The Submerged Scraper Conveyor (SSC) has been supplied as an alternate to traditional wet bottom ash hoppers and slurry systems. The SSC can be used in both new applications and as an upgrade on bottom ash hopper retrofit projects. Kalpataru is a market leader in Submerged Scrapper Conveyor system. Kalpataru's SSC is used for the continuous removal of bottom ash from conventional Pulverized Coal fired boilers and is particularly suited when high ash rates and boiler slag falls are expected. The SSC is a heavy duty dual drag flight chain conveyor. The conveyor is submerged in a water trough below the furnace which quenches hot bottom ash as it falls from the combustion chamber. The bottom ash is then dewatered as it travels up the inclined section before it discharges. Double roll crushers can be used for final particle reduction at the discharge of the SSC. The discharge of the SSC can be fed into removable containers or onto a transfer conveyor to storage, for by-product reuse or landfill.
