China's thermoelectric heat supply accounts for 30% of the system needs to be further improved

In the past few days, as temperatures have dropped significantly, thermoelectric companies around the country have opened up bolts to provide heat for the early winter. The combined heat and power combined heating has been strongly promoted in northern heating due to its comprehensive advantages such as energy saving and emission reduction, but it has also been widely concerned by the factors such as the change of coal heat price and the heating system model.

The reporter learned that at present, among the total area of ​​central urban heating in China, the heating capacity provided by thermal power plants has reached 30%. It is expected that during the “Twelfth Five-Year Plan” period, the central heating heating penetration rate of large-scale urban buildings in northern heating areas will average. Up to 65%, of which, the proportion of cogeneration in district heating will reach 50%.

Coal heat linkage should consider price mechanism

According to the “Analysis and Forecast Report on the Electricity Supply and Demand Situation in the First Half of 2013 in the First Half of 2013” ​​issued by the China Electricity Council, the “hot price in the northeast region has been low for a long time, and the phenomenon of coal heating price upside down is more common. With the cancellation of the key contract coal, the The price of thermal coal in regional markets such as coal has been raised, and losses in heating companies have increased.” “In 2013, heating losses are expected to be 81.36 million yuan.” Fang Rui, general manager of Guodian Bei'an Thermal Power Co., Ltd., told reporters, “In recent years, Bei’an Thermal Power The company's heating continued to suffer losses, with a heating loss of 21.84 million yuan in 2010, a heating loss of 1.92 million yuan in 2011, and a heating loss of 45.97 million yuan in 2012. The company is located in the northern part of Heilongjiang Province and has a cold climate. Meteorological data are recorded. The minimum temperature in winter reaches 42.4 degrees Celsius, and the heating period lasts for 7 months. Fang Rui introduced that the company's heating export price is 27.54 yuan / kJ (excluding tax), heating costs 37.72 yuan / kJ, unit costs upside down 10.18 yuan / kj.

Wang Jun, general manager of Inner Mongolia Huaizhuo Thermal Power Co., Ltd., also briefed reporters on their loss situation: “The price of heat for the previous heating period was 15.04 yuan/gigajoule, while the heating cost for our company was 18.3 yuan/giga. The unit margin contribution is -3.26 yuan/Jig. Heat sales revenue and heating costs are seriously reversed." "It is suggested that the adjustment of the heat price must be based on actual and historical conditions in the region, suit local conditions, take into account the interests of all parties, and according to the cost of heating." Decide whether to adjust or adjust the extent of the adjustment.” Fang Rui introduced to reporters. “Although the state has introduced a coal-fired linkage policy, in fact, due to the constraints of regional economic development and market affordability, our company is located in a coal-fired area. It is not timely or in place,” said an expert from the China Electric Power Enterprise Association in an interview with reporters. “It is recommended that relevant government departments re-assess the heat price according to the principle of cost-plus in the areas with large heat losses and implement the coal heat price. Linkage mechanism; Financial subsidies are provided to heating companies with severe heat price upside down and serious losses, to ease their operational difficulties." Supplying home "heating system

The reporter noted that on September 25, the "Regulations on Heating in Shandong Province (Draft)" submitted for review by the Standing Committee of the Twelfth National People's Congress of Shandong Province stipulated that heating shall be implemented through the integration of heat sources, pipe networks, and heat exchange stations. Household heating system.

In fact, in recent years, thermoelectric companies as heat sources have also been exploring ways to directly supply heat to households.

“In the face of slowing power demand growth and the unfavorable situation in which the unit’s on-grid power struggles to increase, we have taken advantage of the company’s geographical advantages and made every effort to ensure that it is focused on expanding the direct-supply heating market.” Huadian Energy Harbin Power Plant Co., Ltd. The person in charge introduced this to reporters. As a large-scale cogeneration enterprise, the H3 power plant will add the northern heath district of Songbei District, Science and Technology Garden District, and Xintian Community of Huashang Vientiane of Limin Development Zone into the heating range during the heating season from 2013 to 2014. 1.2 million square meters of direct supply heating area.

In addition to heat sources, urban heating networks are also an important part of heating. For a long time, China's heating and heating network project as an infrastructure facility has been controlled by the government. With the economic development and the reform of the enterprise management system, the main body of investment in thermal network projects has gradually become diversified. The reporter learned that Jiangsu Changshu Power Generation Co., Ltd. jointly established Changshu Riverside Heating Co., Ltd. with Changshu Economic and Technological Development Zone to carry out the construction and operation of heat network in the region. According to statistics, nearly 40% of thermoelectric companies invest in building and operating urban heating networks. Relevant experts said that such power generation companies and the government jointly established heat supply companies in a form that can maximize government and policy support.

"It is recommended that qualified thermoelectric companies can directly set up heating companies, reduce intermediate links, and reduce heating costs." Wang Jun, general manager of Inner Mongolia Huaizhuo Thermal Power Co., Ltd., told reporters. In this regard, Yu Gang, secretary general of the Thermal Power Committee of the China Society for Electrical Engineering, stated: "In the future development, the direct supply of heat to domestic enterprises in small and medium-sized cities should be an exploration direction."

The reporter learned that in the Huadian Group, the top five thermal power generation group, the thermal power development of 59 companies, all of which used wholesale sales of 25 companies, all adopting direct supply companies 28, both have 6 companies.

Central heating is more favored by the people

"As long as the new real estate is our heating, it is a selling point. The developer will call 'The real estate is a thermal power plant's heating!' 1 square meter can sell 500 yuan more." In the Heilongjiang Harbin thermal power company, the relevant person in charge told reporter.

Huadian Jinshan Energy Shenyang Thermal Power Co., Ltd. is planning the second phase of the project, which will solve the heating problem in the south of Shenyang's main urban area. During the "12th Five-Year Plan" period, the company's installed capacity will reach 1.14 million kilowatts, and the heating area will reach 25 million square meters. Zhao Chengming, general manager of the company, recently said that the minimum outdoor temperature in Harbin has reached minus 4 degrees Celsius, and Huadian Energy Harbin Power Plant timely prepares for heating and bolting according to weather changes, adhering to the "safety heating, value heating, intelligent heating, and harmony The concept of "heat supply" continuously strengthens the inspection and inspection of equipment to ensure the reliable operation of the heating unit and provide users with a stable heat source.

The picture shows the cockpit operator inspecting the coke oven superheater separator screen. Guo Jin Shen Lina reported that the prospect of the thermoelectric company was somewhat excited: “This is to give us the people's livelihood in the Shenyang city.” This year's heating season, Northern Union Electric Power Co., Ltd. has a total heating area of ​​71 million square meters. Based on the new heating capacity of 7.8 million square meters. This is the fourth year the company has expanded its heating area.

The reporter learned from the investigation of some thermoelectric enterprises in the Northeast that the central heating of CHP is being favored by the people in a wide range.

During the “Twelfth Five-Year Plan” period, the Ministry of Housing, Urban and Rural Development will also organize the central heating of cities above the prefecture level in 15 provinces, autonomous regions, and municipalities directly under the central government, and county-level cities with a central heating area of ​​more than 1 million square meters in northern heating areas. The transformation of the old pipe network, the "planning of the old pipe network for urban district heating in northern heating areas" will be fully implemented. The transformation of the old pipe network has greatly promoted the development of central heat supply for cogeneration.

The reporter noted that "cogeneration heating" is the key to the related policies of the national environmental governance in the past two years. The Air Pollution Prevention and Control Action Plan recently issued by the State Council has also been repeatedly mentioned. “By 2017, except for the necessary reservations, basically 10 million tons of coal-fired boilers per hour and below will be eliminated in built-up areas at and above the city level, and coal-fired boilers with an average capacity of less than 20 tons per hour will be prohibited. Other areas do not, in principle, Build a new coal-fired boiler with less than 10 tons of steam per hour.” These requirements in the Air Pollution Prevention and Control Action Plan provide opportunities for the development of central heat supply for combined heat and power in northern heating areas.

The definition and classification of engineering plastics is a specific name.Engineering plastics broadly refers to plastic which has high performance and may replace metal materials.The narrow sense refers to the strength and heat resistance of plastic (PE, PP, PVC, ABS, etc.), which can be used as a structural material for industrial use and has the functional structure of high performance plastic

Plastic can be divided into two main categories: thermoplastic (after heating and melting) and thermosetting (after heating and turning into a three-dimensional structure).Engineering plastics can also be divided into special engineering plastics and standardengineering plastics.

The so-called  engineering plastics plastics often refer to thermoplastic polyamide (PA plastics).Polyoxymethylene (POM plastics), polycarbonate (PC plastics) and so on , and special engineering plastics often refers to other than the above five kinds of more excellent performance engineering plastics.According to the using temperature points, generally use temperature at 150 ℃.The following is a standard engineering plastics (generally is 100 ℃--150 ℃), more than 150 ℃ for special engineering plastics, special engineering plastics is divided into 150 --250 ℃ class (including the standardengineering plastic compounds) and above 250 ℃.The higher the temperature, the higher the price.

Characteristics of engineering plastics(compared with metal materials):

1.Advantages:

(a) small proportion: 1.0 -- 2.0, about one sixth of iron, reducing the weight effect;

(b) good processing and high production efficiency;

(c) water resistance and chemical corrosion;

(d) the friction coefficient

(e) can be colored freely;

(f) easy to compound with Glass Fiber and various filler;

(g) excellent electrical insulation;

(h) excellent heat insulation, with thermal conductivity of about 1% of iron and less than two thousandths of copper;

(I) reduce costs, save resources and energy.

2.Disadvantages:

(a) low heat resistance and low softening point;

(b) the mechanical strength is low and the tensile strength is generally about one-tenth of the steel;

(c) the dimension stability is poor and the linear expansion coefficient is about five times that of steel;

(d) poor durability. Prolonged exposure to gravity is susceptible to fatigue, and prolonged exposure to ultraviolet radiation is associated with lower performance.

3. Application of engineering plastics

(a)One is the functional components of strength, drug resistance, abrasion resistance and other requirements.The other is mechanical parts with shrinkage, dimension accuracy and appearance.Generally speaking: the former is crystalline engineering plastics, the latter is non-crystalline engineering plastics.The practical application often requires the performance of both.Engineering plastics with glass fiber (GF) or carbon fiber (CF) are more suitable for such requirements.

(b). More than half of the applications in engineering plastics are automotive and electronic, while the main use of standard plastics is extrusion molding (51%) and non-industrial products (21%).
