  21. Combustion ‘Combustion’ or ‘Burning’ is an exothermic chemical reaction between a fuel and an oxidant with a production of heat. CH4 + 2O2CO2 + 2H2O + energy approx. 1 gal of water per 100,000 btu/hr ‘fired equipment specialists’

  22. 3 Tsof Combustion: • - Time • - Turbulence • - Temperature • A/F (Fuel Equivalence Ratio) = Φ • Φ = 1 stoichiometric • Φ > 1 lean • Φ < 1 rich ‘fired equipment specialists’

  23. TYPES OF FLAMES PREMIXED – TYPICALLY TURBULENT FLOW (Bunsen burner) ‘fired equipment specialists’

  24. DIFFUSION– NON-PREMIXED or NOZZLE MIXED (TYP. LAMINAR) – (candle) ‘fired equipment specialists’

  25. EMISSIONS What is NOx (oxides of nitrogen)? NO – nitrogen monoxide (nitric oxide) NO2 – nitrogen dioxide N2O – nitrous oxide (laughing gas) Cause of major pollution Acid rain Smog (photochemical smog) Ozone depletion ‘fired equipment specialists’

  26. NOx Formation Mechanisms Thermal NOx High temperature reaction between nitrogen and oxygen >2000oF Zeldovich mechanism (1947) N2 + O2 NO, NO2 Prompt NOx Fast reaction between nitrogen, oxygen and hydrocarbon radicals CH4 + O2 + N2 NO, NO2, CO2, H2O, trace species Fuel NOx Direct oxidation of organo-nitrogen compounds in fuel RxN+ O2NO, NO2, CO2, H2O, trace species ‘fired equipment specialists’

  27. NOx Formation Mechanisms ‘fired equipment specialists’

  28. NOx REDUCTION TECHNOLOGIES Pre-combustion FGR (Flue Gas Recirculation)– PowerFlame Fuel/Air staging– John Zink, Callidus, Zeeco Air Premix technology - MaxonKinedizer Metal Fiber burner - Parker ‘fired equipment specialists’

  29. NOx REDUCTION TECHNOLOGIES Post-combustion Allows NOx to form and then breaks it down in the exhaust gases using catalytic reduction – typically used on larger utility-size equipment ‘fired equipment specialists’

  30. Burners What is a function of a burner ? Fuel and air metering Proper mixing Flame shaping Emissions control CCME guidelines for NOx formation < 49 ppm OVER 10MM BTUs/hr input (currently). Some zones in Alberta require lower concentrations. ‘fired equipment specialists’

  31. Premixed burners ‘fired equipment specialists’

  32. Metal Fiber BurnersPremixed surface burn technology ‘fired equipment specialists’

  33. PowerFlame burner Flue Gas Recirculation Low NOx with FGR - 8:1 turndown ‘fired equipment specialists’

  34. MaxonKinedizer Nozzle mixing medium velocity Low NOx - 12:1 turndown ‘fired equipment specialists’

  35. Efficiency What is efficiency and how do you measure it? A)Combustion efficiency Chemistry of the fuel Net temperature of the exhaust gas % O2, CO2 or CO after combustion ‘fired equipment specialists’

  36. COMBUSTION EFFICIENCY CALCULATION OF HOW WELL EQUIPMENT IS BURNING A SPECIFIC FUEL. ‘HEATING VALUE’ – ENERGY AVAILABLE PER UNIT MASS OR VOLUME (kJ/m3, Btu/lb, Btu/ft3)FOR A GIVEN FUEL (TYPICALLY DOES NOT INCLUDE CONDENSATION OF WATER VAPOURS). LHV – LOWER HEATING VALUE – NET HEATING VALUE HHV – HIGHER HEATING VALUE – GROSS HEATING VALUE ‘fired equipment specialists’

  37. Efficiency B) Heater/Boiler efficiency Gross Heat Input minus Heat Output Stack losses Moisture Wall loss ‘fired equipment specialists’

  38. Equipment Efficiency ‘fired equipment specialists’

  39. Equipment Efficiency Typical equipment efficiency is around 80 % based on LHV – typ. 60-65% radiant , 10-30% convective How do you increase efficiency Condensing Economizers recover latent heat of water vapour (Condensing Boilers) Sensible heat from flue gas (WHRUs) Efficiency increase up to 96%+ ‘fired equipment specialists’

  40. Economizer ‘fired equipment specialists’

  41. Equipment Efficiency • Direct fired heater vs Indirect fired heater • Direct fired – where energy is transferred directly to the process fluid flowing in the coils installed in the furnace. ($$$) ‘fired equipment specialists’

  42. Equipment Efficiency • Indirect fired – where energy is first transferred to a fluid or solid which then serves as the heating medium. ($) BATH HEATER ‘fired equipment specialists’

  43. ABSA ASME Section I – steam > 15 psi - water > 160psi or temp > 250 oF ASME Section IV – steam < 15 psi - water < 160 psi and temp < 250 oF ASME Section VIII - WHRU ‘fired equipment specialists’
