Steam Injection Heater with Internally modulated Steam Flow Control Design
ProSonix’ unique method of direct steam injection heating utilizes internally modulated steam control to precisely deliver the appropriate mass flow of steam for the required heating. This design offers a precise method of steam control through a choked flow control delivery of the steam. Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered nozzle. By establishing choked flow, the steam mass flow can be metered to precisely control the heating of the liquid. This produces predictable results based on position of the stem plug. Through a variable-area steam diffuser, steam flow is metered at the point where steam and liquid first contact and mix. This method eliminates the need for an external steam control valve or downstream mechanical mixing devices.
