Heat recovery in plastic or stainless steel

The TVR is designed to extract the warm exhaust air from processes in order to heat cold water with the exhaust air. This preheated water can be reused for the process. However, it is possible to use preheated water to support water heaters and heating systems.

For cleaning systems with aqueous cleaner, pretreatment systems, galvanic systems in hot exhaust air systems of dryers and chimneys.

Heat exchanger assemblies are integrated systems comprising multiple heat exchanger units arranged and interconnected to meet specific thermal management requirements in various industrial processes and applications. These assemblies play a critical role in transferring heat between fluid streams, enabling efficient heat exchange to maintain desired temperatures, improve energy efficiency, and optimize process performance.
Heat exchanger assemblies facilitate the transfer of heat between two or more fluid streams while ensuring the separation of the fluids to prevent mixing. They are designed to accommodate different heat transfer mechanisms, including conduction, convection, and radiation, depending on the application requirements.

Types of Heat Recovery Systems
Waste Heat Recovery Boilers: These systems capture waste heat from exhaust gases produced by industrial processes, combustion engines, or other sources and use it to generate steam or hot water for heating or power generation.
Heat Exchangers: Heat exchangers transfer heat from one fluid stream to another without mixing them. They are commonly used to recover heat from hot fluid streams and transfer it to cooler streams, such as air-to-air heat exchangers or liquid-to-liquid heat exchangers.
Combined Heat and Power (CHP) Systems: Also known as cogeneration systems, CHP systems simultaneously generate electricity and capture waste heat produced during electricity generation for heating or other purposes.
Thermal Energy Storage Systems: These systems store excess heat generated during off-peak periods and release it during peak demand periods for heating or cooling applications.
Heat Pump Systems: Heat pumps extract heat from low-temperature heat sources (such as ambient air, water, or ground) and upgrade it to a higher temperature for space heating or water heating.
Refrigeration Heat Recovery: In refrigeration systems, heat recovery units capture waste heat from the refrigeration process and utilize it for water heating or space heating.

Industrial Processes: Heat recovery systems are widely used in industries such as manufacturing, chemical processing, oil refining, and food processing to recover waste heat from various processes, including furnaces, boilers, kilns, and ovens.
Commercial Buildings: Heat recovery systems are employed in commercial buildings for HVAC (Heating, Ventilation, and Air Conditioning) applications to recover heat from exhaust air and reuse it for space heating or water heating.
Power Generation: In power plants, heat recovery systems capture waste heat from exhaust gases or cooling water and utilize it to generate additional electricity or provide district heating.
Transportation: Waste heat recovery systems are installed in vehicles, ships, and aircraft to capture waste heat from engines and use it for auxiliary power generation or propulsion.

GEWA heat recovery systems
    

• for the heating of heating water or drying air
• best utilization of the heat recovered from the galvanizing furnace thanks to best possible adaptation to the heat requirements of the preliminary treatment baths or the drier
• long life thanks to robust construction
• high degree of economic efficiency and fast amortization
• easy to operate and maintain thanks to apparatus with a well thought-out design

The heat exchanger is designed for selective heat extraction from production systems, such as annealing furnace or bakery ovens and their flues.
If no heat is required from the system, the bypass motor is activated to bypass the heat exchanger.
The heat exchanger can recover enough heat to heat a warehouse or offices within the same building. Even the complete hot water requirement of a building can be provided.
High grade stainless steels
The AWT heat exchanger is manufactured from high-grade stainless steel 1.4571/1.4404, a stainless steel that has been in use in high technology flue gas applications for several years. For high stress applications, a version of the AWT made from 1.4539 is available.
For applications involving extremely high flue gas tempratures. An AWT heat exchanger fabricated in stainless steel 1.4828, which has a high nickel content, can be supplied.
Even retrospective installation of an AWT heat exchanger can be cost-effective, praticularly in times of high energy costs, so that pay-back in two to three years can be achieved.
