Online APH efficiency calculator

 

The efficiency of the APH are calculated from two ways one is from air side other from gas side.

APH gas side efficiency

ηAPHg = (Flue gas inlet temp.Tfi-Flue gas outlet temp.Tfo) X 100 / (Flue gas inlet temperature tfi-Air inlet temperature Tai)

APH air side efficiency

ηAPHa = (Air outlet temp.Tao-Air inlet temp.Tao)) X 100 / (Flue gas inlet temperature tfi-Air inlet temperature Tai)

 

Calculate the APH gas side & air efficiency if its flue gas inlet and out let temperature are 245 deg C and 155 deg C and air inlet and out let temperatures are 32 deg C & 173 deg C respectively.

APH Gas side efficiency calculation

ηAPHg = (Flue gas inlet temp.Tfi-Flue gas outlet temp.Tfo) X 100 / (Flue gas inlet temperature tfi-Air inlet temperature Tai)

 ηAPHg =(245-155) X 100 / (245-32)

ηAPHg = 42.25%

APH Air side efficiency calculation

ηAPHa = (Air outlet temp.Tao-Air inlet temp.Tao)) X 100 / (Flue gas inlet temperature tfi-Air inlet temperature Tai)

 ηAPHa = (173-32) X 100 / (245-32)

ηAPHa = 66.19%
