Horizontal Multi-Tube Water-Cooled Slag Cooler with Dense Tube Bundle and Wear-Resistant Design for Rotary Operation

Our Horizontal Multi-Tube Water-Cooled Slag Cooler is professional bottom slag processing equipment specially designed for CFB circulating fluidized bed boilers, biomass power plants, waste incineration stations, and coal-fired industrial boilers.

Adopting a horizontal rotary cylinder structure with built-in dense layered cooling tube bundles, this equipment enables full-contact heat exchange between circulating cooling water and high-temperature furnace slag. It integrates high-temperature slag cooling, stable slag conveying, furnace ash transportation, and slag waste heat recovery into one comprehensive system.

• Dense Multi-Tube Bundle Heat Exchange Structure: Uniformly arranged internal cooling tubes significantly expand heat exchange area, providing higher efficiency than traditional sleeve-type slag coolers. Rapidly cools 900–980°C furnace slag below 100°C for fully qualified dry slag discharge.
• Stable Horizontal Rotary Operation Design: Horizontal layout with low-speed rotation ensures even material advancement without accumulation or blockage, minimizing equipment failure rates during continuous operation.
• Wear & High-Temperature Resistant Components: Critical parts including rotary joints, end covers, and drive shafts use high-temperature alloys to prevent deformation, cooling water leakage, and ash overflow under sustained thermal loads.
• Variable Frequency Adjustable Capacity: VFD driving system allows flexible adjustment of cylinder rotation speed to match slag discharge volume with actual boiler operating load.
• Convenient Maintenance & Installation: Modular split structure supports partial disassembly and replacement of cooling tubes and vulnerable accessories. Standard base frame requires minimal civil foundation work.
• Complete Safety Protection: Includes water flow interlock protection, low water pressure alarm, over-temperature protection, and pressure relief valve to prevent dry burning and equipment damage.
