Heilongjiang Changfeng Coking Co., Ltd., established in 2014, mainly produces coke, tar, crude benzene and other chemical products. The company invested more than 60 million yuan in the second half of 2019 to start a 6 MW coal gas thermal power project, which requires a 45-ton gas boiler and a 6MW condensing steam turbine generator set. Using the by-product coke oven gas produced by the coking plant as fuel, the superheated steam produced by the steam boiler can drive the steam turbine to generate electricity. After it is put into production, the project is expected to generate 60 million kWh of electricity per year, and the heating network can provide 300,000 square meters of heat. It is a key industrial project at the municipal level and is highly valued by the local government. However, this steam boiler has a rated pressure of 3.82Mpa and a steam temperature of 450°C. It is a medium-temperature and medium-pressure Class A boiler, which places higher requirements on the design and manufacture of the boiler.

       On the basis of extensive research and demonstration, the technical department of Taiguo Boiler has customized a ZZ series medium temperature and medium pressure gas superheated steam boiler with domestic leading level for Changfeng Coking. The boiler has an "O" type structure, which has the advantages of compact structure, good furnace flame filling, and small on-site installation workload. Compared with other furnace types, the main engine has a certain cost advantage. In addition, relying on a strong R&D and design team, Taiguo boiler overcomes the design difficulties of medium temperature and medium pressure gas boilers and effectively solves the safety problems of boiler operation. For example, if the structure of the superheater is improperly designed, it is easy to cause fatal problems such as insufficient overheating temperature or overheating, or even pipe burst. Finally, this superheated steam boiler also embodies the advanced production technology and equipment of Taiguo Boiler. Its drum wall thickness is up to 60mm. It is processed by Taiguo Boiler's advanced CNC plate rolling machine and drum drilling equipment, which not only ensures The work efficiency is improved, the smoothness of the drum is improved, and the size difference is effectively reduced. At present, the Changfeng Coking Project has been successfully put into operation, and the boiler is also running smoothly in the project.
