What is the difference between low-pressure and high-pressure boilers?

The distinction between low-pressure and high-pressure boilers primarily revolves around the pressure at which they operate. Low-pressure boilers are defined as those that operate at or below 15 psi. This level of pressure is typically suitable for applications such as heating and hot water production in residential and commercial settings, where the demand for steam or hot water does not require higher pressures.

In contrast, high-pressure boilers function at pressures above 15 psi. These types of boilers are often utilized in industrial settings or in processes that require higher steam temperatures and greater energy efficiency, such as power generation or large-scale heating applications.

Understanding this pressure distinction is crucial for compliance with regulations, safety measures, and operational efficiencies associated with different types of boilers. It underlines various operational capabilities, maintenance requirements, and safety considerations based on pressure levels. This knowledge is fundamental for those working in boiler operations, maintenance, and regulatory compliance, particularly within the context of the TDLR (Texas Department of Licensing and Regulation) framework.
