🔥 Rotary Kiln Start Sequence, Interlocks and Counter-Current Heat (2D side view)

2D side view of a rotary kiln with twelve zones. Start the burner sequence (precheck, purge, ignition, warmup, run), set target temperature, airflow, rotation and feed, inject faults and watch the safety interlocks trip the fuel. Gas flows against the solids; mass, energy and sequence timing are checked in the page. Same process model and controller as the 3D page.
