“Fired pressure vessels” refer to a category of pressure vessels that are exposed directly to the combustion process or to hot flue gases. In other words, these are vessels where the heating medium is the direct product of combustion, rather than being indirectly heated using a secondary medium.
Fired pressure vessels are subject to rigorous design and operational standards due to the combination of high temperatures and pressures involved. This also means they are susceptible to unique challenges and failure modes not necessarily seen in other types of pressure vessels. For example:
Because of these risks, regular inspection, maintenance, and adherence to operational guidelines are especially important for fired pressure vessels. Design and manufacturing codes, such as the ASME Boiler and Pressure Vessel Code (BPVC), provide standards and guidelines to ensure the safe operation of these vessels.
Given the challenging environment within fired pressure vessels—characterized by high temperatures, cyclic thermal stresses, and potentially corrosive combustion byproducts—the choice of material is paramount. Steels suited for high-temperature service, sometimes with special coatings or treatments to resist specific corrosive elements, are commonly employed.
Given the risks associated with fired pressure vessels, they are typically equipped with a variety of safety devices:
Regular inspection of fired pressure vessels is not just a good practice—it’s often mandated by regulatory bodies. These inspections check for:
Modern fired pressure vessels, especially in industrial applications, are often paired with emission control systems to minimize the release of pollutants. These can include:
In conclusion, while fired pressure vessels play a pivotal role in many industries, their operation and maintenance demand a deep understanding of the associated challenges and risks. With rigorous design, inspection, and operational standards, these vessels can be operated safely and efficiently, delivering value while minimizing potential hazards.
