Fired Heaters

An engineering module for thermal calculations of fired process heaters of various designs – from heat balances and fuel consumption to heat-transfer analysis and operating performance assessment

Heater types and designs

Tubular fired process heaters – vertical cylindrical, box-type and other configurations with different coil and burner arrangements

Heat balance and fuel

Calculation of heat duty, fuel consumption, flue gas composition and efficiency, accounting for excess air and heat losses

Radiation and convection

Modeling heat transfer in radiant and convection sections, heat flux distribution and fluid heating in coils

Operating conditions and limits

Assessment of process-fluid and tube-wall temperatures, pressure drop and the effects of throughput, fuel composition and operating conditions
