It is understood that the Jiminxin Gaoan clean energy project has a total investment of 6.5 billion, and after full operation, it can produce 12 billion m³ of clean industrial gas annually. It is estimated that it can save 263,000 tons of standard coal for Gao'an ceramic construction base enterprises every year, reduce emissions of more than 57,000 tons of sulfur dioxide and more than 16,000 tons of nitrogen oxides, and greatly solve environmental pollution problems such as phenol water and tar. The centralized gas supply of this project in the ceramic construction base is the first of its kind in China, and it is a precedent regardless of its technology, technology, and process.
The Gao'an Jimin Trust Centralized Gas Supply Project replaces the company's self-made gas with the clean gas supplied centrally, and centrally pre-treats scattered pollution sources, greatly improving the clean production capacity of high-energy-consuming industrial clusters. Centralized gas supply mainly consumes solid fuel coal, supplies clean gas, and realizes environmentally friendly centralized pre-processing. In China, a large energy-consuming country with rich coal and poor gas, it has played a major industry leading and demonstration role. The replicability of the project also makes it one of the important models to solve China's energy shortage.
As the largest centralized coal-to-gas project in China, on December 13, 2020, under the attention of the whole industry, the Jimin Credible (Gaoan) centralized gas supply project officially entered the trial operation stage, and will be divided into two phases to Gaoan. 40 ceramic companies in the ceramic construction base have been supplied with gas for more than 130 days, and the total supplyThe gas volume is approximately 690 million m³, and the expected trial production goals of safety, stability, cleanliness, energy saving and consumption reduction have been achieved overall.
It is understood that during the 130-day trial operation of the centralized gas supply project, it was further verified that the process flow of the Jimin Credible (Gaoan) centralized gas supply project is feasible and the project operation is safe and stable. At the same time, in response to issues such as gas supply pressure, calorific value and product quality that gas users were concerned about during the trial operation last year, with the joint efforts of the Jiangxi Ceramics Industry Base Management Committee, the technical team of Jingdezhen Ceramics University and gas users, we The goals of stable air pressure, calorific value and product quality have been basically achieved. A considerable number of enterprises use centralized gas supply, and the gas consumption is equal to or lower than self-made water gas.
Problem can be solved:
Air pressure, energy consumption, and product quality issues are basically solved
According to "Ceramic Information", the Gao'an centralized gas supply project is undergoing a 75-day phased planned shutdown for maintenance. It is not a problem with the system and structure of the project itself, but a comprehensive inspection and elimination of defects in the project's production equipment. , provide guarantee for the follow-up long-term, safe, clean and stable gas supply, improve the safe and stable operation capability of centralized gas supply, and completely solve the clean production problems of ceramic enterprises in Gao'an Ceramics Base.
According to Chen Weimo, assistant to the chairman of Jimin Credible (Gaoan) Clean Energy Co., Ltd., the construction of the Jimin Credible centralized gas supply project has been fully completed and settled, and the project has met the conditions for comprehensive gas supply. The purpose of shutting down production for maintenance is to summarize the experience gained during the trial ventilation period, optimize and improve the project again, and lay a solid foundation for comprehensive gas supply.
Since the trial operation of the Jimin Credit Centralized Gas Supply Project on December 13 last year, many business leaders in the Gaoan Ceramics Production Area said that the gas provided by the centralized gas supply project is cleaner than self-made water gas, which solves the problem for enterprises There are no worries about environmentally friendly production, but there are also problems such as air pressure fluctuations, increased energy consumption, and fluctuations in product quality.
The Gao'an Municipal Party Committee and Government attach great importance to this, and have entrusted the Ceramics Base Management Committee to invite experts and the China Testing Technology Research Institute to conduct on-site sampling, test and analyze the composition and calorific value of Jimin's trusted gas source, and demonstrate Jimin trusted the problems and feedback encountered by various ceramic companies during the trial operation of "centralized gas supply" and held multiple technical seminars to find optimal solutions.
In order to promote the safe and stable operation of centralized gas supply projects and truly achieve the goals of energy saving and consumption reduction, centralized gas supply not only realizes clean production in Gao'an production areas, but also serves as a step towards high-quality and sustainable development of Gao'an ceramics industry. important promoter.
In February 2021, Jiangxi Architectural Ceramics Industry Base Management Committee specially hiredA technical team of more than 20 people involved in thermal engineering, materials, automation and other professional fields, led by Feng Qing, a professor at Jingdezhen Ceramics University, was invited to conduct technical diagnosis on the production line of the original gas testing enterprise and conduct technical inspections on Jimin Credible's "centralized gas supply" process. Follow up and provide guidance, and conduct technical research based on the characteristics of clean gas fuel and the use status of existing ceramic enterprise kilns to solve various technical problems in the use of clean gas.
According to Professor Feng Qing, through nearly four months of technical research at the Gao'an Ceramics Construction Base, the technical team has confirmed that "Jimin's trustworthy clean gas is available, ceramic companies can produce normally, and gas is available for the "centralized gas supply" project. The five phased goals of "consumption is close to self-made water gas, gas consumption is equal to self-made gas, and gas consumption is less than self-made gas" have all been scientifically judged to be "completely achievable". Problems encountered by enterprises during use can also be solved by improving corporate management levels. solve.
It is understood that Professor Feng Qing’s team conducted a 4-month investigation into the operation and gas consumption of the kilns of the gas-using enterprises in the ceramic base, as well as the common problems that emerged after centralized gas supply. The company has improved and provided technical guidance on furnace equipment and kiln operation technology, which has reduced the energy consumption of the centralized gas supply project by more than 20% compared with the same period last year during the initial stage of trial production.
Chen Weimo emphasized that after more than four months of trial ventilation, the problems reported by gas-consuming companies such as pressure fluctuations and high energy consumption have been basically solved so far. Through technological upgrading, as well as the improvement of ceramic companies’ kilns and operating skills, After comprehensive ventilation, the comprehensive cost of Jimin Credible will also be reduced. At that time, the unit energy consumption of the enterprise will even be lower than that of self-made water and gas.
At the same time, Jimin Credibility will continue to make efforts in extended services in the future, assisting ceramic manufacturers to save energy, reduce consumption, and improve quality by optimizing voltage regulation systems, improving operating skills, implementing safe production, and upgrading energy-saving solutions.
What to expect in the future:
