  BONO SistemiBONO Sistemi, summarizing the experiences developed by the individual companies of Cannon Group in developing their own plant design, engineering and construction technologies over the years, is currently active in energy & ecology projects as well as in plastics industry production plants, chemicals blending and storage systems. To get more information please expand the product block by pressing on image or product title. To get detailed information about specific product you can download Technical datasheet file by clicking corresponding link. Biomass TypesThe BONO Sistemi biomass fuelled plant is the heart of an energy system able to generate pure heat for industrial processes, district heating for small and medium communities, and electrical power if coupled to power generators such as steam engines and turbines, or other devices. CHP Plant |  | | When the two purposes are jointed we then talk about CHP plant (Combined Heat and Power plants). Thanks to consolidated experience in the energy field BONO Sistemi engineering is able to study and design full turn-key plants starting from the greenfield. |
Here below you can see some Biomass example indicating their energy content and the equivalent electric power generated through a steam or an organic Rankine cycle. | Type | Low Heating Value | Electrical Power Equipment | Bark - 50% moisture | 2 Kw/Kg | 400 kWe/t | Chipped Wood - 30% moisture | 2,7 Kw/Kg | 550 kWe/t | Olive Husk | 4 Kw/Kg | 800 kWe/t | Grape Residues-High moisture content | 2,3 Kw/Kg | 470 kWe/t | Sorghum | 3,8 Kw/Kg | 770 kWe/t | Rice Husk | 3,6 Kw/Kg | 775 kWe/t |

Water TubeBONO water tube steam generator configuration allows to achieve these important results: high efficiency (84-85%), reduced fouling, high availability (7500-7800 hours/year), simple inspection and maintenance, low thermal inertia for quicker cooling down and heating up of boiler, reduced CO and NOx emissions. BioSteam SH, BioSteam Sat |  | | Combustion chamber made of membrane water tube walls protected by a refractory liner against corrosion, erosion and severe high temperature environment. |
Highlights - Wide furnace volume for optimised combustion and low specific thermal load
- Secondary combustion air distribution and flue gas recirculation generating turbulence to ensure complete flue gas mixing and combustion efficiency
- Integrated non catalytic NOx reduction system
- Geometry of the flue gas path in the boiler is designed to reduce the speed and thus erosion and fouling phenomena on the tubes
- Convective section with evaporating section with drums, superheater, pre-heater, economiser and air pre-heater according to process characteristics
- Hoppers are placed along the boiler for ash collection

Combustion TechnologyThe Reciprocating Grate is state of the art combustion technology suitable for any kind of biomass ranging from: high moisture content one, as for dump wood waste or virgin wood, biomass mixture, dusty biomass, as for olive residues, low specific gravity ones, as for rice husk. Reciprocating Grate |  | | The biomass is processed on a "walking inclined floor", with alternative fixed and movable rows, divided in 3 or 4 zones respectively for drying, combustion and burn out of the fuel. |
The bars keep moving the biomass and assure its intimate contact with the combustion air injected underneath each zone and pre-heated for high moisture content biomass. The bars speed movement and the combustion air flow are independently programmable for each single section in order to compensate different biomass composition, to perform the proper residence time and to adequate the boiler load. Ashes are automatically removed by reciprocating action of the grate and collected at its end into a specific hopper and moved out through an automatic conveyor. Further more alternative combustion system technologies are available: - Screw burners, suitable for uniform and small size biomass up to 10mm having moisture content below 15% wt
- Blow burners, suitable for handling powder biomass
- Fixed grate, suitable for very low specific gravity biomass as for sunflower husks and rice husks
