The years of operation of the plant translated into the systematic expansion of the Żerań CHP Plant, followed by the replacement of basic generating equipment with new units as environmental aspects became more important. During this period, selected steam boilers were substituted by innovative fluidized bed boilers, while some turbine sets were replaced by modern heating units. In recent years, in view of the need to decommission the existing basic equipment, a number of investments have been made – in particular the construction of a modern gas-steam unit, two peak boiler rooms, operating based on gas-fired water boilers, and the installation of environmental systems on the fluidized bed boilers to guarantee that the operation of the equipment is compliant with stricter emission requirements.
The Żerań Combined Heat and Power Plant with its:
thermal power: 1390 MWt
gross electrical power: 908 MWe,
supplies heat – mains water heating – to 5 district heating areas in Warsaw. The plant is also responsible for the production of process steam for external customers, including PWPW – Polska Wytwórnia Papierów Wartościowych (Polish Security Printing Works).
Primary generating units:
- combined cycle gas turbine unit,
- 2 fluidized bed boilers,
- 2 peak boiler rooms consisting of 5 gas-fired water boilers,
- 5 thermal turbine generators,
- 5 steam boilers (planned decommissioning – boilers with IED derogations).
Several investments have also been made in the past years within the auxiliary systems, which have systematically reduced the impact of the Żerań Combined Heat and Power Plant on the environment. These include:
- construction of a slag settling tank allowing the decommissioning of the combustion waste landfill at ul. Myśliborska with subsequent land reinstatement,
- commissioning of the process wastewater treatment plant.
