Fundamental of Furnace Operation

Introduction

  • The combustion of fuel in the process industry is Costly. It is also the largest single contributor to environmental emissions. Good furnace operation therefore still remains one of the areas that require skilled intervention in order to maintain efficient performance.
  • The Course concentrates on energy minimization by all reasonable cost-effective means and introduces the latest advances in "low NOx” burner technology on the market.
  • The course covers all the features of cracking furnaces that are used in Ethylene cracking

Objectives

    To provide in-depth knowledge of furnace operation in the petroleum and petrochemical industries, at the end of the course, participants:

    • have a better knowledge of industrial combustion phenomena
    • manage on stream furnace operation rules in safety
    • are able to diagnose bad quality combustion from flue gas analysis and flame study and bring remedy to it
    • know the main step of a furnace start-up procedure

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.

Who Should Attend?

Operators, panel operators, and supervisors of refinery, chemical and petrochemical plants involved in furnace Operation. Graduate engineers and technical supervisory staff concerned by different aspects of the operation of These types of equipment.

Course Outline

Furnace Construction and Operating

  • Different types of furnaces and their functions.
  • Operating conditions. Distribution of heat supplied, 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.

Combustion-Burners

  • Combustion conditions: stoechiometric air/fuel ratio, heating value, liquid and gas fuel characteristics, liquid spray.
  • Burners: fuel and air supply and mixture, burner operation, low NOx burners characteristics.
  • Combustion quality: analysis of the oxygen and the unburned material in the flue gases, control of the combustion air flow rate, air/fuel ratio control.
  • Combustion safety: flame detection, control and safety devices on the fuel circuits.
  • Air and flue gas circulation: natural draft, forced draft, pressure differential control, automatic safety devices. Damper or forced draft fan role. Impact of a furnace positive pressure.
  • Application: natural and forced draft pressure profile drawing. Presentation of different types of burners and spraying systems.

Heat Transfer and Tube Bundle

  • Heat transfer to the tube bundle: heat flux, conduction, convection and radiation, parameters governing heat transfer, tube skin temperature, type of fuel burned, tube temperatures, fouling effects.
  • Division of the heated fluid into several passes: control of partition, low flow rate safety systems.
  • Heating control: process fluid outlet temperature, fuel flow rate control.
  • Application: furnace temperature profile and heat recovery distribution as a function of fuel burned and combustion air excess.

Furnace Operation

  • On-stream furnace operations: monitoring of combustion and heating. Modifying operating conditions. Analysis of disturbances. Key points for safe operation, operating conditions control and follow-up.
  • Startup and shutdown: preparation, safe ignition procedures, ignition after a short shutdown, normal shutdown, emergency shutdown.
  • Incidents: explosive atmosphere in the radiation zone, tube rupture, unbalancing of the heat,
  • Diagnostic facilities; ways of solving problems
