Entering Zozen - Exploring the "Mysteries" of Boiler Production

  The boiler is divided into two parts: "pot" and "furnace". The "pot" is a pressurized part that contains water and steam. It heats, vaporizes, and separates steam. The "furnace" is a place where fuel is burned or other heat is released. It has a combustion device and a combustion chamber and a heat release flue. Wait. In addition to pots and furnaces, there are auxiliary equipment such as frames, platforms, escalators, burning, slagging, smoke ducts, pipes, furnace walls, etc.

  After more than 50 years of development, China's boiler industry has formed a relatively complete product system, and its technical level is gradually in line with the developed countries. With the rapid development of the national economy and the continuous improvement of people’s lives, the industrial boiler industry in China has been growing at a faster rate in recent years and its output has been increasing. So far, China has been the country with the largest production and use of boilers in the world today.

  Figure 1: National Industrial Boiler Production Statistics for January-July 2017

  According to the statistics in Figure 1, the national industrial boiler output in July 2017 was 40,624.6 tons of steam tons, and the monthly growth rate was 2.78%. From January to July in 2017, the total industrial boiler production in the country was 24,7044.7 tons, a cumulative increase of 3.62% over the same period of the previous year. . In summary, the important status of the boiler industry in China’s national economic development has become increasingly significant.

  However, at present, there are many boiler manufacturers in China, and the development of the industry is uneven. It is very important for the users to choose a good manufacturer and a good boiler. A good boiler product means mature technology, stable operation, low failure rate, and ease of use. But how to choose a good boiler factory?

  Today, Xiao Bian will take you into Zhongzheng, a designated manufacturer of boilers approved by the General Administration of Quality Supervision, Inspection and Quarantine, to explore the “mysteries” of boiler production and choose the right and durable boiler for you.

  Zhongzheng is located in Yixing, a beautiful coast of Taihu Lake. The plant covers an area of ​​about 120,000 square meters, including blanking workshop, drum and drum workshop, metalworking workshop, membrane wall workshop, organic heat carrier furnace workshop, assembly workshop, and final assembly. Workshops, welding workshops, etc. In 2004, Zhongzheng passed the ISO9001 international quality management system certification, and strictly controlled all aspects of production to ensure that each manufactured boiler is a high-quality equipment.

  For example, in recent years, the company has implemented a large-scale welding process revolution, intensified its welding work and improved its technological level, gradually eliminated manual welding operations with low efficiency and poor stability, and adopted high-efficiency and good-stability mechanical welding and automatic welding for production. Welding, as a major technical highlight of Zhongzheng, adopts mechanical (automatic) welded pressure welds, and the average pass rate for filming is more than 99% on average.

  Secondly, for the assembly of products, Zhongzheng also innovated to realize assembly molds, gradually reduced the traditional processing methods of scribing assembly, eliminated scribing errors, and ensured that the manufactured boilers were uniform and uniform.

  In addition, Zhongzheng's detection means is complete, equipped with 100T universal material testing machine, metallographic microscope, ray detection equipment, hardness tester, spectrum analyzer large heat treatment furnace, full-time inspection, strict control, eliminate the factory failed boiler products.

  With more than 20 years of experience in the production of boilers, Zhongzheng has already achieved professional and large-scale production of all major components in boiler products. At present, there are about 400 kinds of boilers covering gas boilers, coal-fired boilers, biomass boilers, and heat-conducting oil boilers, which can meet the needs of all walks of life. So far, the application of Zhongzheng boilers has covered more than 13 industries. From the statistics of the boiler sales of the Zhongzheng Sales Department in the following figures from 2015 to 2017, the average service enterprise volume of Zhongzheng is as high as 1,200 in the past three years.

Boiler classification Quantity/Taiwan
Gas boilers 1862
Coal-fired boilers 1448
Biomass boiler 123
Thermal oil furnace 321

  In order to meet the service needs of a large number of companies, Zhongzheng has successively established more than 30 offices throughout the country. At the same time, in order to comply with the development trend of globalization, “China-Zhengzheng” has been in line with international standards. Currently, Zhongzheng has annual large-volume boilers sold to Southeast Asia, South Asia, West Asia, South America, Eastern Europe and African countries, and in Germany, Indonesia, Philippines, Thailand. , Vietnam and Taiwan have established service centers to provide customers with comprehensive technical services such as project technical consultation, plan production, installation guidance, and technical training.
