More Information
Summary:The invention discloses a desuperheater and spray nozzles therefore. According to the invention, a steam assisted ring style desuperheater includes a ring body defining an axial flow path and one or more spray nozzles extending through a wall of the ring body. Each of the nozzles is connected to a separate cooling water manifold and atomizing steam manifold to conduct cooling water and atomizing steam separate from each other through the spray nozzle to an injection point. An atomizing head of each nozzle combines the cooling water and atomizing steam to form a spraywater cloud that is injected radially into the axial flow path. The spray nozzles include one or more flow passage inserts that define separate first and second fluid flow paths for conducting the cooling water and the atomizing steam separately through the spray nozzle.
