Gasification Slag Glass Ceramic Electric Melting Furnace 3000kVA Vitrified Aggregate Equipment Solid Waste Recovery

Gasification Slag Glass Ceramic Electric Furnace Overview

The gasification slag glass ceramic electric melting furnace is a high-temperature vitrification furnace for the advanced resource utilization of coal gasification slag. The furnace melts gasification coarse slag and fine slag together with nucleating agents and flux at 1500-1650°C, converting the hazardous aluminosilicate waste into a homogeneous glass melt that is further processed into glass-ceramic panels or vitrified aggregate. Heavy metals in the slag are firmly locked in the glass network, delivering safe, high-value solid waste recycling for the coal chemical industry.

Core Features

• High-Value Recycling Route: Transforms low-value gasification slag into glass-ceramic building panels and vitrified aggregates, the highest-value product route among gasification slag utilization technologies.
• Heavy Metal Immobilization: High-temperature vitrification locks heavy metals and harmful elements into the glass network structure, making the product leach-safe and environmentally stable.
• Precise Melt Control: Electric arc heating with PID temperature control maintains 1500-1650°C melt conditions and uniform composition, ensuring defect-free glass-ceramic crystallization.
• Broad Feed Flexibility: Accepts both coarse slag and fine slag with varying residual carbon and composition, with a flexible proportioning system to stabilize the melt chemistry.
• Clean Production: Sealed furnace body, flue gas purification and closed-loop water cooling guarantee clean, safe operation meeting environmental discharge standards.

Main Technical Parameters

Production Process

Gasification slag is dried, ground and proportioned with nucleating agents and flux, then charged into the electric melting furnace. The charge is melted and homogenized at 1500-1650°C into a clear glass melt, in which heavy metals are immobilized. The melt is poured and formed into glass-ceramic panels through controlled crystallization, or granulated into vitrified aggregate for building materials and road construction.

Application Fields

• Glass-ceramic decorative panels and wear-resistant lining boards;
• Vitrified sand and aggregate for concrete, asphalt and backfill applications;
• Coal gasification slag harmless treatment and resource recovery projects.
