Zhejiang Lishui Power Supply: Electricity Substitution Promotes Clean Energy Consumption

"The products fired in a gas kiln have three colors in one kiln. After changing to an electric kiln, the products fired at the upper, middle and lower layers are exactly the same, and the pass rate of the finished products has increased by 8-9%. Each point increase in the qualification rate will reduce the production cost by one point. The "distance" in the middle is our net profit." On November 4, in the kiln workshop of Longquan Jinhong Porcelain Co., Ltd. in Lishui City, Zhejiang Province, two Midogao’s electric kiln is firing celadon bowls at full power. The upper three-phase watt-hour meter and the temperature control of the upper, middle and lower floors of the electric kiln are all displayed in real time. Ye Jianren, the deputy general manager of the company, was checking the production situation in the workshop and talking about the benefits brought by electric energy substitution.

After thousands of years, the celadon industry is still the characteristic pillar industry of Lishui Longquan today. As the world's only ceramic project selected as "Intangible Heritage of Mankind", "fire" plays an extremely important role in the firing process of Longquan celadon, and electric energy as a clean energy source is driving profound changes in the celadon industry.

In order to deeply implement the concept of "Two Mountains", Zhejiang Lishui Power Supply Company took the opportunity to promote the creation of a "National Clean Energy Demonstration Province", took electric energy substitution as an important starting point, and actively cooperated with the government to promote the implementation of a number of significant economic and social benefits. Electricity replacement project. Among them, the Lishui Company combined with the theme education of "Don't forget the original heart, keep the mission in mind", oriented to serve the needs of enterprises, and combined with the actual energy use characteristics of local celadon manufacturing enterprises in Longquan City, to carry out innovative exploration and practice of electric energy substitution mode, and proposed replacing gas with electricity. Technology, developed a celadon electric kiln and demonstrated application in the celadon firing process. At present, under the demonstration and guidance of Jinhong Porcelain Industry, a leading enterprise in the celadon industry, a total of 176 celadon enterprises have completed energy-saving renovations of electric kilns. The use of electric furnaces also brings significant environmental benefits. The carbon emissions of using electric kilns in the production process of daily-use porcelain can be reduced by 24.26 kg/m3·year compared with gas kilns, and the carbon emissions generated during the stage of working with electric kilns in the production process of craft porcelain are reduced by 10.11 compared with gas kilns. Kg/m3·year.

In recent years, Lishui Company has vigorously promoted electric energy substitution projects. In the traditional electric energy substitution field, the company has continued to carry out electric kilns, electric tea, mushroom heat pump processing, etc.; in the emerging electric energy substitution field, vigorously promote all-electric kitchens and all-electric scenic spots , Electric vehicles, port shore power, etc. Up to now, Lishui City has completed more than 400 electric energy substitution projects such as substituting electricity for oil and electricity for coal, which has driven approximately 283,600 tons of standard coal energy savings and reduced carbon dioxide emissions by nearly 700,000 tons.

At the same time, Lishui Company took the initiative to coordinate with the local government, and successively issued the "Implementation Opinions on Accelerating the Promotion of the City's Electricity Substitution Work", "Implementation Opinions on Further Accelerating the Development of the Service Industry", as well as policies such as financial subsidies for electric energy substitution projects in the industrial field, and promoted Lishui City Governments at all levels have increased their support for various types of electric energy replacement and transformation.
In the next stage, Lishui Company will continue to broaden the channels for electric energy substitution, deepen electric energy substitution measures, continue to accelerate the construction of electric energy substitution projects, and promote local clean energy consumption.
