Who should take this course
Operators, panel operators, supervisors and plant managers of refining chemical and petrochemical plants involved in furnace operation. Engineers and supervisors concerned with various safety optimization and operating issues of furnaces.
Furnace construction and operating conditions. Different types of furnace and their functions. Operating conditions. Distribution of heat influence of operating conditions. Efficiency of energy recovery. Estimation rule parameters governing furnace efficiency scope and limitations for improving furnace efficiency.
Construction of heat exchange areas and refractory materials:
- Tube bundle arrangement insulation type of materials used and operating limits. Combustion - Burners
- Stoichiometric air/fuel ratio heating value liquid and gas fuel characteristics liquid spray.
- Fuel and air supply and mixture burner operation low NOx burner characteristics.
