How does an injector function within a steam system?

In a steam system, an injector plays a crucial role by forcing water into a boiler. This process is essential for maintaining the water level needed for efficient steam production. The injector utilizes either steam or the momentum of the water being injected to achieve this forceful movement. When properly operated, it creates a vacuum or uses the pressure differential to draw water from a lower source and inject it into the boiler at a higher pressure. This is particularly important in systems where maintaining proper water levels is critical for safe and efficient operations.

The function of forcing water into the boiler ensures that there is always an adequate supply of water available to generate steam, which is necessary for various thermal applications. It is significantly more efficient than other methods of feeding water into the boiler, as it can do so without relying solely on external pumps, simplifying the system's design and operation.
