Additional notes on Fired Heater Thermal Design

• If results of thermal calculations are acceptable, then User should continue, if not, changes should be made, resave file, and rerun calulations.




• Two available input screens were not reviewed above, they are:
  1. Reference Data: This form is used to input User project information for identity of data.
  2. Thermal Design Factors: This form is used to set or tweak constants used or calculated in the thermal correlations. They should only be manipulated by a heater designer to account for deficiencies such as non-homogeneous radiant gas temperatures, or damaged or fouled fins in the convection section, etc.

     
     

• Please continue to review remaining calculations available.
