Opis:: Electromagnetic method of registration of partical velocity profile U(t) has been used for investigation of nitromethane/methanol mixtures of different concentration including mixtures in which weigh ratio is close to the detonation limits concentration. In all mixtures in the experimental records of U(t) a typical spike was registered, this enables to locate the Chapman-Jouguet state, and to determine a set of detonation parameters including the pressure PC-J data which are necessary for finding of true detonation limits on concentration according to methods proposed by Dremin recently. Attention was given to some disagreements with one-dimensional ZND detonation theory.

Opis:: This paper describes flammability measurements and data on the missile fuel, JP-10. The measurements include maximum explosion pressure, maximum rate of pressure rise and limiting flammability concentrations. Through a series experiments, the influences of the concentration of gaseous JP-10 in air on the explosion pressure and on the rate of explosion pressure rise have been analyzed, and the results are discussed. The explosion pressure of gaseous JP-10/air mixtures reached their highest values within the studied range at a concentration of 1.88%. The variation trends in the explosion pressure and the rate of pressure rise of gaseous JP-10/air mixtures with volume % appear similar. When the volume % of gaseous JP-10 lies in the range 0.5-1.8%, the explosion pressure and the rate of pressure rise for gaseous JP-10/air mixtures increase with the volume %, while in the range 1.8-5% these parameters decrease with the volume %. The flammability limits of gaseous JP-10/air mixtures are near those of gaseous n-decane/air mixtures. However, the maximum explosion pressure and the maximum rate of pressure rise of gaseous JP-10/air mixtures are much higher than those of gaseous n-decane/air mixtures.

Opis:: Fire and explosion prevention plays an important role in the running of chemical processes, especially where flammable gases or liquids are present, which may form explosive atmospheres of gas/vapours in air. These include organic solvents such as the hydrocarbons C6 - C8. It is necessary to know the properties of these substances and the volume of an explosive atmosphere. Determination of these can identify and assess the risk of explosion, and zones in areas where there are or may occur explosive atmospheres. Information on explosion limits are also important in safety data sheets. In this study a research methodology is compared with previous studies and signals guidelines for explosion protection and prevention of explosions. The aim of this work was to determine the experimental explosion characteristics like LEL, UEL, pmax and (dp/dt)max for selected hydrocarbons. The investigations were carried out in accordance with EN 1839 by method b and EN 15967. The studies were conducted in a closed, spherical, acid-proof vessel of 20 dm3 internal volume
