Weight of Fuel ($FCR$):

$$FCR = \frac{Qa}{\xi_g \cdot HVf}$$

Where:

• $FCR$ is the weight of fuel, in kilograms per hour (kg/hr).
• $Qa$ is the actual heat required, in kilocalories per hour (kCal/hr).
• $\xi_g$ is the efficiency of the gasifier, as a decimal.
• $HVf$ is the heating value of the fuel, in kilocalories per kilogram (kCal/kg).
