Process heat refers to the thermal energy used in industrial processes to produce goods or facilitate operations. This heat is essential for various applications, such as heating, melting, drying, and chemical reactions. Industries like manufacturing, food processing, and petrochemicals rely on process heat to maintain efficiency and product quality. Sources of process heat can include natural gas, electricity, steam, and renewable energy. The heat is often generated through combustion or electrical heating systems. Efficient management of process heat is crucial for reducing energy consumption and minimizing environmental impact in industrial settings.
