A fourth replacement boiler feed strainer was supplied for a large UK coal-fired power station.

The Eliminator design of strainer incorporates a wedgewire screen that is extremely robust and overcomes many of the problems of the previous wire wound strainers. These screens were liable to be damaged easily resulting in the wire stripping off and potentially damaging the feed pump.

The new units are also fitted with a mechanical seal overcoming the problems of gland leakage which plagued the previous units.

Design conditions

  • Design flow: 1,620 m³/ hour
  • Design temperature: 140ºC
  • Design pressure: 11 BarG
  • Operating pressure: 6 Bar G
  • Screen opening: 200 micron

The units are operating with excellent results.
