USE OF METHODS OF SIMULTANEOUS THERMAL ANALYSIS FOR RESEARCH OF COAL IN PRODUCTION OF FIRE-TECHNICAL EXAMINATION

Furnace heating — view local heating, in which the premises are heated installed heating furnaces. Thanks to the simplicity of the device and the possibility of using various types of local fuel, furnace heating widespread in different countries and used for centuries. In recent years, with increasing areas of building of low-rise buildings and garages increases the number of used heating installations of various kinds. In recent years, with increasing areas of building of low-rise buildings and garages increases the number of used heating installations of various kinds. Practice of research fires shows that the most frequent violations that led to the occurrence of fires, are heated to a high temperature surfaces of furnaces, furnace doors and location of the combustible materials in the immediate vicinity. To the most widespread in Russia fuels for heating furnace include wood, coal, charcoal, and coal. After the fire and intensive thermal influence select undamaged objects is possible only in trace. In forensic science center of Ministry of internal Affairs of Russia has carried out research to assess the possibility of applying the methods of thermal analysis for the study of small amount of coal taken from the scene of a fire heating stoves. Studies have been conducted samples of wood and coal by method of simultaneous thermal analysis (instrument SDT Q-600) for their differentiation. The results allow to evaluate the heat of combustion of fuel samples to estimate the load on the material furnaces in production of fire-technical examination.
