Internal Processing.

In boiler water treatment aimed at controlling corrosion, scale and foam that comes with the addition of chemicals. Corrosion can be prevented by removal of oxygen and adjust the pH is alkaline. Crust (scaling) is controlled by binding hardness in water. To control scale and corrosion are used WQ containing sodium bisulfite and sodium triphosphate. Sodium bisulfite will bind oxygen so that corrosion can be avoided. 'm Natritum phosphate compounds will react with the cause of hardness 356 to form Ca3 (PO4) 2 in the form of mud and tend to settle at alkaline pH. Mud will gather at the bottom of the kettle and was issued with the blowdown.

2 NaHS03 + O2 -> 2 NaHSO4
2 Na3PO4.12 H2O + 3 CaCO3 -> Ca3 (PO4) 2 + 3 Na2CO3 + 4 H2O
2 Na3PO4.12 H2O + 3 CaSO4 -> C43 (PO4) 2 + 3 Na2SO4 + 2 H2O
Cooling Tower (cooling tower)

Cooling tower water used to cool the condensate before entering into the kettle. Water is passed on the lattice - the lattice, forming a curtain of water and given a blower at the top to suck out hot air and in the lattice.

Some cooling tower made of red wood, which is a kind of wood is very resistant (durable) if the constant contact with the water 357. Material Form (internal packing) is usually a wooden structure that is placed horizontally. Tower space is very large, usually more than 90% so that the pressure drop (pressure drop) of air can be as low as possible.

Surface area of contact between air and water not only on the liquid film on the surface of the packing, but also on the surface of water droplets falling and resembles the rain. The flow of air and water in the cooling tower can be cross or opposite directions (counter current) or a combination of both.
