A power plant? It should be a powerhouse! Even if you meet me, most people really can't answer such a professional question.
1. The ingredients are usually chemicals such as polyaluminum chloride, aluminum sulfate, ferrous sulfate, alum, etc. Clarifier is used for coagulation.
2. The ingredients are generally polyacrylamide, polysodium methacrylate, etc., which are used to help the coagulant achieve coagulation.
3. Fungicides. There are sodium hypochlorite, calcium hypochlorite, chlorine dioxide, chlorine, ozone, etc. Mainly plays a bactericidal role.
4. Reducing agent. Sometimes, in order to reduce excess added fungicide, a reducing agent is also used. Sodium bisulfite is generally used.
5. Ammonia. Used to adjust the pH value of feed water andcondensate water.
6. Hydrazine. It is used for chemical deoxidation, that is, to reduce dissolved oxygen in water.
7. Acids. Hydrochloric acid and sulfuric acid are mainly used and nitric acid is rarely used. It is mainly used for regenerating cation exchange resin and emergency treatment of ash system scale.
8. Mainly sodium hydroxide and potassium hydroxide. Sodium hydroxide is used to reanimate the anion exchange resin. Potassium hydroxide is used to produce hydrogen through electrolysis.
I've thought about it for now, if I think about it again I'll add more!
What is the chemical water used in power plants?
Recently, many people are interested in the specialties of water treatment and chemical supervision in thermal power plants , and they never stop wonderingand what they can do. after graduation? So today, we The editor will give you an analysis!
What do graduates of thermal power plant water treatment and chemical supervision specializations do?
Training objectives: This specialization trains personnel in water treatment and chemical supervision in thermal power plants. The main contents of vocational education include basic chemistry, analytical fuel chemistry for human power plants, water treatment of thermal power plants, chemical instrumentation and automation of power plants, processes of production of thermal power plants, etc.
Employment directions: national powerhouses, employers, etc.
The main courses include steam system water treatment, natural water and its water quality characteristics, basic knowledgeon water chemistry, external furnace water treatment, thermal system equipment corrosion and its prevention, steam pollution and its prevention, and energy. oil. Comprehensive practical training on chemical analysis in power plants and comprehensive practical training on chemical instrumentation in power plants; comprehensive practical training on drawing thermal systems in thermal power plants; comprehensive hands-on training in water treatment and chemical supervision; in thermal power plants

The treated desalinated water sends it to boilers or desuperheaters and others. equipment to be used;
Another task of chemical water is water quality monitoring, which is to monitor the superheated steam from the boiler,saturated steam, water in the drum, etc. are regularly sampled and tested. If not qualified, the boiler must be treated with chemicals;
Sometimes the water chemical station takes over part of the laboratory functions and tests the main auxiliary. power plant materials, such as lime for desulfurization, raw coal quality testing (calorific value, ash content, moisture, volatile matterislands, sulfur content, etc.);
If the power plant has a sewage treatment plant, it must also undertake the task of wastewater treatment. Learn about sewage sedimentation, CASS regulating tank aeration, decanter, sludge removal with filter, etc.
