Question

Assume you have a coal fired plant that produces 300 MW. The plant is 30% efficient. There is 0.2 lbs. of sulfur produced per BTU. There is 5% residual ash created. Assume you live 4km downstream to the plant. Its is a cloudy summer night with wind of 2.5 m/s. The effective stack height is 100m

1. What is the feed rate of coal to the plant (lbs. per hour)?
2. How much sulfur is produced per hour?
3. What is the concentration of sulfur at your house? - list all assumptions you use
4. Assume the concentration is too high, what should you do?
5. How much ash is produced per day
6. If you have decided to build an ash landfill that can hold 256 years’ worth of ash at the current rate of production, and the coal ash density is 100lbs/cy, how many cubic yards of landfill space must be created?
7. At a cost of $50 per ton of excavation. How much will the landfill excavation cost?

Answer 1

SOLUTION

so here by using the above fact and information provided in the question we can solve it further

sulphur content reaching to our house will be as given below and at a dist of 1 km and depending upon proper stack for vertical flow flume , it is less than 10% of initial value,

and certain precautions and preventions are give below
