响应国家“双碳”战略 水泥企业大力推广余热发电

Group 1 - The cement industry is actively responding to China's "dual carbon" strategy by implementing ultra-low emissions and energy-saving carbon reduction modifications, utilizing distributed photovoltaic power generation and waste heat power generation technologies as effective means for energy conservation and emission reduction [1] - Waste heat power generation technology recovers medium and low-temperature waste heat from the kiln head and tail emissions to generate electricity, converting thermal energy produced during clinker production into electrical energy, thus achieving resource recycling, saving traditional electricity, and reducing carbon emissions [1] - In 2024, Ta Pai Group reported a waste heat power generation output of 34,374 million kWh, reducing carbon emissions by approximately 330,000 tons [1] - Shangfeng Cement utilized waste heat power generation to produce 473 million kWh in 2024, resulting in a reduction of carbon emissions by 389,800 tons [1] - Yatai Group implemented pure low-temperature waste heat power generation measures in 2024, reducing carbon emissions by 115,600 tons [1] - Wanyanqing has ten operational waste heat power generation units with a total installed capacity of 80.30 MW, which can meet about 50% of the electricity demand for the company's kiln system [1] - In August 2023, a waste heat power generation project by Xinjiang Tianshan Cement Co., Ltd. had an installed capacity of 10 MW, generating an annual output of 44.08 million kWh and reducing carbon emissions by 3,700 tons annually [1] Group 2 - According to analyst Li Kunming from the China Cement Network, waste heat power generation has become an important plus for downstream concrete and construction companies in terms of "green procurement" and ESG ratings [2] - Waste heat power generation can enhance the image of cement companies, increase social responsibility, and help them secure more green orders and enter green supply chain white lists [2]
