METHOD FOR EXPLOSION PROTECTION IN OPERATING SYSTEMS FOR TRANSPORTATION OF GASES

摘要

A method for explosion protection in operating the systems for transportation of gases and dust and gas mixtures includes the flame arrester containing the stationary layer of the catalyst. The ratio of the gas flow in the flame-arresting element under the normal conditions to the rate of the thermal distribution of the area of catalytic oxidation is restricted. The technique provides for the use of the packing of the conductive catalyst. The electric current is passed through the packing in the case of the flame. In the process of fire-extinguishing the current is switched off.
