Case introduction

At Linxian Senior High School in Shanxi Province, hot water boilers are essential for providing reliable winter heating and a steady supply of hot water for dormitories, classrooms, and bathrooms. The school recognizes the importance of fostering an optimal learning environment and continually seeks to enhance the quality of life for its students.

To align with national initiatives like "coal to gas," Linxian Senior High School decided to upgrade its energy systems by replacing traditional coal-fired boilers with cleaner, more sustainable gas boilers. This transition aims to create a healthier and more eco-friendly atmosphere for the entire school community.

After careful evaluation of leading brands in the boiler industry, the school chose to partner with Fangkuai Boiler. Known for its advanced clean fuel technology and exceptional product quality, Fangkuai was the ideal choice for this initiative. The collaboration resulted in the installation of a state-of-the-art 4.2MW integrated condensing gas hot water boiler (model: WNS4.2-1.0/115/70-Y.Q).

This innovative boiler features a horizontal wet-back center backfire structure, maximizing energy efficiency by recycling flue gas waste heat. By reducing the exhaust gas temperature to approximately 60°C, the system achieves an impressive thermal efficiency of about 98%, surpassing traditional models by over 10%.

The upgrade has transformed the learning environment at Linxian Senior High School, providing a comfortable and warm atmosphere for students and teachers alike. Additionally, the school’s commitment to green development and environmental responsibility has been reinforced, establishing it as a leader in sustainable practices in education.
