Today, due to the rapid development of the hydrogen power industry, fire safety of hydrogen-containing facilities becomes a matter of great importance. Risk assessment for the hydrogen power facilities is one of the key objectives of the development. To find the solution, the information on the intensity of hydrogen flare radiation must be obtained. At the same time, such information published in literary sources is often incomplete and sometimes even contradictory. Therefore, the study aims to review the literary sources published in Russian and international journals.
The basic value required to assess fire hazard is the intensity of the surface radiation of hydrogen flame. The study considered four types of the flame; i.e., the gaseous jet flame, the jet flame of liquid hydrogen, the flame in the liquid hydrogen pool, and the fireball. Remarkably, the intensity of the surface thermal radiation of hydrogen flame is significantly lower when compared with the hydrocarbon flame. For fire hazard calculations, the intensity of the surface thermal radiation of jet flame of gaseous hydrogen can be adopted as equal to 33 kW/m2. The surface thermal radiation intensity value for the hydrogen fireball can be adopted as equal to 330 kW/m2. The intensity of the surface thermal radiation at liquid hydrogen combustion (for both jet flame and pool fire) can be adopted as equal to 80 kW/m2.
