Abstract
A direct contact steam injection heater that includes a steam diffuser having a plurality of steam diffusion holes that are selectively exposed by a regulating member to control the amount of steam used to heat a liquid. The regulating member is movable within the steam diffuser and includes a seating member to prevent the flow of steam from the diffuser when the regulating member is in a completely closed, seated position. A pair of sealing members surround the discharge region of the steam diffuser when the regulating member is in the closed position. The diameter of the steam diffusion holes and the distance between the steam diffuser and the inner wall of the heater body is selected to maintain a desired ratio to reduce bubbles that cause noise and vibration within the direct contact steam injection heater.
