Download citation file:
This chapter describes shell-and-tube and plate and frame types of power plant heat exchangers and tubular closed feedwater heaters and the language that applies to them. The chapter briefly discusses Header Type Feedwater Heaters and their application and use. It defines the design point used to establish exchanger surface and suggests suitable exchanger configurations for various design-point conditions and the criteria used to measure performance. It does not cover power plant main and auxiliary steam surface condensers because of the differences in how they are designed and operated The chapter briefly discusses the effects on the exchanger of normal and abnormal deviations from design point during operation.
