What are the advantages of condensing specs for boiler waters as condensing boiler boiler industry a new product, which itself has many advantages make efficient use of the boiler is very high, so that the application field of condensing boilers have become very wide. In this paper, around condensing boilers to discuss, detailed analysis about why such a boiler by consumers, specific about its several advantages. First, energy saving, environmental condensing boiler uses a metal fiber surface of the premix combustion mode, such combustion can be thoroughly mixed prior to combustion of air and natural gas in accordance with a certain proportion, the mixed gas can be sufficiently done burning, so it will not because of the presence of residual and waste of resources. In such a case, the combustion process in the condensing boiler, capable of effectively reducing the generation of polluting gases to meet environmental requirements. Second, high performance, low noise condensing boilers because of the design to be occupied by small location, using multiple linkage control operation, the operation is very simple. Built-condensing boiler burner, while the boiler flame combustion micro belongs, so that only a very small sound generated during combustion, so that flue can reduce noise, and the use of a low-noise blower fan, can be done from inside the boiler perform acoustic treatment. Third, long life, high efficiency condensing boiler made of aluminum silicon, antioxidant, scale special waterproof treatment, a long service life. While condensing high-efficiency heat exchanger boiler design, large heating area arranged, condensation latent heat recovery technology, and the small volume of water, high thermal efficiency. Fourth, safe, stable to run at a condensing boiler domestic gas pressure, and may be shared with a cell gas supply system, without opening fee, pre-condensing boiler technology fully premixed air and natural gas, air-fuel ratio will not improper deflagration, intelligent multi-interlocking control, instructions misfiring does not occur. Several advantages of the above points is condensing boiler is located, it is the presence of these advantages, which makes condensing boilers can be recognized by consumers and welcome in many areas. Of course, as a professional condensing boiler, it has the advantage very much, the article is only introduced a few of them, condensing boilers need to get real experience in use.
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.
