Abstract |
Now a days energy is very important. Energy saving is one of the important issues, not only from the point of view of fuel consumption but also for the protection of global environment. So, it is very important that a significant effort should be made for conserving energy through waste heat. In the present scenario most of the production process, industries consider boiler efficiency is a major factor. Due to industry demand engineer must continuously focus on improving the thermal performance of boiler. This project will address the problem of heat energy is wasted from dairy plant in the form of condensed water. The main object is to recover waste heat water from the system to recirculate to the economizer for efficiency improvement and enhance heat transfer rate. Analysis of existing economizer in dairy plant with modified condition in CFD (Computational Fluid Dynamics). To study the temperature and pressure inside the tube. In this paper simulation of economizer zone of boiler, from one of the dairy plant is consider economizer in preheat boiler feed water before enter into the boiler. Economizer use waste heat flue gases for steam production. Best ways of consumption of flue gases heat is transferring it to the boiler feed water. The model is solved using conventional CFD techniques by ANSYS software and simulation was carried out in ANSYS®FLUENT®v16. The Computational Fluid Dynamics (CFD) approached is utilised for the creation of three dimensional model of the economizer. With equilibrium assumption applied for description of the system chemistry. The condensed water temperature, pressure and velocity field of fluid flow within an economizer tube using the actual boundary conditions have been analyzed using CFD tool. |
