ABSTRACT

This paper deals with the research of fire risk and energetic potential of agro-pellets. Agro-pellets made from a mixture of hay and straw of cereals and oil plants, pressed at 80 to 150 MPa at 100 ° C, and the initial water content from 8 to 16 wt% were subjected to research. Fire risk and energetic potential were examined on a cone calorimeter by test procedures according to ISO 5660-1: 2015, using two densities of heat flux (25 and 50 kW/m2). Orientation of samples was horizontal. The samples were dried before testing to the water content of 0 wt% at 103 ± 2 °C. Fire risk and energetic potential were evaluated based on the heat release rate (HRR), maximum heat release rate (mHRR), maximum average rate of heat emission (MARHE), total heat release (THR), carbon monoxide yield, smoke yield and effective heat of combustion (EHC). Maximum heat release rate measured at heat flux densities of 25 and 50 kW/m2 was 335 and 459 kW/m2. Maximum average rate of heat emission measured at heat flux densities of 25 and 50 kW/m2 was 171 and 272 kW/m2. Total heat release measured at heat flux densities of 25 and 50 kW/m2 was 124 and 101 MJ/m2. Carbon monoxide yield (related to sample mass loss) measured at heat flux densities of 25 and 50 kW/m2 was 87.60 and 129.33 g/kg. Carbon monoxide yield (related to heat released) measured at heat flux densities of 25 and 50 kW/m2 was 4.45 and 7.73 g/MJ. Smoke yield (related to sample mass loss) measured at heat flux densities of 25 and 50 kW/m2 was 3814 and 4593 m2/(m2s). Smoke yield (related to heat released) measured at heat flux densities of 25 and 50 kW/m2 was 194 and 275 m2/MJ. Effective heat of combustion measured at heat flux densities of 25 and 50 kW/m2 was 19.70 and 16.72 MJ/kg. The obtained data show that maximum heat release rate, maximum average rate of heat emission, carbon monoxide yield and smoke yield increase with increasing heat flux density. On the contrary, total heat release and effective heat of combustion decreases with increasing heat flow density.
