Which components are designed to prevent damage to the sewer system?

The components that are specifically designed to prevent damage to the sewer system are effectively found in the correct answer. A blowdown tank is utilized to safely collect and separate water that has been removed from a boiler system, helping to minimize the introduction of contaminants into the sewer line. The blowdown separator further ensures that any suspended solids or impurities are properly removed from the water before it is discharged, preventing potential clogging and damage to the sewer infrastructure.

The inclusion of a heat exchanger in this context is also critical, as it can help cool down the blowdown water, reducing the thermal shock and subsequent damage that might be caused to the sewer lines when hot water enters the system. Together, these components work to ensure that any discharges are managed safely and effectively, thereby protecting the sewer system from adverse effects.

This understanding of how each component contributes to the overall operation and maintenance of sewer systems highlights the significance of proper equipment in ensuring environmental safety and infrastructure integrity.
