Solving Ash Handling Problems

Integrated, Custom-Designed,
Mechanical Ash Handling Systems

Wet Ash Handling SystemsWet Ash Handling: A refractory-lined bottom ash chute forms the boiler seal and directs bottom ash to the water-filled upper compartment of the submerged chain conveyor.

There, ash is cooled, conveyed, and dewatered for storage or transport. Bottom ash conveyors are available in varying sizes and capacities ranging from under 5TPH to over 50TPH.

Dry Ash Conveying SystemsDry Ash Conveying: Totally enclosed, dust-tight, air-tight dry drag chain conveyors receive fly ash through seal valves or mate directly to fly ash hoppers.

Available with single-strand and double-strand chain, top or bottom conveying configurations, horizontal or inclined conveyors up to 35° incline, over 200 ft in length. Water jacketed conveyor troughs allow conveying and cooling of ash at temperatures over 1500°F.

ash conditioning systemsAsh Conditioning: Twin-shaft paddle type fly ash conditioning systems used for wetting and mixing of ash and other dusty, abrasive materials.

Variable-speed rotary feeder precisely meters ash flow. Totally enclosed twin-shaft mixer uses low speed counter-rotating mixing action to thoroughly blend and mix ash as it is moistened by wetting sprays. Sizes from 5TPH to over 300TPH.

Ash Storage SystemsAsh Storage: Shop-assembled or field-welded surge bins and storage silos.

From 150 feet to over 30,000 feet, including mechanical or pneumatic silo extraction systems, level detection, fire- and explosion- suppression systems.



Mixer Unloader Systems
