“…The differences in the chemical composition of ash biomass could be caused by agricultural operations. A plausible hypothesis is that on-field shredding with the forage harvester produced a loss of biomass material such as leaves, which are known to contain higher nutrient amounts (Fournela et al, 2015;Prohnow et al, 2009). Theis et al (2006) conducted a comparison of the straw, peat, and bark ash deposition behaviours with different chemical compositions.…”

As a fuel, biomass differs in its properties from fossil fuels and acquisition thereof for energy purposes is limited; hence, the ongoing search for new bioenergetically useful plants. The article presents the results of physical and chemical analyses of seven species of perennial grasses: tall wheatgrass, tall wheatgrass ‘Bamar’, brome grass, tall fescue ecotype, reed canary grass, giant miscanthus, and sorghum. The research involved technical and elemental analysis as well as analysis of the ash composition performed in order to determine their potential use for combustion process. The measurement results were compared with those obtained for hard coal and agricultural biomass, which is widely used in the energy industry. The results suggest that perennial grasses can successfully be combusted with similar performance to coal if burned in appropriate combustion installations.

“…They provide high-quality feed thanks to high and stable fodder and seed productivity, longevity and winter hardiness. Perennial grasses are essential in protecting soils from water and wind erosion [1,2,3]. A significant reserve for increasing fodder supply is expanding the range of forage plants, replacing low-yielding species with more productive ones of enhanced nutritive values adapted to the soil and climatic conditions of cultivation [3,4].…”

Realizing productive capacity of crested wheatgrass varieties in the southern forest-steppe of the Bashkortostan Republic

Crested wheatgrass being high drought-resistant, is a promising forage crop for the Republic of Bashkortostan. It is relevant in developing varieties adapted to the environmental stress factors that have productive longevity, increased seed and fodder productivity. The paper presents the research results of crested wheatgrass varieties conducted in the nursery of competitive variety testing for seed productivity in 2018-2020. High seed productivity due to well-developed tillering capacity, powerful heads and large seeds of cultivars like Batyr, Brodskii crested, Parkway indicate their adaptation to local conditions and make them promising varieties for further study.

“…The PM sampling line included a stainless steel nozzle (12.5 mm in diameter), a stainless steel probe (600 mm long), an S-type Pitot tube, a 75-mm glass fibre filter (Whatman 934-AH, GE Healthcare, Mississauga, ON, Canada) inserted into a Pyrex filter holder installed in a heated compartment maintained at 120 °C, four impingers connected in series in an ice bath, a metering system (XC-563 Digital Meter Console, Apex Instruments, Fuquay-Varina, NC, USA) and a vacuum pump. More details on PM sampling method are given here [42].…”

Effect of Additives and Fuel Blending on Emissions and Ash-Related Problems from Small-Scale Combustion of Reed Canary Grass

et al. 2015

Agricultural producers are interested in using biomass available on farms to substitute fossil fuels for heat production. However, energy crops like reed canary grass contain high nitrogen (N), sulfur (S), potassium (K) and other ash-forming elements which lead to increased emissions of gases and particulate matter (PM) and ash-related operational problems (e.g., melting) during combustion. To address these problematic behaviors, reed canary grass was blended with wood (50 wt%) and fuel additives (3 wt%) such as aluminum silicates (sewage sludge), calcium (limestone) and sulfur (lignosulfonate) based additives. When burned in a top-feed pellet boiler (29 kW), the four blends resulted in a 17%-29% decrease of PM concentrations compared to pure reed canary grass probably because of a reduction of K release to flue gas. Nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions varied according to fuel N and S contents. This explains the lower NOx and SO2 levels obtained with wood based products and the higher SO2 generation with the grass/lignosulfonate blend. The proportion of clinkers found in combustion ash was greatly lessened (27%-98%) with the use of additives, except for lignosulfonate. The positive effects of some additives may allow agricultural fuels to become viable alternatives. OPEN ACCESSAgriculture 2015, 5 562
