At the end of 2017, we began conducting research to increase the efficiency of current types of steam coolers in connection with the more tight requirements for reducing temperature of reduced sealing steam, especially by turbine manufacturers. In this project, we investigated the effect of condensate temperature, which serves to cool the sealing steam, and the output of this was the ring design of steam coolers that was implemented into the company’s production program. The research activity was carried out with the support of the European Regional Development Fund, from the Operational Program Enterprise and Innovation for Competitiveness (project registration number: CZ.01.1.02/0.0/0.0/16_045/0010777 – Steam Cooling Research).
Following this successful research project, we decided to continue the development of steam coolers in 2018, this time we focused on the new design of steam cooler using atomizing steam. Due to this there is a better mixing of the cooling medium and the cooled steam. This new type of steam cooler was first repeatedly tested in our testing laboratory by simulating real conditions, and in 2019, its deliveries to our customers started. This project was also co-financed by the European Regional Development Fund, Operational Program Enterprise and Innovation for Competitiveness, under the registration number CZ.01.1.02/0.0/0.0/17_205/0013266 – Steam Cooling with Atomizing Steam).
The new design allows perfect mixing of the coolant with cooled steam even with a small flow. Thanks to this effect, the length of the section to the temperature sensor is shortened and no condensate appears behind the steam cooler.
For the end customer, this steam cooler with the VA7040 designation brings several clear advantages, namely:
- perfect mixing of refrigerant and cooled steam,
- there is no residual condensate in the cooled steam,
- shorter length necessary for steam cooling,
- reduced temperature to which the steam can be cooled,
- achieving precise parameters of the cooled medium,
- favourable price.
