Investigations on the Behavior of Liquefied Fuel Gases Escaping into the Open Atmosphere. Part 1. Introduction, Test Conditions, Testing Installation, Experiments with Gaseous Propane

摘要

In order to determine the behavior of LPG escaping into the open air, experiments with gaseous and liquid propane and butane were made. From many possible test conditions, the following parameters, considered as important were selected and varied: the escaping quantity, the wind velocity, flow into wind direction, against wind direction and by 90 exp 0 to the wind, propane and butane, escaping as gas and as liquid. In Part I of the investigation, the experiments with gaseous propane are described. Measurements of single concentrations were carried out in the middle-plane of the gas flow and in the total field of distribution. For comparison, ignition tests with a torch were made. The measurements of concentration and the ignition tests show that the maximum ignition distance of an escaping quantity between 200 and 300 kg/h of gaseous propane lies between 2 and 3 m from the leak.
