In this tabulation, the factors in column 3 are constants used for computing
the total moles of air required for complete combustion of each of the fuel

elements listed. These factors are given in the Babcock & Wilcox Company
—Steam: Its Generation and Use and similar treatises on fuels and their
combustion. A tabulation of these factors is given in Table 3.

TABLE 3 Molal Conversion Factors

An alternative, and simpler, way of computing the moles of air required is
to convert the required O to the corresponding N and find the sum of the O 2
2
2
and N . Or, 376O = N ; N + O = moles of air required. The factor 3.76

converts the required O to the corresponding N . These two relations were

used to convert the 0.158 mol of O in the above tabulation to moles of air.

Using the same relations and the moles of O required from step 2, we get
