3 main types of Heat Exchangers
These heat exchangers pass cold or heated fluid through a tube bundle enclosed in a huge metal shell. The counter-flowing gas or fluid, which is either hot or cold, is pumped into the metal shell, where the heat transfer takes place.
Applications of shell and tube heat exchangers
Shell and tube heat exchangers have mostly been used in high-pressure applications as well as vacuum conditions that require high stresses. The nature of containment of shell and tube heat exchangers makes them suitable for use in applications that may require containment of noxious, dangerous, or deadly gases. Industries that use shell and tube heat exchangers in their daily operations include:
- Chemical industries
- Gas industries
- Oil industries
A finned tube heat exchanger works by allowing hot liquid fluid to flow through a series of tubes. As the liquid flows into the tube system, the heat exchanger pumps air around the tubes to cool down the liquid. There are finned tube exchangers enclosed in a duct system, while others are exposed such that air flows over them easily. The efficiency of a finned tube heat exchanger is determined by the extended surface of the fins, which influence the ability of heat transfer of the structure.
Applications of finned tube heat exchangers
Finned tube heat exchangers are used in processes that involve the exhaustion of hot gases in heat recovery procedures. The heat in the gas is transmitted into a liquid, such as thermal oil or water. In turn, the hot liquid is used in an application that would otherwise require more energy to heat the liquid. Finned tube heat exchangers are ideal for the following applications:
- Concrete curing
- Steam cooling
- Chemical applications
- Paper manufacture
- Food processing
- Grain drying
- Textile processing
- Petrochemical cooling
Gasket plate heat exchangers function by passing fluids (gas or liquid) through several plates compacted together side by side.
Applications of gasket plate heat exchangers
The gasket plate heat exchangers are found in liquid to liquid applications e.g. hot process water containing contaminants heating the cold water from the mains to produce clean hot water for domestic and industrial use.
Applications that require oils to be cooled using water because the fluids cannot mix mostly use gasket plate heat exchangers to achieve this.
Common Problems With Heat Exchangers
Various problems could arise when using heat exchangers.
Corrosion and rust
Excess condensation may occur inside the furnace, causing corrosion and rust in the components. High-efficiency condensing furnaces usually encounter this problem. If not, the condensate is expelled via the built-in drainage system. However, if the drain line is blocked, the condensation will not flow out well, gradually rusting out the heat exchanger.
Under stressful conditions, metal fatigue can occur, leading to premature metal failure. This may result in a costly replacement of the machine sooner than expected. The most common underlying cause for premature metal failure is insufficient airflow in the heat exchanger system or irregularities in the burner.
Deterioration caused by age
Heat exchangers are designed to withstand extended repeated cycles of cooling and heating. As the heat exchanger ages, the constant contraction and expansion weaken the metal.
What to do With a Faulty Heat Exchanger
