Which type of moisture separator uses a wax that reacts to temperature changes to operate?

The correct answer relates to the variable orifice type of moisture separator, which operates using a wax material that reacts to temperature changes. In a variable orifice moisture separator, the wax expands or contracts in response to temperature variations, adjusting the size of the orifice through which the steam passes. This allows for a more efficient separation of moisture from the steam because the orifice can dynamically change to maintain optimal performance, depending on the operating conditions.

This reaction to temperature is particularly beneficial in systems with fluctuating loads, as it helps improve the efficiency of steam cycles by ensuring that only dry steam is delivered downstream, thus preventing potential damage to equipment and enhancing overall system reliability. The variable nature of the orifice sets it apart, making it well-suited for applications where moisture content in the steam can differ significantly.

In contrast, other types like fixed orifice moisture separators do not have this adaptive capability; they maintain a constant opening regardless of temperature changes, which can lead to inefficiencies under varying operational conditions. Manual moisture separators require manual intervention to adjust and do not automatically respond to temperature fluctuations, which can result in less optimal moisture removal. Gravity-based separators rely on the principle of gravity to separate moisture but lack the refined control that a variable orifice
