Statistics on pipeline sections prone to wear in water-coal slurry gasification: Please share information on the parts of your installations that are susceptible to wear, so that these can be taken into consideration during project design. Also, what methods are used to eliminate leaks at the worn areas. Which method do you think is the most reasonable and feasible?
In fact, whether it is coal slurry pipelines or black water pipelines, the areas prone to wear are those with high flow rates. The areas with high flow velocities are the elbow sections; therefore, both the coal slurry pipelines and the black water pipelines use elbows with large radii to reduce the flow velocity of the fluid and extend their service life.
High flow velocity is indeed the main cause of pipe wear.
The most wear-prone parts in our facility at present are not in the slag water system, but rather the outlet pipeline of the lock-hopper circulation pump and the circulation pipeline.
Based on my current experience, is it possible that the flow rate of your lock-hopper circulation pump is set too high?
It’s possible; we’re also considering that option. The form of pipe damage is not simply wear, but is accompanied by a honeycomb pattern.
I guess the temperature control for slag discharge in your lock-type mills is quite high!
