Pipe Bundles for Wet Electrostatic Filters in the Power Generation Industry

When it comes to power generation from coal-fired power stations, STEULER-KCH can also deliver the ideal solution. The wet electrostatic filters found in the flue gas desulphurisation units of coal-fired power stations serve to remove particulate pollutants, such as aerosols, dust and ash. STEULER-KCH supplies the custom-made pipe bundles for these wet electrostatic filters. We use special precipitation pipes that are proportioned to  accommodate the volume of gas being generated and that have a larger diameter than that customarily used for chemical processes.

In order to separate out the pollutants, they are first electrostatically charged within the pipes of electrostatic precipitators, then deposited on the oppositely charged surface of the pipes, and finally collected in the filter sump. Electrically charged plastic precipitation bundles are primarily used where conventional materials fail due to insufficient resistance.

STEULER-KCH's portfolio of services includes the design, production and installation of pipe bundles made from thermoplastic polymers, both with and without electrically conductive surfaces. We use modular designs that allow us to adapt the bundles to different component shapes and sizes, according to customer specifications. Our many years of experience make us the partner of choice for glass-fibre reinforced plastic (GRP) housings and pipes for irrigation systems and gas distribution.

We primarily use the following thermoplastic materials for our pipes:

  • Polypropylene (PP), adapted to be flame retardant
  • Unplasticised polyvinyl chloride (PVC-U), inherently flame retardant
  • Post-chlorinated polyvinyl chloride (PVC-C), inherently flame retardant
  • Polyvinylidene fluoride (PVDF), inherently flame retardant

We offer you professional support from an assigned contact person – from the initial consultation through to on-site installation. We provide you with detailed, customised advice on selecting the combination of materials best suited for your project, taking into account factors from the plant environment, such as the expected chemical, mechanical and thermal stresses and the plant’s geometry. Our consultancy service always includes a plausibility check regarding design and materials and comprehensive project support to ensure smooth and timely implementation – even for complex projects. We develop custom combinations of materials in close consultation with users from the field. Our after-sales service gives our customers the opportunity to share their experiences of completed projects, to learn about current product developments and if desired, to have previously installed products inspected and evaluated concerning their remaining service life.
