- W4205370049 abstract "In this paper, a review of the scientific and technical literature, for the analysis of plants and equipment that may be potential targets for the development of the industrial heat recovery system for an engineering plant, as well as the analysis of the magnitude of heat loss from the heated surfaces of the process equipment. Analysis of heat exchange processes during the cooling of the heated surface was carried out on the basis of equations contained in ANSYS Fluent package. The following boundary conditions have been adopted when modeling heat transfer processes: heated surface temperature of 700 - 800 °C; The coil heat exchanger is located at a height of 100 mm from the molds filled with molten metal and consists of 40 elbows with a diameter of 10 mm and a wall thickness of 1 mm. Knee length equal to 660 mm.The following conclusions can be drawn from the results: 1) The heated surface temperature rise leads to an increase in water heating zones with a high heat capacity and therefore to the thermal power increase (up to 33% when the flow rate varies from 0.02 m3/h and 0.06 m3/h and with a temperature change from 700 °C up to 800 °C).2) With an increase in water consumption, the outlet water temperature decreases, but the thermal power increases (up to 19% with a change in the flow rate from 0.02 m3/h to 0.06 m3/h and with a change in the outlet water temperature from 514 °C to 210 °C, at a molten metal temperature of 800 °C and a water pressure of 50.0 bar).3) Increasing the pressure of the heated water increases the thermal capacity (up to 35% when changing from 1.0 bar to50.0 bar and at a temperature of 800 ° C molten metal excess water pressure), which is due to the fact that the boiling point of water increases, and thus and a hot water heating zone with high heat capacity.4) This design of the heat exchanger allows you to achieve the necessary power for the operation of the drive by: changing the water flow rate, excess water pressure, the number of elbows, as well as by installing a heat-reflecting casing." @default.
