Details of our unique Heating Technology
Wood chip Boilers
1. Grate Movement: Double Rotary Grate
The grate consists of two consecutive and stepped grates which can move independently. During combustion the grates are moved accurately to ensure a homogeneous firebed.
2. Rear Rotary Grate: Double Rotary Grate
Pellets as well as Micanthus can be combusted easily. If regular wood chips are used, only the rear de-ash grate opens. Ash is falling down and embers remain.
3. Open Both Grates: Double Rotary Grate
If the boiler is completely cold a full cleaning process is executed prior to start. Both grates open, cold ash and all foreign objects like stones, nails, etc. are being disposed.
4. Breaker Function: Double Rotary Grate
For miscanthus etc, the "Breaker Function" of the grate forces clinker down into the ash auger.
Up to 95% efficiency of the boiler
With efficiency of up to 95% and even above, Hargassner Wood chips boiler are beneficial for lowest fuel consumption as well as with lowest emissions.
Fuel quality detection by Lambda sensor
The control unit uses the lambda sensor to detect the relevant calorific value and regulates hat optimal fuel / air mixture.
The unique boiler control with touch screen offers the most modern user-comfort and controls the whole combustion process. Furthermore, all heating circuits are regulated by outside-temperature control and the HWT is controlled with a temperature-difference-regulation.
Adapt your boiler quick and easy. Change settings on heating circuits, heating times, temperatures, …
Combustion chamber fully refractory-lined
Refractory Lined combustion chamber guarantees high combustion temperatures through optimum heat storage (already at part-load), which minimises the irgnition procedure and recduces emissions.
Firebed height monitoring
Through the exact and contact-free firebed-height monitoring system with sensors, the most effective combustion condition (depending on fuel quality) is detected. Your heating system is always working withi the required heat output at optimal combustion values.
Standard Feature Fluegas - Recirculation
To reduce clinker creation in the ash, Hargassner offers a flue gas recirculation, especially for very dry fuel or material with a low ash melting point. The resulting ash can be easily removed out with the ash extraction auger.
Touch Control (integrated)
The control system is characterised through its exeptional design and simple handling. Navigation is very sophisticated. You visually recognise the current status of the boiler, the accumulator and HWT as well as all heating circuits.
Ash Extraction System (automatic)
The all new ash extraction systems results in very long maintenance intervals. The ash-box can be mounted left and right hand side of the boiler. Consists out of a 300l ash-box and flexible auger.
Rotary valve in Z-shape
The Z-shaped rotary valve is designed specifically for wood chips. Guarantees 100% burn-back safety, Depth of chamber 18 cm. Especially for extra long wood pieces with smooth operation. With hardened cutting edges
