Municipal Solid Waste Pyrolysis to Electricity System

The Pyrojin MSW-to-electricity pyrolysis equipment converts urban waste into usable electricity. It processes mixed municipal solid waste - organic matter, plastics, textiles and more - through anaerobic medium-temperature pyrolysis, turning the waste into pyrolysis oil, combustible gas and recyclables. The oil and gas are then used for power generation, while by-products such as metals are recovered and recycled. The result is a waste-reduction rate over 90% and a stable electricity output that can supplement local grids.

How an MSW-to-Electricity Pyrolysis System Works

1. Mixed MSW (organic matter, plastics, textiles) is fed continuously through a sealed, negative-pressure system.
2. The waste is heated under anaerobic, medium-temperature pyrolysis conditions with no oxygen contact.
3. Pyrolysis vapour is separated into pyrolysis oil (liquid) and combustible gas (non-condensable).
4. The oil and gas are used for power generation; metals and other recyclables are recovered.
5. Non-condensable gas is cleaned and recycled to the furnace, making the system energy self-sufficient.
6. Flue gas is treated through alkali neutralisation and an adsorption tower, and residue is discharged through a water-cooled screw conveyor.

Models and Specifications

Series capacity covers 20-50 t/d; PC-30/40/50 are the three standard models. Main reactor runs at slight negative pressure, horizontal rotation 0.3 rpm, circulating-water cooling, noise ≤85 dB, installation footprint approx. 50 m × 20 m, 1-2 operators per shift.

Outputs: Electricity, Pyrolysis Oil, Gas and Recyclables

• Electricity - stable output to supplement local grids or captive use.
• Pyrolysis oil - recovered liquid fuel.
• Combustible gas - recycled for process heat and power generation.
• Recyclables - metals and other by-products are recovered and recycled.

Continuous vs Batch Waste-to-Energy

Choose continuous for grid-connected or round-the-clock power projects; choose batch for smaller, modular needs.
