What is a significant concern regarding the performance of steam boilers?

Control of high-pressure steam is a significant concern regarding the performance of steam boilers because high pressure can lead to numerous operational and safety challenges. When steam is generated at high pressures, the risks of system failures and accidents also increase. High-pressure steam systems require precise control to maintain safe operating parameters and prevent incidents such as equipment failure, pressure relief valve malfunction, and boiler explosions.

Maintaining high pressure necessitates advanced control systems and regular monitoring to ensure safety and efficiency. A failure in controlling the steam pressure can not only compromise the boiler's reliability but can also pose serious safety hazards to personnel and the facility.

In contrast, while low-temperature operation, frequent fuel changes, and limited water availability can present challenges, they are generally not as critical as managing high-pressure steam. Low-temperature operation might impact efficiency, but it doesn't typically carry the same level of risk; fuel changes can cause fluctuations in performance but are manageable with proper procedures; and limited water availability can affect boiler performance but can often be addressed with proper water treatment and feed systems.
