The core equipment of an MVR steam compressor is the steam compressor itself. Today, the editor will talk about it. MVR steam compressor The working principle.
According to the classification, MVR steam compressor Different—first, the editor will briefly introduce the principle of MVR.
An MVR evaporator uses a steam compressor to compress secondary steam, increasing its temperature and pressure. The resulting high-temperature, high-pressure steam is then sent to the heating chamber inside the evaporator, where it serves as heating steam. The MVR evaporator is highly energy-efficient, enabling full utilization of steam that would otherwise be discarded and significantly improving thermal efficiency.
The steam compressor is the primary and core equipment of the MVR steam compressor. So, what is the working principle of a steam compressor?
A steam compressor is a key piece of equipment in thermal recovery systems, used to increase the temperature and pressure of steam generated through compression. Its function is to heat low-pressure (or low-temperature) steam to meet the temperature and pressure requirements of the process or engineering application.
The overall composition of a steam compressor is relatively complex, consisting primarily of three basic units: the compression system, the steam condenser, and the lubrication system. The steam generated in the boiler (evaporator) passes through a built-in micro-droplet separator to remove some of the liquid content from the steam before entering the steam compressor or the corresponding steam outlet. During process design, an un-compressed steam bypass can be retained to meet varying steam pressure and temperature requirements via automatic control, or to prevent compressor failures.
There are different types of steam compressors, including centrifugal steam compressors and Roots steam compressors; each type has its own distinct applications.

Principle of MVR Steam Compressor
The theoretical basis of MVR is Boyle's Law. This means that PV/T = K, where the product of pressure and volume divided by temperature remains constant for a given mass of gas. Consequently, if the volume of a gas decreases, its pressure increases, and its temperature also rises.
The principle behind the MVR steam compressor is that when dilute secondary steam is compressed, its temperature rises, enabling the conversion of low-temperature, low-pressure steam into high-temperature, high-pressure steam. This high-pressure steam then re-heats the original liquid that needs to be evaporated back to the heat source, thereby achieving the purpose of steam recovery. This compression of steam volume is accomplished by a mechanical compressor, which is why it’s called MVR.
Principle of MVR Steam Compression Technology
The energy-saving principle of MVR evaporators, based on the operating principle of MVR steam compressors, lies in the use of a steam compressor. By replacing fresh steam with electric heating, the system consumes less electricity. The secondary steam generated during evaporation is compressed and fully utilized, resulting in virtually no steam loss throughout the entire evaporation system. The heat from the condensate and concentrated liquid is exchanged with the feed liquid, while non-condensable gases are also exchanged with the feed liquid. The compressor motor employs variable-speed control.
