What is a characteristic of a High Pressure/High Temperature Boiler?

1. Operates below 150 psig

2. Uses external heat sources

3. Operates at temperatures above 250 F

4. Circulates hot water

The correct answer is: Operates at temperatures above 250 F

A High Pressure/High Temperature Boiler is defined by its ability to operate at elevated pressures and temperatures, which is crucial for certain industrial and energy applications. The characteristic that accurately describes such a boiler is its operation at temperatures above 250°F. This signifies that the boiler is designed to handle the thermal stresses and efficiency requirements associated with higher temperature operations, which typically involves steam generation at pressures exceeding 15 psig and temperatures well above the boiling point of water at atmospheric pressure. The significance of operating above this temperature is multifaceted. It allows for increased energy efficiency and improved heating capabilities. Such conditions are often necessary in processes that require saturation steam or high-quality steam for industrial uses, such as in power generation, food processing, and chemical manufacturing. While the other options present certain scenarios related to boilers, they do not align with the specific features of a High Pressure/High Temperature Boiler, which is centered around its operational parameters of high temperature and pressure.
