What are the two main types of steam boilers?

The two main types of steam boilers are categorized based on their operating pressure, which distinguishes high-pressure boilers from low-pressure boilers. High-pressure boilers are designed to operate over 15 psig, commonly used in power generation and industrial applications, where greater heat and steam generation is required. Low-pressure boilers, on the other hand, operate at 15 psig or below and are typically utilized for heating and sanitation purposes in residential and commercial environments.

Understanding the difference between these two categories is essential for safety, efficiency, and regulatory compliance in boiler applications. Each type has specific design considerations, operational procedures, and maintenance requirements, making this classification significant in the field of boiler operation and management. This knowledge is crucial for boilermakers, as it helps them to select the appropriate boiler type for a specific application, ensuring optimal performance and safety.
