The dreadful accidents at Three-Mail Island and the Chernobyl nuclear power plant gave a powerful incentive to investigate combustion and concentration limits of flame propagation in hydrogenous mixtures with high steam content at high temperatures and pressures. Analysis of results obtained during large–scale experiments has revealed the fact that the concentration limits of the fast combustion regimes, the deflagration-to-detonation transition and the detonation limits broaden towards leaner mixtures. However, the combustion concentration limit values obtained in laboratory-like environments are also of use.
