ENSAT allows heating, mixing and pumping liquids with no electrical power supply. It provides a substantial reduction in energy resource consumption, a significant decrease in both capital expenditure and maintenance costs, and a positive environmental impact, effectively eliminating greenhouse emissions from inefficient heat exchange systems. ENSAT works by exploiting three natural phenomena: - The speed of sound (Mach 1) is different in different media (i.e. steam and water)
- Mach 1 is much lower in the mixed media than in either of the media constituting the mix
- Mixing these media creates a "quantum cocktail", producing a pressure jump in the mix as it crosses the dramatically lowered Mach 1 threshold, and resulting in additional thrust in the outlet flow.
And because TJF units are engineered to capture and use all the enthalpy in a multi-phase system — and precisely control outlet temperature and pressure — our systems can deliver outlet pressures higher than the combined inlet pressures, regardless of lower steam pressure. What's more, the integration of ENSAT into condenser, desalination and deaerator applications eliminates steam traps, runoff and cooldown operations. This unique versatility and ability to capture and utilize all of the enthalpy wasted in conventional systems adds a lot to your fuel and energy savings, and further reduces environmental impact.  |
Basic TJF Device Scheme
The device is a metallic T-fitting with flange or clutch coupling with external tubes. Water and steam are supplied to the device separately. When mixed they form a homogeneous two-phase steam and water mixture. The local speed of sound within such a mixture is rather small (5-10 m/s). Therefore the speed of steam and water mixture at the device mixing chamber inlet is equal or larger than that of local sound. When the supersonic mixture is decelerated at the outlet of the mixing chamber there is a rapid pressure increase, the stemperature grows, and as the steam phase is condensed. As a result, the outlet mixture pressure is much higher than the inlet water and steam pressures. Because of developed surface of heat exchange in the mixing chamber due to foggy or foamy structure of the steam-water mixture, dimensions of the device are smaller compared to all heat exchangers of surface type, plate heat exchangers included. The basic unit designs can function within the following parameters on input: Steam pressure: from 0 to 70 àtm
Water pressure: from 0 to 70 àtm
Water temperature: from 0 to 150°C
Amount of steam consumed: 0-14% of water consumption Heads-up Note to Engineers TJF units are not steam-injector devices. A brief technical whitepaper on ENSAT will be available for download from our site soon. Have a nice day! |
