Design and Modernization of Circuit for Fuel Oil Heating and Tar Cooling

Abstract

AbstractThe solution to the scientific and practical problem of the modernization of the fuel oil heating department was proposed. The modernization provides two main tasks solutions: maximum heat recovery and existing equipment in the new technological scheme. The limitation of the hardware implementation is the clause of two cross-flow heat exchangers of the Compabloc type presence and two spiral heat exchangers with given surfaces of heat transfer areas. The study’s primary goal is to achieve the assigned task of heating fuel oil by using the existing heat exchange equipment and redistributing the flows. In this case, the flow rates, temperatures, and pressure losses indicated in the formulation of the problem are rigidly fixed, but the possibility of installing additional heat exchange equipment is allowed. The original requirement for recuperative heating with the available apparatuses was not feasible. A new scheme of the heating department with an additional spiral heat exchanger installation was proposed to accomplish this task.
