Question: 1 / 400

Which type of steam control is activated during pressure increase?

Start

Stop

In the context of steam control systems, the primary function during a pressure increase is to manage and halt the generation of steam or the flow of fuel, thus preventing excessive pressure build-up. This is effectively accomplished by a stop control mechanism, which is designed to reduce or stop the input or production of steam when the pressure exceeds safe operating limits.

Start control typically functions to initiate steam generation when the system is under adequate pressure; it does not play an active role in managing excess pressure situations. Therefore, the stop control is essential during pressure increases, ensuring safety and stability in the boiler operation. This is crucial because exceeding pressure limits can lead to dangerous conditions, such as equipment failure or explosions.
