Cement Industry
The cement industry has been a pioneer in adopting WHRS in India. Companies like Ultratech Cement and ACC Limited have implemented waste heat recovery power plants (WHRPP) across their manufacturing units. Ultratech Cement, for example, has installed WHRPPs with a cumulative capacity of over 100 MW, significantly reducing their reliance on grid electricity.
Steel Industry
The steel industry, another major energy consumer, has also embraced WHRS. Tata Steel’s Jamshedpur plant is a notable example, where waste heat recovery systems have been integrated into their blast furnaces and coke ovens, leading to energy savings and reduced greenhouse gas emissions.
Petrochemical Industry
In the petrochemical sector, Reliance Industries Limited (RIL) has implemented advanced WHRS at its Jamnagar refinery. This system captures waste heat from flue gases and utilizes it to generate steam, which is then used for various industrial processes, enhancing overall energy efficiency.
Oil Industry
In refineries, waste heat recovery is typically implemented in process heaters, boilers, and flue gas streams. Technologies such as heat exchangers, recuperators, and waste heat boilers are commonly used. These systems capture high-temperature heat from processes like crude oil distillation and catalytic cracking, reusing it to generate steam or electricity.
Indian Oil Corporation Limited (IOCL), one of India’s largest state-owned oil companies, has implemented waste heat recovery systems across its refineries. These systems have significantly improved energy efficiency, reducing both operational costs and greenhouse gas emissions.
Food Processing
Companies in the food processing sector use waste heat recovery for refrigeration and heating applications, optimizing energy use in their operations.
Textiles
Textile manufacturers utilize waste heat recovery systems to capture heat from boilers and dryers, improving overall energy efficiency .
Energy Savings
According to the Bureau of Energy Efficiency, implementing waste heat recovery systems can lead to energy savings of 20-30% in industries.
Market Growth
The Indian waste heat recovery market is projected to grow at a CAGR of 8.6% from 2021 to 2026, driven by increasing industrial activities and favorable government policies.
Carbon Reduction
Industries adopting waste heat recovery have reported a reduction in CO2 emissions by 10-15%, contributing to India’s climate goals.
