Hargassner boiler design

Energy-saving ignitionDue to the new design of the ignition element, electrical power consumption has been reduced to just 300 W (up to 1000 W less) and, at the same time, the efficiency of the ignition process has been increased.

- Electricity savings of over 88 % - Intelligent ignition monitoring - Completely silent

Full refractory-lined combustion chamberwith flame concentration jets for optimum post-combustion

The refractory combustion chamber guarantees high combustion temperatures by optimum heat storage (even at part-load), minimises the ignition procedure and reduces emissions.

Firebed monitoringThrough the precise and contactless firebed-height monitoring system, the most effective combustion conditions (depending on fuel quality) are detected. Your heating system is always working at optimum combustion values for the required heat output.

Perfect cleaning increases efficiencyThe new cleaning method cleans ALL heat exchanger tubes at regular intervals - NOW the down draught is also cleaned (Stainless steel turbulators). The heat exchanger is cleaned with turbulators made out of heat-resistant material.

The turbulators remove the fly ash from the pipes, which falls down into the ash extraction auger. The result is easier cleaning and increased overall efficiency.

Furthermore, the grates are able to level the firebed to ensure a homogeneous combustion process.

Unique double rotary step grateThe grate consists of two adjucent stepped grates which can be moved independently.As a result, wood pellets, as well as other agricultural fuels, may be burned efficiently.

If regular wood pellets are used, only the rear de-ash grate opens. The ash falls down and the embers remain.

If the boiler is completely cold, a full cleaning process is executed. Both grates rotate and all foreign objects like stones, nails, etc. are removed in addition to the cold ash.

For pellets made out of miscanthus, the "Breaker Function" of the grate forces clinker down into the ash auger.

Energy-saving OperationSpeed-controlled EC exhaust fan with negative pressure monitoring

For the ECO-PK Hargassner uses the energy-efficient EC exhaust fans. The main advantage of this GreenTech EC technology is the significantly higher efficiency rate of up to 90 %. This saves energy and electricity. The negative-pressure unit constantly measures the pressure conditions in the combustion chamber. The Lambda-Touchtronic uses this data to control the speed of the draught fan, thus keeping the negative pressure at an ideal level. This concept ensures combustion with minimal exhaust gas temperatures and therefore maximum efficiency.

Recirculation to reduce clinkerTo reduce clinker in the ash, Hargassner offers flue gas recirculation as standard.Due to the cooling of the firebed during combustion, the relatively low ash melting point of very dry material can be reduced. The ash can be easily removed into the ash extraction auger.

ECO-PK 70-120 kW

Pellets suction process also possible during combustionThe double rotary valve with ventilation allows refilling during the regular combustion process which means no loss of power and therefore optimum heat supply.

Pellet suction up to 20mThe Hargassner pellet vacuum turbine sucks the pellets into the hopper; either from an extracting auger, a single, double, three or four point vacuum feeding system, or a bag silo. A hose length of up to 20 m makes it easy to overcome architectural barriers and handle complex boiler and storage room combinations. To turn off the vacuum turbine after refilling the hopper, a level detector is integrated.

From the hopper into the double rotary valveA constant amount of pellets fall through the double rotary valve and the stoker auger transports the pellets into the refractory-lined combustion chamber.

Ash suction offers maintenance intervals of up to one year An optional ash suction system is available which sucks ash into a 300 litre bin.

The suction system transports the ash through a steel pipe system from the boiler room into the ash bin, which is located in a roofed outdoor area. The ash bin can be emptied once a year

using a tractor or front loader. Hargassner’s superior and intelligent cleaning technology is easy and efficient to use.

Integrated back end protection An integrated back end protection with energy-efficient pump and motor mixer is available.

- fast and easy to assemble - compact and inexpensive
