  • Project or process control engineers in refineries or petrochemical plants, involved in furnace design and performance follow-up.

Level : Advanced

Course Content


      • Different types of furnaces and selection criteria.
      • Furnace construction and design codes. Heat Distribution & Furnace efficiency.
      • Process conditions: fluid characteristics, operating conditions, required efficiency.
      • Consequences on the furnace technology and tube coil material.
      • Insulating material: main characteristics, installation and use.

      • Efficiency of tubular furnaces: design and operating parameters. Different types of burners, selection criteria, combustion performance and flame length. Impact on fuel consumption and operating costs. Pollutant characteristics: Impact of fuel quality and operating conditions on pollutant emissions. Scope for reducing emissions (CO2, NOx, SOx…).

      • Process study: furnace type selection. International standards and codes
      • Process data: process and auxiliary fluids (water-steam, etc.), operating conditions, efficiency, furnace duty, allowable heat losses, process constraints (coke formation, thermal degradation, etc.).
      • Fuel selection: combustion mass and heat balance.
      • Heat exchange area calculation: heat transfer in the radiant and the convection zone, mean/maximum heat flux.
      • Tube skin temperature and flue gas temperature estimate.

      • Construction codes and rules relating to safety (peepholes, explosion doors, access, fire protection).
      • Safety and control system on tube coil. Operating constraints.
      • Safety specifications on heaters, combustion, fuel circuits.
      • Air and flue gas circulation: natural and forced draft, control and safety system.
      • Recommendations for a Safe & Reliable operation.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • list the main industrial issues of furnace technology, operating conditions and constraints,
  • structure process data and define key criteria for furnace design,
  • identify pollution sources and ways to reduce emissions,
  • specify safety equipment to install on furnace and on different circuits (process, fuels, flue gas…).

Ways & Means

  • Course delivered by IFP Training experts and furnace design engineers from Heurtey Petrochem SA.
  • Case study used throughout the course to design the main characteristics of radiant and convection zones.
