Wood boiler POWERCHIP 75

for heating onlyresidentialindoor

Our Powerchip heating systems, with step grate technology, effectively combine maximum economy and minimum emissions. Subject to approval and model, these boilers can also be converted to alternative fuels, such as pellets, miscanthus and plant matter. The woodchips are gasified on the step grate, where primary air is supplied, at an ember bed temperature of around 850 °C. The amount of combustion air and fuel charge is regulated by means of a lambda probe, so that the system achieves a level of efficiency of up to 94 %. With the aid of secondary air, the generated combustion gases are cleanly and efficiently converted into energy in a large rotating combustion zone. The pioneering discharge system operates with slow turning motors that consume very little power and develop extremely high torque of up to 1200 Nm. In addition, the progressive screw conveyor incline and the optimised trough geometry ensure the highest operational reliability. Operating POWERCHIP heating systems is particularly easy thanks to the well thought-out and user friendly touchscreen interface. All settings and scans of system data can be made in just a few steps. An ash screw conveyor transports the ash from the self-cleaning step grate into an especially large moveable ash box. Dust from the automatic heat exchanger cleaning process is also continuously moved into a separate, easy-to-empty container. The optional automatic vacuum ash discharge into a 200 litre drum is highly convenient.
