Large all-welded corrugated board air preheating device fills the domestic gap

The National Science and Technology Research Project Guided Project undertaken by Lanzhou Petroleum Machinery Research Institute and other projects - "Key Technology Research on Large-scale All-welded Corrugated Board Air Preheating Device", recently passed the results appraisal in Beijing. After testing, the device is only from flue gas. In the case of medium heat recovery, it can save 5.86 million cubic meters of natural gas per year, equivalent to 6.74 million yuan of fuel gas.
It is understood that the large-scale all-welded corrugated board air preheating device developed by the Lanzhou Petroleum Machinery Research Institute and other units is jointly developed by Lanzhou Petroleum Machinery Research Institute, Sichuan Haotian Chemical Co., Ltd. and Lanzhou Heat Transfer and Energy Saving Engineering Technology Research Center. developing. Entrusted by the Ministry of Science and Technology, the Science and Technology Department of Gansu Province organized domestic experts to identify the device in Beijing. Academician of the Chinese Academy of Sciences and Professor Wang Buxuan of the Department of Thermal Engineering of Tsinghua University served as the chairman of the appraisal committee. The appraisal committee believes that the successful development of the device has filled the domestic gap, has independent intellectual property rights, and ended the history of dependence on imports of similar products, and its overall technology has reached the international advanced level.
