Projekt

  • Gas-fired power plant

  • Operator: DEW21

Factory
Heating
Pressure maintenance

Performance parameters

  • Temperature: 120 / 70 °C

  • Safety Temperature Limiter: 130 °C

  • p0: 5–7.5 bar

  • Max. pump delivery pressure: 7.5 bar

  • Safety valve: 16 bar

Task

  • Due to space constraints, the hydraulic module (Reflex GH 100-S-F GY) was built inna separate configuration. The overflow section was therefore mounted upright on a mounting wall.

  • The vessels were to be mounted on bolts already set in concrete (axial play of the holes ± 2 mm). For this purpose, each vessel was measured and the measurement reports were sent to the construction site.

Product solution

  • 2 × Reflex GG primary vessel 27,000 l, 6 bar, 1 × BOB pipe each

  • 6 × Reflex GF secondary vessel 27,000 l, 6 bar, Duo water connection

  • 1 × Reflex G control vessel 2,000 l, 16/3.5 bar

  • 1 × Reflex GH 100-S-F, 100-S-F GY

  • 3 × pumps

  • 1 × S7 control cabinet

Achieved goals

  • An old coal-fired power plant was replaced with a new gas-fired power plant, which meant that the new construction also required new pressurisation.

  • Reflex implemented an additional pressure maintenance system in order to guarantee 100 per cent supply security for end customers by combining several networks in the city of Dortmund.
