Abstract
There were investigated three sorts of herbal energy plants: elephant grass (Miscanthus giganteus), sida (Sida hermaphrodita Rusby) and reed canary grass (Phalaris arundinacea). Plantations of investigated energy plants were grown in Lithuania in the experimental fields of Aleksandras Stulginskis University, and the technical means of plant preparation and usage for energy purposes were investigated. The physical-mechanical properties of chopped and milled unconventional energy plants were investigated. These properties are required to project and choose the storage and transportation equipment. In evaluating the quality of plant chopping and milling, the fractional compositions of reed canary grass, sida and elephant grass chaff as well as the mill were determined. Determined the largest mill fraction was found in the sieve with 0.5- and 0.63-mm diameter holes (from 37.6 to 46.4%). After prepared mill pressing and pellet production were determined main physical-mechanical properties of pellet: moisture content was sufficiently low and varied from 6.7 % to 9.6 %; reed canary grass pellets had the highest density-1035.1±63.9 kg m-3 DM, the lowest density was of elephant grass pellets - 653.6±67.1 kg m-3 DM. After pellets burning, there were determined the emissions of harmful gases to the environment. The highest concentration of carbon dioxide was detected when burning sida (7.9 %), and the smallest when burning elephant grass (5.2 %). The most carbon monoxide (CO) was determined when burning elephant grass (2295 ppm), and the smallest concentration of CO was observed when burning reed canary grass (905 ppm). The nitrogen oxide emissions differed only insignificantly; the values ranged from 176 ppm (Reed canary grass) to 216 ppm (Elephant grass). After energetic evaluation of the technology, the common energy preparation expenditures of granulated bio fue 1 and energetic grass were determined.
