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.
Gas commercial 4t boiler supplier jordan room gas leak serious harm to the increasingly tense in recent years as the price of coal and coal supply more of our day to rise, more and more companies turning to heating gas heating from conventional coal-fired heating, gas supply heat its environmental protection, energy conservation in the country has been more widely used, especially gas central heating boiler room the most popular. So gas boiler room safety management has also become an important issue in the heating industry attention. In recent years, Nansen boiler room with heating company EMS / OSH / HSE management system as the carrier continued analysis of hazards and risks boiler room gas leak, the development of effective preventive measures, the use of a number of advanced new technologies at home and abroad, new technology and new equipment to ensure the safe and stable operation of the boiler room. The main component of natural gas we use are: methane content 98, the content of 0.3 propane, butane content of 0.3, 1 and the nitrogen content of other substances, high calorific value 9650 kcal / standard side, the low calorific value 8740 kcal / standard side, explosion limit: 5-15. We call regional gas may leak means natural gas pipeline, a valve table, fitting between the regulator from the station to the boiler (including boilers) and the like. Wherein the regulator station for the fan to between buried pipeline between the boiler to fan out to the overhead line. Gas explosion in an instant, (the number of thousandths of a second) the production of high-temperature (up to 3000 deg.] C), high-pressure combustion process, explosion velocity of up to 300m / s, resulting in a great destructive power. If a natural gas leak encountered fire, static electricity, lightning or improper operation such as an explosion, a fire in a confined space will make people hypoxia, asphyxia and even death, to production safety and the state and the people incalculable loss of life and property .
6 tons adjusting a combustion gas steam commercial 4t boiler supplier jordan, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
The greenhouse oil and gas commercial 4t boiler supplier jordans produced by ZG boiler have wns series boilers and SZS series oil and gas boilers. These two boilers are fast-assembly installation oil and gas boilers. The boiler body is small, occupying a small area, convenient operation and sufficient output. Oil and gas boilers use natural gas, petroleum and other fuels, fuel delivery is fast, and there is no ash residue after fuel combustion. The greenhouse oil and gas boilers produced by ZG boiler are very environmentally friendly. They adopt advanced low-nitrogen technology to achieve low-nitrogen emission from boilers, and the boilers are clean and clean. It is an environmentally friendly boiler.
