ABB Navigator 600 silica analyzer Combined cycle power

water-steam turbine cycle. In the boiler silica forms sili-cate deposits that interfere with heat transfer and are very difficult to remove. In the turbine, silica deposits on the blades and causes drastic decreases in effi-ciency. Power plants with high pressure boilers close-ly monitor silica concentrations to avoid these prob-lems.

In boilers, the source of this corrosion is excessive use of hydrazine, or leaking internal de-super-heater elements in boiler drums, which allow alkaline boiler water to enter the de-super-heater steam system and corrode copper and copper alloys, bringing the copper to the boiler.

BASIC WATER TREATMENT OF STEAM BOILERS

Causes of Poor Steam Purity. •Foaming in the boiler caused by organic contamination (oil, high total organics from the makeup water, high boiler water TDS). •High chemical contamination caused by excessive TDS due to lack of boiler blowdown. •Excessive alkalinity due to excess hydroxide feed in the boiler water.

Generally it should not exceed 05 cc per liter O2

The water carried over with steam due to above reasons is exactly similar in quality to blow-down or boiler water. In superheater or in turbines, water evaporates, leaving dissolved and suspended matter as scales or deposits. Thus severity of scaling and fouling of superheater and turbine depends on boiler water quality and steam purity.
