Water for high pressure boilers with steam turbine

Reference ID: 119289
Industry: Heat and power plants
Application: Boiler water

EC Gliwice is the strategic, local supplier of district heating for industrial and public buildings with a generation capacity of 67 MWt.

SFW Energia needed to expand the power generation module. Installation of the steam turbine introduced the need to use water in accordance with the standards PN-EN 12952-10 and PN-EN 12952-12.

The water treatment plant is designed and built to supply boiler feed water for high-pressure boilers as well as make-up water for the district heating network.

SILHORKO-EUROWATER has supplied project and main components for the construction of the complete water treatment plant as well as start up and final documentation

Raw water comes from municipal waterworks and is undergoing the following treatment steps: 1) Sand filtration 2) Softening 3) Double pass membrane filtration (DPRO) with NaOH dosing between RO passes 4) Electrodeionization-polishing (EDI).

Parallel to the EDI module is a fine polishing mixed bed installed as a security module.
