Combustion Efficiency Calculator

Calculate combustion efficiency from stack gas analysis: Siegert method, O₂ concentration, CO₂ concentration. Flue gas loss = q_A + q_B + q_C. Efficiency = 100% - stack losses. Boiler thermal efficiency calculation.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate combustion efficiency from stack gas analysis: Siegert method, O₂ concentration, CO₂ concentration. Flue gas loss = q_A + q_B + q_C. Efficiency = 100% - stack losses. Boiler thermal efficiency calculation

Each component has a specific meaning:

  • Stack gas analysis: Siegert method — The stack gas analysis: siegert method recorded for the patient or scenario being assessed.
  • O₂ concentration — The o₂ concentration recorded for the patient or scenario being assessed.
  • CO₂ concentration — The co₂ concentration recorded for the patient or scenario being assessed.

Note: Interpret the combustion efficiency result against the clinical thresholds and context described above.

How to Use

Enter the stack gas analysis: Siegert method, O₂ concentration, CO₂ concentration for the patient or scenario you are assessing. Calculate combustion efficiency from stack gas analysis: Siegert method, O₂ concentration, CO₂ concentration. Flue gas loss = q_A + q_B + q_C. Efficiency = 100% - stack losses. Boiler thermal efficiency calculation. Use the combustion efficiency result to inform your clinical assessment.
