Abstract
The present study investigates the characteristics of Moderate or Intense Low-oxygen Dilution (MILD) oxy-combustion in a laboratory-scale furnace. Experiments using natural gas (NG), liquefied petroleum gas (LPG) and ethylene (C2H4) are carried out at a firing rate of 13kW. The furnace temperatures and exhaust emissions are measured for a range of equivalence ratios and external-CO2 dilution rates.It is observed that MILD combustions occur for the three fuels even when using pure oxygen as oxidant. When diluting oxidant by CO2 at a fixed rate, the MILD combustion can be established as long as the equivalence ratio (Φ) is sufficiently high. The region of MILD combustion is found to be wider with dilution by CO2 than by N2. Notably, also, the operating range of MILD combustion is larger for NG than LPG or C2H4 as fuel.Moreover, when Φ
