1 do a good job in water supply treatment: Dissolved oxygen, iron ions and low pH values in the feed water all contribute to corrosion of boiler metals. Therefore, water supply should be deaerated as far as possible, feed water pH value should be greater than 7; Attention should be paid to the control of iron ion content for the recovery of steam condensing water for feedwater. Sometimes the condensation water usually contains yellow rust water as soon as the steam system is started. At this time, it should be properly discharged until the iron content is qualified before it can be used as boiler feed water.
2 keep the water quality of the pot up to standard: Generally speaking, too high salt and chlorine content in pot water, too low or too high pH value and alkalinity will increase corrosion. Therefore, it is necessary to discharge water reasonably, maintain a certain pH value, alkalinity and PO43- content of boiler water in order to keep the quality of boiler water up to standard, which can not only prevent scaling, but also be beneficial to anticorrosion.
3 prevent subscale corrosion: After scaling on the heated surface of the boiler, the pot water infiltrated under the scale will be extremely concentrated at high temperature and chemical reaction will take place, resulting in all kinds of scale corrosion, but the coverage of the scale is often difficult to detect. Therefore, boiler scaling should be cleaned and removed in time.
4. To form a protective film on the surface of the metal: For newly installed boilers, a good cooking effect should enable the metal surface to form a complete passivation protective film. Under the operating conditions, when the pot water maintains a suitable pH value (generally 10 μ 12) and a certain amount of phosphate and carbonate, it is also helpful to form a dense protective film on the surface of the metal and slow down the corrosion. However, if the boiler water quality is not well controlled, especially if the pH value is too low or too high, the protective film will often be destroyed.
5 do a good job of shut-down and maintenance: The corrosion of many boilers is often caused by improper maintenance when the boiler is shut down, and the corrosion products produced when the boiler is shut down are often accelerated when the boiler is in operation. Therefore, when shutting down the furnace, the maintenance work must be done in accordance with the requirements of the regulations.
Boiler superheater and reheater difference and a secondary air ratio explanation: the boiler, because it is the site of the main and important product, so its knowledge and understanding, is necessary to achieve a comprehensive and specific, and, on its knowledge of the content, you can not have a shred of omission. So, in order to let everyone compliance as soon as possible, and at the same time, can also be the proper use of the boiler, below, followed by a wish to learn of its work, beating let us benefit from it. 1. On the boiler manufacture and installation, for manufacturers, what are the requirements? In addition, the boiler water, which generally have several situations? Boiler manufacture and installation of the manufacturer, the provisions of its requirements, is: has made manufacturing unit boiler manufacturing license, boiler units for benzene product transformation and installation is no need to obtain a permit of another. Boiler water, generally speaking, is there are two cases, one is a slight lack of water, the second is a serious water shortage.
10 tph SZL series coal-fired boiler for textile industry
The process of dyeing, drying, pressing, sizing, printing and dyeing, shaping and other processes in the textile industry are supported by the steam. Therefore, steam boilers are important equipment to ensure the normal production process of textiles. SOORTY is one of the largest vertically integrated denim manufacturers from Pakistan. Production capacity of 60 tons yarn per day, 5.5 million meters fabric per month and 2.8 million garments per month makes them leader of the league.
Coal-fired boiler not only seriously polluted air, which produces a large amount of waste water sludge can also cause serious water pollution and soil contamination. To protect the city of Tongren green water blue sky, since 2014, led by the city of Tongren City, Guizhou Bureau of Quality Supervision, of 10 steam tons / hour within built-up areas and Tongren City High-tech Zone, Economic Development Zone, Tai Lung range and below, in Guizhou tobacco industry limited liability company Tongren cigarette factory, Tongren City, drug rehabilitation centers, Tongren Wantong construction and development Co., Ltd. and other 36 enterprises of coal-fired boilers to carry out an intensive diagnostic investigation. One by one on the ground to verify the registration, and the companies signed an undertaking to ban coal-fired boilers eliminated; to effectively reduce the burden on enterprises, according to the spirit of the document, to take the initiative within the time limit or eliminate the use of coal-fired boiler unit to switch to clean energy, the after review and acceptance Municipal Environmental Protection Bureau, according to the amount of coal-fired boilers hour evaporation reward, award criteria tons of steam per 30,000 yuan subsidy.
Up to now, the city of Tongren out of 36 coal-fired boiler units, a total of 43.051 tons of steam, an award subsidies 1,291,530 yuan, so far, the city of Tongren jurisdictions total phase-out of all coal-fired boilers, and lay a good foundation for the creation of ecological civilization demonstration area.
