Product Description Power generation boilers use fuels such as coal, oil or natural gas to hear water and therefore produce steam, which is in turn used to drive turbine generators. The economics of power generation rely to a great extent on the efficiency of the fuel to heat conversion process and therefore the power generation industry are amongst the most advanced users of efficiency techniques based on on-line process analysis. STEAM & WATER ANALYSIS SYSTEM are 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 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 to 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, indication of corrosion and detection of cooling water leaks in the condense stage.Detailed PhotosWhat's the technical specification of Manufacturer water ph probe usb ph sensor?PHG-2081X pH MeterMeasuring range: 0-14pHTemperature range:0-60oCCompressive strength:0.3MPaSlope: ≥96%Zero point potential: E0=7PH±0.3Internal impedance: 150-250 MΩ (25oC)Profile: 3-in-1Electrode (Integrating the temperature compensation and the solution grounding)Installation size: Upper and Lower 3/4NPT Pipe ThreadConnection: Low-noise cable goes out directly.Application: Applicable to various industrial sewages, environmental protection and water treatment.What's the technical specification of Online Conductivity Meter?

In power plant production, water is also a medium. In the specific power process, water is needed to transfer heat and power. If the water in the boiler contains excessive impurities, impurities will deposit at the bottom of the boiler, resulting in uneven heating. If the water quality of the boiler can not be treated for a long time, it will also cause certain damage to the boiler, affecting the service life of the boiler. In serious cases, corrosion, scaling and bulging of the boiler also need to occur. The explosion accident was caused by some problems. If the water quality contains a large amount of calcium and magnesium ions, impurities will continue to concentrate and evaporate in the boiler, resulting in scales accumulated at the bottom of the boiler, affecting heat transfer efficiency, resulting in a large number of unnecessary fuel consumption. Therefore, the quality of boiler water has a very important impact on the economy of power enterprise production and greenhouse gas emissions.the water for boiler we classify hard water and soft water in power plant.2.What is Effect and Characteristics of Hard Water into BoilerHard water refers to the hardness of relatively small, hard water contains a large number of sodium ions, magnesium ions and calcium ions. These impurities are continuously concentrated, evaporated and heated in the boiler. Ions in the boiler water tend to be saturated in the process of changing the depth of salts. The solid matter produced is mainly calcium carbonate. When calcium carbonate accumulates for a long time, a large amount of heat will be concentrated at the bottom of the boiler, which may cause the boiler explosion. This requires the power plant staff to strengthen the cleaning and maintenance of the boiler in their daily work, but also to use various means to reduce the hardness of water.
