本推荐规程（RP）为石油、石化和天然气行业废热回收系统中使用的传热设备提供了指南。只有在确保正确设计和操作以及与热回收系统安全交互所必需的情况下，才包括相关设备设计的详细信息。它指出了需要注意的领域，并提供了各种类型的传热设备的信息和说明，以帮助选择适当的热回收系统。 本RP不包括以下方面的详细要求:-过程间热回收系统，-燃气轮机排气热回收，-CO锅炉，或-燃烧加热器内使用的对流段。本RP中包含的废热回收系统是当前使用的典型系统，不应限制替代系统的使用。有时会提及废热回收系统的仪表和控制装置，但并不意味着完全定义所有要求。应使用其他标准和文件，如API RP 556《火焰加热器的仪表、控制和保护系统》，以充分定义所需的仪表和控制。

This recommended practice (RP) provides guidelines for heat transfer equipment used in waste heat recovery systems in the petroleum, petrochemical and natural gas industries. Details of related equipment designs are included only where these are necessary to ensure proper design and operation and safe interaction with the heat recovery system. It indicates areas that need attention and offers information and descriptions of various types of heat transfer equipment available to aid in the selection of the appropriate heat recovery system.This RP does not include detailed requirements for:- process to process heat recovery systems,- gas turbine exhaust heat recovery,- CO boilers, or- convection sections used within fired heaters.The waste heat recovery systems included in this RP are typical of those currently in use and should not limit the use of alternate systems.Instrumentation and controls for waste heat recovery systems are sometimes mentioned but is not meant to completely define all requirements. Other standards and documents, such as API RP 556, Instrumentation, Control, and Protective Systems for Fired Heaters, should be used to fully define the needed instruments and controls.
