Kentucky Boiler Practice Exam

What does a lined potable water boiler do?

1. Generates steam for industrial use

2. Supplies potable water with a corrosion-resistant lining

3. Stores water at high pressure

4. Is used for heating oils

The correct answer is: Supplies potable water with a corrosion-resistant lining

A lined potable water boiler is specifically designed to supply potable water that is safe for human consumption. The key aspect of this type of boiler is its corrosion-resistant lining, which protects the water from contaminants and ensures that it remains safe to drink. This lining also helps prolong the lifespan of the boiler by preventing rust and deterioration, which are critical considerations when dealing with potable water systems. In contrast, other options focus on different functionalities. Generating steam for industrial use pertains to boilers specifically designed for steam production, often without concerns related to water safety. Storing water at high pressure refers to systems that maintain pressure for various applications but do not necessarily meet potable water standards. Using a boiler for heating oils is a completely different process, focusing on thermal applications rather than providing safe drinking water. Thus, the defining trait of a lined potable water boiler is its role in supplying safe drinking water through its protective lining, making option B the most appropriate answer.
