"Enterprise Development Seminar Salon Focuses on Coal Power Development under the Goal of "Carbon Peak and Carbon Neutrality

In order to understand the real needs and development bottlenecks of coal power enterprises in Shanxi Province under the background of "carbon peak and carbon neutral", on April 15, Shanxi Kecheng Environmental Protection Industry Co-innovation Research Institute held a seminar on "enterprise development under the goal of carbon peak and carbon neutral". More than 40 people from coal and power companies in the province and industry experts participated in the discussion to discuss the dual-carbon response of coal and power companies.

Qin Yan, Director of Energy and Low Carbon Development Research Office, Research Institute of Science and Environment

First, Qin Yan, Director of Energy and Low Carbon Development Research Office, Research Institute of Science and Environment, made a keynote speech on the "Response of Coal and Power Enterprises to Carbon Peak and Carbon-Neutral Contexts", which focuses on the connotation of the dual-carbon target, the role of the coal and power industry in realizing the dual-carbon target, and analyzes the opportunities and challenges faced by the coal and power industry in the comprehensive development. She comprehensively analyzed the opportunities and challenges faced by the coal power industry, and gave solutions and suggestions on strategic decision-making, statistical accounting, cost management and basic capacity reserves.

She pointed out that the coal power industry is a key area for the realization of the national and Shanxi peak carbon goals and carbon neutral vision, and that coal power enterprises, as the main implementation body of carbon reduction, should attach great importance to it, respond to it seriously, incorporate the concepts of peak carbon and carbon neutrality into the development strategy and planning of the enterprise, coordinate the relationship between their own operation and development and the reduction of carbon emissions, and avoid making decisions that deviate from the direction of carbon reduction / carbon neutrality; emphasized that enterprises need to comprehensively and systematically map out the current status of their carbon emissions, and to make a comprehensive and systematic assessment of their own carbon emissions. It also emphasizes the need for enterprises to comprehensively and systematically map out their own carbon emission status quo, make a good assessment of their carbon emission reduction potential and multi-benefits, and give medium- and long-term corporate emission reduction targets, paths, strategies and implementation steps; and at the same time, do a good job of reserving capacity in terms of personnel staffing, carbon emission data system construction, and carbon emission management system construction.

Wei Li, Director of Solid Waste Technology and Industry Research Center, Techcity Environmental Research Institute (first from left)

Subsequently, Wei Li, Director of Solid Waste Technology and Industry Research Center, Techcity Environmental Research Institute, delivered a speech on "Exploring Solid Waste in the Thermal Power Industry". She analyzed the characteristics of coal pulverizer fly ash, circulating fluidized bed fly ash, desulfurization gypsum generation and comprehensive utilization in the thermal power industry.

She proposed that the study of solid waste generation law is a substantive work to solve the solid waste consumption mode, and suggested that the study of solid waste generation law in the thermal power industry should be a systematic thinking from the raw and auxiliary materials involved in the solid waste generation process, production conditions, flue gas ultra-low emission process, desulfurization wastewater treatment process, denitrification process, as well as the solid waste pretreatment measures, etc., and study the links of the substances into the solid waste, the form and its migration and transformation laws, and analyze the impact of various substances on process parameters and pollutant emissions in the downstream comprehensive utilization process. On this basis, it is proposed that if the amount of solid waste generated is reduced at source and the composition of solid waste is optimized, it may be possible to promote its comprehensive utilization with less input, e.g., the chlorine content in the desulfurization gypsum of some thermal power plants fluctuates greatly, and it is necessary to improve the recycling cycle of the desulfurization wastewater and its treatment, so as to make the chlorine ions in the desulfurization gypsum less enriched, which will be conducive to the promotion of desulfurization gypsum used in the field of building materials. Therefore, the key link to solve the high chlorine content of FGD gypsum is to treat the FGD wastewater discharged from the flue gas desulfurization system of the limestone-gypsum method in a timely manner to meet the standard, and to guarantee the dehydration efficiency of FGD gypsum and reduce its water content, so as to improve the quality of FGD gypsum, which can make the calcium sulfate dihydrate in FGD gypsum reach more than 85%, and the chlorine ions control is less than 600ppm. According to the different quality levels of desulfurization gypsum ("Flue gas desulfurization gypsum" GB/T37785-2019), it can be used as a cement retarder or to produce plastering gypsum, gypsum blocks, paper-faced gypsum, and a-high-strength gypsum powder, etc., respectively.

Finally, Wei Li briefly analyzed the challenges and opportunities faced by thermal power enterprises in co-disposal of solid waste, introduced the use of pulverized coal furnace, circulating fluidized bed boiler power generation enterprises in co-disposal of municipal sludge, straw and other biomass fuels and other actual cases, suggesting that enterprises from the co-disposal of solid waste to increase new industrial opportunities, synergistic carbon reduction, to assume more social responsibility, to form a multi-win situation.

Zhang Peihua, President of Shanxi Environment and Comprehensive Utilization of Resources Association

Zhang Peihua, President of Shanxi Environment and Comprehensive Utilization of Resources Association, emphasized that the current thermal power unit loads are not high, the intermittent peaking role of coal power is irreplaceable, and in the face of the dual-carbon goal, coal power enterprises need to rethink their positioning and way out. Suggest gangue power generation enterprises in the solid waste resource utilization and energy efficient use of a good balance between accounting for carbon emission reduction and solid waste resource utilization of economic accounts. Finally, it is suggested that the marketization of desulfurization gypsum has a broad prospect, and it is called on the coal power enterprises to optimize the management of flue gas desulfurization, reduce the water content and chlorine content of desulfurization gypsum, improve the content of active ingredients, and promote the comprehensive utilization of desulfurization gypsum.

Ma Guorong, Secretary General of Shanxi Environmental Protection Industry Association

Ma Guorong, Secretary General of Shanxi Environmental Protection Industry Association, pointed out that carbon verification is the main task faced by coal and power enterprises, and introduced the green ironmaking strategy of replacing coke with hydrogen in the iron and steel industry and its examples, suggesting that coal and power enterprises map out the bottom line of carbon emissions, understand their own carbon footprints, and deploy carbon emission reduction in advance to cope with the situation.

Gao Daoping, first-level researcher of Shanxi Energy Bureau

Gao Daoping, first-level researcher of Shanxi Energy Bureau, pointed out that the reduction of coal and control of electricity in the context of dual-carbon has become the province's most urgent problem, and the situation of energy saving and efficiency improvement at the enterprise level is grim; the total amount of energy consumption and the intensity of the "dual-control" is a systematic project, which needs to be sustained from technological progress, structural optimization, management reform, and other aspects, The "double control" of total energy consumption and intensity is a systematic project, which requires continuous efforts from technological progress, structural optimization, management reform and other aspects.

Wei Shaoqing, Deputy General Manager of JINNERGY POWER GROUP

Wei Shaoqing of JINNERGY POWER GROUP said that the pressure on the survival of traditional coal-fired power is great, and the responsibility of supplying heat, gas, water and cold is heavy, and it is extremely important to change the concept of the decision-making level of the enterprise to find out the carbon emissions of coal-fired power enterprises and to respond positively to the challenges of carbon emission reduction work. He pointed out that JINNERG is currently establishing CFB ash in the road construction and filling standards, hoping to promote the development of thermal power industry bulk solid waste utilization process.

Zhang Qingjiang, Director of Technology Center of Shanxi Road and Bridge Construction Group Co.

Zhang Qingjiang of Shanxi Road and Bridge Group introduced the current situation of Shanxi Road and Bridge Group's comprehensive utilization of bulk solid waste and expressed the hope that the government will introduce a subsidy policy for the utilization of bulk solid waste to encourage enterprises to carry out research on the comprehensive utilization of bulk solid waste and optimize their transformation to cope with the opportunities and challenges brought by the "double carbon". "

The conference was held in Beijing, China, from November 10 to 15, 2011, and was attended by more than 100 participants.

Representatives of the participating enterprises also discussed and exchanged views with experts on key issues such as the object of carbon trading, the main body, the process, the method of accounting and determining quotas and how to monitor.

The salon seeks to strengthen the enterprises' understanding of the dual-carbon target and inspire them to reduce carbon emissions and comprehensive utilization of solid waste at the operational level. Under the new development situation, Kecheng Environmental Research Institute will continue to carry out professional research and actively build a platform for exchange and cooperation among the government, enterprises and experts in the field of energy and environmental protection, so as to provide high-quality services and scientific advice to enterprises and the government in the process of implementing the carbon neutral process of peak carbon emission reduction in Shanxi.
