Do slurry pipelines tend to accumulate slurry?
Thread Content
The slurry pipelines in our company tend to accumulate slurry, and cleaning them during each shutdown doesn’t remove the buildup completely. I was wondering if everyone’s slurry pipelines also suffer from such accumulation?
Our coal slurry pipelines don’t get clogged very often; generally, given the stability of the coal, there should be no problems for a few hours. Even when we flush the pipelines for up to 7 hours, nothing goes wrong. Please check whether there are any dead zones in your coal slurry pipelines, and ensure that sufficient time is allocated for flushing
It’s more or less the same – high-pressure cleaning! ! !
When designing our product, an inclination angle is included, so it becomes clean after just a few minutes of rinsing
Is the viscosity too high? Slurry tends to clog easily anyway
The quality of coal here is poor; the ash content on a received-base basis is quite high, around 20%!
The ash content is too high; here it’s usually around 6%
The additives are matched to the type of coal used, and sufficient amounts are applied; generally, they do not tend to deposit
It’s not a problem with the additives; the viscosity isn’t high, and the concentration is sufficient!
We do the same; we manage to achieve one-third of that afterwards, and we use high-pressure cleaning every time we park.
