Overview

Objectives:

  • To describe industrial combustion phenomena and calculate the air/fuel ratio for optimum combustion.
  • To identify bad-quality combustion from flue gas analysis and flame study, and implement corrective steps.
  • To list and apply the main steps of a furnace start-up procedure.
  • To recognize the main operating and material constraints for an optimal, safe and reliable furnace operation.

Description

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

  • Combustion conditions: stoichiometric air/fuel ratio, heating value, liquid and gas fuel characteristics, liquid spray.
  • Burners: fuel and air supply and mixture, burner operation, low NOx burner 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 furnace positive pressure.
  • Application:
  • Natural and forced draft pressure profile drawing.
  • Review of draft constraints.
  • Presentation of different types of burners and spraying systems.

Heat transfer and tube coil

  • 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 flowrate safety systems.
  • Heating control: process fluid outlet temperature, fuel flowrate control.
  • Most important furnace temperature and constraints: skin temperature, bridgewall temperature, limits and risk of overcoming
  • 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.
  • Start-up 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, etc.
  • Diagnostic facilities; troubleshooting.
  • Application:
  • Case study of furnaces incidents.
  • Start-up procedure study.

FAQs

Study method describes the format in which the course will be delivered. At Reed Courses, courses are delivered in a number of ways, including online courses, where the course content can be accessed online remotely, and classroom courses, where courses are delivered in person at a classroom venue.

CPD stands for Continuing Professional Development. If you work in certain professions or for certain companies, your employer may require you to complete a number of CPD hours or points, per year. You can find a range of CPD courses on Reed Courses, many of which can be completed online.

A regulated qualification is delivered by a learning institution which is regulated by a government body. In England, the government body which regulates courses is Ofqual. Ofqual regulated qualifications sit on the Regulated Qualifications Framework (RQF), which can help students understand how different qualifications in different fields compare to each other. The framework also helps students to understand what qualifications they need to progress towards a higher learning goal, such as a university degree or equivalent higher education award.

An endorsed course is a skills based course which has been checked over and approved by an independent awarding body. Endorsed courses are not regulated so do not result in a qualification - however, the student can usually purchase a certificate showing the awarding body's logo if they wish. Certain awarding bodies - such as Quality Licence Scheme and TQUK - have developed endorsement schemes as a way to help students select the best skills based courses for them.
