Product Description

Equipment Introduction & Technical Parameters


1. Equipment Type & Application


For the above four types of solid waste, the mainstream equipment includes submerged arc furnace (mineral heat furnace), DC melting furnace, rotary hearth furnace + electric furnace combination line, which achieve both harmless disposal and resource recovery.


Solid Waste Recommended Equipment Main Purpose Typical Process
Fly Ash DC Melting Furnace / Closed Submerged Arc Furnace Solidify heavy metals, decompose dioxins, separate molten salt Melting at 1400–1500℃ → Salt recovery → Slag solidification
Aluminum Powder / Aluminum Ash Submerged Arc Furnace / Aluminum Melting Furnace Recover metallic aluminum, remove impurities High-temperature melting → Aluminum settling → Reuse
Red Mud RHF + Melting Separation Furnace Recover iron, produce hot metal, utilize slag Pelletizing → Prereduction → Melting separation
Coal Gangue Submerged Arc Furnace / Electric-assisted Kiln Make bricks, ceramsite, waste heat power generation Briquetting → Sintering → Densification


2. General Process & Structure


  1. Raw Material Preparation: Crushing & grinding → Batching & pelletizing → Drying.
  2. Main System: Furnace body (steel shell + refractory lining) → Electrode system → Power supply system → Water cooling & flue gas cleaning.
  3. Key Reaction: High-temperature reduction/melting → Slag-iron separation → Tapping → Waste heat recovery.


3. Typical Technical Parameters


3.1 Electrical Parameters (General)



Parameter Range Remarks
Transformer Capacity 6,300 – 40,500 kVA Higher for red mud/fly ash
Secondary Voltage 80 – 290 V Low voltage, high current
Secondary Current 20,000 – 80,000 A Three-phase balanced
Power Factor ≥ 0.9 With reactive power compensation

3.2 Furnace & Electrode Parameters (33,000 kVA)



Parameter Value
Furnace Shell Diameter 10 – 12 m
Furnace Chamber Diameter 7 – 9 m
Lining Thickness 300 – 500 mm
Electrodes 3 pieces, Φ1.2 – 1.5 m
Furnace Top Temperature 900 – 1100℃

3.3 Process & Consumption Indexes



Material Melting Temp Daily Capacity Power Consumption Key Index
Fly Ash 1400–1500℃ 50–200 t/d 2,400–3,200 kWh/t Heavy metal leaching standard; dioxin decomposition ≥99.9%
Aluminum Ash 1200–1400℃ 80–300 t/d 1,800–2,500 kWh/t Al recovery ≥98%
Red Mud 1450–1650℃ 100–300 t/d 2,800–3,800 kWh/t Metallization rate ≥90%
Coal Gangue 1050–1300℃ 200–500 t/d 35–100 kWh/t High strength brick/ceramsite


4. Advantages


  • Strong adaptability: Handles various solid wastes.
  • Environmentally friendly: High temperature decomposes dioxins, stabilizes heavy metals.
  • Resource recovery: Recovers Fe/Al, produces building materials.
  • High automation: PLC control for temperature, electrode, feeding.


5. Selection Suggestion


  • Small scale (<100 t/d): 6,300–12,500 kVA
  • Medium (100–300 t/d): 12,500–25,000 kVA
  • Large (>300 t/d): 25,000–40,500 kVA

Closed DC furnace is preferred for fly ash for strict emission standards.


6. Typical Applications


  • Red Mud Project: 33,000 kVA submerged arc furnace, 200 t/d, hot metal + slag for rock wool.
  • Fly Ash Melting: DC furnace, salt recovery ≥95%, slag for road base.
  • Coal Gangue Utilization: Bricks + waste heat power generation.
