What does the "red zone" indicate in boiler operations?

In boiler operations, the "red zone" refers to the operational area that is close to the design limits of the boiler. Operating in this zone typically indicates high pressures and temperatures that approach or exceed the safe operational thresholds established by the manufacturer. This is significant because it serves as a warning for operators that they should be cautious; entering or operating within this zone can increase the risk of equipment failure or accidents, such as boiler explosions or severe damage to the system.

Understanding the importance of the red zone helps ensure safe operation and maintenance of the boiler system. It is critical for operators to monitor performance closely and take corrective actions if operations approach these limits to avoid hazardous situations.
