What purpose do stack rain gutters serve?

• A. To reduce evaporation
• B. To allow proper draining of the stack
• C. To regulate flue gas temperature
• D. To enhance airflow

Answer: (B)

Stack rain gutters play a crucial role in the design and operation of a stack by facilitating proper drainage of rainwater that may accumulate on the exterior surface. When rainwater collects at the top of a stack, it can lead to numerous issues, including corrosion and structural integrity concerns if not managed properly. The gutters collect this water and direct it away from the stack and its components, ensuring that any excess moisture does not interfere with the stack's functionality or the equipment connected to it. This drainage is essential for maintaining the longevity and effectiveness of the stack system. The other options, while relevant to different aspects of stack operation, do not accurately represent the primary function of stack rain gutters. For instance, reducing evaporation relates more to heat and moisture management within a system than to rainwater drainage, and regulating flue gas temperature is typically handled through insulation and operational controls, not gutters. Enhancing airflow is also unrelated to the function of rain gutters, as their purpose is strictly related to managing water drainage rather than influencing the movement of gases.
