High-power intense heat exchange devices found wide circulation in the world industry. One of types of such heat exchange devices are the furnaces of fire heating which are widely used in oil processing and chemical branch. Because of considerable heterogeneity of temperatures in their combustion chamber, there is an overheating of a part of pipes, which is followed by the increased coke production on the surfaces of heat exchange contacting to oil products. And, as a result, reliability of operation of the equipment, its resource of work and efficiency of oil processing decreases. In work the design of heat exchange pipe of the furnace fire heating with use the eutectic alloy of lead with bismuth is offered. The design represents the "pipe in a pipe" heat exchanger which ring gap is filled with the eutectic alloy of lead with bismuth, fire heating is carried out from an external surface, oil products settle down in an internal pipe. With use of numerical modeling in an OpenFOAM CFD package comparative estimates of distribution of temperatures on the heat exchange surface contacting to oil products for a "traditional" heat exchange pipe and a design of the pipe offered by authors in the conditions of uneven fire heating from an external surface are carried out, results of calculations are presented. It is shown that the pipe design offered by authors promotes alignment of temperature fields on the section of heat exchange pipe.
