Tengxian Industrial Park is a ceramic enterprise person in charge when talking about this year especially serious shortage problem, very anxious:" since the government began, productivity is greatly affected, generally lack of capacity 50%." Not only that, in September 8, there are some ignition production line, as a result of power can not be put into production on schedule, and part of the enterprise in the original plan this Foshan Tao Bo will release new products, but also because of power cause, will have to postpone the release of new products; on the other hand, because the normal production of the enterprise can not be guaranteed, in order to control costs, most ceramic enterprises to return the original jobs over the technical staff and production workers, or spend money raised part of the core technical staff, cause severe pecuniary loss to the enterprise.

The situation of shortage of East China Southern China region is particularly serious ceramic information, as in a city
Guangxi has nearly 20 years of the most serious a drought events, not only to the large number of ceramic enterprises caused inestimable loss to the life of local residents, but also brings great inconvenience, one time attracted wide attention from all sectors of society. In fact, as early as in April this year, affected by the water power declined and the influence of factors such as thermal power coal prices high, Jiangxi, Hunan, Guizhou, Chongqing and other places of electricity is very nervous, from the eastern to the Western multi province sustained load gap, wherein the power separation amounts to 2710000 kilowatt, Zhejiang, Jiangxi, Chongqing, Hunan, Shaanxi respectively reached 1400000, 1210000, 1140000 and 950000 kilowatt, appeared large area flood, Bifeng electricity and power etc..
Compared with previous years, this year shortage time ahead of many, this also makes the local power supply department and the enterprises lack of adequate preparedness, when the limited TV area spread, many enterprises to get orders, but they can not work, the enterprise also seem to feel helpless. In Hunan, Yueyang, from the beginning of 5 large area power brownouts since, new wall building materials Industrial Park in the enterprise has been in half stop state, even local residents of electricity are restricted to four hours every day; in Jiangxi, Gao'an has welcomed is referred to as "the history of the most severe drought", according to Jiangxi province electric power company introduce the persons concerned, Jiangxi power supply situation of tension, usually occurs in summer or winter peak period, but this year for the first time" off-season" phenomenon of lacking electricity, peak power gap even reached 1300000 kilowatts.
In addition to Jiangxi, Hunan to encounter outside Guangdong, shortage, in southeast coastal economy developed area also suffered varying degrees of electricity shortage. In Qingyuan, Zhaoqing, to, Foshan,, ceramic enterprises have suffered staggering power consumption in power, these regions of the enterprises, has become the norm, most enterprise itself is equipped with the power equipment, to ensure that production needs.
"The moon is curved according to Kyushu, a few joy a few anxious." In the East, Southern China and other ceramic-producing areas with electricity, seriously affect the normal production of the enterprise at the same time, Jinjiang, Jiajiang, Zibo, Hebi and other ceramic-producing areas has not got electricity effect, enterprises normal production. Taking Jiajiang as an example, Jiajiang ceramic industry power consumption accounted for 90% of electricity consumption of Jiajiang county industry, as the pillar industry of Jiajiang, the government of Jiajiang will give priority to meet the demand for electricity in ceramic enterprises. In Fujian, Jinjiang, in recent years there are no shortage phenomenon, it is with Jinjiang city hall high attention about power construction. Jinjiang city manufacturing industry developed, electricity consumption increased by 13% per year, the electricity sector to make reasonable power planning, to ensure that the electricity supply and electricity synchronous growth, enterprise meet the demand for electricity.
Enter autumn since, countrywide each district electric shortage situation eased. According to the National Energy Bureau in September 15th statistical data shows, August national power consumption of the whole society grows 9.1% compared to the same period, from June 13% and July 11.8% growth slowed down further.
The major areas in the near section time will gradually get rid of the shortage problem, have normal production. However, the next period of time, the power situation is still not optimistic, especially in Southern China and East China coastal industry more developed regions, industrial electricity tensions still will be very difficult to avoid.
Multiple factors generating electricity this winter and next summer or more power
In recent years, our country electric power supply form of more and more serious, this is particularly serious, appear much electricity in advance," off-season" power shortage phenomenon is very common, the power gap generally larger, so that the peak electricity consumption, power and other frequently occur, a serious impact on China's economic development and living order. City Network
The country will appear so big area drought phenomenon, industry experts have pointed out that, because of power shortage of investment, economic development caused by excessive electricity shortage, coal prices remain high, water shortage hydropower supply drops and other factors, however, the most important is after the financial crisis intensified inflation eventually spread to the power of this relationship to the beneficial to the people's livelihood last bottom line price.
With the continuous economic development, electric power demand and increasing power generation amount, difficult to meet the demand. Taking Jiangxi as an example, this year 1 to in April, Jiangxi's total electricity consumption of 26129000000 kwh, an increase of 23.08%, ranking third in the country during the same period growth; grid called EC amounted to 23415000000 kwh, an increase of 32.48%. Power demand is unconventional, unexpected growth posture, in power increase circumstances, grid is facing a shortage of coal and water, thermal power unit available capacity shortage problems, power supply tight situation continuously.
Secondly, for many years, our country coal price already market, while the price of electricity is the administration of. Along with the coal price goes high all the way, electricity prices are running in place, resulting in a lot of thermal power enterprises into a" production more, loss is more" odd group, the unbearable cost goes high all the way, starting with " equipment" wait for a variety of reasons and excuses stopping production. Shanxi province 's electricity shortage this summer is the best example, as our country produce coal big province, this summer because of thermal power unit" unplanned outage" and blocked output while the influence of the generating capacity of more than 14000000 kilowatts, causing the Shanxi gap exceeds 2000000 kilowatt power.
In addition, since late April, the temperature rises apparently, the weather is dry, rainfall, river water to reduce the amount of water power, a serious shortage of. In under the influence of many factors, many in the industry and experts predict, our country is short of electric situation or will exist for a long time. The national grid is forecasted recently, the largest winter electricity load will grow 10% compared to the same period. In the coal supply tight situation falls, our country still will have bigger power gap, wherein, North China, East China, central China and the Beijing-Tianjin-Tangshan, Shandong, Jiangsu, Zhejiang, Hubei, Henan, Hunan, Jiangxi and Chongqing provincial electric power supply and demand will still nervous.
China Southern Power Grid is expected this winter, the 5 southern provinces and regions in 1400 Wanqianwan power gap around the first half of next year, the power gap will reach 10000000 to 15000000 kw.
A number of measures to address the shortage of macro-control to ease the pressure
Face in last few years the most serious one" electric shortage", enterprise of type of production preparation of limited power in suffering, especially in ceramic industry, due to the nature of its production particularity, ceramics production requirements of continuity and stability, so most of the ceramic enterprises are from the year open kiln ignition, has been the production to the end of the year, be restricted to ceramic enterprises, losses will be very big.
For most businesses, shortage of fact can not be changed, but not in the short term to adequately address, how to deal with the shortage of electricity, ceramics enterprises must face the realistic problems. After all, for electricity effect only partial area, still have quite one part area was not affected by the impact, in part by limiting impact areas, is bound to be a fall in production, and reduce the sale radius, weaken the competition ability of the product.
Although some enterprises can buy Generators, but high cost, but also allow enterprises to bear. October 15th, CCTV economy channel" China financial news" reported this year in ceramic industry suffered a drought, a Foshan ceramics enterprises responsible person said, before every degree of electricity price is 0.65 yuan, diesel power generation cost of each is 1.3 yuan, from April 21st until July 14th, just two months time enterprise, consume 368600 degree of electricity, diesel consumption reached 83.57 degrees, in fact the extra spending 470000 yuan.
In the field of power" to defend the war", the enterprise wants to have the ability to solve the electricity problem, it is difficult to add, the most important thing is to rely on the country's macro-control policy to alleviate the shortage of the loss of pressure. According to the ITU data shows, this year first quarter, chemical industry, building materials, steel smelting, non-ferrous metal smelting four key sectors of electricity amounts to 351200000000 kilowatt hour, total electricity consumption in the proportion of 32.2%. From this point of view, with high energy consumption industry led power demand growth is vigorous, is one of the important reasons of the shortage of power. Therefore, the NDRC issued earlier in the" orderly power use management approach" clear, principle, key limit violation completed or under construction project; the adjustment of industrial structure directory eliminate, limiting class enterprises; energy consumption of unit product is higher than the national or local compulsory performance consumption quota of enterprise; landscape lighting, lighting engineering and other the high energy consumption, high emission enterprises and other five kinds of electricity enterprises.
Thus, power units will be in shortage of power supply, emergency situations, by administrative measures, economic means, technical method, to control part of electricity demand, reach the limit of high energy consumption industrial purposes, in order to maintain the order of electric power supply and stable management work. At the same time, the country is strengthening the surplus power to power shortage regions transmission work area. Such as Fujian, as of May this year, so far, already accumulative total to East China power grid transmission capacity 2345000000 kwh, compared with the same period last year growth of 66.96% over the last year, conveying a half of the total, to mitigate the power shortage situation in East china.
At the same time, starting from May this year, partial area industrial electricity prices have risen about two cents per degree, but civilian price unchanged. Recently, the State Electricity Regulatory Commission spokesman Tan Rongyao said, the situation of electricity this winter and next spring tension, maximum power gap of about 26000000 kilowatts, of which is short of coal and water to the South and central China electricity situation is most serious. In view of the current difficulties, Tan Rongyao thinks, the key is to promote the price reform, play electrovalency leverage role in some provinces, upregulation of coal-fired power plants in electricity price, perfect power peak-valley time-of-use electricity price.
To promote the adjustment of industrial structure upgrading of equipment energy saving
For the power consumption of ceramic enterprises, this year's electricity for the development of enterprises is fatal. According to Foshan ceramic enterprises responsible person revealed, in the summer of rationing period, formerly the 250A high voltage power supply into 60 - 80A, the voltage is only enough for furnace insulation. Therefore, the ball mill workshop, polishing machines and other high energy-consuming equipment stopped, but the press, kilns and other equipment can't stop, stop once the furnace will have a great loss. Reportedly, the shortage of the most serious period, had to pull brake to be restricted report incidents, many enterprises of kiln products are scrapped, direct damage to the highest hundred thousands of yuan.
In the face of limit pressure and ceramic production line electricity demand contradiction, enterprises through strengthening the energy-saving measures to reduce electricity consumption, the very period is very important. Tang Yonghua said, in power period, ou Shennuo rely mainly on improving efficiency to achieve the aim of reducing energy consumption. In the jurisdiction of polishing workshop, he mainly used absorbent stick instead of fan to achieve energy-saving effect. He explained, an average of one fan power consumption is the 5.5kW, a kiln needs four fan, so if the fan, a kiln power consumption will increase the 22KW, and the water absorbing rod is not electricity, this can save a lot of energy. In addition, the kiln waste heat supply drying kiln for reuse, but also an energy-saving measures.
The expert thinks, with" electric shortage" continue to increase, the future of the country is likely to increase the price of electrified wire netting to improve high energy consumption industry production cost, so, for those with high power consumption and low added value of polishing brick products, will face greater challenges, and the energy consumption is relatively high, additional cost high antique brick, stone ceramic products, will have a competitive advantage, promote the optimization and upgrading of product structure of ceramic enterprises to develop in the direction of.
The shortage of the environment, relying solely on the ceramic enterprises to achieve energy saving effect, is clearly not enough. As the ceramic industry in the upstream industry, ceramic machinery industry for the ceramic industry provides technical innovation, improve product quality, energy saving and environmental protection has made important contribution, ceramic machinery enterprises by mechanical equipment upgrades to reduce power consumption, now is not the inevitable choice of temporary power phase section.
In the energy saving for increasing case, kiln company developed the super energy-saving wide section tunnel kiln, roller kiln structure based on continuous improvement, increase the kiln body width, so that the unit length yield can be improved, while the vault structure, so that the air in the kiln to reduce resistance. Super energy-saving wide section tunnel kiln successfully, and ordinary kiln, comprehensive reduce power consumption by 15% - 20%.
Not only that, in the energy-saving measures, the company also took the lead in kiln by all fans using inverter control technology, the motor voltage and current can be adjusted according to different load, so that the line loss and motor copper loss to a minimum. Through theoretical calculation and engineering comparison of measured data, the application of this technology makes the furnace to reduce power consumption by 20% or so, especially the part of wind machine used precision control technology, power consumption is further reduced.
According to Zhang Tonglin, in order to further reduce the line loss, kiln in the company through the improvement of fan control device, such as increased air conditioner, the equipment is mounted proximate, line is greatly shortened, line produced about 90% lower power consumption. 110KW fan 300 meters installed when the line loss of power day is around 10 degrees, a year is about 3600 degrees, a kiln fan according to the 600KW capacity calculation, is mounted proximate a year can save about 20000 degrees. Large ceramic factory several or dozens of production line, annual line loss of power can be reduced by hundred thousands of yuan.
