Análisis y simulación mediante Fluent de Ansys del proceso de calentamiento de una piscina de 25 M3 con vapor de agua sobrecalentado proveniente de una caldera pirotubular

Abstract

The objective of this technical research project is to analyze the heating process of a swimming pool with a capacity of 25 m3, with the use of superheated steam from a fire tube boiler that, registering a copper pipe, places heat in the water deposited in said pool thus raising its initial temperature, the study methods used for the described process are: the analytical method and the numerical method, the use of computer tools: Excel, Steam calculator, EES, Inventor and fluent from ANSYS. The initial conditions of the superheated steam are 150 °C to 400 kPa and the pool is expected to go from an initial temperature of 18 °C to 30 °C by natural convection; working with a mass flow of 1000 kg/h and having a pipe length of 13.33 m, the approximate caloric energy rate that superheated steam releases is 26.1412 kW, while the amount of caloric energy required by the total volume of water inside the pool to complete the heating process is 1251332.256 kJ, so it is estimated that this heat transfer takes place over a period of 13 hours 17 minutes, in addition to this a slight pressure drop is shown and an expected drop in temperature of the superheated steam upon completion of the tour. As detailed in the figures that describe the behavior of the process, it is concluded that the parameters that most influence the time it takes to carry out heating are: the production of steam and the area of heat transfer.
