Bi-fuel boiler for solid biomasses, such as wood logs and pellet
Nominal output: from 9.5 to 30.5 kW
- Burner fan placed downstream the combustion chamber.
- Misaligned combustion with downward reversed flame, with triple modulation: - modulation through inverter on boiler temperature: to maintain the correct stoichiometric ratio - modulation on smokes temperature: to prolong the autonomy, guaranteeing the safety of the combustion - modulation on optic reading: to regulate the speed of the fuel feeding screw, so optimizing the combustion
- Low polluting emissions and very high efficiency: 89% with wood and 92% with pellet, that guarantees a rapid amortization
- Incandescent combustion chamber in special thermal stainless steel AISI 430, 8 mm thick,highly heat-stable and resistant to the high temperatures and to potential chemical aggressions
- Grate in thermal steel INOX AISI 310, 15 mm thick
- Lateral primary air chanels, with a thickness of 4 mm
- Vertical smoke pipes with mobile turbolators, automatically shaked by levers with timed activation, in order to increase the efficiency of the boiler (practical ashes removal from the front)
- Self cleaning pellet burner, in stainless steel AISI 304, placed behind the boiler
- Modulating fan with control by inverter, positioned in the suction side for optimization of the combustion
- Two independent loading feeding screw of safety reason
- Safety heat exchanger
- Pellet reservoir, optional: that can be placed on the RH or LH side of the boiler and automatically feeds the burner
- Wide wood storage, with front by-pass, for wood logs, to guarantee long intervals of operation
- Panel board BIOTRONIC for the management of: - automatic fuel commutation - operational states - safeties (acoustic and visual alarms) - values detected by elements of the installation - thermal solar circuit
- Reinforced photocell for the control of flame presence and intensity
- Ultra fast ignition (less than 3 minutes)
- Management of the power when in combination with a DHW storage tank
- Sensor for detection of minimum pellet level in the reservoir
- 4-star environmental certification
Options:
- Anti-condensation kit
- Inertial accumulators -Puffer for technical water and production A.C.S .: PFF PUFFER, MULTIPOWER, MULTIPOWER PLUS
- Predisposition for combination with automated system of pellet transport and loading.
