Recuperator

A recuperator is a device or system designed to recover waste heat from a process and transfer it to another, usually for preheating incoming air or fluids, thereby improving energy efficiency. They are commonly used in industrial settings, furnaces, and heat engines, where exhaust gases contain significant amounts of thermal energy. The primary function is to reduce energy consumption and lower operating costs by maximizing heat transfer. Recuperators often employ heat exchangers to separate the hot and cold fluids, preventing mixing and contamination. Their design depends on the specific application, but they generally involve a series of tubes, plates, or other surfaces to facilitate heat transfer between the fluids.

Recuperator meaning with examples

• The steel mill implemented a sophisticated recuperator system to capture waste heat from its furnaces. This greatly improved the efficiency of the heating process and substantially reduced their reliance on fossil fuels. They now save thousands of dollars monthly on energy costs, thanks to the investment in this crucial technology. Workers are trained to inspect the recuperator regularly.
• In this experimental aircraft engine, a highly efficient recuperator was incorporated to preheat the incoming air. This allowed for a significant increase in combustion efficiency and improved fuel economy. Engineering teams are currently testing the material's resistance to extreme temperatures. The aircraft's flight range was extended due to the recuperator.
• The design of the new industrial dryer includes a recuperator to capture the heat generated by the drying process. This recovered heat is then used to preheat the incoming fresh air, optimizing drying efficiency. The goal is to reduce energy consumption and contribute to a greener operation. Maintenance schedules include regular recuperator cleaning.
• The building's heating system includes a recuperator that transfers heat from the exhaust air to the incoming fresh air. This drastically reduces the building's heating costs, and improves overall energy efficiency. This has significantly reduced the building's carbon footprint as well. Regular air quality tests monitor the recuperator's performance.
