A method for reducing spark rate and / or increasing voltage on a cold side electrostatic precipitator through which a particulate-containing gas flow is directed.

摘要

A method for reducing spark rate and / or increasing voltage on a cold side electrostatic precipitator through which a particulate-containing gas flow is directed. This invention provides methods for reducing a spark rate and / or increasing voltage in a cold side electrostatic precipitator through which a particulate-containing gas flow is directed, wherein said electrostatic precipitator has a spark rate and a voltage. The method comprises injecting an amount of a halogenated carbonaceous substrate formed of a carbonaceous substrate and an elemental halogen and / or a hydroalic acid into the particulate containing gas stream upstream of the electrostatic precipitator, so that the spark rate decreases by about 40 ° C. % or more and / or so that the stress can be increased by about 20% or more than when said halogenated carbonaceous substrate is not injected.
