Prediction of fire origin location to wood materials charring ; Gaisro kilimo vietos nustatymas pagal medinių konstrukcijų apanglėjimą
Most countries for constructing low-rise buildings apply mostly wood in manufacturing of various structures (bearing structures of roofs, walls, beams, columns and etc.). In cases of fire these buildings manifest mostly such evidences of burning which are called charring of wooden parts (structural elements). For investigators of fire it is relevant to find the connection of this feature with certain significant effects of fire, namely its duration or temperature, in order to be able to determine the exact location of the fire start (spot/source) as well as the cause of initiation (reason). The dynamics of fire aggravates the determining of accuracy of determining the duration of wood burning, because in wooden structures there are enacted many additional physical-chemical processes. These processes make a great influence on fire resistance of structures, on the influence of the knowledge on different fields. Well known professionals consider that the attention to charring rate under the analysis of fire is paid a too narrow one and played as inadequately considerable role. In our country there have been so far applied the remarks and recommendations of Russian scientists, regarding charring rates, there are presented generalized charring rates of wood, the particularity of coal layer measurements is discussed, the calculation of burning duration taking into account theoretical and instrumental methods , however without mentioning the influence of majority of factors, relevant for today.The task of the work is to exhibit the way the justified and precisely analyzed various cases of charring a well as appropriate detailed investigation of charring processes and measurements are possible to be applied for finding out the location of fire origin. It is useful to perfect the technique for determining the place of fire origin in order to achieve that task. It is intended for the new method to be able to allow more accurately to determine the influence of fire on wooden structures from the point of view of temperature and duration, as well as it could simplify the process of carrying out the main goal of research on fire, namely to detect the exact place of fire start and the reasons of fire outbreak.
