Recently, the Xinjiang region issued on the overall strengthening of environmental protection and resolutely fight pollution prevention tackling embodiment, the program provides: Complete with ultra-low emissions and energy-saving transformation of the conditions before the end of 2020, coal-fired power plants. Gradually shutting down key areas do not have the conditions for the transformation of highly polluting coal-fired power plants.
Implementation of the program focus on the regional party committee, "1 + 3 + 3 + reform and opening up" work arrangements, accelerate the construction of ecological civilization system to ensure that by 2020 the basic layout of the formation of the main functional areas, land space development pattern was further optimized, the total emissions of major pollutants and the amount of energy consumption per unit of GDP dropped significantly, significantly reduced the number of heavy pollution days. Specific indicators: the region of fine particulate matter (of PM2.5) concentrations of the standard level cities not decrease by 15% in 2015, the level of urban air quality days ratio reaches 71.6%; good monitoring of river water quality of the region (or superior to class III) ratio of not less than 97.6% (national quality evaluation section 47 excellent no less than 91.5%, worse than Grade V ratio of not more than 4.28%), focus on monitoring water quality of lakes and reservoirs of not less than 71%; sulfur dioxide , nitrogen oxides, chemical oxygen demand, reduce ammonia emissions into the 2015 3%, 3%, 1.6%, 2.8%; contaminated land safety utilization rate of 98%, contamination of land utilization is not safe less than 90%; the red line accounted for ecological protection area of not less than 25%; forest coverage rate reached 5.6%.
Program has clearly pointed out, we must strictly control the total coal consumption, accelerate the use of clean energy alternatives. Study the development of the region's total coal consumption embodiments and independence - - "Kui" Ukraine - - Chang stone "of the total area of coal consumption Ukraine" reduction plan, the implementation of the target responsibility management, controlling the total coal consumption. Delineation work carried out high-pollution fuel combustion zone ban, ban the sale in the region ban on burning, burning high-polluting fuels. Increasing the use of clean energy, clean energy consumptive broaden the channels, the implementation of policies for renewable energy generation full protection of the acquisition. Promote clean low-carbon energy sources priority access. Encourage waste heat, shallow geothermal and other clean energy sources for heating. Strengthening the CBM (coal gas) utilization, in an orderly bulk coal in key areas of governance, the implementation of biogas projects.
The implementation of comprehensive improvement of coal-fired boilers. The promotion of clean and efficient coal-fired boiler, strict implementation of coal-fired boiler emission standards. The region above the county level cities and built-up area basically eliminated 10 tons of steam per hour coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal-fired facilities, in principle, to a new 35 tons of steam per hour coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers. Ambient air quality did not meet the city should increase efforts to eliminate further. Key areas basically eliminated 35 tons of steam per hour of coal-fired boilers, 65 tons of steam per hour and above all coal-fired boilers to complete the transformation of energy-saving and ultra-low emissions; low nitrogen gas boiler basically completed the transformation.
In the region the implementation of ultra-low emissions and energy-saving coal-fired power plants, encouraging "Wu - Chang - Stone" to carry off white smoke fired power plant pilot area. Before the end of 2019 to complete the "Wu - Chang - stone" "Kui - ultra-low emissions and energy-saving black" area, and Korla Ili River Valley and surrounding areas with the transformation of the conditions of coal-fired plants, in other areas before the end of 2020 - only carry out. Gradually shutting down key areas do not have the conditions for the transformation of highly polluting coal-fired power plants.
Over the next three years, the Xinjiang region will strictly implement the Plan of Action to win the Battle of Blue Sky, "the Wu - Chang - stone" "" Kui - alone - Ukraine "and other key areas as the main battlefield, promote industrial structure, energy structure, transport structure adjustment and optimization, strengthening regional joint prevention and control measures to deal with weather and heavy pollution, further clarify reduce the concentration of PM2.5, and significantly reduce the number of heavy pollution days, significantly improve air quality, enhance the blue sky happiness of the people make unremitting efforts.
Commissioning of Boiler gas boiler commissioning must be carried out after the hydrostatic test. Before commissioning, should be a comprehensive inspection of each furnace parts, electronic control devices, wiring, etc. are normal, water supply, oil furnace if opened, electrical contacts are in the set position. 1, depending on the size of the fuel consumption, the initial damper, the hydraulic pressure. 2, the power is turned on, the power switch to open the cabinet, the water pump starts furnace, (if the pump is rotated into the anhydrous, pump purge valve is opened, the air exhaust pump). 3, control checks whether the normal water level electrode. 4, check the burner operation is normal. Starter burner starts combustion when the water level rose to a predetermined level, the start of combustion is normal to observe: Start no vibration noise, stable combustion, no smoke, orange yellow flame, burning bright clear. Otherwise, to make the appropriate adjustment (refer to burner instructions). Note: The oil pressure between 0.8 ~ 1.0Mpa, after a good tune, do not easily change, oil pressure is too high or too low have an effect on burner performance life. 5, check the pressure gauge pointer swing is smooth, with or without loosening stuck. 6, whether the discharge check valve is set at the set pressure steam: Pressure controller first maximum working pressure, a safety valve is adjusted to the set pressure higher than 0.05MPa, when the furnace pressure was raised to whether the exhaust pressure setting, if exhaust , pulling the safety valve a few times, and try again, if not enough to deal with safety valve to adjust. Pressure relief valve setting: boiler rated pressure + 0.03MPa. 7, check the electrical contacts of the operation: When the pressure is raised to the maximum working pressure (not exceed the rated working pressure), should stop burning, open the safety valve blowing off steam, the pressure to a minimum operating pressure (maximum operating pressure is generally lowest set to 0.10MPa), combustion burner should be restarted. Note: When the adjustment screw should slow, especially when the pointer approaches the end, otherwise, damage the screw off the wire.
Horizontal china manufacturers automatic water tube fired steam boiler with a boiler boiler you know take you through a horizontal steam boiler Generally speaking, we use boilers have very many models, according to their different fuels of different works, there are different, the boiler itself institutions, divided into many, the Take the steam boiler, there are still sub-ordinary boilers and steam boilers of it, for this horizontal steam boiler, his characteristics is not the same. Boiler fire resistant concrete arch from ramming. After the arch low and long, and therefore good combustion, flue wings and side wall refractory material sintered brick. Boiler front wall, back wall using a common bricks. Grate air distribution reasonable, the combustion chamber is large, strong coal applicability. Adapt to all types of bituminous coal or anthracite, mixed coal. Full combustion. Since the high temperature flue gas enters the first settling chamber, and then into the wings on both sides of the stack, before the smoke box, smoke and dust so good effect. Water circulation simple, reasonable structure and components under pressure, in the case to ensure water quality, completely safe operation. Combustion equipment for the quick grate, combustion apparatus installed in the manufacturing plant, transported to the site can be directly mounted on a foundation. With a reasonable structure, compact, low consumption of steel, the boiler performance, weight, frame size and capacity of the domestic product has obvious advantages compared. It is a horizontal type boiler quick fire tube boiler, refrigerant natural circulation. The boiler drum from the heat exchange system, the left and right header, composed of the water wall, the main furnace wall with a heating surface, convection tube inner drum portion and the drum.
By burning and the like during combustion of the fuel to ensure complete combustion china manufacturers automatic water tube fired steam boilers boiling water volume electrical means at night using low power boiler water boiled and stored in the insulating state. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Thus, a low-boiling nitrogen Burner electric device is an important fuel for industrial boilers and the gas boiler, which provides power to a small power people, and daytime combustion complete combustion of the fuel. Fengtai Electric boiling water into the boiler heat recovery boiler electric boiling water, boiling water boiler and continuous electrical breakdown electric boiling water boiler. 3. The principle of the burner is to shade a portion of the fuel burned too small, a small portion of the fuel burned too light, but the high air volume 360 remains constant. Since the two partial combustion deviated from a stoichiometric ratio, the NOx is low, also called the combustion or stoichiometric combustion variation. 4. The principle of segmented flame burner flame is divided into several identical small flame, because the small flame having a large heat dissipating area and a smaller flame temperature!
