Which of the following is included in the definition of a boiler according to Oregon boiler law?

Boiler fuels and stacks
Only boiler feed piping
Pressure piping only
None of the above

The correct answer is: Boiler fuels and stacks

The definition of a boiler under Oregon boiler law encompasses the entire assembly required for its operation, which includes not just the boiler itself, but also the auxiliary components that contribute to its function. This means that boiler fuels and stacks are integral parts of the boiler system. Boiler fuels are necessary for generating the heat required to produce steam or hot water, while stacks are crucial for the safe exhaust of gases generated during combustion. Including these components highlights the importance of considering the complete system when assessing the safety and efficiency of boiler operations. Understanding this inclusion is essential because it underscores the interconnectedness of the various elements essential to a boiler's function. The other choices, such as only including boiler feed piping or pressure piping, do not represent the holistic view provided by the law regarding what constitutes a boiler system.
