Abstract :
Heat Recovery Steam Generator is a plant that is used to streamline exhaust gas from PLTG which is then combined with PLTU (combined cycle) which produces a PLTGU. HRSG is a medium for expanding the remainder of the exhaust gas as a result of Turbine Gas rotation, through Fin and Tube as a medium to absorb heat / heat from the exhaust gas to form / make steam. The water content used is very influential on tube material which can make sediment or corrosion. If the water content is too acidic, corrosion will occur, but conversely if it is too acidic it will form a crustal deposit. It can inhibit heat transfer so that the resulting steam becomes reduced / decreases steam production. Therefore maintenance of the equipment in the combined cycle system must be considered to support the efficiency of the PLTGU so that it is always good and optimal
