Boiler biomass powerefire KWB                  KWB

                      


The KWB powerfire is equiped with a fire shutter (and optionally with a cell wheel sluice). The stocker channel and the hopper are completely sealed up to the fire shutter. This ensures that backfire is extinguished due to lack of air. The fire shutter has been tested as a backfire-protection device (BPD) as specified by TRVB H118 (Fire protection policy).

The shutter is opened and closed by a servomotor. Fuel conveyance only starts when the shutter is completely open.
In case of faults or power failure, the shutter closes automatically. When in operation, the control system prevents
burnback in the stoker chanel by feeding fuel. In addition, a sensor monitors the temperture in the stocker channel
area.There is a safety temperture limiter(STB), this system shuts down the heating system if the boiler temperature
should exceed 95°C. So, the fuel conveyor will be switched off, the fire shutter locks automatically, the fans are
switched off and alarm will be displayed on the boiler control unit.Also, there is an emergency fire extinguisher
in the stocker screw channel serves as a last instance of protection in special situations. It consists of a temperature
sensor witch opens a valve at 95°C. The temperature sensor is mounted on the screw channel in a thermally conductive manner.
Under normal conditions, the valve blocks the hose connection between a 10-litre water canister and the screw channel. If there is backfire, the channel is flooded and the fire is extinguished. As an additional safety devive, KWB systems have a float switch installed in the water canister. The float switch shuts down the system if the water level drops (under the minimum level). The extinguishing device is a backfire protection device (BPD), a pyrostat in accordance with TRVB H 118 and it also functions if there is a power failure. Also, there is a thermal discharge safety valve as an integrated safety device against overheating of the boiler. The thermal discharge safety switch is triggered if the temperture exceeds 95°C.
Trigger factors cloud be sudden shutdown if there is failure of the boiler pump or there is black-out or there is defect boiler temperature sensor.
Also, there is a temperature monitor in the fuel storage whitch sends of a fault message when a temperature of 70°C is
exceeded and shuts down the boiler. Also, there is a overfill protection shuts down the system if the conveyor is overfilled whitch causes the maintenance cover to lift.
