APPLICATION

Power plant of steam and water analysis system(SWAS)

Power generation boilers use fuels such as coal, oil, or natural gas to heat water and therefore produce steam, which is in turn used to drive turbine generators. The economics of power generation relies to a great extent on the efficiency of the fuel to heat conversion process and therefore the power generation industry is amongst the most advanced users of efficiency techniques based on online process analysis.

STEAM & WATER ANALYSIS SYSTEM is used in power plants and in those industrial processes where it is needed to CONTROL AND MONITOR WATER QUALITY. In power plants, it is needed to control the water/steam cycle characteristics in order to avoid damage to the components of the circuit as the steam turbine and the boilers.

Within the power station, the aim of water and steam control is to minimize contamination of the circuit, thereby reducing corrosion as well as cutting down the risk of the formation of harmful impurities. Therefore it is very important to control the quality of water to prevent the deposits on turbine blades by Silica (SiO2), reduce corrosion by dissolved oxygen (DO), or prevent acid corrosion by Hydrazine (N2H4). Measurement of water conductivity gives an excellent initial indication of falling water quality, analysis of Chlorine (Cl2), Ozone (O3), and Chloride (Cl) used for control of cooling water disinfecting, an indication of corrosion, and detection of cooling water leaks in the condense stage.

The interface must be in 15°oblique angle, or it will affect the normal test and use of the electrode. We won’t

be responsible for any results due to this.
