For winning the Battle of Blue Sky, Jiuquan City, Gansu Province, issued in 2019 action to implement the program, which requires: accelerate the implementation of the transformation of ultra-low emission thermal power and other key industries. Details are as follows.
First, in an orderly clean heating in winter
Seriously implement the "clean Gansu winter heating overall plan (2017-2021 years)" and "clean Jiuquan City winter heating embodiment (2017-2021 years)", combined with the overall urban planning and development of real priority to the development of central heating and accelerating focus heating pipe network construction and transformation progress, and constantly improve the urban central heating cover, reduce civil bulk coal usage, central heating difficult coverage areas, speed up the implementation of all types of decentralized clean heating.
Second, the full completion of the comprehensive improvement of coal-fired boilers
And by phasing out the demolition, clean energy transformation, environmental compliance management, etc., complete with coal-fired boiler remediation tasks. Increase efforts to eliminate small coal-fired boilers, the county level and above urban area (high-tech zones, except through the open area, industrial parks and industrial agglomeration area) basically eliminated 10 tons of steam per hour and coal-fired boilers and furnaces tea, operational stove, grain storage and drying equipment, coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers.
Third, strengthening the total control and the clean use of coal
Issued according to the provincial total coal consumption control objectives and annual coal consumption indicators, strengthen coal total control. New coal coal project implementation reduction alternative, reduce the proportion of coal in energy consumption, improve power coal in total coal consumption in proportion.
Fourth, accelerate the development of clean energy and new energy
Gradually increase the proportion of non-fossil energy consumption, the orderly development of hydropower, optimizing wind, solar energy development layout, coupled encourage the promotion of coal-fired biomass power generation, local conditions to develop biomass energy, geothermal energy, to ensure that by 2020, the city's non-fossil fuels in energy the proportion of total consumption reached 20%. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem.
Gas-fired steam wns horizontal fuel boiler and gas steam boiler at any time there is any good compared to the country more and more attention to environmental protection, gas steam boiler has been a great blow, and relatively gas steam boiler by many users of all ages, in recent years, the country also strongly promote the use of gas-fired boiler, gas steam boiler then compared with the gas steam boiler what good is it? And today we work together to explore. Gas-fired steam boiler steam boiler and gas each accounted for half of the market, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of the gas boiler, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, the price of gas than the gas boiler boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more gas steam boiler, the boiler room in the building have a little more money. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The gas-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than the gas burned per hour for much more. 4. environmental costs: in the need to protect the environment, review the current gas boiler more strict. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used.
Advancing the ignition point of coal, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the wns horizontal fuel boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.
? First: to improve fuel will be coal into gas in principle, more in line with the standard requirements of the relevant countries, fueled by coal wns horizontal fuel boiler has been subject to strict national authorities to stop, that there is often a boiler in the enterprise will fired boiler into gas boiler rehabilitation programs embodiments, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second: the furnace to improve coal-fired boiler furnace into a gas furnace is the use of coal-fired auxiliary boiler for heating the furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion gas gathering hearth or tail, it is very prone to catch fire or explode, so then you need to hearth to improve device blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third: When ancillary equipment prior to improvement has not improved during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate, etc. followed by boiler using these accessory devices do not need to use a gas stove, so you can save and invest more of boiler equipment. Fourth: to improve the degree of environmental protection we all know has been a coal-fired furnace is not allowed by the national environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, adopted after performing boiler gas furnace and greatly reduce emissions of soot and various dust can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with national standards of environment protection and energy policy.[email protected]
