Abstract

The activity of evaluation and verification of industrial ventilation installations has a strong preventive role in terms of explosion risk mainly due to the fact that of the three determining elements that can lead to an explosion phenomenon, ventilation installations can determine the presence of two elements namely the presence of fuel (gases, vapours, dusts, mists) and the source of initiation (hot surface, flame, sparks of mechanical origin, electrical sparks, static electricity, etc.). The development of experimental systems on„ which particular hazardous aspects that may occur during the operation of industrial ventilation systems can be studied are vital to avoid dangerous situations in the current operation of ventilation installations. Knowledge of the dynamics of formation of explosive / toxic / asphyxiating environments is achieved by analysing explosive mixtures in relation to specific explosive intervals and is one of the most important priorities in ensuring optimal health and safety at work in industrial activities. The information obtained by analysing the dynamics of the formation of explosive / toxic / asphyxiating atmospheres is extremely useful for personnel responsible for health and safety at work, because with their help relevant decisions can be made to ensure safety and health conditions at the level of industrial premises. The paper presents an experimental equipment usable for the study of industrial ventilation systems.

Highlights

Industrial ventilation is an extremely complex field (Goodfellow H., Tahti E., 2001, Biegert B., Railio J.,2001), that requires deep knowledge of fluid dynamics in the modern computerized version (CFD), three-dimensional heat propagation, complex fluid flow, equilibrium and transient conditions, operating problems, contaminants inside and outside the enclosure, etc.Industrial ventilation systems are based on execution projects that include systems to prevent and combat risk factors that may occur during the expected technological processes (Cioclea D., Lupu C., Gherghe I., 2013)
In order to analyse the behavior of ventilation systems in normal operation or overload, as well as to identify how to sweep the functional parameters related to fans, research is required in the laboratory and in the field in order to prevent the risk of explosion
This paper has highlighted the following findings: 1. The development of experimental systems on which particular aspects can be studied that may occur during the operation of industrial ventilation installations, are useful to avoid dangerous situations in their current operation; 2

Summary

Introduction

Industrial ventilation systems are based on execution projects that include systems to prevent and combat risk factors that may occur during the expected technological processes (Cioclea D., Lupu C., Gherghe I., 2013). In order to avoid the risk of the formation of potentially explosive and/or toxic atmospheres, it is necessary both the development of the experimental capacities and the periodic evaluation and verification of the industrial ventilation installations.
