| dc.description.abstract | The boiler is a vessel containing water where the water is continuous diupkan and
forms of heating steam coming from the kitchen fire. Therefore, the use of boiler
water must always be in control to match the standard. If the pH and alkalinity
levels high, it can cause corrosion, crust on the inner wall of the boiler which can
cause damage to the boiler and reduce the quality of steam produced.Air stuffing
used for boiler use water reservoirs cottage En Anêm were taken for three days.
Analysis using a pH meter pH and alkalinity analysis using methods titrimetri
where H2SO4 0,02 N is used as the standard solution.Based on the analysis carried
out on the boiler feed water in PTPN III PKS Aek South Nabara for pH at 11.1;
11.0 and 11.1. And for alkalnitas namely 590, 620 and 630 ppm CaCO3. Then the
boiler feed water at PTPN III PKS Aek South Nabara meets the standards PTPN
III PKS Aek South Nabara. | en_US |
