Ash melting temperature in biomass fuels is lower, as compared to the fossil fuels. The study was conducted with an aim to evaluate a variety of factors (agro-meteorological conditions, chemical composition of straw and shives, nitrogen fertilizer rates) influencing the ash melting temperature. The objects of the research are linseed and hemp. The plants used within the research were grown in humi-podzolic gley soil, and afterwards, during the time period 2008-2010, the acquired samples were tested in the Agricultural Science Centre of Latgale (Latvia) and Upyte Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry (Lithuania). The following parameters were studied: 1) chemical composition of straw and shives (ISO 11466, ISO 625, ISO 333, ISO 334); 2) ash melting characteristics in oxidizing atmosphere (ISO 540); 3) yield (ISO 6496); 4) and ash content (ISO 1171 – 81). The ash melting temperature of hemp dry matter was lower than 1000 ºC. The research indicated some ash melting anomalies – sublimation (in 2009). As compared to 2010, the ash content in 2009 was 2.0-3.0 times higher, and the amount of alkali and alkaline elements also was higher.
