So2 Emission Reduction
Indian coals have low sulfur normally <0.5%. So total SO2 from 4.5 T of coal will not be high. Is there any other source of sulfur? The Calcium Carbonate will be calcined during combustion process. CaO formed will react with SO2.
However a flow sheet with temperatures at various stages will help in understanding your problem. ■
Units Again......
This is a process engineering topic and has no relevance to these forums.
If you post on a relevant competent website they will ask you what you mean by MT.

So2 Emission Reduction
yes Units can be confusing. Lot depends on local usage. MT is metric Tonnes (as we use the term in India for small businesses). It becomes million tonnes only when you are talking about coal mining or large power stations. For a person like me who studied engineering in fifties, it has been an effort to move from ft.lb. and BTU to kg.m and calories. Now I have to change to joules and what not. I have to keep a ready re-conner ready. ■
SO2 Emission Reduction
Our company makes paper as well power(coal based)in a same area. We are burning ETP sludge having 72 % calcium carbonate 10% water & 18% pure fibre in boiler with coal. If we burn 20MT ETP sludge with caol then by putting heat of formation values we can conclude that we can save 4.43 MT of caol per day as we get some amount of heat by burning ETP sludge . Also by doing this so2 emissions are reducing upto some extent because calcium carbonate in sludge reacts with sulphur in coal to form calcium sulphate.
My question is how much sulpher dioxide reduces in a day if we burn 20MT sludge alongwith coal?
Thanking you
