Every good engineer knows that you cannot control what you cannot measure. In the case of rotary regenerative air heaters, many plants fail to limit the negative impact of heater leakage because they use measurement procedures and/or devices that fail to take into account its indirect effects. For a 500 MW coal-fired plant the heat energy that air heaters capture and recycle amounts to about 60% of that existing in the boiler, equivalent to 1.5 Btu per hour. This article explains the importance of accurately measuring leakage levels and the need to use modern seals to make heaters air-tight. 4 figs.
