Product Description

Product General Description

The scraper slag conveyor is a kind of bottom slag handling system that is widely applied to constant transport of bottom slags of the boiler in large coal-fired power stations.

Bottom ash continually falls from the furnace throat, through the insulated bottom ash chute, and into the water-filled submerged conveyor trough. Cooled ash is conveyed along the bottom of this trough by conveyor flights attached at both ends to continuous loops of conveyor chain. As the ash-laden flights leave the water-filled trough and travel up the dry incline, the ash drains and dewaters itself. The dewatered ash is discharged to a take-away conveyor or storage area. The conveyor flights return in a lower compartment, which is open for maintenance.

Performance Specification

Continuous ash removal up to 100 TPH

Less energy and water consumption than sluice systems

Design Features

Upper trough (wet) is lined with thick abrasion-resistant steel plate for maximum strength and durability

Bottom trough (dry) is lined with the wear-resistant rails for maximum strength and durability

High-strength, robust round chain link is case hardened to designed specification (approx. 700 BHN) for longer-life durability.

Drive sprocket teeth are made from alloy steel and case hardened for maximum strength and durability

Flights are constructed of rectangular steel tubing, instead of angle iron, to greatly resist and avoid derailment or bending.

Submerged idlers are cast from corrosion resistant material and heat treated for superior life and reliability

Structural support designed to withstand upset conditions.

The chain tensioner uses a hydraulic cylinder to maintain constant chain tension which extends the chain life and eliminates weekly adjustments common.

An integral indicator provides visual reference of chain wear. A linear positioner provides an instant alarm if the chain breaks.

Simple, direct drive soft-start hydraulic motor/reducer provides superior performance and less maintenance over variable speed drive motors.

The conveyor is designed for either variable speed operation, or for two pre-set speeds: normal mode and “catch-up” mode. The higher speeds are used when the unit has been shut down temporarily and a large volume of ash has been collected in the upper trough.

Modular design simplifies field erection and reduces installation cost

Optional rollout wheels allow direct access to the boiler throat during a shutdown
