Since May 2016, "the guidance on the promotion of electric energy substitution" issued, the local power companies have taken the initiative to promote the substitution of electrical energy and civilian coal combustion, has achieved remarkable results. Reporter recently in Hunan Chenzhou survey, learned that state-network Hunan Power company adopts contract energy management mode to promote the Hongzhou coal-fired large-cap foundry industry to implement "Coal to change electricity", which greatly reduces the pollution emission from the combustion of dispersed coal, which also plays a significant exemplary role in promoting the power substitution in the industrial field of Hunan province.
Electric energy revolution of "Jiangnan foundry"
In the industrial park of Jiahe County, Chenzhou, Hunan, the electric kiln equipment, known as the "intermediate frequency Furnace", is becoming a new hot topic in the foundry industry in the park.
Prior to this, the enterprises in the region used coal burning furnace as a melting equipment, the more than 10-metre-high coking coal as the main fuel of the equipment is vividly known as "cupola." "Before using cupola, burning the taste of coal is heavier, chimney to smoke, give people feel really not very good, pollution or more severe", Jiahe Red de Mechanical and electrical casting company General Manager Assistant Shu Ningyong told reporters.
Red German mechanical and electrical casting is jiahe a typical family foundry, Shu Ningyong has been the third generation of its family foundry industry. "grew up in the factory, before here are smoke, smoke diffuse." Last year we changed the medium-frequency stove, the whole plant has been completely different, you can see, almost no pungent taste, operation is also greatly simplified, as simple as the touch-screen mobile phone, in leading reporters to visit the factory, Shu Ningyong to the factory on the new set of electric furnace equipment praise.
Red Tak Electrical and mechanical located in the temple Industrial Park, is Jiahe County to undertake the Guangdong coastal industry transfer of the main platform, gathered near hundreds of casting, forging manufacturing enterprises, Jiahe County also known as "Jiangnan cast."
The May 2016 issue of the "guidance on the promotion of electric energy substitution" explicitly mentioned that in the metal processing, casting, ceramics, rock wool, microcrystalline glass and other industries, in conditional areas to promote electric kiln. In September 2015, the Hunan energy-saving company has already signed an agreement with the first 10 enterprises of the temple Industrial Park to help the park enterprises to install electric kilns and replace cupola.
Also located in the temple of the industrial park in the Jiahe Casting Co., Ltd. is also jiahe "Coal to change electricity" the first beneficiaries. Chairman Huangneting is the president of Jiahe County Foundry Association, he gave reporters a sum of accounts: In the past when the use of cupola, the cost of the production of coal per ton of castings around 300-400 yuan, the use of electric kiln, if the night trough price calculation, the cost of electricity to 4 cents per ton of castings only this piece of cost can save more than 100 yuan. Equipment automation significantly improved, the kiln sector of the employment has been reduced by more than half, the human cost significantly reduced. More importantly, the medium-frequency furnace production because there is no coal dust impurity problem, quality significantly improved, product prices also have a 20%-30% increase, now exported to Southeast Asia.
Chen, project manager of Hunan Energy-saving service company, told reporters that the coal conversion project of Chenzhou Foundry industry not only can realize the environmental benefit brought by electric energy substitution, but also bring the economic benefit to the enterprise, which is the key to the smooth promotion of the project.
Contract energy management for electric energy alternative paving
China network Hunan Energy-saving service company General Manager Lo Zhikun will Jiahe "coal to electricity" the smooth progress of the first credit to the successful implementation of the contract energy management model. "To change the traditional cupola furnace for the medium-frequency furnace, the first equipment itself costs need millions of, but also need to support the construction of transformers and other infrastructure, early investment, for their own capital and technical lack of foundry enterprises to accept very difficult." Therefore, our national network company decided to provide funds and technology, the use of contract energy management. "he said.
Contract Energy Management (EMC) refers to energy-saving service companies and users to enter into a power management contract, the energy-saving services company to undertake the relevant equipment transformation cost input, and energy-saving benefits sharing and other ways to achieve investment recovery and reasonable profits. Concrete to the foundry industry "coal to change electricity", is by the state network Hunan Energy-saving service company to invest in equipment upgrading enterprises, enterprises through the equipment to obtain this part of the proceeds of return to energy-saving company investment. According to Lo Zhikun Introduction, at present, because Jiahe "coal to change Electricity" project for the Enterprise efficiency effect is obvious, basically investment can be recovered within one years.
"We have a power company like this before the impression is to collect electricity, I did not expect they will come to us to talk about business, willing to invest to help us transform the equipment, but also provide a full range of services," a golden Harvest foundry business manager told reporters.
In order to tie in with the foundry industry "coal to change electricity", the state network Chenzhou power supply company invested nearly 100 million yuan to create a new 220,000 kv substation and supporting 10,000 kv High-voltage road, directly to the industrial park.
