Calculation of theoretical air demand (V₀)

For solid fuels:

When the fuel application base will score V_y >15% (bituminous coal), the calculation formula is:

\( V_0=0.251 \times Q_L/1000+0.278 \) m³(standard)/kg

When V_y <15% (lean or anthracite), the formula is:

\( V_0=Q_L/4140+0.606 \) m³(standard)/kg

When Q_L <12546kJ/kg (low quality coal), the formula is:

\( V_0=Q_L/4140+0.455 \) m³(standard)/kg

In the formula:

V₀—the amount of theoretical air required for fuel combustion, m³(standard)/kg or m³/m^3;

Q_L—the fuel application base low calorific value, kJ/kg or kJ/(standard) m³.
