How a Continuous MSW Pyrolysis Plant Works
- Unsorted municipal waste is fed through a sealed, negative-pressure system.
- A pre-shredding system crushes the waste to even out particle size and improve conversion uniformity.
- The waste is heated under slight negative pressure with no oxygen contact, in a dual-stage pyrolysis + gasification process.
- Up to 85% of the input is converted into syngas, with the balance leaving as solid char/residue.
- Cleaned non-condensable gas is recycled to fuel the furnace, cutting external energy use by about 50%.
- Flue gas is treated through alkali neutralisation and an adsorption tower before Treated discharge; residue is discharged through a water-cooled screw conveyor.

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: Syngas, Char and Residue
- Solid char / residue - sealed discharge through a water-cooled screw conveyor.

Continuous vs Batch MSW Treatment
| Continuous (PC) | Batch (PB) | |
|---|---|---|
| Scale | ≥10,000 t/year | ≈3,000 t/year |
| Operation | 24/7 | Single furnace per day |
| Automation | High (1-2 operators) | Moderate manpower |
| Feedstock | Unsorted / pre-shredded MSW | Sorted / smaller volumes |
Choose continuous for centralised treatment of medium and large urban waste; choose batch for smaller or lower-budget projects.
