In boiler systems, the feedwater is typically introduced into the boiler through the mud drum. The mud drum is designed as a collection point for water and solids that settle out of the water as it circulates through the system. Introducing feedwater into the mud drum allows for effective mixing and helps ensure that the water is preheated before it flows into the steam-generating sections of the boiler.

The mud drum plays a critical role in maintaining water quality and preventing impurities from being carried into the boiler’s steam space, which could lead to scaling or other issues. By initially feeding water into this part of the boiler, operators can help manage the concentration of dissolved solids and provide a more stable environment for the generation of steam.

The other options do not serve the primary purpose of introducing feedwater into the boiler efficiently or effectively. For instance, introducing water directly into the steam space could result in improper steam generation and operational inefficiency. Similarly, the risers are involved in the natural circulation of water and steam and are not appropriate points for initial feedwater introduction. Lastly, while the economizer is used to preheat the feedwater before it enters the boiler, it is not where the feedwater is introduced; rather, it collects from the mud drum before
