Core Viewpoint - The report highlights significant progress in the management of industrial small coal-fired boilers and building material kilns in the Northwest region, while also identifying ongoing challenges such as insufficient industrial structure optimization and uneven clean energy substitution [5][7]. Industrial Small Boilers - The total capacity of coal-fired small boilers in the Northwest region is approximately 0.8 million steam tons, with coal consumption around 3.53 million tons as of 2024 [5]. - The capacity and coal consumption of coal-fired industrial small boilers nationwide have decreased by 87% and 82% respectively from 2017 to 2024, but the Northwest still accounts for 12.6% of the national coal consumption from small boilers [7]. - Experts suggest a dual approach of "regional differentiated elimination + end-of-pipe deep governance" to address the challenges, emphasizing tailored strategies for different regions [8]. Building Material Kilns - The brick and tile industry has seen a significant reduction in coal consumption, dropping from 236 million tons to 37 million tons, with the proportion of tunnel kilns increasing from 10% to 90% [10]. - The number of brick enterprises in Gansu has decreased from 973 to 218, and in Xinjiang from over 1,000 to around 300, but remaining capacities still face environmental pressures [10]. - A comprehensive governance plan is proposed, focusing on eliminating outdated production capacity, enhancing environmental performance, and utilizing solid waste [11]. Emission Standards and Regulations - The current boiler emission standards are outdated and do not meet the needs of modern pollution reduction and carbon neutrality goals, particularly in the Northwest region [15]. - There is a need to revise local boiler emission standards to include carbon emission intensity, which would provide clearer guidelines for pollution reduction and carbon neutrality efforts [15].
