Retrofit of ash conveyor

Application

Ash Conveyor at Coal Power Plant in South America.

Description of the problem:

  • Frequent chain breakage
  • Frequent scraper bar breakage
  • Frequent chain stoppage
  • High maintenance demand

RUD Solution:

  • Measurements were taken by RUD Engineer
  • The geometry and the casing allowed the retrofit with RUD round link chain system
  • The existing casing were adjusted for the new RUD system
  • Replacement of existing pin & bush chain into RUD round link chain system
  • Installation of RUD round link chain 19x75 and SSRF-system

Result:

RUD focus was to reduce the maintenance activity on the chain with lower cost for the cusomer and trouble-free performance.

Retrofit of coal feeder conveyor

Application

Coal Feeder Conveyor at coal fired power plant in Australia.

Description of the problem:

  • The corrosion of pin & bush chain links causes knuckling and frequent chain replacement
  • The time and the labour for major outages has to be shortened

RUD Solution:

  • Retrofit of existing coal feeder conveyor
  • Replacement of pin & bush chain by RUD round link chain 14x50
  • Installation of reversing shafts and grooved idlers
  • Installation of drive shafts and pocket wheels
  • Installation of RUD scraper bar MEE-T

Result:

  • Short-term project time
  • Excellent performance of new chain system

Retrofit of submerged scraper conveyor

Application

Submerged Scraper Conveyor in at coal fired power plant in Germany.

Description of the problem:

Heavy duty ash and slag leads to  increase of conveying capacity and drive power.

RUD Solution:

  • Retrofit of existing submerged scraper conveyor to increase conveying capacity
  • Upgrade of round link chain 26x100 into 30x120 in existing casing
  • Installaton of RUD submerged overhung idler (SOI 30)

Result:

  • Short-term project time
  • Excellent performance of new chain system
  • No shutdowns due to overfilling of conveyor
