Which one, coal, electricity, or oil, is cheaper for heating aluminum?
Thread Content
Our company produces aluminum powder. If we want to heat aluminum from 800 degrees to 900 degrees, which heating method is the most suitable: gas, electricity, or heavy oil? Please help him.
Using electricity is definitely the most expensive. Personally, I think using oil is better.
Burning coal directly is the cheapest. We need to do some specific calculations as well.
Heated with coal, the coal tar in the pipes is a real headache and difficult to deal with. :lol:handshake
When installing separators in pipelines, it is generally cheaper to use coal. The decision should be based on a variety of factors such as the surrounding environment and location.
Electric power offers the most flexible control, while coal is the most cost-effective option. If the load remains relatively stable, use coal; if the load is unstable, use heavy oil. For small-scale production, electric power is the better choice – the decision should be based on the actual circumstances
Natural gas can also be used; we use natural gas to produce atomized aluminum particles
