Minnesota Special Engineer Boiler License Practice Exam

Question: 1 / 400

What is the typical maximum pressure for a low-pressure boiler?

15 psi

The typical maximum pressure for a low-pressure boiler is 15 psi, which is a standard threshold used in the industry. Low-pressure boilers are designed to operate at pressures that typically do not exceed this limit. This is significant for safety and operational efficiency, as low-pressure boilers are often used in residential heating systems, small commercial applications, and process heating where elevated pressures are not necessary.

In terms of regulatory and operational classifications, low-pressure boilers are defined by the American Society of Mechanical Engineers (ASME) and the National Board of Boiler and Pressure Vessel Inspectors, which both recognize 15 psi as the upper limit for this category. Understanding these classifications is critical for ensuring compliance with safety regulations and proper functioning of boiler systems, which is essential for any operator holding a boiler license.
