flow in convection bank

Two-phase flow at exit from two-path convection bank

Based on HTFS two-phase flow patterns

Avoid flow instabilities (pre-cursors to tube over-temperature and/or coking)

Aspen Fired HeaterUser-specified operational limits

Specify limits for

Firebox tube temperature – avoid tube failure

Firebox tube heat flux– avoid tube failure, avoid coking

Firebox process fluid outlet temperature– Avoid coking

Convection section fluid outlet temperature– Avoid acid gas condensation

Convection section gas velocity

Convection section gas pressure drop

Aspen Fired Heater V7.2 – Improvements

Improved gas emissivity model

– Improved 4-grey gas emissivity model

Option to select peak tube temperature calculation methods

– New “Adjusted Heat Flux Ratio” better for very high tube temperatures

Changes to input and output items and some calculation defaults

– In convection banks, radiative heat transfer is now “on” by default

Aspen Fired Heater V7.3 – Improvements

Specification of fouling factors for tube-groups and convection banks

– Tube-side and gas-side

fouling factors can now be

specified separately

for each tube-group and

convection bank

Additional correlations for gas-side heat transfer

– An option to select the ESCOA or HTFS3A correlations in addition to the pre-existing PFR correlation for gas-side heat transfer to high finned tubes
