A heat recovery system for industrial processes captures waste heat generated during operations, such as from exhaust gases, hot equipment, or cooling systems, and reuses it to improve energy efficiency. Typically, it involves equipment like heat exchangers, recuperators, or regenerators to transfer thermal energy to another medium, such as water, air, or process fluids, for uses like preheating raw materials, generating steam, or space heating. These systems reduce energy consumption, lower operating costs, and decrease greenhouse gas emissions. Common applications include furnaces, boilers, kilns, and power generation plants. Efficiency depends on the system design, temperature differences, and integration with existing processes.
