Saturated steam is a powerful tool in industrial and domestic heating systems. Knowing its properties helps to optimize thermal processes, select the right heat exchanger and reduce costs. In this article, we take a closer look at how to use saturated steam data to select the ideal equipment.
What is saturated steam?
Saturated vapor is formed when water evaporates at constant pressure and temperature. Its unique properties, such as high heat of vaporization, make it indispensable for heat transfer.
Key features:
- Boiling (condensing) point: pressure dependent.
- Latent heat of vaporization: energy required to turn water into vapor.
- Density: determines the volume of vapor per unit mass.
- Pressure: affects the operating parameters of systems.
Due to its physical properties, saturated steam is a key element in heat supply and energy exchange systems. Its efficient use ensures the optimization of thermal processes, making it indispensable for industrial and domestic applications. Understanding these characteristics allows you to select equipment that will ensure stable and economical operation of your systems.
Properties of saturated vapor
The following are the basic properties of saturated water vapor at various pressures.
| Absolute pressure, bar | Steam temperature, °C | Specific volume, m³/kg | Vapor density, kg/m³ | Latent heat of vaporization, kcal/kg |
| 0,02 | 17,5 | 67,01 | 0,01492 | 587,6 |
| 0,5 | 81,3 | 3,24 | 0,3086 | 550,7 |
| 3 | 133,5 | 0,6056 | 1,651 | 516,7 |
| 10 | 179,9 | 0,1943 | 5,147 | 481,0 |
| 100 | 311 | 0,01804 | 55,43 | 315,2 |

Why is saturated steam important for heat exchangers?
Saturated steam is widely used in heat exchangers to heat, cool or utilize heat energy. The properties of the steam determine the choice of materials, type and design of the heat exchanger.
How it works:
- Heat is transferred through heat exchanger plates or tubes.
- The properties of steam ensure efficient heat transfer while minimizing losses.
- The right heat exchanger optimizes this process, saving time and money.
Efficient use of saturated steam in heat exchangers can not only significantly reduce energy costs, but also increase system performance. The choice of a quality heat exchanger, taking into account the properties of steam, will ensure stable and durable operation of the equipment, optimizing thermal processes in any industry.
How do I select a heat exchanger to handle saturated steam?
Heat exchanger selection is based on steam properties, operating conditions and system objectives.
Key Criteria:
- Pressure and temperature: Determine choice of materials (stainless steel, copper).
- Steam Volume: Affects the size and performance of the heat exchanger.
- System type: Open or closed systems determine the need for collapsible or brazed models.
Types of heat exchangers for steam operation
| Type | Features | Scope of application |
| Collapsible plate | High efficiency, easy maintenance. | Heating systems, food industry. |
| Brazed plate | Compact, high temperature and pressure resistant. | Air conditioning, refrigeration units. |
| Tubular | Reliable for handling aggressive media. | Oil and gas industry, energy sector. |
Selecting the right saturated steam heat exchanger is key to optimizing thermal processes and reducing costs. By focusing on the basic criteria – pressure, temperature, steam volume and system type – you can ensure efficient and stable operation of your equipment.

Case Study: Calculation of a heating system
Task:
We need to select a heat exchanger for a system that operates with steam at a pressure of 3 bar.
Solution:
- Vapor properties (from the table):
Temperature: 133.5 °C.
Latent heat of vaporization: 516.7 kcal/kg. - Formula for calculating heat output:
Q = G × (hvapor – hpidina),
where Q is the transferred heat, G is the steam flow rate. - Result:
The data obtained allows the selection of a compact brazed plate heat exchanger that will provide maximum efficiency and minimum cost. It is also possible to use a collapsible plate heat exchanger with pressures up to 5 bar, using the required ducts.
