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’
3 Ts of Combustion: • - Time • - Turbulence • - Temperature • A/F (Fuel Equivalence Ratio) = Φ • Φ = 1 stoichiometric • Φ < 1 lean • Φ > 1 rich ‘fired equipment specialists’
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’
TYPES OF FLAMES PREMIXED – TYPICALLY TURBULENT FLOW (Bunsen burner) ‘fired equipment specialists’
DIFFUSSION– NON-PREMIXED (TYP. LAMINAR) – (candle) ‘fired equipment specialists’
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’
NOx Formation Mechanisms Thermal NOx High temperature reaction between nitrogen and oxygen >2800oF Prompt NOx Fast reaction between nitrogen, oxygen and hydrocarbon radicals Fuel NOx Direct oxidation of organo-nitrogen compounds in fuel ‘fired equipment specialists’
NOx REDUCTION TECHNOLOGIES FGR (Flue Gas Recirculation)– PowerFlame Fuel/Air staging– John Zink, Callidus, Zeeco Air Premix technology - MaxonKinedizer Metal Fiber burner - Parker ‘fired equipment specialists’

MaxonKinedizer Nozzle mixing medium velocity Low NOx - 12:1 turndown ‘fired equipment specialists’
Equipment Efficiency What is efficiency and how do you measure it? Combustion efficiency Chemistry of the fuel Net temperature of the exhaust gas % O2, CO2 or CO after combustion Heater/Boiler efficiency Gross Heat Input minus Heat Output Stack loses Moisture Wall loss ‘fired equipment specialists’
Equipment Efficiency ‘fired equipment specialists’
Equipment Efficiency Typical equipment efficiency is around 80 % based on LHV – typ. 60-65% radiant , 10-20% 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’
Economizer ‘fired equipment specialists’
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’
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’
