FRNC-5PC General Purpose Fired Heater Simulation Program
|
 |
FRNC-5PC is a rating program for general purpose fired
heaters. Based on user-supplied heater geometry and process information,
the program calculates operating parameters such as firing rate, heater
efficiency, tube skin temperatures and required tube thicknesses,
gas-side temperatures and draft, process temperatures, pressure drop and
flow regimes, heat duties and fluxes, and much more.
FRNC-5PC simulates most heater types, coil configurations, tube and fin
types, and external transfer lines. FRNC-5PC can simulate the heat
recovery sections of any types of furnaces, boilers and turbines.
FRNC-5PC has user-friendly graphical input systems for either DOS (via
Windows 3.1) or Windows 95/98/NT/2000 operating systems. The input systems
contain on-line help and input limit and error checking. |

FRNC-5PC contains an automatic stream property generator for common chemical
compounds and typical petroleum fractions. Users can optionally supply their own
stream property profiles. The program features International and US/English unit
systems for input and output.
Following are some of the many uses of FRNC-5PC:
 | Reduce Heater Operating Costs
 | Lower heater fuel consumption
| Evaluate air leakage, air preheaters and heat recovery coils |
|
| Increase Heater Capacity
| Identify thermal, hydraulic and draft limits
| Model process controls
| Minimize excess air for NOx control |
| |
| Evaluate Process Changes
| Stream rates, temperatures and compositions
| Steam injection
| Process stream flow regimes and vaporization
| HAZOPS and Process Safety Management reviews |
| | |
| Check New Heater Designs
| Optimize capital expenditures
| Determine firebox and overall heater efficiencies
| Evaluate most boiler types |
| |
| Minimize Unplanned Shutdowns
| Provide detailed tube skin temperature and tubewall thickness profiles
| Evaluate fouling and coking effects
| Train engineers to troubleshoot heaters |
