Effect of using floating ball valves in the black water pipeline of the gasifier
Thread Content
What is the performance of floating ball valves in the black water pipeline of gasification furnaces? Companies with relevant experience are invited to share their insights.
At present, zirconia ceramic floating ball valves are being used in most cases for the black water and gray water generated in coal chemical industries. Zirconia has a high hardness, with a Rockwell hardness of 87; its ball core features high surface finish. Thanks to its self-lubricating properties, the torque required is very low. Currently, companies such as Shenhua, China National Coal Group, and Yankuang are all using zirconia ceramic ball valves
