Retrofit of Biomass Ash Conveyor

Application

Ash Conveyor in Biomass power plant (farm waste) in North America.

Description of the problem:

  • Three separate farms in Leamington Ontario with problems in ash conveyor manufactured by Hurst boiler
  • premature chain wear, uneven wear between the two strands, large amount of maintenance and down time
  • Links (2-4) are removed each month from the chain and the chain is lasting about 18 months before replacement is required
  • Current system is a 14x50mm through hardened chain with shackles

RUD Solution:
