TLT-Babcock’s mechanical conveyor systems bring simplicity, reliability and significant cost savings to utility and industrial furnace ash removal operations. Regardless of the solid fuel being burned, TLT-Babcock can design and build the most cost-effective and reliable ash handling systems available.

TLT-Babcock’s Submerged Chain Conveyors can be applied to pulverized coal fired boilers, cyclone fired boilers, Integrated Gasification Combined Cycle (IGCC) units, and stoker fired boilers.

• Various capacities to handle a wide range of generation rates, unit availability over 99%
• Collects, quenches, and dewaters furnace ash for direct disposal
• Eliminates the need for ash dewatering bins or ash settling ponds
• Continuous operation, low power consumption and low water consumption
• Custom design, optimized for furnace configuration, minimal field assembly required
• May be supported on travel wheels to permit quick, unobstructed access into furnace throat
• Long life, abrasion resistant components , few spare parts necessary
• Maintenance friendly, simple operation
• Can receive economizer ash and pyrites eliminating storage and unloading equipment for same
• Retrofit existing water-impounded ash hopper and sluice system to improve personnel safety, eliminate high maintenance, lower parasitic power consumption and avoid higher capital expenditures with in-kind replacement of crushers, piping & dewatering bins

TLT-Babcock’s dry ash chain conveyors collect and transfer hot dry ash from circulating fluid bed boilers, PC fired boiler back-pass, economizer, air heater, and precipitator/baghouse hoppers.

• Various capacities to handle a wide range of generation rates
• Single and twin chain strands, designs available for steep incline conveying
• Gas-tight/low leakage construction
• Designs available for handling large particles
• Self-feeding designs available to eliminate material flooding at inlets
• Continuous operation, low power consumption
• Long life, abrasion resistant components , few spare parts necessary
• Minimal field assembly required, maintenance friendly and simple operation
• Retrofit existing high maintenance pneumatic systems
