Steam generator specifications

This paper describes some of the trends in steam generator designs and how engineers should develop specifications for them. Purchasing a steam generator based on “standard” designs available in the form of tabular data or based on “square feet of surface” can lead to a poor selection as is explained. Several aspects such as emissions, steam parameters, special plant requirements can affect the design and configuration of steam generators. A custom designed steam generator is the best choice as it has several advantages over “standard” design. Also, to arrive at the optimum design one has to consider not only the initial costs but also the operating costs. Going by thumb rules or misleading and outdated surface area norm should be avoided
