Method for reducing a Spark Frequency and / or increase the Voltage in an Electrostatic precipitator, which comprises injecting an amount of substrate in the Halogenated Carbonaceous Particulate containing gas Stream upstream of the electrostatic precipitator.
Method for reducing a Spark Frequency and / or increase the Voltage in an Electrostatic precipitator, which comprises injecting an amount of substrate in the Halogenated Carbonaceous Particulate containing gas Stream upstream of the electrostatic precipitator.
This invention provides methods for reducing a spark rate and/or increasing the voltage in a cold-side electrostatic precipitator through which a particulate-containing gas stream is directed, wherein said electrostatic precipitator has a spark rate and a voltage. The methods comprise injecting an amount of a halogenated carbonaceous substrate formed from a carbonaceous substrate and an elemental halogen and/or a hydrohalic acid into the particulate-containing gas stream upstream of the electrostatic precipitator, such that the spark rate decreases by about 40% or more and/or such that the voltage can be increased by about 20% or more than when said halogenated carbonaceous substrate is not injected.
