Abstract

Based on the standard thermodynamic calculation method of dual-section regenerative air preheater

a heat transfer calculation model of tri-section regenerative air preheater has been deduced

at the sametime

the method for finding solution and the program of thermodynamic calculation being given.The results of practical calculation show that the said thermodynamic calculation method not only has higher precision of calculation

and is easy to calculate

but also can calculated the mean temperature at the interface where the heating surfaces in hot section and cold section intersect.The result of calibriting calculation tallies well with the original designed data.
