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. The input systems contain on-line help and input limit and error checking.
