Design and fabrication of infra red oven

Abstract

This project is designed to improve Electrical versus Thermal efficiency. Nowadays electrical heating system converts 65% of the electrical power into thermal power. We have introduced infrared penetration heating system to improve efficiency up to 95% thermal efficiency and 100% electrical efficiency. We are going to construct a oven model to improve our system. A real fabrication model is to analyze IR heating system. The capacity of infrared lamps used inside the oven will be about 500watts. IR lamps will be used to provide heat. From the OVEN, the temperature is sensed by the thermocouple, which is based on the principle of Seeback effect. The function of a thermocouple is to convert heat energy to mill voltage and it is fed to a signal conditioner to improve the sensitivity and also to improve the non-linear Property of thermocouple. Temperature acquired from the thermocouple is indicated on the screen of the computer. The computer will also compare the temperature acquired with the set temperature and control action if any will be done by the solid-state relay that avoids instantaneous heating. The infrared (IR) heating has the potential to be used for solution zing of metal forgings with benefits of reduced energy consumption, increased productivity, and improved microstructure and mechanical properties. In our project, we have integrated heat treatment, annealing, oven and oven operations are done in a single device. So that the cost of equipment for each process and time taken are reduced.
