Generally speaking there are two different types of lead acid battery, Starting and Deep Cycle. If a starting battery is routinely deep cycled (discharged below 20%-50% of max capacity) it will generally fail after 30-150 cycles. The same starting battery will last for thousands of cycles if it is just used normally (2% - 5% discharge).
These phosphates precipitate the solids to the bottom of the boiler drum. At the bottom of the boiler drum there is a bottom blow to remove these solids. These chemicals also include anti-scaling agents, oxygen scavengers, and anti-foaming agents.
A boiler water treatment programâs primary function is to keep heat transfer surfaces (steam-generating and associated tubes) free from scale and deposition. The second function is to inhibit corrosion. Boiler deposits are problematic because they typically contain undesirable levels of metal oxides, mineral scale, sludge, or various combinations. Corrosion generally occurs because of excessive levels of dissolved oxygen, but can also develop under tube deposits.
