EARLY STAGE DETECTION OF COAL SPONTANEOUS COMBUSTION IN VIEW OF PRETREATMENT OF THE COAL
Original language description
Two samples of bituminous coal were studied to describe changes in evolution of the gases indicating early stage of spontaneous combustion process. Three types of coal pre-teatment procedures were used to simulate in situ conditions of the coal lying near the ?spon-com? site in the sealed off area: i) pre-oxidation of coal (200, 250°C), ii) pre-heating of the coal under inert gas (200, 250°C), and iii) extinguishing of pre-heated coal (200, 250°C) by liquid water. After the pretreatments, amount and composition of gases evolved from the coal during aerial oxidation at temperatures 40 - 200°C were measured at continuous flow reactor. Irrespective of type of the pre-treatment, oxidation of the pre-treated coal was found to be accompanied by increased COevolution in comparison with not-treated coal (up to temperature 100°C).
