Energy Loss Audit Results

Heat exehange duty Q) and LMTD (ATim) can be ealculated first using equations (6.10) and (6.7) based on online data and then U value is determined using equation (6.1) 

Although major energy losses are addressed as above, other miscellaneous energy losses could occur and some of the examples are  

Energy Input FE MMBtu/b Energy Output FE MMBtu/h 

Heat of reaction 141.0 Energy Lost FE MMBtu/h (above 100 °F) 

Balance check Energy input — Energy output = 819.2 — (77.7 + 741.5) = 0
