Introduction

A steam condenser is a vital heat exchange equipment widely used in power plants, chemical plants, metallurgy, and coking industries. Its primary function is to condense exhaust steam from steam turbines into water, maintaining vacuum inside the turbine and enabling efficient recycling of condensate back to the boiler. By lowering exhaust pressure, the condenser significantly improves the thermal efficiency of the power generation cycle.

Working Principle

The condenser operates on the principle of indirect heat exchange:

• Steam side (shell side): Low-pressure steam enters the condenser shell and comes into contact with the external surface of the cooling tubes.

• Cooling water side (tube side): Circulating cooling water or seawater flows inside the tubes, absorbing heat from the condensing steam.

• Condensate recovery: As the steam condenses into hot water (condensate), it is collected and pumped back to the boiler, ensuring a closed-loop system.

• Vacuum creation: The condensation process reduces steam volume sharply, generating vacuum, which enhances steam turbine efficiency.

Structural Features

1. Shell and Tube Design – The condenser typically adopts a horizontal shell and tube structure, providing large heat transfer surface area.

2. Tube Bundles – Heat exchange tubes made of carbon steel, stainless steel (304, 316), copper alloys, or titanium, depending on water quality and working conditions.

3. Water Chambers – Designs include fixed tube sheet, floating head, or U-tube type, allowing for thermal expansion and convenient maintenance.

4. Auxiliary Systems – Equipped with air extraction, venting, and water treatment devices to ensure stable vacuum operation.

Applications

• Power Plants – As a steam turbine condenser, converting turbine exhaust steam into water and ensuring continuous circulation.

• Chemical Industry – Used as a process condenser for steam condensation, solvent recovery, and cooling operations.
