Air Preheater Analysis

Tale Of The Tool
This tool calculates the leakage percentage in a regenerative air heater and estimates the economic impact of its bypassed air relative to the manufacturer’s specified leakage rate. By doing so, the unavoidable operational cost inherent to the unit’s design is not unfairly assessed against its performance.

Additionally, the tool assesses the cost of any decline in heater effectiveness and estimates the potential load restriction resulting from reduced fan combustion capacity associated with the leakage. When combined, the leakage and effectiveness losses provide a comprehensive view of the air heater’s total economic impact on a plant's performance.
