In a steam system, what is regulated by the control valve?

In a steam system, the control valve is primarily responsible for regulating the flow of steam to maintain the desired pressure within the system. The control valve adjusts the amount of steam that enters various components of the system based on feedback from pressure sensors and controllers. By controlling the flow of steam, the valve helps ensure that the system operates within specified parameters, allowing for efficient energy transfer and avoiding situations that could lead to equipment damage or unsafe operating conditions.

While temperature of feedwater, condensate levels, and air quality in the combustion chamber are important aspects of a steam system, they are typically managed by different devices or systems such as feedwater control systems, level sensors, and combustion control systems. Thus, the control valve's primary function is related to steam flow and pressure maintenance, which is essential for the overall efficiency and safety of the steam system operation.
