Kentucky Boiler Practice Exam

Which of the following boilers would exceed a pressure of 160 psig?

1. Hot Water Supply Boiler

2. High Pressure/High Temperature Boiler

3. Heat Recovery Boiler

4. Heating Boiler

The correct answer is: High Pressure/High Temperature Boiler

The option that is correct pertains to the classification of boilers based on their operating pressure. A High Pressure/High Temperature Boiler is specifically designed to operate at pressures that exceed 160 psig. These types of boilers are commonly used in industrial applications where high pressure is necessary for efficient operations, such as in power generation, steam production, and other processes requiring substantial thermal energy. In contrast, other types of boilers, such as Hot Water Supply Boilers and Heating Boilers, generally operate at much lower pressures, often below 160 psig, primarily for residential heating and hot water applications. Heat Recovery Boilers can vary in design but typically are not classified to operate at pressures above 160 psig unless specifically designed for high-pressure operations. Hence, understanding the operational characteristics of these various types of boilers clarifies why the selected option is indeed the one that exceeds a pressure of 160 psig.
