AUTOMATED DOMESTIC GAS STOVE WITH MANUAL AND SERVO VALVE CONTROLLED, INDEPENDENTLY FLOODED CONCENTRIC GAS BURNER

In conventional gas stoves there will be two or more burners for different sized vessels. In this work, a single, independently flooded concentric gas burner is designed, producing different circumferential flames to accommodate different sized vessel. This project is mainly concerned with the design and fabrication of a single innovative gas burner which can produce variable circumferential flames depending on the base diameter of the cooking vessel. Here three different sized gas burners are arranged concentrically such that the gas through the individual burner can be controlled independently. The gas burner receives the controlled gas flow rate by 4- ports 4-position rotary servo valve. Ultrasonic sensor is placed in the gas stove in appropriate location to sense the diameter of the vessel. The signal generated by ultrasonic sensors is sent to the microcontroller which will generate signal to the servomotor which controls the control valve automatically, there by flooding the gas to the required burner chamber.
