KWB Powerfire power package is one of the most compact heating systems in the 150 to 300 kW power range. The KWB Powerfire can be fired with wood chips or pellets and is perfectly suited for supplying regional district heating networks and larger buildings and systems (contracting).

In this power range in particular, the payback period is particularly short. The "Energie Genie" (Energy Genius) and "Energy Globe Award" innovation prizes for efficiency and reliability are proof of the high product quality of the KWB Powerfire.

The rotary-grate combustion system is a unique system in which the fuel is pushed sideways into the pre-combustion chamber and conveyed onto a rotary grate.

The fuel is transported through the combustion chamber by means of grate rotation through approx. 270° before a special grate cleaning system handles ash removal. A sophisticated air duct with rotating flow ensures complete burnout, minimal emissions and the best possible removal of fly-ash particles in the downstream cyclone combustion chamber.
