We are providing to solution to measure steam data and save your power plant efficiency.

Because corrosion and erosion are major concerns in thermal power plants operating on steam. The steam reaching the turbines need to be ultra-pure and hence needs to be monitored for its quality. A well designed Steam and Water Analysis system (SWAS) can help in monitoring the critical parameters in the steam. These parameters include pH, conductivity, silica, sodium, dissolved oxygen, phosphate and chlorides. A well designed SWAS must ensure that the sample is representative till the point of analysis. To achieve this, it is important to take care of the following aspects of the sample:

• Sample Extraction
• Sample Transport
• Conditioning
• Analysis
• Controls

When it comes to safety and efficiency of the steam turbine and boiler in a power plant, silica becomes one of the most critical factors to be monitored. Deposition of various impurities on turbine blades has been identified as one of the most common problems. Various compounds deposit on the turbine blades. Of all these compounds, silica (SiO2) deposits can occur at lower operating pressures also.[14] Therefore, silica deposition is quite common in turbines than other types of deposits. Silica usually deposits in the intermediate-pressure and low-pressure sections of the turbine. These deposits are hard to remove, disturb the geometry of turbine blades and ultimately result in vibrations causing imbalance and loss of output from turbine.

Another important area of concern as far as silica deposition is concerned is boiler tube. Silica scale is one of the hardest scale to remove. Because of its low thermal conductivity, a very thin silica deposit can reduce heat transfer considerably, reducing efficiency, leading to hot spots and ultimately ruptures.

Because of all these issues, it is extremely important to closely monitor silica levels by using on-line silica analyzers that can measure silica levels to a ppb (parts per billion) level.
