Efficient and clean combustion
Consolidated two-stage combustion technology, exchange surfaces and optimized geometry of the combustion chambers, regulation of the modular power and primary and secondary air supply regulated separately: thanks to these elements, optimal combustion, high performance and compliance with the limits of polluting emissions imposed by environmental regulations.
A conveyor screw constantly supplies the fuel in the burner compartment. The phon device is only activated during the ignition phase with consequent power saving.
The variable speed of the fuel feed and the inflow of air coming from the two regulated circuits, provide for drying and complete degassing (primary combustion). The combustion gases then pass into the combustion chamber, where it is mixed with secondary air and the flame production.
The boiler is equipped with a smoke tube heat exchanger completely immersed in the water mantle for maximum heat transfer and efficiency.
At the end of the burner, the motorized extraction augers remove the combustion ash by transferring them to the appropriate containers. Optimal system performance is achieved through the construction and procurement of all components from a single supplier
An adjustment for every need
The centralized regulation device, fitted as standard on medium-power boilers, with reduced wiring requirements, is a digital modulating plant regulation, fully programmable according to requirements, which ensures optimal combustion thanks to the exact setting of the air-to-air ratio combustion, exhaust gas temperature and fuel.
Pneumatic cleaning system
A clean heat exchanger is crucial for ensuring the efficiency and life span of a boiler.
The pneumatic cleaning system eliminates the ashes in the exchanger through short compressed air blows at regular intervals and which propagates with a shock wave along the tubes, cleaning the walls from the deposited particles.
In this way maintenance interventions are significantly reduced
Brazier cleaning system
A careful cleaning around the brazier ensures an excellent combustion.
The system can be installed as an accessory in cases of use combustibles with a high ash content.
Depending on the size of the system, it is possible to combine the ash removal system of the combustion chamber with adjustable air injectors (already present as standard in some models) that automatically emit air jets and convey the ash towards the channels of collection which is taken from the extraction screws.
Automatic ash removal
Centralized or separate automatic removal of ash from the combustion grid or multi-cyclone. In the centralized variant the mechanical removal by hydraulic rakes or extraction screws conveys the ash from the combustion grid and from the multicyclone to an external common container. In the separate variant, the ash from the combustion grid and the multi-cyclone is transported in separate containers.
Economizer for heat recovery from smokes
A part of the exhaust gas with a reduced oxygen content returns to the combustion chamber.
Thanks to the mixture with the primary air it guarantees the complete gasification of the fuel, it allows to lower the temperature of the combustion chamber, to reduce the particulate emissions and ensure a long life of the combustion system.
The yield is improved of about 3-7%.
Exhaust gas recirculation
In the presence of problematic fuels, it is possible to install an exhaust gas recirculation device, to reduce the temperature of the combustion chamber and lower the thermal NOx:
- With fuels with a low ash melting point
- With dry fuels with a high calorific value
In this way a high yield is guaranteed respecting the plant and without the formation of waste.
Exhaust gas deduster
The dust collector minimizes dust emissions by filtering the exhaust gases. Primary mono, bi- and multi-cyclone filtering systems are supplied completely separated or integrated on the boiler.
The dust collector is supplied complete with fan positioned on the sides or in the upper part, with electronic control and management. The integrated multi-cyclone on the boiler can be equipped with automatic removal of the fly ash by an auger and a star valve as an accessory.
The secondary filtration systems for the control of the particulate emissions of the wet scrubbers’ type are sized and designed according to the specific needs of the plant in the presence of problematic fuels, very dry and dusty
Remote Control
The app 4 heat offers new possibilities for controlling and managing the remote heating system via internet routers (Wi-Fi) and the Cloud server.
If the boiler setting is connected to the internet, all the heating settings can be viewed and changed directly from the smartphone, tablet or PC. In this way, it is possible to have the heating under control wherever you are.
In addition, the remote access solution allows access to the full range of services offered by the Tatano technical assistance service.
