Flue Gas Conditioning

 

Howden optimises the performance of existing furnace electrostatic precipitators (ESPs) by injecting controlled doses of Sulphur Trioxide (SO3), to improve collection rates.

SO3 has a significant positive effect on the performance of ESP plant. We have been very successful in improving collection rates of existing electrostatic precipitators used on furnaces & power utility boilers.

Flue Conditioning

Key Features

  • ​​The SO3 flue gas conditioning system supplied by Howden uses a liquid Sulphur Dioxide (SO2) to Sulphur trioxide (SO3) gas generator to provide the optimum in coal-burning power plant fly ash conditioning. The SO3 flue gas conditioning process vapourises SO2 in air to produce an SO3 gas stream for injection into flue gas ducts upstream of the electrostatic precipitators.
