Critical Rate of Thermal Decomposition of Pure and Impregnated Lignocellulosic Materials

Contribution deals with monitoring the impact of airflow velocity around the sample, the oven temperature during thermal decomposition and nature of the sample for the minimum mass flux rate needed to initiate flame combustion. We used the samples of lignocellulosic materials, particularly spruce wood, pure cellulose, flax, cellulose impregnated by 5%, 10%, 15% water solution of KHCO₃ and by 5%, 10%, 15% water solution of (NH₄)₂HPO₄.
