Shell & Tube Heat Exchangers for Heavy Oil Heating by Steam

Shell & Tube Heat Exchangers for Heavy Oil Heating by Steam

Shell and tube heat exchangers for steam-heated heavy oils are typically used to heat heavy oils by means of steam, so that their fluidity is increased for further delivery and use, e.g. into oil-fired boilers. This type of system is commonly used in marine engines, paper drying equipment, etc. The main purpose is to increase the availability of fuel.

Principle of operation:

Steam heat transfer: Steam flows through the shell course of the heat exchanger and transfers heat to the heavy oil. The heavy oil then flows through the tube section of the heat exchanger.

Heavy oil fluidity improvement: by heating, the viscosity of the heavy oil is reduced, making it easier to pump and burn.

Areas of application:

Marine engines: Diesel engines on board ships usually require heating of the heavy oil for efficient combustion.

Paper industry: In the process of paper drying, oil-fired boilers generate heat for drying.

Characteristics of heat exchangers:

High Temperature and Pressure Resistance: Steam systems typically operate at higher temperatures and pressures, so heat exchanger materials need to be resistant to high temperatures and corrosion.

Highly efficient heat transfer performance: Shell and tube heat exchangers are able to provide a large heat transfer area while being able to handle viscous media, such as heavy oil.
