A Modular Test Bench for Explosion Detection Systems

Requirements on fire and explosion detection systems continue to rise, especially in safety-sensitive areas. This paper presents a test bench for explosion detection systems. Theoretical computations of the flame temperature as a function of fuel/air ratio and maximum occurring combustion pressure specify the boundary conditions. Additionally, a series of experiments is performed to validate the theoretical results and to characterize the generated deflagrations. Due to its modular construction the test bench is able to create hydrocarbon-based deflagrations of adjustable scale. A high safety standard is guaranteed by filling the fuel and enabling the ignition device in separated steps
