Feedwater to be supplied into steam boiler should pass deaerator equipment. The main function of a deaerator is to get rid of the gases contained in feedwater, in this case, feedwater had been processed and purified in water treatment plant and has functioned as initial heater before supplied into the steam boiler. Deaerator works based on the nature of oxygen solubility in water decrease with an increase in temperature. Deaerator consists of two drums where the smaller drum is for preliminary heating and exhausting gases from feedwater, while the larger drum is a shelter for feedwater that falls from a smaller drum onto it. The smaller drum contains spray nozzles that serve as spray feedwater into fine droplets of water so the heating process and exhaust gases from feedwater can be performed perfectly. The main element in determining the success of this process is physical contact between feedwater and the hot steam.
