A simple POplant (DI). Fig. 8.18, after Newby et al. [ 121, shows a simple PO plant, of the
type listed as D1 in Table 8. ID. In this plant insufficient air is supplied to the PO reactor,
less than that required for producing stoichiometric combustion. After expansion in the PO
turbine the fuel gas is fed to the main turbine combustor where additional air is also
supplied for complete combustion.
