- Air Preheater Efficiency Calculator Calculate APH gas-side or air-side efficiency based on flue gas and air temperatures.
- Air Preheater (APH) Leakage Rate Calculator Approximates the APH leakage rate using O₂, CO₂, flow rate ratio, or side A/B O₂ comparison. In O₂ and CO₂ methods, the default correction factor is taken as 0.9; users can change this factor if desired.
- Air Preheater X-Ratio Calculator Calculate the APH X-ratio using temperature, no-leakage temperature, or the mass flow method.
- LMTD Calculator Calculate the LMTD value for counter flow, parallel flow, shell-and-tube, and crossflow heat exchangers.
- Generator Stator Air Tightness Test Calculate the stator gas leakage rate using pressure, temperature, volume, and time values.
