The worlds largest oxy-fuel photovoltaic glass furnace was recently ignited in Hefei.

Nanjing Baisheng Glass Technology Co., Ltd. and Nanjing Baisheng Kiln Engineering Co., Ltd. were established in February 2006 and January 2014 respectively. Is a professional company engaged in glass factory (kiln) design, kiln (equipment) construction and installation and glass production technical services. The company mainly serves the glass factory design of flat glass, photovoltaic calendered glass, electric light source glass, daily-use glass, water glass and ceramic frit production lines, glass engineering installation and construction, firing and baking kiln, commissioning and related technical training, technical services, and professional companies for hot and cold repair of glass kilns.

The world's largest oxy-fuel photovoltaic glass kiln was recently ignited in Hefei, and the development of Rainbow (Hefei) photovoltaic glass phase II project entered a new stage.

"Rainbow Group entered Hefei in 2011 and invested in three major projects in succession. Hefei has become one of the most important industrial bases of Rainbow Group." Si Yuncong, general manager of China Electronic Rainbow Group, said that the Hefei municipal government is very pro-business, and the group plans to further increase its investment in Hefei to achieve common development.

It is reported that the project has a total investment of 750 million yuan to build an all-oxygen burning photovoltaic glass furnace with an extraction capacity of 800 tons/day, and it is supported by four single-line calendering glass production lines with a capacity of 200 tons/day and corresponding glass coating and tempering production lines. The construction period of the project is 12 months. This means that after the project is put into production, the annual output of 3.2mm thick coated tempered photovoltaic glass is 24.8 million square meters, which can support 3.5GW photovoltaic modules. After the completion of this project, Rainbow (Hefei) Photovoltaic Park will become the world's largest production base of oxy-fuel single photovoltaic glass, with an annual output value of 1.2 billion yuan.

"The oxy-fuel combustion kiln has the advantages of low energy consumption, low emission and high quality. Compared with ordinary kilns, it is 30% energy-saving, green and environmentally friendly. The flue gas emission index of the kiln is far below the national standard, and the yield rate reaches the leading level in the industry." Xiaoning Chen, general manager of Rainbow Hefei Photovoltaic, told the reporter that the high-tech content of this project makes full use of the mature technology and industrialization technology of the super-large photovoltaic glass oxy-fuel burning kiln in the first phase of Rainbow Hefei Photovoltaic, ensuring safety, stability and technical reliability.

The reporter learned that the second phase of Rainbow includes the construction of kiln, calendered glass production line and corresponding edging and coating. After the ignition heats up, the project will enter the baking stage. It is expected that the whole line will be connected in the middle and late November, and the finished photovoltaic glass will come out and be sent to photovoltaic module factories such as Trina Solar and Jingao Solar.

It is understood that the project will also build a green integrated intelligent demonstration factory to realize integrated data control of the whole line, and the whole process of the production line will be integrated, linked, intelligent, informational and continuous. The production line is fully compatible with the flexible production of 2.0~4.0mm coated tempered photovoltaic glass, and the technology and finished products are at the international leading level.

The professional technicians of Nanjing Baisheng Glass Technology Co., Ltd. and Nanjing Baisheng Kiln Engineering Co., Ltd. focused on the design and production technology of float glass, flat-drawn (lattice) glass, calendered glass and photovoltaic calendered glass production lines, and carried out bold innovation and transformation from 60t/d to 600t/d, from marten flame and transverse flame furnaces. In recent years, cold repair, baking, thermal insulation and hot repair of large-scale float and rolled glass furnaces are the main projects of the company.

Proprietary technologies of Nanjing Baisheng Glass Technology Co., Ltd. and Nanjing Baisheng Kiln Engineering Co., Ltd.: energy-saving kiln design technology, kiln cold repair breast wall hanging hook brick top replacement, large crown overall lifting and lowering technology, "L" hanging wall design and installation, low-input raw material automatic batching system. The company takes "technology, innovation and service" as its purpose to create value for customers.
