At this time the sewage regularly, the water discharged from the bottom part of the circulation circuit, to discharge impurities, to ensure the quality of diesel boiler specifications water; weak and the heated circulation loop heat exchanger portion strengthened to prevent local stagnation of the water cycle, so that each of the water circulation system heating surface uniformly expanded metal member, reducing the temperature difference between upper and lower walls drum.
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.
Porous materials have always been the main sound absorbing material, such as glass wool. The structural feature of porous sound absorbing materials is that there are many small gaps in the material. When sound waves are incident on the surface of the porous material, they can enter the pores, causing vibration of the air and material within the pores. The friction and viscous action of the air converts the kinetic energy (sound energy) of the vibration into heat energy, thereby attenuating the sound waves. The experiment proves that the sound absorbing material has better absorption for medium and high frequency, and the low frequency absorption performance is poor. Fangkuai Boiler uses a sound-absorbing technology combined with a porous material, and uses a sound-absorbing panel and a muffler chimney to effectively reduce the noise generated during diesel boiler specifications operation.
Trap in the application, which varies the operating conditions, the displacement in the choice trap The heating system should be several times larger condensed water discharge than normal computing, and be chosen according to the diameter size. Evaporation of less than 4 tons of steam diesel boiler specificationss, water regulator should be installed automatically, and manual means provided with feed water controls stoker operating site.Free Chat
