Furnace Ozonator

  1. 1. Ozonators where used mainly in mid range to large boiling houses and heat factories.Furnace Ozonator Is it worth of effort?
  2. 2. Typical minuses of home furnaces:Air intake is taken from room and moves heat awayPoor Fireplace construction limit max temp < 650 C;Water heater cannot be disassembled for maintenaceExhaust releases hot gass to chimney
  3. 3. 30 x 30 x 15 cm pack would cost about 350 Eur together with HV electronics
  4. 4. and produce following particles
  5. 5. The First root of Evil
  6. 6. Furnace ozonator would removePullutant EffectVOCs - Volatible Organic Compounds YES ~ 50%Mono carbon oxide CO. YES ~80%Dioxide carbon CO2. NOHydrocarbons CxHy. NOSulpher oxide SO2. NO ~20% with steam moisturizer*First nitric oxide NO. YES ~90%Second nitric oxide NO2. YES ~80% with steam moisturizer* *Feed in chimney
  7. 7. How much ozone we need?
  8. 8. Ozone impact on VOC conversion
  9. 9. Danish Gass authors where found that• The reduction of NOx emission is more efficient at lower temperature (110 °C) than at higher temperature (160 °C), so ~5% (1/20) of ozone produced must be feed directly to chimney via second flow regulator;• O2 is more efficient than air as ozone agent (keep oxigen cilinder).• The technique is applicable on flue gas from biomass combustion despite the presence of compounds such as SO2 and HCl .• Reduction of NOx emissions requires approximately half as much O3 when it is applied to the natural gas fired engine unit compared to the straw fired boiler unit.• The higher O3 consumption on straw fired units is due to both higher flue gas temperature and larger NOx fluctuations in the flue gas compared to the gas engine unit.
