Fluidized-Bed Gasification and Melting Furnace

Process Flow Diagram

Overview

Our fluidized-bed gasification and melting furnace employs a high-temperature combustion and melting process in which waste is gasified in the fluidized sand layer and the gas then reacts with air, eventually producing slag from melted ash. The facility is capable of performing this process without a fossil fuel supply, using only waste as an energy source.

Features

1. High Resource Recovery Efficiency

The facility recovers highly recyclable materials, such as steel and aluminum, from waste while producing slag from incineration ash. This means that the combustion process leaves nothing to be disposed of and effectively renders all waste incineration residues into reusable resources, realizing “zero emission” status.

2. Superior Power Generation Efficiency

The lower volume of corrosive gas produced supports the use of a high-temperature high-pressure boiler that, in turn, allows for high-efficiency heat recovery for power generation.

3. High Treatment Capacity

Its ability to treat a variety of waste extends to waste once disposed of in landfills, enabling the reclamation of final disposal sites.
