This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the discussions on this forum. ********************************************* On February 20, 2023, the 3,000-ton multi-nozzle opposed water-coal slurry gasification (OMB) furnace manufactured by Dongfang Boiler Co., Ltd. was successfully completed and shipped to Lunan Chemical Company of Shandong Energy Group. It is reported that this gasifier was developed through joint innovation by Dongfang Boiler, Yankuang Lunan Chemical, and East China University of Science and Technology. It serves as the core equipment in Lunan Chemical’s integrated energy-saving and carbon-reduction project for the caprolactam production chain, and it is also the most advanced gasifier of its type in the world, capable of handling a large volume of coal per day. This gasification furnace incorporates a number of industry-first new technologies, enabling successful one-time welding during the welding process at key areas. This gasifier is capable of handling 3,000 tons of coal per day. Compared with existing coal-water slurry gasification technologies, it achieves a carbon conversion rate that is over 10% higher. It offers advantages such as wide compatibility with different types of coal, low consumption, and ease of scaling up, thereby enabling further improvement in coal utilization and reduction of carbon emissions.
Its development is one of the significant advancements in chemical processing equipment over the past decade. The OMB gasifier features excellent energy efficiency and effectively reduces emissions of flue gases, resin, and particulates, making it an effective technology for environmental protection and clean production today. At the same time, this technology also brings higher reliability, lower investment costs and higher production efficiency, as well as a longer service life. The 856-2023-3000-ton class multi-nozzle opposed gasifier boasts several advantages: although it enables the highest thermal efficiency, it can effectively suppress flue gas emissions ； The multi-flame injection technique can effectively suppress uneven airflow speeds, thereby achieving uniform airflow speeds ； Speed and pressure control technologies can be employed to achieve a more optimal and efficient combustion. Furthermore, the multi-flame injection technique can effectively improve the heat efficiency of mixing within the burner, enabling more efficient use of energy and reducing dust emissions, thereby achieving better environmental benefits. -
It is reported that the 3,000-ton-class OMB multi-nozzle opposed coal gasification furnace is the core equipment in Lunan Chemical’s integrated energy-saving and carbon-reduction project for its caprolactam production chain. It enables a carbon conversion rate that is over 10% higher than that of existing water-coal slurry gasification technologies, and boasts technical advantages such as wide adaptability to different types of coal, low consumption, and ease of scaling up, all of which help to further improve coal utilization efficiency and reduce carbon emissions. During the implementation period of this project, Shanneng Chemical Lu’nan Chemical Co., Ltd. worked closely with Dongfang Boiler, East China University of Science and Technology, and Tianchen Design Institute. By coordinating resources from all parties involved, they established specialized teams for technical problem-solving and project management. Overcoming numerous difficulties, they managed to keep up with the scheduled milestones and delivered the project on time.
