DTL secure their latest high value order for industrial dampers, working closely with MjØrud AS of Norway.

Damper Technology Ltd (DTL) have recently secured their latest £1m order, for the supply of specialist guillotine and multilouvre dampers for a major gas processing plant in Norway.  The dampers are to be located on the turbine exhaust systems, ahead of the waste heat boilers to allow man-safe boiler access during turbine operation.

 

DTL’s scope covers design, manufacture, shipment and site services by our in-house field engineers, comprising assembly and installation supervision and commissioning activities.  Delivery will be in two phases commencing late 2016 and is due to conclude  in early 2018.  Upon completion DTL will have supplied the additional/replacement waste heat boiler dampers for all 5 power generation trains on the same site.  A key feature of these dampers will be the 321 stainless steel construction, due to the coastal location.

 

The guillotine dampers feature a twin insulated blade arrangement, common screwjack drive, interspace seal air and atmospheric bleed.  Thermodynamic calculations ensure the sealing air pressure and flowrate is sufficient to meet the essential dual requirements of preventing process gas passing during turbine running, and maintaining the downstream blade skin temperature below the level specified for man-safe access.

This order follows on from the successful previous supply of 3 other guillotine dampers of similar configuration to the same site, which commenced in 2008 and is further strengthening the working partnership between DTL and Mjørud AS.  DTL have now successfully undertaken a number of projects with Mjørud AS,  in every case designing and supplying highly specified and specialised process solutions using our combined knowledge and experience gained over more than half a century.
