pH value

The pH value is the measure of a solution's acidity or alkalinity. A pH value of 7 corresponds to the neutral point between the two. Values below 7 indicate an acid, values greater than 7 an alkali (base). Condensation processes can lead to the creation of sulphuric acid, particularly when combusting non-low-sulphur fuel oils, which in turn reduces the pH value of the condensate to less than seven. The pH value of the condensate from condensing boilers fired on low-sulphur fuel oils is comparable with that of gas fired units.
