How to Use This Calculator
- Enter your target heat output in BTU/hr based on the cooking task.
- Set fuel stick diameter, moisture content, and insulation thickness.
- The calculator outputs chamber cross-section, chimney height, feed tube length, pot gap, and fuel consumption rate.
- Use these dimensions as a blueprint for building the combustion chamber and riser.
- Verify that actual BTU output meets your target and adjust stick diameter if needed.
