When we arrived at the factory, the first thing that caught our eyes was the well-arranged factory buildings and the busy and orderly production lines. The towering chimneys were particularly eye-catching under the blue sky and white clouds. They were not only the symbol of the factory, but also the symbol of energy conversion and transmission. Under the guidance of the staff, we put on safety equipment and prepared to go deep into the core area of ​​boiler manufacturing.

Production workshop

Here the machines roared and sparks flew. The workers were skillfully operating various mechanical equipment, turning pieces of steel plates and pipes into huge boilers through complex processes such as cutting, welding, and assembly. I noticed that the entire production process was highly automated, and many links used robots, which not only improved production efficiency, but also ensured the stability and consistency of product quality.

Combustion chamber

The fuel is fully burned in the high-efficiency burner, releasing huge heat energy; and the heat exchanger cleverly uses this heat energy to heat the water through circulation to generate steam or hot water, providing a steady stream of power for industrial production. These complex and sophisticated system designs gave me a deeper understanding of the working principle of the boiler.
In addition to the production process, we also learned about the importance of boiler safety inspection and maintenance. The staff showed us various safety protection devices of the boiler, such as overpressure protection, overtemperature protection, water level alarm, etc. These devices play a vital role in the operation of the boiler and ensure the safe and stable operation of the equipment. At the same time, regular maintenance is also essential, which can effectively extend the service life of the boiler and improve operating efficiency.

As we go deeper into the factory, we feel more and more the profoundness of the boiler manufacturing industry. From the initial design planning, to every link of production and manufacturing, to the later safety inspection and maintenance, every link embodies the wisdom and sweat of countless people. It is these unknown craftsmen who have built the cornerstone of modern industry with their hands and wisdom.

Recently, the National Factory Affairs Disclosure Coordination Group issued the "Decision on Commending the National Advanced Units for Factory Affairs Disclosure and Democratic Management in 2021-2023", and Fangkuai Boiler won the honorary title of "National Advanced Unit for Factory Affairs Disclosure and Democratic Management in 2021-2023".
 
In recent years, Fangkuai Boiler has fully implemented the Party's guiding principle of relying wholeheartedly on the working class, vigorously promoted the procedural, institutionalized and standardized construction of factory affairs disclosure and democratic management, established a factory affairs disclosure leading group, established and improved the unified leadership of the party organization, and ensured the smooth development of factory affairs disclosure and democratic management.
 
In order to fully protect the right to know, the right to participate and the right to supervise of the workers, Fangkuai fully utilizes the official website, WeChat public account, and Douyin account platform to implement factory affairs disclosure through announcements, notifications, and public notices, and regularly conducts rationalization suggestion collection, collects the opinions and suggestions of employees, and effectively solves practical difficulties for employees and smooths the channels for employees to express their demands.
 
Fangkuai Boiler will continue to enrich the carriers and content of democratic management, enhance the effectiveness of factory affairs disclosure and democratic management, stimulate and mobilize employees' enthusiasm to make suggestions and contributions to the company's business development, and help the company achieve high-quality development.

Recently, Fangkuai Boiler won the bid for 100-ton multi-energy coupling project of Jiangsu Green Harbor Smart Agriculture Industrial Park with absolute advantage. The project uses Fangkuai flue gas source heat pump technology to integrate Fangkuai's independently developed Duao D6 series double-effect deep condensing vacuum hot water boiler with heat pump. Through the efficient synergy and complementary utilization of multiple energy forms, it achieves the perfect combination of ultra-high efficiency and ultra-low emissions.
Fangkuai flue gas source heat pump technology recovers latent heat and sensible heat by optimizing the combustion process and strengthening the waste heat recovery system. The thermal efficiency is as high as 112%, the exhaust temperature is as low as 20℃, and it also plays the role of flue gas whitening. Through the intelligent control system, Fangkuai D6 boiler can flexibly adjust different energy ratios according to actual needs, maximize energy utilization efficiency, and demonstrate the technological leadership of Fangkuai boiler in the context of achieving carbon neutrality goals. NOx<30mg/m³, meeting my country's most stringent environmental protection emission standards, and providing a new solution for the green development of the agricultural industry.
Fangkuai Duao D6 series boilers are designed to achieve excellent performance with flue gas temperature as low as 20 degrees. This technological breakthrough is of great significance for energy conservation and emission reduction. Fangkuai flue gas source heat pump system can recover a large amount of heat energy from the originally discarded flue gas, which is then used in multiple links such as heating and product processing. Compared with traditional heating methods, Fangkuai flue gas source heat pump system can save more than 10% energy, greatly reducing operating costs.
As the provider of this technology, Fangkuai Boiler's R&D team said that Fangkuai flue gas source heat pump system is an innovative practice based on the concept of deep recovery of industrial waste heat, aiming to provide cleaner and more efficient energy utilization solutions for all walks of life. It can be widely used in residential communities, regional heating single buildings, regional heating stations, large commercial complexes, industrial production and other heating projects.

In the future, Fangkuai Boiler will continue to explore more energy-saving and emission reduction technologies to help various industries transform to a low-carbon and environmentally friendly production model. Under the guidance of the "dual carbon" goal, we will consciously shoulder the historical mission, actively respond to challenges, and contribute "Fangkuai wisdom" to the country's smooth realization of the carbon neutrality goal!
