Abstract
A heat recovery system includes an upstream superheater section and a duct burner arranged to provide improved performance. The upstream superheater section and duct burner are arranged to reduce the negative effects of heat extraction by the upstream superheater section on the duct burner operation. The arrangement provides a downstream flow from the upstream SH section that is temperature stratified and positions the duct burner elements in the areas of maximum temperature. The tubes of the upstream superheater section and the duct burner elements are arranged in a variety of ways to provide temperature stratification, for example, in the horizontal or vertical directions.
