Pure Steam Generator
A thermosyphon pure-steam generator that evaporates treated feed water and separates entrained droplets before delivering steam to pharmaceutical sterilization duties.
- Thermosyphon evaporation
- Low-velocity droplet separation
- Automated pressure and level control
Product Introduction
The Pure Steam Generator uses plant steam or an electric heater to boil treated feed water in a hygienic heat exchanger. Natural circulation carries the two-phase flow into a tall evaporator/decontamination column, where low vapor velocity and vertical separation limit liquid carryover before pure steam leaves the top outlet. Feed-water level and product-steam pressure are regulated as demand changes.
Key Features
Parallel thermosyphon bodies
Vertical decontamination column
Natural-circulation evaporation
Feed-water level transmitter
Pure-steam pressure control
Automatic blowdown interface
Integrated HMI and utility monitoring
Customer Product Concerns
Pure-steam production must respond to variable demand while controlling feed-water level, droplet entrainment and non-condensable gases across startup and steady operation.
Rapid demand changes disturb generator pressureModulate primary heat input from product-steam pressure and retain useful steam volume in the evaporator.
Feed-water droplets carry into the steam outletUse a tall low-velocity decontamination column and controlled thermosyphon circulation.
Unstable level exposes the heating surfaceRegulate feed-water admission continuously from the evaporator level transmitter.
Startup gases enter the clean-steam headerProvide controlled venting and warm-up logic before releasing steam to the distribution system.
Typical Applications
Sterilize-in-Place systemsAutoclave steam supplyAseptic process-equipment sterilizationSterile barrier steamQualified clean-utility humidification
