Fangkuai has established a dual-track parallel system of ASME standards and national standards to ensure that each product can meet the world's most stringent quality requirements.

40T electrode boiler runs stably at full load at 4500 meters altitude, without altitude sickness!

"Carbon Seeking" the Roof of the World
Lack of oxygen

The oxygen content of the air is equivalent to 50% of the sea level

High and cold

The average annual temperature is -5℃ to -10℃

There is still frost at night in August

Strong wind

The annual average wind of level 8 or above reaches 150-200 days

And the evaporation is as high as 2200 mm

This is a true portrayal of the climate in Tibet

As one of the highest and most rugged areas in Tibet, Ali Prefecture is known as the "Roof on the Roof of the World". The two high-voltage electrode steam boilers designed and manufactured by Fangkuai Boiler Co., Ltd. for Zijin Mining's Ali project in Tibet have been successfully debugged and put into stable operation, becoming the leading electrode boiler demonstration project in the domestic area with an altitude of 4500 meters.
Technical advantages ensure high efficiency and stability

Faced with the influence of thin air, low air pressure, large temperature difference in high-altitude areas, and dust or humidity in some areas, Fangkuai Boiler launched an electrode steam system solution designed specifically for high-altitude scenarios, and designed the product in an all-round way to adapt to harsh environments. During this period, the Fangkuai team overcame many harsh natural conditions and construction difficulties such as high altitude, cold environment, strong wind construction, and long-distance transportation, and actively coordinated high-quality resources to ensure the smooth completion of the project.
Project progress and operation and maintenance management

After the main body of the boiler of this project was hoisted, the Fangkuai technical team formulated a full life cycle operation and maintenance plan: deploying a smart remote monitoring platform, accurate prediction, real-time monitoring, in-depth analysis, proactively discovering and blocking potential faults, greatly reducing manual maintenance costs, and reducing dependence on on-site maintenance personnel. It runs well in the high-altitude environment of 4,500 meters in Ali, successfully overcoming the dual test of terrain and environment.
Promoting energy transformation and regional development
Fangkuai Boiler has rich experience in extreme environment solutions in high-altitude cases. The successful delivery and commissioning of this project provides a better solution for clean heating in high-altitude mining areas, optimizes the energy structure of mining areas, and injects new momentum into the low-carbon development of Tibet.
