Recently, the National Development and Reform Commission and other five departments jointly issued the "Action Plan for Green, Low-Carbon and High-Quality Development of Boilers". The plan aims to promote the green and low-carbon development of the boiler industry, and promote the coordinated promotion of energy conservation, carbon reduction and pollution reduction transformation. In the plan, the key task is to implement energy-saving, carbon-reduction and pollution-reducing transformation. Combined with the "three reforms" of energy-saving and carbon-reduction transformation, heating transformation and flexibility transformation of coal-fired power units, the power station boilers are upgraded and transformed such as matching the main and auxiliary equipment, optimizing the heat exchange system, making the deep utilization of waste heat, and improving the temperature parameters. These retrofit measures will help improve the energy efficiency of the boiler and reduce polluting emissions.
At the same time, on the premise of ensuring safety, we will steadily promote the transformation of boilers for coal-fired power units that have been in service for a long time. This will help extend the life of the boiler, improve operational efficiency, and reduce energy waste and environmental pollution. In addition, we will actively promote the transformation of coupled biomass combustion technologies such as large-scale coal-fired power generation boilers blending agricultural and forestry wastes. This approach will help reduce dependence on traditional fuels, reducing energy consumption and carbon emissions.
In terms of exploring the use of large-scale coal-fired power generation boilers to co-dispose of bulk single-category solid waste, the plan proposes to carry out relevant pilot work under the premise of achieving ultra-low emissions and controllable environmental and safety risks. This will help to improve the utilization rate of waste and reduce the impact on the environment. For industrial boilers, the plan proposes to explore the synergistic transformation and upgrading scheme of energy saving, carbon reduction and pollution reduction according to local conditions, so as to improve the operation control and diagnosis and maintenance level of industrial boilers. This will help improve the operational efficiency and safety of industrial boilers, reduce energy consumption and pollutant emissions. In the case of gas boilers, the plan calls for the active implementation of low-nitrogen retrofits to reduce NOx emissions. At the same time, biomass boilers should be equipped with high-efficiency dust removal facilities, and denitrification facilities should be built if the nitrogen oxide emission concentration is difficult to reach the standard, and other materials such as coal and garbage should be prohibited.
In addition, the plan also proposes that by 2025, the coal-fired boilers retained in key areas and the coal-fired boilers with more than 65 steam tons per hour in other areas will achieve ultra-low emissions. This will help further reduce the environmental impact of coal-fired boilers. In order to continuously improve the standard system, the plan requires accelerating the formulation and revision of relevant standards, including boiler thermal efficiency, system energy efficiency, energy efficiency testing, carbon emission accounting, carbon footprint assessment, energy efficiency evaluation of special boiler systems, supercritical carbon dioxide boilers and other related standards. At the same time, the biomass boiler standard should be formulated and improved, and the combustion control requirements and the initial emission concentration limit of nitrogen oxides should be clarified. In addition, it is necessary to formulate mandatory national standards for the quality of biomass pellet fuel products. The formulation and improvement of these standards will help promote the green and low-carbon development of the boiler industry. Finally, the plan also emphasizes the need to strengthen the convergence and mutual recognition of China's boiler energy efficiency, carbon emission and other standards with relevant international standards.
This will help promote China's boiler industry to be in line with international standards and improve China's competitiveness in the international arena. The introduction of the Action Plan for Green, Low-Carbon and High-Quality Development of Boilers will help promote the green and low-carbon development of the boiler industry and promote the coordinated promotion of energy conservation, carbon reduction and pollution reduction. At the same time, strengthening the formulation of standards and international convergence will help enhance China's competitiveness in the international arena.
