Coal & Coke Fuel DemandAnvil Guild
Estimate required fuel weights (kg or lbs) for fire pot hearths based on blast air configuration and active hours.
To complete the designated forging session
Estimated energy content of fuel mass
Hearth Management Advisory
Continuous air blowers maintain a ready forging fire but consume coal during hammering intervals. Use an air gate damper when idling.
