Reply For Coal Consumption Rate Per MW

And the question is what, exactly?

Thanks rsn1.

Are you trying to tell us as information or what are you asking?

The consumption of coal depends on the claorific value of the coal, the efficiency of the boiler itself and the lossses in your steam distribution system.

Understood.

Here is my original request for Info:"

Anyone know of reliable source where I could find actual achieved megawatts to the grid per ton of coal combusted? Amount of kilowatt hours to mine a ton of steam coal? Amount of tons per hour mined?Efficiency factors for the conversion? I'm in North America, but confirmed engineering quality experiential factors from other installations globally will be helpful.

If there are underlying assumptions regarding factors of coal, process etc. please share.

Thanks to all."

I'm trying to determine the tngible deferred by a megawatt of noncombustion power vs traditional combustion power-tons of coal Not mined, Oil not consumed in mining etc.

Looking for engineering quality factors.

Now Understood. Actually i was confused as to whose thread this actually is.

By the way, do you have your :

1 . actual achieved megawatts to the grid per ton of coal combusted.

2 . Amount of kilowatt hours to mine a ton of steam coal.

3 .Amount of tons per hour mined?Efficiency factors for the conversion.

4 . Calorific value of your coal, ash & moisture %.

5 . Cost/Ton Coal.

6 . Operating Pressure of your Power Boiler(s) & Efficiency.

7 . Steam Turbine MW generation & Efficiency.

I think the CR4 software bumped my original query and replaced it with that response. I thought that that happened on a what does cr 4 stand for post as well.

I just wanted to get some ball park figure to be able to calculate "offsets" based on replacement of coal fueled electricity.

Thanks
