Coal is Too Valuable to Burn! New Coal Liquefaction Technique With No CO2 Emission
Hello sir thank you for this video I wanted to know why is there a coal yard when there is a silo
Why the steam is cooled in the condencer befor it send back to the boiler ? This make it cool , so the energy needed to heat it up is more than if it is hot .
This is the best ever!
كالعادة ، أنت مبدع ، إستمر . As usual, you're creative, keep going .
Another very useful, detailed and yet easy to understand explanation...thanks...👍
It would be cool to see a video in the future on Thrust Bearings and Journal Bearings of various types, and how they typically work with the Hydraulic Oil and Turning Gear systems.
Thank you for all of the videos and all of your hard work. I hope your channel is around for a long time. I've been looking for videos like these for literally YEARS.
Thanks a lot this video is helpful, it's important that you show pictures of the system in reality so We can imagine how it looks like.

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.
Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010
The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008.
In early 2015, it was trading near $56/ton.
