This is the 2D-native counterpart to the 3D waste gasification reactor simulator. Rather than orbiting a rendered reactor stack, it draws the two things that actually generate the physics: a schematic zone cross-section (drying, pyrolysis, oxidation, reduction) with waste particles falling through it and syngas bubbles rising out through the offtake, and a live composition-vs-equivalence-ratio chart showing how CO, H₂, CH₄ and CO₂ trade off across the whole ER range at your current temperature and moisture setting, with the current operating point marked. The same engineering-scale gasification model drives both the 3D and 2D versions, so adjusting equivalence ratio, reactor temperature, feed moisture and throughput moves the syngas composition, heating value and cold-gas efficiency identically — just visualised as the schematic and trend data it is, instead of a rendered 3D scene.
