[5 Departments: Vigorously promote the clean replacement of coal-fired boilers and coal-fired industrial kilns, and comprehensively eliminate coal-fired boilers of 10 steam tons/hour and below] On November 4, five departments including the National Development and Reform Commission issued the "Action Plan for Implementing a Comprehensive Conservation Strategy." It mentioned that curbing the unreasonable growth of total energy consumption. Strengthen the source control of energy conservation and carbon reduction, strictly implement the energy conservation review and carbon emission evaluation methods of fixed asset investment projects, strengthen the comprehensive review and evaluation of project energy consumption, coal consumption and carbon emissions, implement carbon emission equivalent or reduced replacement for new (renovated, expanded) high energy consumption and high emission industrial projects, and effectively manage and control high energy consumption and high emission projects. New (renovated, expanded) construction coal projects in key areas of national air pollution prevention and control will be replaced by equivalent or reduced amounts of coal in accordance with the law. Vigorously promote the clean replacement of coal-fired boilers and coal-fired industrial kilns, and completely eliminate coal-fired boilers with a capacity of 10 tons/hour or less. Accelerate the heating transformation of coal-fired units and the construction of supporting pipe networks, and eliminate old and inefficient coal-fired units and coal-fired boilers. Promote the elimination of inefficient coal-fired facilities and equipment for agricultural, commercial, and civilian use in an orderly manner.
