Zaunergroup receives Gold Safety Award

It’s time for Safety: At Zaunergroup our main goal is to create permanent values and to protect our employees and the environment. We are very proud for receiving the GOLD SAFETY AWARD from Construct Secure. We reached a total score of 89.94 out of 100.

“Zauner Anlagentechnik GmbH has done a remarkable job of implementing a strong safety management system. In addition to keeping employees safe, safety performance of this caliber should reduce their insurance premiums,” says Garrett Burke, CEO of ConstructSecure.“

The Safety Assessment Programm reviews a company’s historic safety performance and current safety management systems. The platform normalizes data for vendor or contractor size and type of work performed.

The program provides thorough, objective and consistent evaluation of company performance so clients can identify, monitor and manage risk smarter. The results provide a strong indicator of how a vendor or contractor values safety and a reliable predictor of future performance.

Zaunergroup would like to thank all persons involved for their excellent work!

Our vacuum condensation unit is on its way to Holland!

Together with our partner ABH Thermo we are glad to send a vacuum condensation station to Holland again. The application in a municipal district heating system with turbine power generation contributes significantly to the plant optimization.

Technical data
The plant has a capacity of approx. 18 MW and is designed for condensing the exhaust steam from the steam turbine at a maximum rate of 24.4 t/h. The vacuum condensation station is located in a biomass power plant directly under the turbine table and under the turbine. The biofuels are fed to a combustion furnace, the waste heat from this to a steam boiler for steam generation. This live steam is sent to a single or multi-stage steam turbine where it is converted into electricity. In the process, the steam pressure is reduced from stage to stage of the turbine, right down to the vacuum range. Since the turbine must be protected from condensate water, our station is located below the last stage of the turbine and acts as a final condenser. This means that the vacuum steam is fed into our condenser and condensed via the tube bundle.

During the condensation process, the steam energy is transferred to the district heating water in the pipes and heats it, for example, from 70° to 90°. This district heating water is fed into a municipal district heating network for heating purposes. Furthermore, our level measurement and control system ensures that the condensate level in the apparatus always remains constantly below the bundle. The evacuation system, which is also installed, extracts non-condensable gases (air), as these would cover the heat exchange surfaces and reduce the capacity of the unit. The condensate produced from the condenser is returned to the feed water tank via frequency converter-controlled pumps, the level control and the 3-way distribution valve and from there to the steam boiler. From there the process starts again from the beginning.

AGRANA opens second wheat starch plant at Pischelsdorf (NÖ)

The fruit, starch and sugar group AGRANA has built a second wheat starch plant at the site of its biorefinery in Pischelsdorf in the Tullnerfeld region & Zaunergroup was among those involved. We were contracted for the decanter station as well as the equipment assembly of the starch factory and the decanter station. Furthermore, we also completed the piping for the starch and gluten drying. 5 km of pipes, 7000 fittings, 25 tons of secondary steel construction, … was installed in over 64,000 hours of work. The project was completed safe, on time and without any incidents. The start of construction was in March 2018, the plant was completed in December 2019.

More information about the new plant can be found here:

Half time in Prague

The operator of the Prague municipal waste incineration plant, Prazske sluzby a.s. has ordered the ZAUNERGROUP for the engineering, the supply, the dismantling/erection and commissioning for the “revamping” of the flue gas cleaning systems of the 4-line municipal waste incineration plant. Hereby, all 4 existing flue gas cleaning systems of the municipal waste incineration plant will be adapted to the new incineration technologies and boiler conditions over the next 4 years. The reconstruction will increase the availability with this new facilities and thus restore the safety for the waste incineration of the city of Prague and its surroundings.

Smurfit Kappa Nettingsdorf invests & Zauner is part of it

Smurfit Kappa Nettingsdorf is investing €134 million at its Nettingsdorf site to renew the energy supply as part of the Future Energy Plant project. The core of the project is a new soda boiler and a new steam turbine. Zauner Anlagentechnik GmbH is part of this project with the section “Balance of Plants”. This part includes the connection of the new plant with the existing one, as well as a new condensate system and the piping of the turbine hall. Zauner provides the know-how in design and planning as well as the competence in assembly and the global control concept.

A milestone was the lifting of the 105 t B2 pipe bridge, which was lifted in two parts on 20.11.2019. A truck-mounted crane with a load capacity of 500t was used for this purpose. The upcoming work includes the completion of the condensate system and the lifting of the remaining three pipe bridges in January. Also in January, the assembly work will start in the turbine hall, which represents the largest part of the BOP construction phase. The new plant will start up in summer 2020, replacing the old soda boiler and steam turbine.
