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.

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

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
