Sichuan National Energy Technology Co., Ltd. was established in September 24 with a registered capital of 1.42 million yuan. The company has Grade B qualification of engineering design and general contracting in power industry (new energy power generation). Relying on the patented technology independently researched and developed, it is specialized in the design of new energy power generation and waste heat utilization (power generation, heating, refrigeration, preheating or drying), general contracting of projects, complete sets of electromechanical equipment and energy-saving and environmental protection technical services. The radiation heat exchange waste heat utilization technology of brick tunnel kiln independently developed by the company has been listed as an alternative technology in the National Key Energy Saving Technology Promotion Catalogue (the fourth batch). In August 211, the company was listed as an energy saving service company (the third batch No.685) by the National Development and Reform Commission and the Ministry of Finance. In 28, Sichuan National Energy Science and Technology Co., Ltd. developed the waste heat power generation technology of coal gangue brick-making (sintering) tunnel kiln, which filled the international and domestic gaps. In May, 29, the tunnel kiln radiation heat exchange waste heat power generation technology developed by the company was selected by the United Nations Development Programme-Spanish Millennium Development Fund/China Climate Change Partnership Framework Project as the demonstration technology of waste heat utilization in tunnel kiln brick making, and two demonstration projects of Shanxi Juyi Industrial Group Xinrong Building Materials Co., Ltd. and Hebei Zhongneng New Materials Co., Ltd. were completed. In October, 211, China Brick and Tile Industry Association held a general election, and the company was elected as the executive director of the sixth Council of China Brick and Tile Industry Association for its influence on energy saving and emission reduction in the brick and tile industry, and won the advanced typical enterprise of China Brick and Tile Industry Association. On July 5th, 212, the radiant heat exchange waste heat power generation technology of tunnel kiln developed by the company won the first prize of the 4th "Jinniu Cup" of China Brick and Tile Industry of China Brick and Tile Industry Association. "Tunnel kiln radiation heat exchange waste heat power generation technology" has obtained the achievement appraisal certificate issued by Sichuan Science and Technology Department, and its main economic and technical indicators have reached the international leading level.
