Another test which is sometimes used as a gauge of solids is to measure the chloride present in the boiler water. The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blowdown required. The test is unsuitable for feedwater with low incoming concentrations and the concentrations in the feedwater must be averaged over time for
