  • Method and means for distributing gas along an extended inlet portion of gas treatment means
    Patent number: 4213766
    Abstract: A gas conduit delivers gas to an electro-precipitator at an angle to the direction of gas flow through the precipitator. Projections are provided in the conduit adjacent the inlet to the precipitator to increase the thickness of the turbulent zone of the gas boundary layer; this urges gas towards upstream regions of the inlet of the precipitator, and thereby enhances even distribution of the gas across the inlet.
