Used complete KALINA system plant

Listing description

The Kalina plant was assembled and completed by 2016 as a facility to generate electricity and provide heat from geothermal energy. From 2016 to 2018, the commissioning of the power generation plant took place. After commissioning, the Kalina plant could only be operated at partial load. Later, technical problems arose, particularly with the turbine. Operation was discontinued and the geothermal wells were used to supply heat.

- Power Island Coriolis measurements - Siemens Sitrans
Year of manufacture: 2015
Quantity: 2 pcs.
Functional: Yes
Short description:
The Siemens SITRANS FC410 Coriolis mass flowmeters are used to measure the flow of the ammonia-water mixture. The measurements are located upstream of the LT recuperator and downstream of the spray pump. Coriolis flowmeters measure the actual mass flow with a higher accuracy than comparable thermal mass flow measurements. The Coriolis measurement behind the LT recuperator is designed in DN 100 and for a pressure of 50.1 bar. The Coriolis measurement behind the spray pump is in DN 50 and designed for a pressure of 12.7 bar. The housing is made of stainless steel AlSI 304.

- Recooling plant Hybrid cooling towers - Jaeggi Hydraulic Technology
Year of manufacture: 2014
Quantity: 7 pcs.
Functional: Yes
Short description:
The hybrid cooling towers of Jaeggi Hybridtechnologie are 3-flow cross/counterflow air coolers and serve to cool the cooling medium and to remove excess waste heat by means of ambient air (dry cooling). At higher ambient temperatures, the surface of the fin heat exchangers is additionally wetted with water to improve cooling. The cooled coolant is then returned to the cooling circuit. The cooling capacity is 3,000 kW / cooling water flow 276 m³/h.
The dimensions are (LxWxH) 12.788x3.076x4.901 m.

- Recooling plant Pressure maintenance system cooling water - Aqotec
Year of manufacture: 2015
Quantity: 3 pcs.
Functional: Yes
Short description:
The system pressure is kept constant in the cooling circuit by means of the pressure maintenance system. The expansion system consists of 3 buffer tanks that are pressurised with nitrogen and have an expansion volume of around 4.5 m3.
(3x1.5 m3). The buffer tanks are designed for an operating temperature of 75 C and an operating pressure of 0.5 bar. The tanks are 2.30 m high and have a diameter of 1.20 m.
If the pressure in the cooling water system drops, it is fed into the system by means of two CRIE5-5 pumps from Grundfos. In order to keep the pressure difference between the mains pressure and the feed pressure constant, the pumps are speed-controlled.
