Abstract

As is well known, hydrogen exhibits a wide flammability range, low ignition energy, and high diffusivity, which create significant explosion risks in storage and handling facilities. Therefore, the development of effective methods and devices for the detection and control of hydrogen explosions is essential to ensure operational safety. This paper presents the development and experimental validation of an explosion control device intended for hydrogen storage systems. The proposed device is based on an optical ultraviolet sensing principle that allows rapid detection of combustion phenomena associated with hydrogen ignition. The system is designed to identify the optical signature of the spark at the early stages of combustion and to initiate a control response aimed at limiting the propagation of the explosion. The experimental device integrates an optical sensor, a signal processing module, and a control mechanism. To evaluate its performance, the device is tested in a controlled experimental stand specifically designed for hydrogen explosion studies. The experimental results demonstrate that the proposed device is capable of rapidly detecting hydrogen combustion and providing a reliable control response. Furthermore, it can be used in a vast area of applications such as: fire detection in large-scale facilities, fire detection in warehouses, discharge detection of manufacturing process, arson detection, hydrogen flame detection, discharge detection of transformer plant and power distribution panel, fire detection in vehicles and aircraft.
