Weiss Boilers

Weiss’ Line of Wood-Fired Boilers: 1 MW to 15 MW

For power ratings above 15 MW, WEISS performs custom engineering to design and size the boiler. All our boilers use the latest technological innovations and deliver maximum performance.

We offer complete installations, including all components from storage silos to smoke treatment and deashing.

Operation of Wood-Fired Boilers

The design of our boilers uses the "8-point" operating principle:

Wood Fuel

• fuel storage unit (silo)
• fuel transferred to the boiler

Boiler

• fuel loaded into the foyer
• combustion
• heat exchanger

Waste Treatment

• smoke treatment
• ash collection

Operation

• automated systems / control system / control room

1. Fuel delivery using live-bottom trucks
2. Unloading pit
3. Main storage silo
4. Bridge crane and clamshell bucket
5. Buffer silo and push rake extractors
6. Chain conveyor
7. Damper and pusher
8. Furnace with dynamic grid
9. Low-NOx and low-CO combustion chamber
10. Exchanger with smoke tubes
11. Smoke recirculation

1. Automatic soot blowers
2. Furnace deashing and ash screw exchanger
3. Ash hopper
4. Economizer
5. Big Bag ash under economizer
6. Multi cyclone dust collector
7. Big Bag ash under dust collector
8. Baghouse
9. Big Bag ash under baghouse
10. Smoke extraction fan
11. Chimney
