MECHANISMS OF FIRE SUPPRESSION OF PETROLEUM PRODUCTS IN TANKS BY UNDERLAYER MANNER UNDER CONDITIONS OF ACTIVE FLOW

There the main mechanisms of flame suppression of petroleum products in tanks under the conditions of active opposing flow, of fuel and advent of "surf", of absorption of foam part by the fluid flows from the combustion surface have been determined on the basis of experimental and theoretical study for the first time. The model of flame suppression process in tanks by the sublayer manner has been developed. The determination procedure of optimum quantity of foam heads, the main requirements for the system of sublayer suppression have been developed. The results have been used in development of Federal Purpose Program "Fire Prevention and Social Protection in 1995 - 1997", in design of sublayer suppression systems at the Yaroslavl and Novokuibyshevsk Oil-Refining Works, have been included as the components of Building Cpde 2.11.03-93 "Storehouses of Oil and Petroleum Products.
