Development of Efficient Aerosol-Based Fire Suppression Systems for Special Hazards

The effectiveness of aerosol-based fire suppression systems is influenced by several critical factors, especially when integrating them into environments with special hazards like rail locomotive & coaches, data centre, battery & transformer room, aircraft, armoured vehicle engine compartment .This research emphasizes optimizing aerosol particle characteristics and system parameters to enhance fire suppression performance while minimizing operational and safety risks.A major focus is on the diffusion coefficient(D), which dictates particle dispersion efficiency, fast spreadability and is improved by reducing particle size to achieve better coverage and uniformity.The selection of an appropriate coolant is equally vital, as aerosol generation involves high thermal outputs ranging from 600C to 1200C, requiring effective heat-absorbing materials to reduce the risk of thermal damage.Porosity of coolant is another crucial factor since improper design may lead to nozzle clogging and system malfunction.Furthermore, the chemical composition of aerosol agents may pose corrosive risks to sensitive electronic and control systems.Visibility impairment caused by suspended aerosol particulates and potential health impacts from prolonged exposure are also significant concerns.In addition, the accidental discharge of aerosol suppression systems-whether triggered by thermal activation during installation, electrical faults, or due to inadvertent human activation represents a critical safety concern, posing severe risks to human health and life.This paper presents an integrated design strategy to overcome these limitations and offers a safer, highly efficient, and reliable fire suppression solution tailored for special hazards.
