Abstract
The aim of the present work is to substantiate and develop a methodology for automatic fire extinguishing installations full-scale fire testing.
Materials and methods. Analysis of the risks of accidents associated with a fire at small-scale LNG production and consumption sites allows us to describe the most likely scenarios for the initial stage of a fire. Based on this analysis a test rig has to be developed. It will simulate the initial stage of a fire at an object. On the testing rig, fullscale tests of automatic fire extinguishing installations are carried out and their fire extinguishing characteristics necessary for the designing of installations are determined.
Results. Full-scale fire tests were carried out to extinguish a natural gas leak with a gas-powder fire extinguishing installation. A new solution for automatic fire protection of small-scale LNG production and consumption facilities has been proposed.
Conclusion. Analysis of fires at facilities with LNG handling shows that the most possible scenario leading to a fire is the depressurization of one of the system elements with a relatively small outlet hole (from 2 to 10 mm) and an LNG flow rate of 0.3 to 1.5 l/sec. This jet combustion could be effectively suppressed at any point of the protected local volume by creating a fire extinguishing concentration of a gas-powder extinguishing agent.
