Improving the corrosion resistance of steel and .

09.02.2017 · The corrosion resistance of structural materials used in coal-tar processing is determined. Besides the water present in the tar, corrosion is accelerated by hydrogen sulfide released in the decomposition of the tar's sulfur- bearing compounds. The corrosiveness of the coal-tar fractions is determined over the height of the distillation column.

Clean Coal Technology related to Coal .

Clean coal technology (CCT), which uses coal in high efficiency and clean, is a key technology to reduce the discharge of the material having high environmental load. Especially since the coal gasification process provides higher energy efficiency in CCT, it is expected to be more widely used for a power generation and chemical raw material production.

Reducing the Impact of Abrasion in Coal .

Coal processing involves transporting coal in various stages as bulk coal is refined into fine particular coal suitable for burning. The impact on equipment can be significant. Ever-persistent abrasion and wear takes a major toll on pulverizers, conveyors, chutes, screws, and other equipment. It can ultimately cause unexpected, costly downtime and/or greatly reduced equipment life.
