Advanced technology for sustainable waste development

Mobile flat or step grate boiler is particularly suitable for the more complex fields thanks to the flexibility of use of wood fuels with a high content of ash and water and of special fuels (grain waste, corn cores, miscanthus, hay or straw pellets), ensures companies a double advantage: sustainable development and environmental protection. Suitable for continuous use, it is the answer to large projects, for large thermal power stations of industries, companies or district heating systems; represents an advantageous solution for municipalities and energy suppliers for the production of electricity within biomass thermal power stations.

Tatano’s technical staff is always available to advise the most suitable solutions to meet customers’ needs.

      through the modulating power regulation and the integration of a thermal storage system it is possible to maximize the number of hours of operation at full load of the boiler, with a reduction in operating costs and CO2, thanks to an efficient use of the resources.

Low-NOx technology: warmth and respect for the environment

Wood chips boiler boasts an advanced 3-stage combustion technology that that combines the advantages of the underfed auger burner with those of the mobile grate; it is therefore possible to use various types of cheap and non-pre-dried fuel, such as industrial wood chips, bark and remains of pruning.

Mobile flat or step grate fuel combustion systems are made in low NOx version and are equipped with a combustion chamber capable of operating primary, secondary and tertiary air subdivision, reducing emissions.

The separate regulation of combustion air takes place automatically by inverter together with the regulation system of the residual oxygen content (Lambda probe), ensuring high eficiency, lower fuel consumption and reduced emission values, even at partial load.

Moreover, this process is made more effective thanks to the activation of an exhaust gas recirculation system (available as an accessory). A feed auger carries the fuel into precombustion chamber where it pre-dried and then transferred to the grate, divided into sections with two primary ventilation zones.

The material is moved slowly through the continuous movements of the mobile grate operated with hydraulic system and automatically adapted to the power demand.

The grid has high resistance to wear thanks to the trolley-mounted structure in chromed steel and cast iron elements that can be replaced individually for minimum operating costs and ease of maintenance.

The refractory cement vault above the grid ensures a high combustion temperature even in the presence of wet fuel. The secondary and tertiary air that flows into the post-combustion chamber allows a gradual and complete combustion.
The boiler body and the heat exchanger are fully covered with water to maximize heat exchange and reduce temperature of the external surface with minimal dispersion.

The combustion ashes are removed and transported automatically in separate containers with the possibility of centralized extraction on an external tank by auger or rakes; moreover, under the grate it is possible to install an ash removal device (on request).

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.
