Small Waste-to-Energy (WTE) Plants

Small Waste-to-Energy (WTE) Plants

Small waste-to-energy (WTE) plants are facilities that incinerate non-recyclable waste to generate electricity. They are typically modular in design for flexibility. They operate by burning waste to generate steam, which drives a turbine to generate electricity. They are equipped with advanced flue gas cleaning and energy recovery systems to minimize environmental impact. The advantage of these plants is that they reduce the amount of waste sent to landfills and avoid the economic and environmental costs of transporting waste over long distances.

How It Works: Waste Receiving:

Waste is delivered to the plant by truck and stored in an enclosed bunker. This area is typically maintained at negative pressure to prevent odors from escaping.

Combustion:

A grab crane transports the waste into the incinerator, where it is burned at high temperatures (between 850 and 1,000°C).

Steam Generation:

The heat generated by combustion boils water in a boiler, producing high-pressure steam. Power Generation: The steam drives a turbine connected to a generator, generating electricity.

Flue Gas Treatment:

Advanced air pollution control systems remove pollutants from the flue gas before it is discharged through the chimney. Ash Recovery:

Ashes are collected and ferrous metals are typically recovered for reuse. Remaining ash can be reused as building materials or safely landfilled. Waste-to-Energy Plant - Wikipedia: If the ash is deemed hazardous, it can only be disposed of in a well-designed landfill to prevent contamination.

Benefits of Small Plants: Reduced Transportation Costs:

Small, localized plants reduce the need for long-distance waste transportation.

Flexibility:

The modular design allows for a wider variety of plant sizes, including mobile options, and greater flexibility in managing waste at different or remote locations.

World's Most Advanced Waste-to-Energy Technology:

Fireprint (China) technology utilizes low-temperature magnetic gas pyrolysis to reduce combustible waste to carbonized waste. The pyrolysis process produces residual combustible gas, which drives a generator. The system incorporates a large number of flue gas treatment units, reducing harmful gas emissions and being environmentally friendly.

Improved Waste Management:

They provide an alternative to landfilling non-recyclable waste.

Energy Recovery: They recover energy that would otherwise be wasted and can offset fossil fuel use.
