Natural circulation, the difference of the control loop of the DC condensing combination boiler biasi: Depending on the steam inside the boiler, the water flow pattern, which may be divided into three categories: natural circulation boilers and the DC control loop. Three both in common, but there is a big difference, following the fast boiler, boiler learn more knowledge.
Recently, Hangzhou Provincial People's Government for the quality of atmospheric environment issues issued a deadline for compliance plan, as follows.
First, the situation and challenges
Since the "Atmospheric ten" implementation of Hangzhou to build an ecological civilization as a guide to improve the quality of atmospheric environment as the goal, carry out air pollution prevention and control actions to protect the G20 summit in Hangzhou as an opportunity to promote a strong "coal-fired flue gas, industrial emissions , vehicle exhaust, dust gray gas, urban and rural exhaust "other" gas cohabitation ", strengthen regional joint prevention and control, air pollution control and achieved remarkable results, no built coal-fired thermal power, iron and steel producers no, no emission vehicles "three noes" urban atmospheric environmental quality continues to improve.
(A) Key Performance
1, ambient air quality improved significantly.
In the case of the national economy with an average annual growth of 9.1% of the "second five" major pollutants emission reduction achieved remarkable, sulfur dioxide, total nitrogen oxide emissions compared to 2010, respectively, decreased by 21.9%, 26.5%, exceeding the state-assigned the reduction targets and tasks.
2, energy and industrial structure gradually optimized.
The city's total energy consumption growth narrowed year by year, total energy consumption in 2015 was 39.48 million tons of standard coal, an average annual increase of "Twelfth Five-Year" period is only 3.4%, compared with the "Eleventh Five-Year" down 2.1 percentage points.
3, industrial pollution prevention deepened.
Promoting desulfurization and denitrification and dust removal facilities, coal-fired thermal power generating units are completed desulfurization, denitrification facilities, a total of 87 coal-fired thermal power generating units ultra-low emissions transformation.
4. The motor vehicle exhaust pollution prevention and continuous progress.
"Twelve Five" period, and comprehensively promote the yellow car out of work in 2015, the city basically eliminated emission vehicles.
5, comprehensively promote urban and rural waste gas treatment.
"Twelve Five" period, to strengthen the construction site dust management, the establishment of civilized city construction sites and construction dust pollution comprehensive rectification work leading group, the establishment of municipal, district, enterprise level management network.
6, continue to strengthen capacity building.
"Twelve Five" period, the construction of Hangzhou, air pollution control system for continuous improvement, introduced the "Hangzhou pollution prevention provisions of the atmosphere", and the issuance of the annual air pollution control plan and supporting the implementation of assessment methods.
(B) there is a problem
1, ambient air quality improvement into the bottleneck.
In recent years, the effectiveness of atmospheric environmental quality improved significantly, but control "Ambient Air Quality Standard" (GB3095-2012) secondary standards are still gaps.
2. Regional collaborative governance is still run-in period.
The analysis results Hangzhou PM2.5 sources, the contribution to the local discharge air in an urban environment PM2.5 concentration 62% -82%, about 72% on average. Regional transport to urban ambient air concentrations of PM2.5 contribution accounts for 18% -38%, an average of about 28%, in different seasons affect the Hangzhou area varies. A higher proportion of regional transport and complexity of the transmission source region to control air pollution in Hangzhou more difficult to establish and improve regional air pollution is critical institutional mechanisms of joint prevention and control.
3, into the deep water of air pollution control.
In recent years, Hangzhou, air pollution prevention and control work has achieved remarkable success, but there are still many "shortcomings" in the current governance of air pollution, structural, further highlights the deep-seated problems.
(1) optimize the industrial structure needs to continue, heavy pollution in some areas, high energy-consuming industries and the "messy dirty" business issues are still quite prominent.
Total coal (2) Energy consumption is still high, the use of natural gas supply capacity and scale need to be strengthened, industrial parks (industrial parks) are still blind spots of central heating, renewable energy development and utilization efforts still need to increase.
(3) heavy end of the treatment, the light source control and cleaner production, the work of "second five" major emission control measures revolve around the end of pollutants on source control and cleaner production process is still insufficient attention.
(4) With SO2, NOx reduction work continued in-depth, project emissions space shrinking, VOCs emissions is more a lack of technical means, the rigidity of the vehicle population growth, vehicles, ships and non-road mobile machinery and other mobile source pollution control to be a breakthrough. With the difficulty of the work of prevention and control of atmospheric pollution key areas continue to increase, the city is still on air pollution control into the deep water.
4, the basic work is still weak period.
Municipal government attaches great importance to air pollution control work, work-related basis more solid, but there are still many weak links. Hangzhou, organization and leadership of atmospheric pollution control systems should be strengthened, the department division of labor, the working mechanism of collaborative governance needs improvement. Local standards should be further improved, pollution resources and a list of atmospheric pollution still need to be updated regularly.
Steam quality product quality is an important reason for the decision, but also one measure of the quality of the steam condensing combination boiler biasi. Quality steam means steam boiler steam cleanliness, the total amount of impurities normally contained in the steam mass units represented; vapor contain various salts, alkali oxides and other impurities, a major proportion of the salts, the steam containing impurities caused by excessive superheater receiving surface, and a steam turbine flow duct portion salt deposition problems.
Which type of pipe is used for the steam outlet of the steam condensing combination boiler biasi? Is there a regulation for the temperature deviation of the superheated steam?
