PROCESSING EQUIPMENT

With an energy content of approx. 7500 BTU (British Thermal Unit) per pound, this fuel is higher (in energy) than Lignite coal.

The “bio-cubes” have an average density of 30 pounds per cubic foot and a moisture content of 8-10%.

Biomass fuel cube “bio-cube” is designed to replace the use of Coal, Propane and Natural Gas in certain applications.

OUR PRODUCT

PBE is constantly investigating new biomass based materials that could be used as a solid fuel.

Various feed stocks are presently being evaluated including: Wheat, Flax, Hemp, and Canola straws.

STOKER DESIGN FEATURES

Stoker basic features:

Sufficient height for maximum combustion volume

Hi temperature insulation and refractory

Combustion and over-fire air system

Automated ash removal

Chain-grate design

CHAIN GRATE DESIGN FEATURES

ADVANTAGES

The system provides a large grate area to assure a complete combustion of the solid fuel. (i.e. a 100 BHP stoker has 10FT^2 of grate area)

Moving grate, made of cast iron links, eliminates clinkers formation

Combination of air passing through the fuel bed (combustion air) and over-fire air (secondary air) provides turbulence required for rapid and complete combustion of any solid fuel.
