Hope you all are doing good.
I was reading a book on boilers and burners design and had a problem in understanding some part of the text which I have attached below
post problem 2.JPG
The problem is that I not comprehend the following
1. How unburnt carbon mass can be achieved by subtracting CO2 * 12/44
2. The units of the second picture are not being achieved.
If anyone can help me in this regard, i would be very glad.
Thanks in advance.
