Designed and built for the use of biomass. The supporting structure has a horizontal design and is built with sturdy steel sheets which can resist to thermal stresses and high pressures thrust thanks to tensile bars.
The wet walled large-volume combustion chamber is fitted with side entrances for the distribution of combustion air, and with an openable door for the manual loading of large size fuel and for the periodic cleaning of the grate.
The whole combustion chamber is lined with high-quality refractory bricks rich in alumina content (65%) to achieve a high temperature (between 800 and 1200° C), thus optimizing the combustion.
The smoke circuits horizontal heat exchanger is made with sturdy steel tubes immersed in water and their geometry ensures the best thermal exchange and performance.

The burner is mechanical with a screw conveyor and is equipped with a gearmotor to adjust the flow.
