1. Overview

The Shell and Tube Heater is a widely used heat exchange device designed to heat process fluids in various industrial systems. It operates on the classic shell-and-tube principle, using steam, hot oil, hot water, or other thermal media as the heating source. This equipment offers reliable, uniform heating and is suitable for high-pressure, high-temperature applications in continuous process industries.

2. Working Principle

In a shell and tube heater:

• The heating medium (e.g., steam, thermal oil) flows through either the shell side or the tube side.

• The process fluid to be heated flows through the opposite side.

• Heat is transferred through the tube walls, raising the temperature of the process fluid to the desired level.

The design can be optimized for counterflow or parallel flow depending on process requirements.

3. Key Features

• High heat transfer efficiency with optimized tube layouts

• Robust mechanical structure suitable for high-temperature and high-pressure operations

• Customizable flow arrangements to suit different heating needs

• Safe and leak-resistant design, supporting critical heating applications

• Adaptable to various heating media including saturated steam, superheated steam, hot water, and thermal oil

• Easy maintenance with options like floating head or U-tube designs

4. Industrial Applications

• Chemical and Petrochemical Industry: Heating of process streams, feedstock preheating, condensate heating

• Oil and Gas Industry: Crude oil heating, condensate stabilization, well fluid conditioning

• Power Plants: Boiler feedwater preheating, condensate recovery systems

• Pharmaceutical and Food Industries: Clean-in-place (CIP) system heating, process fluid heating

• Marine and Offshore: Fuel oil heating, jacket water preheating

• Pulp and Paper, Textile: Process fluid temperature control

5. Design Options

6. Advantages

• Stable temperature control for continuous processes
