Reference: GKM Unit 9

Steam Power Plant

Characteristic Data:

Power output: 911 MWel
Max. district heat generation: 500 MWth
Rated thermal input: 1,812 MW
Electrical efficiency: 46,4%
Fuel: Bituminous coal

Steam parameters:

  • Live steam pressure: 290 bar
  • Live steam temperature: 600 °C
  • Live steam mass flow: 663 kg/s

Type of cooling:

  • Discharge cooling with 10 wet-cell-type units

Trial run:

  • September / October 2014

Description of site:

Mannheim-Neckarau, directly on the Rhine, Germany

Site characteristic:

  • Power plant site directly on the Rhine, the area of which is very confined
  • Because of soil conditions of the Rhine plain the buildings  had to be designed with pilings to prevent too much settling

Particularities/constraints:

Direct proximity to an urban area with strict regulatory requirements for environmental protection has been stipulated for:

  • emissions / air quality control
  • noise emissions
  • dust formation
  • fish protection
  • water pollution control

Project description:

  • The steam turbines are designed as a five-casing series with six-pass exhaust, and have bleeds for the heating of district heating water via the preheater line especially conceived for it.
  • Flue gas is cleaned as follows:
  • Catalytic denitrification (SCR) with ammonia water
  • Dust separation in the electrostatic precipitator
  • Flue gas desulfurization unit (FGD) limestone gypsum
  • Wet scrubbing
  • Electric power is fed into the supply network via the existing  220 kV switchgear building

Scope of services:
