Abstract: An adjustable conical atomizer comprises a body part having an end or discharge face with a conical recess and a conical plug having a complementarily conically-formed surface which is adjustably positioned in the conical recess. The size of the cavity formed between the plug and the body is varied by changing the relative positions of the plug and the body, for example, by using an indexing bolt which connects the body part and the plug parts. The body or a connection to the body is provided with channels or passages for the passage of two or more fluid streams into the space between the plug and the body part for intimate mixing therein. The fluid stream includes a liquid which is accelerated in this zone between the body and the plug. The plug and the body form an annular discharge therebetween which diverges in an outward direction.

Abstract: An improved method for removing sulfur oxides from a hot gas by introducing the gas into a first compartment of a spray drying reactor chamber for settleable particulate removal, by then directing the gas to a second compartment of the reactor chamber wherein the gas is contacted with an atomized alkali slurry for sulfur oxide removal by formation of a dry mixture of sulfite and sulfate compounds, by removing a portion of the dry mixture from the gas in the second compartment and by passing the gas from the second compartment to a dry particle collection zone for removal of substantially all of the remaining gas entrained dry mixture.
