Arkansas Boiler Operator Practice Exam

Define "condensate" in the context of boiler operations.

1. Steam that is not fully vaporized

2. Water formed when steam cools and returns to liquid state

3. Liquid water heated to boiling point

4. Air mixed with heated water

The correct answer is: Water formed when steam cools and returns to liquid state

In boiler operations, "condensate" refers specifically to the water that is formed when steam cools and returns to its liquid state. This process occurs when steam produced by the boiler moves through the system, and as it loses heat, it condenses back into water. This is an essential part of steam systems, as the condensate can be collected and returned to the boiler to be reheated, thereby improving the efficiency of the system and conserving water. Understanding this concept is crucial for boiler operators, as managing condensate effectively can enhance energy efficiency and reduce operational costs. Additionally, proper treatment of condensate is necessary to prevent corrosion and fouling in the boiler and piping systems. The other options do not accurately represent the definition of condensate in this context, as they refer to different states of water or mixtures that are not specifically related to the cooling of steam.
