Abstract: Alternative fuels are fuels which include: biomass fuel from waste and sewage sludge. Co-firing biomass with coal is now considered as an effective and financially attractive way the use of biomass for energy production. Perhaps in the future this new technology will replace co-efficient technologies, such as gasification in combination of the gas-steam systems, and the use of gas or ethanol from biomass to value highly efficient fuel cells [1]. The use of coal and biomass mixtures can also be a threat to the safe operation of the plant, including in particular the preparation and installation of the fuel supply. Organic matter in biomass (organic fraction) is a complex mixture of fats, proteins, carbohydrates, humic material-go and fatty acids [2–4]. Self-igniting the fuel can be the result of various factors such as chemical, physical or biological agents stored inside a large amount of organic matter. Self-igniting solid fuels storage depends on many factors such as particle size, nature and type of biomass, coal, the moisture content of the fuel, the storage method and the means of ventilation [5]. In order to determine the self-ignition temperature of coal and of biomass: straw pellets and wood pellets, the method called CPT (Crossing Point Test) [18] was used. Apart from this, the  elemental composition of these biomass as well as of coal have been marked.
