With the commissioning of the steam turbine 9, the efficiency of energy production in paper and board mill Varel has been further increased. The steam turbine 9 has an output of 13.9 MW and the steam turbine power generation takes over the 1 and 2 These were taken from the regular operations, but are still available as reserve capacity.
The steam is at 480 ° C and 80 bar led to the turbine and exits at 170 ° C and 6 bar. Compared with the previous steam turbine, the efficiency could be increased by 25%, which contributes to a significant reduction in specific CO2 emissions.
The turbine itself weighs 25 tons, to the generator comes with 45t. Together with the gear and the other units, the total system weighs about 100 tons. The integration of such a complex system into an existing combined heat and power plant is also a major logistical challenge, the team the power plant the paper and cardboard factory Varel and those involved in the installation companies have passed with flying colors.
The continued investment in environmentally friendly and future-oriented energy shows once more that the protection of the environment for the paper and cardboard factory Varel has a great importance.
