The Horizontal Membrane Water Wall Slag Cooler is a high-efficiency waste heat recovery and cooling equipment specially developed for circulating fluidized bed boilers, biomass power plants, waste incineration furnaces and coal-fired industrial boilers.

Different from traditional tube-type slag coolers, it adopts an integrated full membrane water wall cylinder structure, with the entire barrel wall serving as the heat exchange surface. High-temperature furnace slag directly contacts the water-cooled membrane wall to realize rapid cooling, meanwhile efficiently recovering high-grade waste heat from hot slag. It integrates slag conveying, cooling and waste heat utilization as one unit, solving the common defects of insufficient heat exchange, slag blockage, water leakage and short service life of conventional slag coolers.

• Full Membrane Water Wall, Ultra-Large Heat Exchange Area: The whole rotary cylinder is composed of welded membrane water wall panels, forming a seamless enclosed cooling channel. The effective heat exchange area is 2-3 times larger than multi-tube slag coolers of the same specification.
• Horizontal Layout + Low-Speed Rotation, Anti-Blocking & Low Wear: Horizontal installation design with low rotating speed (0.5-6 rpm adjustable by VFD). Slag moves forward without built-in spiral blades, reducing friction and abrasion.
• All-Welded Membrane Structure, Zero Water Leak Risk: Fully welded without gaps, avoiding tube-plate welding leakage problems. Extends cylinder body service life by more than double.
• High-Temperature Wear-Resistant Rotary Joint: Alloy static-dynamic double sealing rotary joint with built-in ash return structure for dust-free operation.
• Integrated Base, Easy Installation & Simple Maintenance: Mounted on integrated steel base with split flange design for easy disassembly and inspection.
• Complete Safety Interlock Protection System: Equipped with cooling water flow interlock, low water pressure alarm, overtemperature protection and emergency pressure relief valve.

• High-Grade Waste Heat Recovery: Cooling water outlet temperature reaches 85-95℃, reducing coal consumption for heating
• High Value Reusable Dry Slag: Cooled dry slag below 100℃ can be used as raw material for cement, road aggregate and energy-saving bricks
• Low Operation Cost: Low power consumption, low cooling water consumption, and few vulnerable parts
• Environment-Friendly Operation: Totally closed operation, no steam overflow, no dust flying, avoids sewage pollution

• Circulating Fluidized Bed (CFB) thermal power plants
• Biomass power generation & household waste incineration power plants
• Coal chemical industry, lime kilns, metallurgical furnaces
• Industrial coal-fired heating boilers, gangue power stations
