The new mechanism of burning propagation is investigated that differs from deflagration and detonation as well. The presence of sprayed water in flammable gas mixture may result in narrowing of concentration limits of usual Chapman-Jouguet detonation. Outside of these limits the usual detonation does not exist, and any initial ignition will damp. However under such conditions quite different mechanism of burning propagation may exist that allows combustion to propagate through large distances. This mechanism is associated with interphase friction and may exist in two-phase systems, where moving gas undergoes resistance force. The gas-drop suspension is the example of such a media.
