The Kiekens Venturi is our top of the line Desuperheater, known all over the world as the most reliable Desuperheaters on the market. Therefore, the Kiekens Venturi is frequently used in the oil and gas industry, where the highest safety standards are applicable. The Kiekens Venturi is made in of a solid forging, where excess material is cut away – this means no welding or moving parts. As a result, the Kiekens Venturi is insensitive to thermal shocks and requires virtually no maintenance. With a lifespan of more than 30 years, the Kiekens Venturi is widely regarded as the Desuperheater solution with the lowest cost of ownership.
The lowest cost of ownership solution for desuperheating VHP/HP/MP/LP steam is the Kiekens Venturi Desuperheater.
The key feature of the Kiekens Venturi Desuperheater is that it obtains a stable conditioned desuperheated steam flow temperature handling high amount of cooling water injection in the shortest possible time.
The best solution for Desuperheating VHP/HP/MP/LP steam is the Kiekens Venturi Desuperheater. The Kiekens Venturi Desuperheater is capable of obtaining a stable conditioned desuperheated steam flow to control the temperature and can handle a high amount of cooling water in a very short time span.
The Kiekens Venturi can be installed in-line in your process application. The Desuperheater is custom designed and built to your specifications. Based on your process conditions, we calculate and design the required Venturi orifice diameter, which is key for the Desuperheater to function. The working principle of the Desuperheater is based on the Venturi (vena contracta) principle, which generates dynamical energy inside the Desuperheater, where cooling water is suctioned-in and atomized in fine cooling water droplets by the special wing-shaped spray nozzle design. The combination of the Venturi and the wing-shaped spray nozzle generates high turbulence (vortex) and secures rapid and total evaporation in a very short time period, which are one of the advantages of desuperheater from Kiekens-DSH..
Only a relatively short straight steam pipe length is required for installation, both up- and downstream of the Venturi Desuperheater, and thermal sleeves are not necessary. The steam side turn down ratio (maximum flow/ minimum flow) that can be handled by the Kiekens Venturi Desuperheater depends on the allowable steam side pressure drop across the Desuperheater. As mostly high pressure is available a pressure reducing desuperheating system (PRDS), higher turn down ratio can be achieved.
With no need for maintenance or replacement parts, the Kiekens-DSH Venturi is widely regarded as the Desuperheater with the lowest cost of ownership. Once the Desuperheater is installed, the life cycle costs are incredibly low. So, while the initial investment may be higher, you will easily earn it back in the Venturi’s 30 years lifespan. The low cost of ownership makes this top of the line model the best choice for end users and owners.
The Kiekens Venturi is most commonly used for cooling desuperheated steam. We have installed this Desuperheater model in a variety of industries, like boiler desuperheater or ranging from petrochemicals to pulp and paper processing. Because of its unmatched reliability and resilience, this model has become a staple in the refinery industry or desuperheater in boiler and furnace applications where safety and reliability are a top priority.
Based on your specifications, Kiekens-DSH can perform all necessary calculations described above and supply a complete Venturi desuperheating system.
