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

Raw Material Preparation: Crushing & grinding → Batching & pelletizing → Drying.
Main System: Furnace body (steel shell + refractory lining) → Electrode system → Power supply system → Water cooling & flue gas cleaning.
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.
