Combustion in Boilers and Furnaces

What will I learn?
This course focuses on recent developments in burner design for process heating applications including:

  • boilers
  • furnaces
  • refinery operations
  • power plant
  • CHP schemes
  • minerals processing kilns
  • process plant.

Particular emphasis is given to combustion aerodynamics and its influence on burner design, low NOx burner design and emission reduction techniques including reburn, SNCR, SCR and NOx storage techniques. These aspects are examined in relation to:

  • large natural gas burners
  • pulverised coal firing
  • refinery burners
  • heavy fuel oil burners
  • flameless combustion
  • waste and bio-fuel firing
  • oxy-fuel firing
  • fluidised bed combustion.

Large scale burner testing and the role of CFD in burner design are also covered.

How will I benefit?
You’ll benefit from a broad introduction to combustion in boilers and furnaces. You’ll come away better informed and more knowledgeable with industrial examples.

Day 1: Boiler and furnace combustion and aerodynamics

  • Fundamentals: stoichiometry, excess air, CO and NOx and flame radiation
  • Enclosed flow furnace aerodynamics
  • Free jet theories and swirling jets – their application to furnaces and the prediction of flame lengths and the number of burners for boiler applications
  • CO emissions
  • Fundamentals of low NOx burners
  • Low excess air low NOx burners.

Day 2: Low NOx burner design and CFD use in burner design

  • Emissions regulations for combustion in boilers and furnaces
  • Internal and external flue gas recirculation for NOx control and flameless combustion
  • Refinery burners, including ultra low NOx burners, and process heaters
  • Application of CFD to power station burner and furnace design
  • Practical application of CFD to solve combustion problems on fired heaters
  • Burner applications in the chemical industry.

Day 3: Boiler and furnace fuels

  • Liquid fuel combustion and fuel properties
  • Fuel properties: gaseous (natural gas, LPG, biogas and gasified coal)
  • Natural gas process burners for low NOx
  • Coal as fuel in boilers and furnaces
  • Burner air-gas ratio control
  • Oxy/fuel burners
  • Bio and waste derived oils
  • Co-firing with bio-fuels.

Day 4: Industrial burners

  • Testing and development of low NOx burners
  • Oxy/fuel and FGR for carbon capture
  • Burners for mineral processing kilns
  • NOx emissions control for coal-fired boilers – technology layering and advanced reburning
  • Selective non-catalytic reduction/selective catalytic reduction
  • Mercury emissions control technologies for coal-fired boilers
  • Boiler optimisation.

Day 5: Coal combustion fundamentals and fluidised beds

  • Fireside corrosion, slagging and fouling
  • Boiler efficiency determination and control
  • Pulverised coal and char burnout fundamentals
  • Introduction to theoretical model of char particle combustion
  • Combustion rates and burning times at various temperature regimes
  • Burning time for a suspension of polysized coal particles in a practical furnace
  • Fluidised bed combustion.

The 2016 course programme and leaflet will be available approximately 3 months prior to the course. However, you can view and download the 2015 course details for further information by clicking the course leaflet and course programme link. 

This course is designed to provide training on the most recent developments in burner technology. It’s for you if you’re a recent graduate involved in combustion engineering, a burner designer or manufacturer. It’ll also be of relevance if you’re responsible for combustion plant or new burner installation.
