Industrial pellet systems for high performance

The efficient use of an energy source other than fossil fuels, combined with the most modern technologies, allows the construction of industrial wood pellet or wood pellets that meet the needs of structures characterized by a high demand for thermal energy: industries, companies of the manufacturing sector, public bodies, greenhouses, district heating and cogeneration networks.

Industrial wood or wood pellet boilers guarantee the highest levels of efficiency and a significant reduction in costs and contribute decisively to environmental sustainability for the responsible management of natural resources.

The Tatano industrial heat generators are comparable to a gas or oil heating system with fully automatic operation.

Tatano follows every stage of the installation, from the first feasibility study to commissioning.

Innovative, efficient and clean combustion technology

The operation of the high-capacity industrial pellet boiler, with regulation of the modular power and the application of the three-stage direct combustion principle, guarantees high efficiency and low emission values. It is equipped with a permeable combustion chamber, with a consequent fast production of power, able to operate a primary subdivision of the air, in order to reduce NOx emissions in the exhaust gases.

The combustion module runs entirely from the secondary and tertiary air injected into the flame zone with a high turbulence system and with the independent regulation by inverter, in a wide modulation field and with reduced electrical consumption.

The fuel is loaded from the bottom inside the fixed brazier through the feeding auger, the sub-grid is divided into watertight compartments for an accurate and uniform distribution of the primary air and a gasification without turbulence.

The boiler body and the heat exchanger, with inverted flue gas path, are entirely covered with water so as to maximize the heat exchange and reduce the temperature of the external layer with minimal dispersions.

The refractory cement coating of the various zones guarantees high efficiency and reduced wear of the system. The combustion ashes are removed and transported automatically in an external container by extraction augers.

Safe and reliable operation

Tatano heating systems meet the most stringent safety standards. High-tech safety devices guarantee reliability and operational safety in every phase of boiler operation


Intuitive and versatile adjustment of the system

The entire control system is mounted as standard on large power boilers and is already wired.

The system has a digital modulating system, completely programmable according to the customer’s needs, which ensures a perfect combustion thanks to the regulation of the combustion air, fuel and exhaust gas temperature.

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.
