Work optimization for rotary regenerative air preheater based on an increase of heat capacity of the matrix and reduction of leakage in seal clearances
Апстракт
The paper shows a reconstruction of rotary regenerative air preheater in purpose of increase of it's energy efficiency. The increase of matrix heat capacity was examined with minimal modifications to geometry of heat exchanger surfaces. At the same time, the influence of lower air leakage through the seals on the efficiency of the plant was also tested. All research were performed for two fuel qualities. From a series of thermal and aerodynamic calculations, the optimal work conditions of rotary regenerator were chosen in terms of energy efficiency of the boiler plant. The shown results were verified by measurings executed at the plant after reconstruction.
