In order to produce steam, combustion is required. Combustion is an exothermic reaction that takes place very quickly, which liberates energy in the form of heat and flame (flame temperature) and is able to spread heat through a medium. Based on the shortcomings in the previous research, an upgrade to the Boiler feed Water injection system and the combustion air secondary control system will be carried out. In the injection boiler feed water system, changes are made to the pumping system that is resistant to back pressure and heat resistance. For the secondary combustion air system, it will be supported using a blower and flow meter so that the rate of air supply will be controlled. Next is the water level control system on the drum so that the water inside will be calm and read by the water level gauge when the process is running. By upgrading the three systems, it is expected that the steam production process will be able to take place in a steady state or continuously improve the thermal efficiency of the water tube boiler. The fuel used is LPG gas.
