The sustainable solution: when production waste becomes a resource.
The flat boiler with moving grate or with steps is particularly suitable for more complex fields of application thanks to the possibility of using wood fuels with a high content of ash and water and special fuels such as waste of grain, stalks of corn, miscanthus, hay or straw pellet); this ensures genuine manufacturing advantages for energy companies in terms of energy efficiency, cost savings and sustainability.

Low Nox Technology
The boiler boasts an advanced combustion technology that combines the advantages of the auger-fed burner with those of the moving grate with minimum emission values, maximum efficiency, savings and a perfect interaction of the construction and adjustment elements.
A feeding auger transports the fuel into the pre-combustor compartment where it is pre-dried; it is subsequently transferred to the moving grate, with a solid structure in chromed steel and high-alloyed cast iron elements, arranged so as to minimize fuel loss.
Long life, immediate availability of the system and ease of maintenance are guaranteed by the wheeled structure and by the elements of the grid that can be replaced individually.
The grid is divided into sections with two separately controllable primary ventilation zones for uniform combustion air distribution and turbulence-free gasification, and is operated with a hydraulic system.
The progress phases are automatically adjusted to the power demand.
The refractory cement vault above the grate and with fuel-dependent execution ensures a high combustion temperature even in the presence of wet fuel. The secondary air that flows into the post-combustion chamber allows a gradual and complete combustion with minimal emissions. The ashes are conveyed slowly from the grate to the end of the same (where automatic removal takes place) and are transported to the ash tray. Under the grate it is possible to install an ash removal device (on request).
Intelligent regulation of the entire system
The digital modulating regulation, integrated as standard on medium power boilers, guarantees perfect operation and constant control to meet the various usage requirements; it controls and optimizes the combustion process with the possibility of regulating power, combustion temperature, depression, residual oxygen content and the amount of air supplied to the combustion system. The system is displayed on a touch-sensitive display that can be used with great simplicity.
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
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.
