The "Action Plan for Carbon Peaking Before 2030" (Guo Fa 2021 No. 23) issued clearly points out that it is necessary to "dig deep into potential stock projects, accelerate the elimination of backward production capacity, and tap the potential of energy conservation and emission reduction through transformation and upgrading", and resolutely curb the blind development of "two high" projects. The National Development and Reform Commission and other five departments issued the "Several Opinions on Strict Energy Efficiency Constraints to Promote Energy Conservation and Carbon Reduction in Key Areas" (Development and Reform Industry No. 1464 2021), and issued the "Action Plan for Promoting Energy Conservation and Carbon Reduction in Key Industries of Metallurgy and Building Materials with Strict Energy Efficiency - 2025 Bundle (2021-2)", emphasizing the need to "guide the orderly exit of inefficient production capacity".
In order to fully implement the decision-making and deployment of the industry, various industries are taking a variety of measures in combination with their own development realities to dig deep into the potential of energy conservation, pollution reduction and carbon reduction, and strive to promote the green, low-carbon, safe and high-quality development of the industry. Yes, for a long time in the future, for an industrial project, the ability to regulate production in the face of market changes is the most critical. From the comprehensive analysis of product variety development and comprehensive utilization of raw materials and production control, the mixed lime shaft kiln has incomparable advantages of other kiln types, and only in line with the national industrial policy, to ensure the clean and civilized production of enterprises, to further reduce pollution and carbon, to improve quality and efficiency, the mixed lime shaft kiln can play its own advantages.
First, a high starting point, true science, to ensure that the kiln technology is advanced and reasonable, in line with the national industrial policy.
In the context of promoting green and high-quality development, the lime industry should further promote transformation and upgrading, and continue to optimize the industrial structure. The first is to speed up the elimination of backward production capacity according to the "Industrial Structure Adjustment Guidance Catalogue" (2011) (revised), which is the primary task of the lime industry to achieve high-quality development. The second is to promote the upgrading of existing lime kiln equipment and the construction of new advanced lime kiln equipment, and comprehensively improve the level of process technology, equipment, product quality, energy consumption, environmental protection and other aspects of the lime industry. Advanced and reasonable technology, production standards and production are the basic embodiment of the technological progress of the shaft kiln, in line with the national industrial policy, is the primary condition for the survival and development of enterprises.
2. Strengthen the awareness of environmental protection and establish a new concept of environmental protection.
It is the general trend to formulate a long-term restraint mechanism for the industry based on the level of environmental protection, energy consumption and carbon emissions. Enterprises should take the initiative to speed up the implementation of the carbon peak action plan, the systematic energy-saving diagnosis of the whole plant, and the transformation of environmental protection ultra-low emissions, so as to comprehensively improve the level of energy conservation and environmental protection.
The lime industry should be clearly aware that environmental protection is related to the survival of enterprises, and solving the problem of green environmental protection is a necessary condition for the continued survival and sustainable development of lime enterprises. Lime production enterprises must establish a new concept of environmental protection, adhere to clean production, and take energy saving, consumption reduction and emission reduction as an important measure to adjust the industrial structure and transform the development mode, which is also an inevitable requirement for the sustainable development of enterprises. Therefore, energy-saving improvement and transformation will be a "nirvana" for the lime industry. First, it is necessary to establish the concept of "fully enclosed" environmental protectionSecond, it is necessary to establish the concept of reducing pollution sources;The third is to establish the concept that environmental protection equipment is more important than process equipment, and ensure the normal operation of environmental protection equipment in an all-round wayFourth, the cleaner production of factories must be normalized.
3. Strengthen operation management, improve quality, reduce energy consumption, and improve the viability of enterprises.
From the perspective of industry development prospects, in the context of carbon peak and carbon neutrality, how to further reduce pollution and carbon emissions, improve quality and efficiency in the lime industry has become the focus of attention from all walks of life. Technical emission reduction is becoming the direction of lime enterprises. By improving the process, optimizing the index, improving the energy utilization rate, strengthening the production operation management, optimizing the control of the firing temperature, improving the quality of lime products, and reducing energy consumption, the enterprises can enhance their market competitiveness and improve their viability while optimizing the industrial structure, upgrading the level of kiln equipment, and developing green environmental protection.
Fourth, the mixed lime shaft kiln energy conversion or substitution of comprehensive technical reserves.
From the perspective of the domestic environment, dual control of energy consumption has become a pre-evaluation condition for the development and even survival of the lime industry. In the future, the increase in energy consumption obtained by the lime industry is extremely limited, and reducing energy consumption intensity has become an inevitable choice.
It is necessary to give full play to the product diversity, fuel diversity, output elasticity adjustment and industry application multi-functionality of the mixed lime shaft kiln, and carry out the research and development of special new technologies and technical reserves for the shaft kiln in accordance with the policy and industry development, so as to provide strong technical support for the sustainable development of the mixed lime shaft kiln.
1) Research and promote clean, efficient and low-nitrogen coal-fired gas technology;
2) Research and application of lime shaft kiln technology for solid gas fuel exchange;
3) Carry out special technical research and development for downstream industries, such as large-scale technical research and development of lime shaft kilnsDevelopment of lime shaft kiln process equipment technology in specific deep processing fields;Development of lime shaft kiln technology to expand the range of raw materials.
