Coal Power Online

Jessica W asked:


Consider a new 38% efficient 600MW power plant burning 9000 Btu/lb coal containing 1% sulfur. If a 70% efficient scrubber is used, what would be the emission rate of sulfur in lb/hr?
any help would be great

Now THIS is a tough question.

surajit r asked:


I want to design a stack i.e. the height, bottom dia, top dia, flange and bolts dia, base plate width etc of a stack. that is why I want a database of any 60 MW power plant

In the US, a very large portion of the electrical power comes from coal. In the short to medium term, there is no way to avoid the combustion of coal.

In the Powder River Basin in Wyoming, abour 500 million tons of the cheapest, cleanest coal in the nation is railed an average of 7-800 miles each year, to feed power plants throughout the midwest and beyond. That requires 100,000 railcars burning in excess of 500 million gallons of diesel fuel, and contributing vastly to greenhouse gases, over and above the burning of the coal itself.

So my question is, what are the physical. engineering factors concerned with the idea that, rather then building coal plants near cities like Chicago or Detroit, we build one or more HUGE plants in the PRB itself, and use high voltage power lines to move the electricity, instead of the coal?

Any ideas?
Thanks, KJ, you let us know when you’ve developed a solution that does not involve coal.
Does anyone have a link that might give some details on the relative power losses in the high voltage long distance power lines used in many countries? In terms of % per mile would be great. Given that we’ve already got a huge network of transmission lines moving power where it is needed, the additioanl losses from the PRB source (again, average <800 mile trip) would strike me as probably less than that 500 million gallons of fuel.

We Test our coal and samples keep coming back great, at the coal yard, On the trucks when leaving, and at the Power Plant and then the coal comes back from the plant lab as bad coal… Multi- testing has been done How,, some with answer of seeking help please advise…

Laursi <3 asked:


Umm how do they work? I thought that they burn coal to produce energy… im prolly way wrong. please help
HAHA i like the last answer. but they both answer what i needed. Thanks heaps =]
oooo another question. whats an alternative way of making energy without producing carbon emissions?

We are about to embark on a long overdue program of building the next generation of nuclear and coal power plants as well as solar and wind power systems.

The problem this poses is the fact that we don’t have enough of the next generation of skilled people in the trades that will be called upon to build and maintain this next layer of our infrastructure.

Conpetency in these skilled crafts isn’t achieved overnight!
