The ProSonixTM I-Series Direct Steam Injection heater’s unique method of direct steam injection utilises internal steam modulation via an integral pneumatic actuator to accurately deliver the appropriate mass flow of steam for the required heating. This modulating 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 opening. By establishing choked flow, the steam mass flow is 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.
Features & Benefits
- 3-Dimensional steam injector delivers up, down and side to side steam injection pattern to optimise steam mixing and rapid condensation
- Angled diffuser reduces flow disruptions and suitable for fibrous slurries
- Single point steam injector diffuser connection allows for complete fluid pass through clearance with no build-up points for fibrous materials
- Eliminates plugging and fouling from burn and scorch sensitive slurries and sludge’s
- Internally modulated steam injection controls mass flow of steam allowing for smooth and stable operation
- Energy savings as a result of low pressure drop across the PSX DSI heater
- Positional steam inlet allows steam inlet flange to be rotated in 360° for ease of steam piping connection
- Secondary internal steam shut-off (optional) for integral steam shut-off
