Mathematical modeling of thermal fire effect on tanks with oil products

Abstract

The aim of the work is the development of mathematical models for research that allows to determine the ultimate indicators of the thermal effect on tanks with oil products in a fire. A calculation method was developed to implement the calculation for various scenarios for the development of a fire in a tank with oil. After the calculations, the results of mathematical modeling of the temperature on the walls of the reservoir in the conditions of a fire in neighboring reservoirs in the form of temperature distributions were obtained. Analysis of the temperature distributions showed that the most dangerous scenario is when the fire occurs according to scheme No. 3 in the case of burning an oil torch at a temperature of 1500 K. In each case, the maximum temperature of heating the tank wall is almost unaffected by the oil, which is confirmed by the curves of the maximum temperature curves heating of the reservoir wall, depending on the time of fire impact on adjacent tanks. The maximum temperature of the reservoir wall was determined at the place of its connection with the oil product, it is preserved.

“…On the other hand, the energy balances around the TK-100, which is related to T3 and the heating coil, which is also related to Ts are presented in (2) and ( 3) respectively. It should be noted that for deriving the energy balance related to the TK-100, it is assumed that the volume of the liquid in the tank is fairly constant, for a given operating height, i.e., the level control LIC-102 operates properly.…”

“…It is interesting to note that there are not many works that address these two control goals, in fact, in most of them, they cover the temperature control as the main one, leaving in second place, the level of the tank, assuming steady state conditions regarding the level [1][2][3][4][5].…”

Technical Implementation of the Concept of Using Gel-Forming Systems to Protect Tanks with Oil Products from Thermal Effects of a Fire

“…The general principle in eliminating fires in tank farms and on the railway is to protect the equipment and walls of neighboring tanks from thermal emission [16,17]. Existing methods of protecting tanks from thermal emission are analyzed in [18]. It is concluded that all the methods used have common disadvantages that are characteristic of water.…”

Investigation of the use of the acoustic effect in extinguishing fires of oil and petroleum products

“…Obviously, the most effective way to minimize the effects of the ignition of petroleum products is to prevent it. For this purpose, the situation is modeled [7,8], the use of early response sensors [9,10] and fire-extinguishing systems [11] are used. In cases where the fire occurs, various fire extinguishing means are used [12,13].…”
