Shrouds are found on which piece of auxiliary equipment?

Shrouds are commonly associated with economizers in auxiliary equipment. Economizers play a crucial role in enhancing the efficiency of boilers or heating systems by preheating the feedwater. They typically utilize the heat from flue gases to increase the temperature of water before it enters the boiler.

In this context, shrouds help to direct the flow of gas and enhance the heat transfer process within the economizer. By directing the flue gas more effectively across the surface area of the heat exchange components, shrouds improve overall thermal efficiency and operational performance, making them integral to the effective functioning of economizers.

The other types of equipment listed, such as condensers, heat exchangers, and reactors, have their own designs and components that may involve insulating or structural elements, but shrouds are specifically characteristic of the function and design of economizers.
