Regarding water-coal slurry additives
Thread Content
Regarding the issue of water-coal slurry additives, why do the storage tanks used to hold these additives require steam heating? And why do even the additive pumps need steam heating pipelines? Please, someone knowledgeable can help! I’ll give extra points to those who answer correctly. Thank you!
Haha! This question is too simple! (Please don’t get angry, OP! ) In simple terms, it’s for heat tracing to prevent freezing! Prevent additives from freezing in winter!
If it’s placed indoors, isn’t steam tracing then unnecessary?
It is usually heated by steam; without heating, the additives tend to stick together.
Steam tracing for additives is primarily used to prevent the additives from sticking due to low temperatures (as precipitation may occur in the solution, making transport difficult); anti-freezing is merely a reason that is not worth mentioning.
The answer is upstairs. Common additives have high viscosity at room temperature, making them difficult to transport ； As the temperature rises, its viscosity decreases, which facilitates transportation. Many patents for additives claim that they have low viscosity and are easy to transport, but this is mostly commercial marketing. This post was last edited by haichuaner on 2009-3-10 13:15]
It is to prevent the additive solution from freezing due to low winter temperatures； Additionally, substances will precipitate out of the solution.
You are using naphthalene-based additives with a high sodium sulfate content; crystallization occurs at low temperatures, making it difficult to remove them
