Not Too Hot To Handle!

Working in collaboration, creating tailored solutions, engineering to improve efficiency.

Industry: Power & Energy

The Application:

  • A regular client based in Europe was constructing a new facility to process ash from an incinerator.
  • The ash would be discharged at around 450°C
  • An airlock was required to prevent air loss through the system which can lead to difficulties processing the ash

The requirement:

  • A valve that would be capable of handling an abrasive product at elevated temperatures whilst maintaining an effective airlock

The solution:

  • Our range of rotary valves are built to withstand high operating temperature and abrasive products
  • A 300mm valve was chosen and fitted with high temperature bearings, packing and protective heat-shields for the gear-motor drive
  • Our own Rotospeed speed monitoring unit was installed on an extended mounting to monitor the valve speed and to alert the operator should the valve speed fall below a pre-set level
  • Abrasive resistant steel rotor tips were installed to cope with the abrasive product

The result:

  • The valve has been working perfectly since it was installed, with the elevated temperatures not an issue

Latest Case Studies

Converting Waste Plastics from the Ocean

An innovative customer has developed a revolutionary system for converting waste plastics, including ocean borne material into a syngas containing hydrogen. This syngas can then be used as a source of electricity or heat.

Innovative elongated Rotary Valve

Accurate feeding and filling of sachets, reduced segregation and a greater consistency in the particle distribution, which gave less variation in taste of the reconstituted beverage.
