The combined heat and power plant produces electricity and heat energy in joint production. Make-up water for both a high-pressure steam boiler and for distribution of the district heating are needed.
The make-up water for the high-pressure steam boiler is demineralised according to the patented water treatment principle of UPCORE, combining all the known advantages of water demineralisation through ion exchange with the counter-flow principle. After the UPCORE unit, the water is polished in a mixed bed unit, leaving the demineralised water with a final conductivity of under 0.07 μS/cm and a silica content of less that 0.01 mg/litre. The water treatment plant comprising two lines connected in parallel. Each line is dimensioned for a flow rate of 5 m3/h.
The make-up water for the distribution network of the district heating is produced in a RO-PLUS unit. RO-PLUS units are designed for a recovery rate up to 90%, compromising neither the reliability nor the water quality. As pre-treatment of the feed-water to the reverse osmosis unit a softening unit is used. This water treatment plant has a flow rate of 15 m3/h and the conductivity of the demineralized water will be under 10 μS/cm.
Furthermore, the PLC control are integrated into the existing SCADA system of the heat and power plant.
