Gasifier Syngas Simulator
Estimate syngas composition, heating value, and engine power potential based on your gasifier type, fuel, and operating conditions. Results use a simplified equilibrium model — treat them as indicative, not design specifications.
Inputs
Mix two fuel species by mass fraction to simulate co-gasification (e.g. charcoal + wood chips).
ER is the ratio of actual air supplied to stoichiometric air. Most gasifiers run 0.25–0.35.
Enter your engine's displacement and RPM to see how well it matches this syngas — including derating, fuel feed rate, and shaft power estimate.
Set your parameters and click Run Simulation to see results.
Multi-fuel comparison
Run all fuels at the same conditions and see how they rank.
About this simulator — work in progress
This tool uses a simplified two-reaction equilibrium model based on the Boudouard reaction and water-gas shift, with fuel properties drawn from the FAO Forestry Paper 72 and FEMA emergency gasifier documentation.
Real gasifiers deviate from equilibrium due to reaction kinetics, channeling, tar formation, and heat losses. Do not use these numbers for engineering design. They are useful for understanding how changes in moisture, fuel type, and equivalence ratio affect syngas quality — not for sizing components or predicting exact output.
Planned additions: pressure drop, char burnout fraction, engine derating factors, and a fuel drying energy calculator.
