A method of and apparatus for chemically conditioning a particle-laden gas stream to improve the collection characteristics of the entrained particles comprising the injection of a conditioner solution, preferably ammonium sulfate ((NH4)2 SO4), into the gas stream before the stream enters an electrostatic precipitator. The apparatus for injecting the solution includes an injection nozzle, inserted in a gas duct going to the precipitator, connected to a supply of the solution with a power supply and metering means for controlling the amount of solution injected in proportion to the amount of gas being conditioned. |
