How to solve the air pollution problem caused by food processing price water tube boiler with operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
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.
Gas hot water price water tube boiler with manufacturers how to select gas hot water boiler manufacturers how to choose? Since the boiler more extensive applications, so the boiler market there have been many large and small boiler manufacturers. Then, hot water boilers, for example, on how to choose a good editor gas hot water boiler manufacturers express their personal opinions. (1) production plant gas hot water boiler boiler to judge the quality of a good or bad, the first thing to consider is the actual situation of its production plant, which want to have a reasonable judgment, it is recommended to plant site visits, including its production processes, technology, quality and other accessories, as well as tests before leaving the factory and so on, need to be rigorous investigation, saying only boiler from production to take every step according to standard factory, we can produce truly meet the wishes of the user high quality boiler. Under the relevant parameters (2) gas hot water boiler general, speaking for gas boilers, boiler fuel consumption is more concerned about customers, operating thermal efficiency, the use of electric power, water area, etc., then these parameters is a measure the key boiler whether it is worth buying the lies. (3) gas hot water boiler manufacturers of word of mouth a good boiler manufacturers, there are strict requirements on the self-boiler quality and service standards to customers, boiler manufacturers like customer confidence and its own brand of natural not bad, then it also must go through quality checks at each boiler. In short, a good gas hot water boiler manufacturers measure, not only from the technical and quality checks, while in sales, after-sales team also needs to have a relatively stringent requirements of the standard, interconnected, create excellent brand boiler, Being a good gas hot water boiler manufacturers.
Electric power operation a steam price water tube boiler with steam boiler flame condition is a kind of power for energy conversion from electric energy into thermal energy, the hot water or organic heat medium (HTF) is heated to a certain parameters (temperature of the boiler through the heat exchanger portion, pressure) and externally output has a nominal thermal Machinery working fluid. The use according to electric boiler can be divided into: KS-D electric water boilers, CLDR (CWDR) electric boiler (including an electrical heating bath boilers and electric boilers), LDR (WDR) electric steam boiler. Electric steam boiler in the process of running, fireman personnel to observe the combustion flame, burning flame can burn if fully reflect fully, a number of other accessories such as whether there is a problem, then the fireman can be carried out according to the boiler combustion flame swap, in order to reach the normal combustion. If the flame exhibits electric steam boiler combustion yellow-orange, with neither white nor black smoke bright and clear outline, surrounded by non-sparking, fire smoke color other than transparent; size and shape of the flame at high fire to substantially fill the chamber but the phenomenon of flame swept and peripheral heating surface does not appear. In the case where the oil temperature, oil pressure requirements are met, such as the Mars entrained in the flame, it is possible that nozzle clogging. When the atomization uniform, the local flux density is too large, the presence of coarse particles or droplets, can see the flame root few black stripe, snow flake peripheral flame Mars large droplets combustion. If there is incomplete combustion of carbon black and outer combustible gas flame, the flame and smoke in rewinding the tail and around the flame, smoke opacity. Here the air volume should be adjusted, with the wind flame-inspection position of the disc, to remove the nozzle may hit coke.Free Chat
