en.Wedoany.com Reported - Taiyuan Heavy Industry (TYHI) has successfully won the bid for the ash lock equipment supporting the gasifier of a coal-to-synthetic natural gas project. The gasifier used in this project features a furnace body diameter of 5 meters, making it the largest crushed coal pressurized gasifier in China. The ash lock that TYHI Binhai Company has won the bid for is precisely the key supporting component of this nationally largest gasifier.
The ash lock is a critical component in the gasification system of the gasifier, responsible for collecting high-temperature ash slag, isolating the high pressure inside the furnace from the external atmospheric pressure environment, discharging slag in an orderly manner, and preventing coal gas leakage. Its operational stability directly affects whether the gasifier can operate continuously and efficiently. At the same time, it imposes high requirements on manufacturing precision, material performance, and process level, making it a recognized high-difficulty core equipment in the coal chemical industry.
The ash lock supplied this time is approximately 4 meters wide and 4.9 meters high, currently the largest specification ash lock in China, with a correspondingly significant increase in manufacturing difficulty. The design pressure has been raised from the conventional 4.6 MPa to 5.1 MPa, and the wall thickness has increased from the previous 75 mm to 100 mm. The higher pressure and thicker tank wall impose stricter requirements on production processes such as welding and heat treatment.
To address the project's challenges, TYHI Binhai Company has established a dedicated R&D and manufacturing team, focusing on overcoming core technical difficulties such as precision assembly and welding deformation control, and formulating systematic solutions. Leveraging its long-term technical accumulation, the company has supplied ash lock equipment for over a hundred similar gasifiers in China, which have operated stably and reliably, earning market and user recognition. The user stated that TYHI has deep expertise in the pressure vessel manufacturing field, with solid project performance and rich practical experience. When it comes to building the largest in the country, TYHI is the most reliable choice.
This bid win marks another significant breakthrough for TYHI Binhai Company in the high-end equipment sector of the coal chemical industry.
