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.
In South America，all the customers are very impressed with our ZBG boilers, Because all of our boilers certificate by ASME, This is why Our double drum water tube boiler are favored by South American customers.
Superheater tube boilers and boiler superheater its two operating state, if the squib phenomenon, then what specific reasons? And what is the dry and wet operation of the boiler? The main purpose of the two issues raised, in order to be a good and comprehensive solution, so we will be able to have a thorough understanding of, and at the same time, let's deepen their understanding of the boiler. Cause Analysis 1. Boiler Superheater tube. Boiler, if superheater appear squib phenomenon, its specific reasons, the analysis and summary boiler manufacturer box boiler, the conclusion is: One reason: superheater tubes, long-term operation in the over-temperature condition, even if overtemperature modest, but also the mechanical strength of the pipe material will be lowered, and so the creep speed, then there a thick bulging phenomenon, until the burst. Two reasons: the presence of foreign matter superheater tube, and a blocking phenomenon has occurred, so that the boiler combustion becomes unstable, so that the deterioration of the heat transfer pipe, the local temperature is too high, and further, the high temperature squib. Dry and dry-wet operation of the boiler 2. The boiler operation: this, in block boiler manufacturer boiler opinion, is that when the boiler load is above 35%, since the generated steam boiler is larger than the flow rate of the water wall, such that the superheated steam flows through the steam trap, but this time there is no water in the steam separator, so called boiler runs dry. Wet boiler operation: For this, according to the boiler block boiler manufacturers introduced the dry run is the opposite. Which means that when the boiler load is less than 35%, less than the steam in the boiler water wall flow, then the steam separator in the water. Therefore, this condition is called wet operation of the boiler. In fact, these two states boiler can be interchangeable, and will be affected by burn rate. If the steam flow through the steam trap becomes superheated steam, together with the effect of the temperature controller, and an effective control of the boiler feedwater flow it is correct and can achieve a smooth transition of the state.
