Gas Burner Upgrading.

Abstract

Abstract Factories are working on two stages – high & low flame- Liquified Petroleum Gas (LPG)burners. The two stages system works on two pressure values high & low. The project aims to workon modulating mode which means that the burner controller will select the needed capacity accordingto the real load by installing pressure transducer. Working on modulating mode will reduce therunning cost since the burner will not operate directly on the high capacity as two stages system. During running of the burner on modulating mode; the ratio between air and gas will changeaccording to the burner capacity and though there is a necessity to check that combustion is complete. In order to check if the combustion is complete; O2 sensor will be installed at the chimney. The project proposes to change the servo motor that control the air and gas cams together, to separate stepper motor for each cam to get the required angle Vs capacity. This change will give the ability to increase or decrease quantity of air and gas separately. A new controller will be added tothe main control box of the burner to connect and control the new installed devices.
