Improvement in Thermal Performance of Boiler in Dairy Plant: A Review

Boiler efficiency and heat transfer enhancement method play an important role in various engineering applications such as boiler, economizer, air conditioning system, chemical reactor and refrigeration system. 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 factors. Due to industry demand engineer must continuously focus on improving the thermal performance of boiler, boiler efficiency and heat transfer rate. In dairy plant problem will address heat energy wasted from 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 of economizer. Analysis of existing economizer with modified condition in CFD (Computational Fluid Dynamics). To study the pressure and temperature inside the tube.
