Recently, the integrated flue-gas purification project with catalytic ceramic fiber filter tubes for the B5 furnace of Yantai Changyu Glass Co., Ltd. (hereinafter referred to as Changyu Glass), undertaken by China National Heavy Machinery Research Institute Co., Ltd. (hereinafter referred to as Sino-heavymach), completed hot commissioning and was officially put into operation. The system ran stably, and the emission concentrations of all pollutants consistently met the specified emission standards.

In view of the characteristics of glass furnace flue gas—such as high dust concentration, high concentration of nitrogen oxides, high temperature, and complex composition—the original electrostatic precipitator was retrofitted into an integrated catalytic ceramic filter system. By integrating high-efficiency particulate removal and denitration into a single unit and combining it with the original dry desulfurization system, synergistic control of sulfur, dust, and  NOx in the flue gas was achieved. The entire flue gas purification system features small footprint, short process flow, high temperature and corrosion resistance, low operating resistance, convenient maintenance and good synergistic emission reduction effect.

This was an environmental protection revamping project characterized by a compact construction site, confined space for equipment layout and a short construction cycle. The project was completed independently through engineering design, manufacture, on-site installation and commissioning. With efficient on-site organization and well‑coordinated working procedures, installation and commissioning were finished and went into operation within only 35 days.

The successful commissioning and operation of the project fully demonstrated the capabilities of Sino-heavymach in design, R&D, and complete-set for the synergistic treatment of multiple pollutants in flue gas. It provided solid support for Sino-heavymach to further expand the market of complex flue gas synergistic treatment and advance the green and low-carbon transformation of the industry.
