Development of optimized fuels from new sources of Biomass and test of new technological solutions are the key to future increase in solid biofuels and further reduction of CO2 emmission.
On March 18th 2010 ANDRITZ FEED & BIOFUEL and The Danish Technologi¬cal Institute hosted the opening reception for the biomass pretreatment and pelletiz¬ing test plant in Sdr. Stenderup near Kold¬ing, Denmark. Through a close cooperation between the two partners, the plant is now a flexible test facility for full scale trials of milling and biomass pelleting. The plant in¬cludes an industrial scale biomass pelleting line with hammermills and cooler dedicated to the test and analysis processes in a bio¬fuel pellet production. The event celebrated the opening of the plant and introduced the more than 150 visiting delegates to the pos¬sibilities for full scale biomass processing tests.
As it is meant to handle all sorts of biomass the plant is by no means a standard setup. The chute with mechanical transport is de¬signed to handle biomass in a more mas¬sive form like wood chips, saw dust, dried beet pulp, and other types of granulated ma¬terials. The air transport intake is suited for loose long fibered materials like straw, co¬conut coir fibres, elephant grass and numer¬ous other types.
Later this spring ANDRITZ FEED & BIO¬FUEL will install a straw shredder. This will enable the handling of all types of biomass which are normally compacted in bales.
The plant is equipped with two hammermills, an Optimill 500 for coarse grinding and a Multimill 450 for fine grinding.
From these facilities ANDRITZ FEED & BIO¬FUEL and The Danish Technological Insti¬tute offer all relevant tests of pretreatments, milling and pelleting of biomass fuel process¬ing including relevant analysis.
The pelleting section is equipped with two conditioners, one with traditional paddles for normal conditioning and one with a screw to ensure controlled retention time. This pro¬vides the ability to operate at various con¬ditions and to see whether or not retention time does affect the pelleting performance. ANDRITZ FEED & BIOFUEL and The Dan¬ish Technological Institute can also optimize added steam and starch addition if that is a part of the test.
