The steam line going to the blowers is connected to the main what?

The steam line going to the blowers is connected to the main steam drum because the steam drum serves as a reservoir for steam generated by the boiler. It is specifically designed to separate steam from water, ensuring the steam supplied to various systems is dry and at the correct pressure. Steam drums distribute steam to different parts of the system, including blowers, where it can be utilized for powering equipment or performing work.

This connection is vital because it allows for efficient steam distribution while maintaining the necessary pressure and quality. Other options, like the condensate return line and the boiler feed line, serve different functions in the steam system. The condensate return line is responsible for returning condensed steam back to the boiler, while the boiler feed line is for introducing water into the boiler to create steam, rather than supplying steam directly to components like blowers.
