Abstract

Currently mist water is one of the most promising areas of fire protection. We performed an experimental study of phase transformations drops of water mist (range 50 - 500 microns) in motion in a high-temperature (500 - 2000 K) typical products of combustion of petroleum products (gasoline, kerosene, acetone, alcohol). We used high speed (the speed of shooting at least 105 frames per second) and optical methods of recording streams of liquid and gas medium. We determined the effect of the parameters of the test process (the initial temperature and the initial droplet size) at the rate of evaporation of atomized water under these conditions.

Highlights

Objects of oil and gas industry are an important part of the fuel and energy complex of Russia The country has an extensive network of main oil pipelines, oil pipelines and gas pipelines

The results showed the intensity of the process of evaporation of water spray greatly influenced by the initial size and the temperature of the water mist

Summary

Introduction

Objects of oil and gas industry are an important part of the fuel and energy complex of Russia The country has an extensive network of main oil pipelines, oil pipelines and gas pipelines. It passes through the territory of the majority of the Russian Federation subjects. Danger explosive situations constitute a large amount of combustible liquids under pressure on objects of the oil and gas industry. Liquids can spill on areas and burn over large areas at infringement of equipment. For a special danger in this case are oil products, which are located high in the areas near rivers, reservoirs, railways, roads and other communications. One of the ways that provide the prevention of emergencies is to equip the production facilities with modern fire protection systems [1]
