Good news has come again from Dongfang Boiler’s Deyang manufacturing facility: on September 27, the methaneation waste heat boiler and steam superheater, which are key components of the Hengli Methanation Project – one of the labor competition projects designated by Dongfang Boiler for 2019 – were completed and shipped. This marks the successful localization of ultra-large-sized Topsoe waste heat boilers, breaking the foreign monopoly; it holds great significance for the development of the company’s chemical container industry. It also signifies the successful conclusion of the special labor competition organized for the Hengli Methanation Project, serving as a valuable contribution to celebrating the 70th anniversary of the founding of the People’s Republic of China.
1. Aesthetic appeal and protective function. 2. Distinctive markings. 3. Special standards specify colors.
It is a special symbol; this principle is actually applied in everyday life as well
The Hengli methanation project utilizes technology from the Danish company Topsoe; the key components of the project include 2 methanation waste heat boilers, as well as 1 steam superheater No. 1 and 2 steam superheaters No. 2. Methanation waste heat boiler units are large in size, with a length of over 19 meters and a total weight of around 310 tons. In the past, such large-scale methanation waste heat boilers had to be imported from abroad. The deep-hole welding of their flexible tube sheets involves a completely new welding technique, which requires high precision and presents great challenges. The No. 1 steam superheater features a bayonet-type heat exchange tube structure; it is the largest Topsoe technology steam superheater in the world today. The manufacturing precision required for these heat exchange tubes is extremely high, the production process is complex, and the equipment is large in size – its length exceeds 21 meters and its total weight is around 390 tons. The production of methanation waste heat boilers and steam superheaters with Topso structure is extremely difficult; Topso has granted manufacturing rights to only two domestic companies, including Dongfang Boiler
Which other company is authorized?
The Hengli Methanation Project is one of the labor competition projects launched by Dongfang Boiler in 2019. The waste boiler components used in this project employ Topso technology and are of large size; the deep-hole welding of their flexible tube sheets constitutes a new welding technique that requires high precision and presents great challenges. Additionally, the 1# steam superheater featuring a bayonet tube structure is the world’s first product designed by Topso; it requires extremely high precision and involves complex manufacturing processes. With these two major obstacles, coupled with the tight delivery deadline requiring manufacturing and shipment by September, the situation is extremely challenging.
