The article considers the dynamics of flammable substances concentrations in ventilated rooms.
Ventilated rooms are used for equipment and installations where the risk of explosion is caused by the presence of flammable substances such as gases, vapours and mists. The first part presents the explosion risk associated with presence of flammable substances and the classification of atmospheres in which explosion risk is noticeable. Thus, for areas where the explosive atmosphere can be delimited inside a compartment and a classification of explosive atmosphere outside this compartment is not desirable, this compartment can be designed as a ventilated room. The second part presents the type of protection through artificially ventilated rooms, requirements of protection types and applicable tests. Thus, in order to ensure protection to explosion through ventilated rooms, these must comply with specific applicable requirements such as: minimizing the possibility of accidental or otherwise release or entry of an abnormal volume of flammable gases or vapours, the safety monitoring system must be eligible for the situation of non-functional ventilation, the air flow provided by ventilation must be sufficient to control the internal source of release. In the third part, a parameterized simulation of flammable substances concentration is performed, using theoretical models according to specific standards for area classification in case of explosive atmospheres and also pressurized equipment. As a conclusion, the indirect estimation of flammable substance release rate could be done using the dynamics of the concentration, also it can be mentioned that the value of admissible flow of flammable substance released inside ventilated rooms is dependent on available ventilation, on the lower flammability limit of flammable substances released inside, on the parameter that characterizes the number of air changes and the coefficient that qualifies the non-uniformity of distribution of the flammable substance concentration. |
