Full Oxygen Combustion Online

On the morning of March 4th, at 9:00 am, without a ceremony, under the attention of the personnel from Chengmai County in Hainan Province and Hainan Zhonghang Special Glass Company, the glass furnace of Zhonghang Special Glass’s No. 3 production line was ignited.

This marks the first domestically produced full oxygen combustion online low-e energy-saving coated glass production line in China, signifying that China’s float glass technology has reached the highest international level. At the same time, this high-tech glass suitable for energy-efficient buildings is expected to create new opportunities in the provincial and even national construction materials market. With the ignition and production launch of Zhonghang Special Glass’s No. 1, No. 2, and No. 3 lines, and the completion of No. 4 line, which is planned to be ignited later this year, the annual output value of the production base is expected to reach 5 billion yuan, with a tax revenue of approximately 1.2 billion yuan.

According to the introduction, the low-e energy-saving coated glass produced by Zhonghang Special Glass’s No. 3 line, also known as low-emissivity energy-saving coated glass, blocks the conduction of infrared heat when allowing light to pass through the glass. Around 70% of solar heat in buildings enters indoors through glass conduction. However, by using low-e energy-saving coated glass, it can block the outdoor infrared heat from entering indoors during hot summers, and prevent the infrared heat from escaping through the glass during cold winters, resulting in energy savings of 20% to 30%.

In early 2009, Hainan Zhonghang Special Glass Materials Co., Ltd.’s high-end glass production base was officially established in Hainan’s Chengmai Economic Development Zone. The first-phase project of the base had a total investment of 3.2 billion yuan, covering an area of 641 acres, and consisted of four production lines designated as key projects in the province. Among them, the No. 1 line is the transformation project for electronic thin-film glass production line, the No. 2 line is the transformation project for ultra-clear solar TCO glass production line, the No. 3 line is the production line for full oxygen combustion online low-e coated energy-saving glass, and the No. 4 line is the production line for aviation and high-speed rail glass.
