Combustion of Pulverised Coal in a Mixture of Oxygen and Recycled Flue Gas

(4.55)

where $\varphi =\frac{2p+2}{p+2}$ is the oxidiser-to-fuel ratio, indicating the composition of the reaction products, and can take values between 1 (with ${\text{CO}}_2$ being the only product) and 2 (with CO being the only product). The formation of any of these products is often empirically correlated with an Arrhenius equation such as:

$p=\frac{\left[\text{CO}\right]}{\left[{\text{CO}}_2\right]}=A_0{e}^{-B_0/T_p}$ (4.56)
