Method for Quantifying Heat Duty Derating Due to Interpass Leakage in Bolted Flat Cover Heat Exchanger
TLDR
In this paper, a simplified structural model of the channel cover is constructed to determine the interpass leakage due to cover deflection under pressurized (operating) conditions, and a numerical example shows that design rules based on stress limits are adequate to keep inter-pass leakage within tolerable limits.Abstract:
Functional relations are derived to determine the reduction in the heat duty of a multipass heat exchanger due to tube-side fluid bypass. A simplified structural model of the channel cover is constructed to determine the interpass leakage due to cover deflection under pressurized (operating) conditions. A numerical example shows that design rules based on stress limits are adequate to keep interpass leakage within tolerable limits.read more
