“…Rice husk (RH) and rice straw (RS) were used as the starting materials, because the global amount of residues from rice crops (Oryza sativa L.) is 0.9 Gt per year, i.e., 25 % of the total amount of the global agricultural residues (Knoblauch et al, 2011). Pruning woodchips of apple tree (AB) (Malus pumila) was also used as a biochar material because its carbonization is considered as an alternative waste management for the reduction of hazardous materials such as pesticide remnant (Suri and Horio, 2010). Although several studies have been recently proposed the use of biochar derived from orchard prune residues as a soil amendment (Fellet et al, 2011;Alburquerque et al, 2013), reports on the evaluation of the pyrolysis process on this feedstock are scarce.…”

Abstract. Biochar is widely recognized as an efficient tool for carbon sequestration and soil fertility. The understanding of its chemical and physical properties, which are strongly related to the type of the initial material used and pyrolysis conditions, is crucial to identify the most suitable application of biochar in soil. A selection of organic wastes with different characteristics (e.g., rice husk (RH), rice straw (RS), wood chips of apple tree (Malus pumila) (AB), and oak tree (Quercus serrata) (OB)) were pyrolyzed at different temperatures (400, 500, 600, 700, and 800 °C) in order to optimize the physicochemical properties of biochar as a soil amendment. Low-temperature pyrolysis produced high biochar yields; in contrast, high-temperature pyrolysis led to biochars with a high C content, large surface area, and high adsorption characteristics. Biochar obtained at 600 °C leads to a high recalcitrant character, whereas that obtained at 400 °C retains volatile and easily labile compounds. The biochar obtained from rice materials (RH and RS) showed a high yield and unique chemical properties because of the incorporation of silica elements into its chemical structure. The biochar obtained from wood materials (AB and OB) showed high carbon content and a high absorption character.

Biomass as fuel is used for many years. At present it is important to effectively use energy sources because price of energy is more and more expensive. This is the main reason for building of modern low-energy houses. The projected thermal performance of these buildings rarely exceeds 4-6 kW. During most days of heating season these buildings need only 2-4 kW of heat but almost all produced heat sources have nominal thermal power higher than 10-15 kW. Because of this the thermal power of majority heat sources is oversized and using of them could be complicated. One of the solutions of this problem should be heat storage in accumulation vessels. The paper deals about using of local heat source with warm-water heat exchanger for combustion of wood biomass. There were tested thermal and emissions parameters of wood stoves. There was measured thermal power to air and to the accumulation vessels, production of carbon monoxide (CO), production of nitrogen oxides (NOx) and production of particulate matters (PM). The results shows that local heat sources with warm-water heat exchanger for combustion of wood biomass could be used for heating of new low-energy buildings.

Some types of biomass have a high content of alkali oxides and salts and, thanks to it they feature a low ash melting temperature which may result in various combustion problems. Slag and sintered particles that are formed prevent the fuel from being supplied, restrict the access of combustion air, heat transfer in the heat exchanger and can cause corrosions. One possibility of increasing the ash melting temperature is to add additives. Some additives can change chemical composition of fuel ash, thus changing also the ash melting temperature. The paper deals with the adding of 2 % additiveskaolin, talc, lime, limestone, dolomite, bentonite to silver grass. The tested additives increased the ash content but they also changed its chemical composition, which resulted in the increase of the ash melting temperature. Best positive results were achieved with kaolin a nd lime which increased the ash melting temperature by approx. 300 °C.
