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.
As part of our service we conduct tests on individual plants to determine the optimum operating regime in order to minimise ESP power consumption and SO3 injection rates, and containing emissions levels below the statutory target limit. Howden’s installations are proven to offer optimum performance in high ambient temperature environments, on coal with high ash content.
