Operating Principle

  • DRY Material Extraction, Conveying and cooling in one stage
  • Continuous Extraction
  • Conveying rate: > 100 t/h
  • Length: As per ambient plant conditions
  • Range of width: 1.6 m – 2.2 m
  • Utilises ambient air as the cooling medium, typically 1% of the total air needed for the combustion process
  • Inclination angle up to 45 °

Technical Summary

DRYCON™ – a steel plate conveyor – is used to automatically convey and cool the bottom ash by means of ambient air. The plate conveyor is designed for operation under difficult conditions, like extreme temperatures and strongly fluctuating quantities of bottom ash. DRYCON™ can be retrofitted into existing facilities where space is at a premium.

Key Industies: Power Generation, Waste-to-Energy, Biomass, Other Industrial Processes

Key Features

  • High conveying capacity
  • The modular construction principle allows flexible adaption of length-width ratio guaranteeing efficient material cooling at a maximum extraction rate
  • Impacts of large ash lumps are directed onto impact beams – no stress to any important moving parts
  • Less wear due to no friction moving parts
  • High inclination possible resulting in the use of only one conveyor conveying directly to the silo

Product Benefits

  • No water required: protects the environment and avoids effluent treatment costs
  • Heat input from reburning of ash increases boiler efficiency reduces coal usage and CO emissions
  • Sellable by-product: Lower carbon in the ash increases ash quality & value
  • Low life-cycle costs
  • Ability to maintain on-load resulting in increased boiler availability
