Coal Gas Furnace

Gasifier & Aluminum Melting Furnace
A Coal Gas Furnace is an energy-efficient industrial heating solution that converts solid coal into combustible gas (producer gas) through a controlled gasification process. The resulting gas is then used as clean fuel for industrial furnaces, kilns, and heat treatment systems. It significantly reduces direct coal usage while lowering emissions and operational costs.
  • Free combination on demand to meet various working conditions

 Features.

  • High Thermal Efficiency

    Utilizes the heat of gasification and combustion, achieving fuel efficiency up to 75% compared to direct coal firing.

  • Clean Combustion Output

    Generates low-dust, low-sulfur producer gas, improving combustion environment and reducing flue gas pollution.

  • Continuous & Stable Gas Supply

    Designed for uninterrupted coal gas production, suitable for round-the-clock industrial operations.

  • Low Operating Cost

    Reduces fuel cost by utilizing readily available coal, especially in regions where gas or oil is expensive.

  • Easy Integration

    Can be integrated with reheating furnaces, annealing furnaces, rotary kilns, glass melting tanks, and other thermal systems.

  • Automation Ready

    Optional PLC-based control for gas output regulation, pressure monitoring, and safety interlocks.
