Industrial boilers are one of the necessary equipment in many industrial industries. The high-temperature steam output by the boiler and the heat it brings can provide a source of power for the industrialized process. Zhengzhou Fangkuai Boiler Factory, as a company with many years of cooperation experience in the field of industrial boilers, has a lot of knowledge about boiler operation, maintenance, and maintenance. Today, I will tell you how much damage is caused by scaling to industrial boilers.
First of all, after the formation of scale inside the industrial boiler, the heat transfer performance of the heating surface becomes poor, and the heat released when the fuel is burned cannot be quickly transferred to the boiler water; therefore, a large amount of heat is taken away by the flue gas, causing the exhaust gas temperature to rise and increase The heat loss of exhaust gas reduces the thermal efficiency of the boiler.
Secondly, it may cause overheating and low strength of the metal, endangering safety. The steel used for the heating surface of industrial boilers is generally carbon steel. During use, the metal wall temperature is allowed to be below 450 ℃; when the boiler is in normal operation, the metal wall temperature is generally below 280 ℃. When there is no scale on the heating surface of the boiler, the metal can quickly transfer heat to the water after being heated. At this time, the temperature difference between the two is about 30 ℃. However, if scale accumulates on the heated surface, the temperature difference between the two will increase. For example: when the heating surface of a boiler with a working pressure of 1.25Mpa has 1 mm thick scale (mixed scale), the temperature difference between the metal wall and the boiler water will reach about 200 ℃; when the scale reaches 3 mm, the metal wall temperature will rise to 580 ℃, far exceeds the allowable temperature of steel. At this time, the tensile strength of the steel will be reduced, and the pressure components of the boiler will overheat, bulge, deform, leak, and even explode under the action of internal pressure. The measured data shows that the metal wall temperature increases as the scale thickness increases. The thicker the scale, the higher the metal wall temperature, and the greater the probability of accidents.
The water circulation of industrial boilers has two forms: natural water circulation and forced water circulation. The natural water cycle is a water cycle that relies on the pressure difference caused by the difference in the specific gravity of soda and water in the riser pipe and the down pipe. Forced water circulation depends on the mechanical power of the water pump to force the circulation. Regardless of which form of water circulation, it is designed and calculated, which means that there is enough circulation cross-sectional area. When scale builds up on the inner wall of the furnace tube, the circulation area in the tube is reduced, the flow resistance increases, the normal water circulation is destroyed, and the metal wall temperature toward the fire surface rises. When the pipeline is blocked by scale, the water circulation is completely stopped, and the metal wall temperature is higher, and pipe burst accidents will occur for a long time.
Once the industrial boiler scales, it must be removed quickly, so as to ensure the safe and economical operation of the boiler. The later the scale builds up, the more medicine is consumed, and the more money is invested. For example, if the average fouling of a 1t/h boiler is 3 mm, 0.5 tons of chemicals are required to remove the fouling once. After increasing according to the different boiler tonnage, the required reagent will increase by one-third, and the investment capital will increase accordingly.
The service life of general industrial boilers can run continuously for about 20 years under normal use conditions. However, most of the boilers of the current use units have not reached this life. There are many reasons for this, one of which is the influence of scale. The drum has a bulge, and after digging and repairing it, it should be properly reduced in pressure to ensure safety. In this way, for units that require high steam pressure, they have to replace a new boiler.
With the boomingdevelopment of the mobile Internet industry, new technologies, new services and data centers are becoming more and more closely related, and all walks of life are growing rapidly in the "cloud". The massive data processing needs make the Internet industry face new challengesof the era of comprehensive cloudification of data storage and transmission modes. In this context, cloud computing integrates various forces to form a joint force, which brings convenience to the development of various tasks and creates a new business model.
As the backbone of the special equipment manufacturing industry, Fangkuai Boiler also follows the general trend of the development of the cloud era and deepens the social driving force of "cloud data". Leading the development of the industry, Fangkuai Boiler will facethe situation of opportunities and challenges.

As a comprehensive international trade event with the longest history, highest level, largest scale, most complete product variety, and best transaction effect in China, the Canton Fair has also been favored by many well-known domestic and foreign companies, and has contributed to the promotion of economic globalization.
Affected by the international epidemic situation, the Canton Fair is also flexible and adaptable, with the help of the global interconnection, it is held online.
As one of the countries along the “Belt and Road”, Uzbekistan has maintained friendly economic and trade relations with my country. This time, with the aid of the long-term economic cooperation between China and Uzbekistan, Fangkuai Boiler Company has also reached a long-term strategic cooperative relationship with a local trading company in Uzbekistan. This is undoubtedly a further expansion of Uzbekistan and other companies for FANGKUAI Boiler Company. The international market in Central Asia.
The company that cooperated with Fangkuai Boiler Company this time is a well-known local trading company in Uzbekistan, which involves many industries such as food processing, raw oil and automobile manufacturing. The establishment of this partnership also laid a solid foundation for FANGKUAI Boiler to expand local food, chemical, automotive and other industries.
The company attaches great importance to this cross-border cooperation, and has sent several teams to visit the mainland of China. After a comprehensive evaluation of the company's overall strength, advanced technology and after-sales service, it was determined that FANGKUAI Boiler is a very worthy enterprise, and the two parties reached a good cooperation.
This year, FANGKUAI Boiler accepted investigations from leaders of the National Committee of the Chinese People's Political Consultative Conference, Comrade Jiang Zuojun, Deputy Secretary-General, Comrade He Jinping, Deputy Governor of Henan Province, Investigation Team of the Provincial People's Congress, Deputy Secretary of Anyang, and Mayor Jin Lei And inspections, and with the strong professional technology and various research and development results have been praised and encouraged by superior leaders.
This year, FANGKUAI Boiler brought a variety of boiler products to China International Corrugated Paper, Beijing ISH, 2019 Pharmaceutical Expo, auto parts and other industry exhibitions.
