Data from a test on a NAPOCOR boiler, using pulverized coal, are as follows: Proximate Analysis of Coal Ultimate Analysis of Coal W = 2.80 % C = 84.36 % N = 0.63 % VCM = 1.16 % H = 1.89 % S = 0.89 % FC = 88.21 % O = 4.40 % A = 7.83 % The coal rate is 11762 kg/hr and the excess air required is 35 %. Determine: the “as fired” coal analysis, and the “dry” coal analysis the actual air required per hour.

Question
Data from a test on a NAPOCOR boiler, using pulverized coal, are as follows:
| Proximate Analysis of Coal | Ultimate Analysis of Coal | |
| W = 2.80 % | C = 84.36 % | N = 0.63 % |
| VCM = 1.16 % | H = 1.89 % | S = 0.89 % |
| FC = 88.21 % | O = 4.40 % | A = 7.83 % |
The coal rate is 11762 kg/hr and the excess air required is 35 %. Determine:
- the “as fired” coal analysis, and the “dry” coal analysis
- the actual air required per hour.
