Slightly superheated or saturated steam is often utilized for industrial production processes. The best examples of this can be found in the following industries:
Single-stage steam ejector vacuum systems are capable of handling both condensable and non-condensable vapors and gasses. They are also suitable for non-sensitive applications where small amounts of liquids or solids do not result in operating issues.
The Jetomat® Baelz 590 is a controllable steam ejector with cooling water injection. Also known as a desuperheater, this system can lower the temperature of dry, superheated steam (exceeding 212 °F) as it enters the device by injecting a certain quantity of water into the steam flow. The resulting saturated steam assists with industrial heat transfer applications in refineries, chemical plants, and other facilities.
The condensation enters the system slightly downstream from the Venturi throat, sprayed at a minimum pressure of 5 to 10 psi into the vapor flow above the steam line pressure. This results in a relative velocity between the steam and condensate that produces the smallest possible droplet size. The superheated steam can be effectively reduced to 5-10 °F above saturation.
Desuperheaters offer the following benefits:
- Help maintain and control steam temperatures
- Improve operations and product quality
- Lower costs by saving and reusing heat
- Prevent downstream equipment damage
- Reduce the need for costly heat-resistant alloys in process equipment
- Prolong equipment service life
