gas hot water boilers for 78 apartments

To build greener homes, recently, the ecological environment of the Office of Hebei Province issued "on improving air quality guidance on the implementation of regional differentiation of access environment." "Opinions" clearly states: Shijiazhuang, Baoding and other eight cities as a red zone atmospheric transmission channel, a ban on new industrial projects and expansion of 10 large iron and steel, thermal power, cement and so on.

"Opinions" also pointed out that the province's administrative regions and the municipalities and districts male An District, Dingzhou City, Xinji City administrative area, is strictly prohibited new construction, expansion (except for cogeneration and the same amount of alternative projects) coal; a ban on new , expansion of production capacity of iron and steel, cement, plate glass, petrochemicals project (excluding off-site relocation of upgrading) and 35 tons of steam coal-fired boilers; prohibit new emissions intensity below the access conditions of other industrial projects.

Handan, Xingtai, Shijiazhuang, Baoding, Langfang, Tangshan, Dingzhou, classified as a red zone xinji atmospheric transmission channel. Within this administrative area (except city back removal capacity), to prohibit new and expanded (except equivalent replacement) steel, thermal power (except CHP), coke, cement, lime, gypsum, fertilizer, general casting of ferrous alloys, iron alloys smelting, carbon, other industrial projects using coal as a fuel; Jing Kun high-speed east, north wing black high speed, and Langfang, Baoding and Beijing bordering county area designated as coal ban areas, not in addition to the approval of central heating coal-fired project.

Future, Hebei Province, will strengthen self-examination, government oversight and something in the ex post regulation, the implementation of various construction projects of environmental protection requirements as well as changes in environmental quality, pollutant emissions such as the implementation of dynamic monitoring of the implementation of environmental access requirements for non-construction strictly punished according to the law project, supervise the rectification of the problem is serious, shut down or banned. Meanwhile, according to relevant laws and regulations, environmental protection requirements and regional environmental quality changes and other regional differentiation environmental access requirements will be adjusted in due course.

The reason you must know the problems of energy consumption boiler (boiler exhaust gas temperature) produce exhaust gas temperature of the boiler problem (1) shift the center position on the furnace flame, the exhaust gas temperature rises a multi-burner into the upper interlayer with the wind unreasonable . b upper stoker coal excessive. c burner tilt position shifted, resulting in the shift of the center position of the flame. d burner auxiliary throttle opening degree command deviations, lack of oxygen, pulverized coal combustion delayed. e a high-pressure fan outlet, wind speed is too large, the pulverized coal combustion furnace into the shift position. f leakage boiler, the furnace excess air factor export. g coal is too thick, ignition and slow combustion reaction. h low volatile coal, high ash, high moisture, ignition difficulties, to delay the combustion. i mill outlet temperature is low, the air entering the furnace temperature was lowered powder mixture, combustion delay. (2) When the boiler "four leak" for plugging, resulting in a superheater, reheater or economizer to reduce heat transfer area. (3) the supply air temperature is high. (4) high flue gas dew point temperature. (5) soot blowing equipment investment is not normal. (6) heating surface coking, fouling. (7) The air preheater ash fouling, heat transfer efficiency is lowered. (8) strict quality control, internal heating surface junction. (9) low water temperature.

Boiler is how the classification? Press export steam parameters of how to classify? Classification of the boiler is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5

25MW CFB boiler used for co-generation has the advantages of water saving, power saving, no clean gas reheating necessary, no need for special materials for corrosion protection and so on, it has excellent technology-economy, especially in flue gas desulfurization projects of large-scale and low-sulphur coal fired power plant units or at water deficient areas.
