Thanks to energy supply and price advantage of coal, coke, metallurgy, electric power and other coal industry, the rapid rise of the formation of Shanxi coal-based economies of resource-based industries.

Shanxi Province, but had coal and Xing, but also because of the coal and sleepy. According to the report, "2017, Shanxi Province, coal accounted for the proportion of energy consumption up to 84.6%, higher than the national average of 24 percent, it is 2.9 times as much as the global average of Shanxi to 1.6% of the national land area, consuming about 10% of national coal amount. for Shanxi, winning the battle of blue sky, coal pollution can be effectively controlled is the key.

According to the "Blue Sky Battle Shanxi three-year action plan," issued in July this year (hereinafter referred to as "" Shanxi three-year action plan '') planning requirements, by 2020, sulfur dioxide, total nitrogen oxide emissions are lower than in 2015 more than 20%, compared to strive average concentration of sulfur dioxide in 2015 fell about 50%. Among them, 2020, total coal consumption in 8 cities in key areas to achieve negative growth, the province's coal consumption in primary energy consumption share dropped to 80%, the proportion of the province's coal consumption of coal accounts for more than 55%.

According to Shanxi Province Bureau of Statistics latest data, as of the end of August this year, Shanxi Province, the outgoing power 50.67 billion kwh, up 21.1%; the first half of Shanxi new energy consumptive power grid to complete 15.6 billion kilowatts, an increase of 58.2%, new energy abandoned consumption fell 90.6% year on year, abandoned electricity rate fell 10.2 percentage points.

The past two years the province shut down 52 coal mines, quit production capacity 45.9 million tons, subtract coal production capacity of 9.25 million tons per year, the completion of energy-saving 18 million kilowatts of coal-fired power plants, coal-fired power plants province's average coal consumption of electricity of 320 grams per kilowatt-hour of standard coal. In the first half of this year, the province's above-scale industrial Shanxi coal industrial added value increased only 0.8%.

Pressure fired vacuum boilers prices and boiler vacuum different places which have a client recently found our quick boiler, boiler refer to the difference between the atmospheric and vacuum boilers do? To address this issue, we give a brief overview of the difference between the two. A, different security present, primarily professional vacuum hot water boiler hot water boiler, a hot water boiler internal negative pressure can achieve the purpose of rapid combustion temperature, while by changing the configuration of a vacuum hot water boiler may be related to atmospheric hot water boiler. So security is more obvious than ever. The pressure hot water boiler in good use, only in part to the use of ventilation, so particularly safe and reliable pressure hot water boiler. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, a small amount of water, repeated heating cycles required to the burner, and a large container atmospheric hot water boiler with a single opening to achieve better burner heating effect can be effectively heating the circulating water. In the hot water boiler. Thermal efficiency is higher than the vacuum pressure hot water boiler hot water boiler. . Third, the complexity of the equipment in order to ensure different vacuum, vacuum hot water boiler must be installed infrastructure series a vacuum pump, but the average hot water boiler pressure control device need not be employed to maintain the vacuum. Therefore, no complicated control equipment required personnel to operate more simple, the complexity of the boiler equipment in use also have greater advantages, meet the needs of more consumers. The two boiler is very different in the use, safety, thermal efficiency and complexity of the equipment is different, so if you want to install the boiler-related equipment, the boiler can choose different devices according to your need for hot water boiler.

New classification of new energy fired vacuum boilers prices energy boiler is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. The original meaning refers to the pot on the fire heated containers that hold water heater which places combustion of the fuel, boiler and furnace boiler consists of two parts. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. Provide hot water boiler hot water boiler is called, is mainly used for domestic, industrial production also have a small application. Boiler steam is known as steam boilers, often referred to as boiler, used for power plant, ships, locomotives, and industrial and mining enterprises. Classification many new energy boiler, the boiler can be divided according to use, may be according to the structure, the type of fuel boilers points, but also by the form of the water cycle, the pressure classification. 1, by use classification boiler: boiler can be used for thermal power boilers and heating boilers. Power boiler comprising a power station boilers, marine boilers and boiler locomotive, corresponding to power generation, marine, and locomotive power dynamic. Heating boiler comprising a steam boilers, hot water boilers, hot tube boiler, stove and the heating medium heating furnace, to give a corresponding steam, hot water. Hot air and the heating medium and the like. 2, according to the body structure boiler Category: Boilers by the structure, divided into fire tube boilers and water tube boilers. Fire-tube boiler, including vertical and horizontal boiler boiler, water tube boilers and water tube boilers including horizontal, vertical, water tube boilers. 3, according to the boiler fuel type classification: according to the type of boiler fuel classified as coal-fired boilers, upgrade technology and oil-fired boiler and gas boiler coal-fired boiler, furnace oil and gas alternative --- pulverized coal boiler, gas boiler and other dual-use . Coal-fired boiler by combustion fired boilers can be divided into layers, and in fluidized bed firing boiler chamber. The latest fuel alcohol-based fuel boiler, he will greatly reduce the pollution of coal-fired boilers on the atmospheric environment. 4, classified according to the capacity of the boiler: evaporation amount of less than 20t / h is called a small boiler, evaporation to 75t / h is referred to as large boilers, evaporation of medium-boiler referred interposed therebetween. 5, according to the boiler pressure Category: 2.5MPa hereinafter referred to as a low-pressure boiler of the boiler, referred to above 6.0MPa high-pressure boiler, a pressure called medium pressure boiler interposed therebetween. In addition, ultra-high pressure boilers, boiler subcritical and supercritical boilers. 6, according to the form of boiler water circulation Category: boilers can be classified according to the form of water circulation boiler with natural circulation, forced circulation boiler (boiler including DC). 7, by device type classifier: can be divided package boilers, boiler assembly and bulk boilers. In addition, the form wall boiler, vacuum boilers and boiler modules.

Boiler feed water is necessary to control item 1, suspension criteria: When the fired vacuum boilers price feed water of the raw water from surface water, depending on the number of suspended solids and colloidal content in water, can be selected coagulation, sedimentation and filtration techniques; when the raw water is groundwater, general just filtration, which is high iron content, increased iron manganese sand filter measures. 2, standard hardness: mainly many ways to prevent or control fouling, hardness removal, lime softening, softening agents exchange, but the most common, is the best approach to ion exchange softening effect, newer methods nanofiltration is law. 3, dissolved solids standard: When the salinity pot of water reaches a certain limit, it will generate priming, resulting in a sharp deterioration in the quality of the steam boiler. Many water quality demanding industries, such as the electronics industry and power plants and other boilers with high pressure, dissolved solids of the water has more stringent requirements. Method of reducing dissolved solids generally referred to as desalting, the main methods are: ion exchange, electrodialysis, reverse osmosis, the traditional process to use an ion exchange method, a method for updating a reverse osmosis membrane method. 4, DO standard: DO is mainly to prevent the corrosion of the furnace and the duct, the general heat deaerator, there are other oxygen chemical, electrochemical oxygen, vacuum deaerator like. 5, PH value and alkalinity boiler water standards: when boiler water is alkaline (pH 10-12), in order to make the fouling substance becomes slag to clear. Commonly used dosing method. 6, the relative standard alkalinity: primarily prevents the generation of caustic embrittlement. - scale boiler cleaning equipment, boiler feed water equipment, boiler water softening equipment, boiler desalted water softening device 7, the standard oil content: boiler water is mainly to prevent foaming, with formation of oily scale. Techniques employed degreasing water separator and the like. In cities and towns, the boiler feed water is generally tap water as raw water, drinking water according to the national standard, which turbidity is not more than 5, the total dissolved solids <1000mg / l, PH = 6.5-8.5, no oil, generally only the hardness of the boiler does not meet the standards water supply requirements, for industrial low-pressure boilers and hot water boilers, only the configuration softening process.
