Five combustion characteristics of gas combustion in The five main combustion characteristics of gas combustion of Fangkuai environmentally friendly gas-fired ce approved anthracite coal dhl boiler in recent years, many cities frequently occur haze, which has aroused wide concern and heated discussion in the society. China is in the period of energy structure adjustment, the task is imminent, the situation is also very serious. The energy-saving and environmental protection gas-fired boiler of Fangkuai boiler is the time to show its good energy-saving effect and excellent environmental protection ability. More and more favored by enterprises. Next we analyze its advantages from the combustion characteristics of gas fuel. Gas fuel is an efficient, clean energy source, its ignition temperature is relatively low, flame can spread rapidly to each furnace. Local, rapid combustion, easy to achieve automatic gas transportation, mixing, combustion process, mainly have the following characteristics: (1) pollution is almost zero combustion characteristics, plus basically will not produce ash, The nitrogen and sulfur contents are much lower than those of coal and oil fuels, and the amount of dust contained in the flue gas produced by combustion is also very small, which is very conducive to the protection of the environment and is basically a pollution-free combustion mode. Even the areas with the strictest environmental protection requirements can be safely used, at the same time, gas fuels are piped to transport, do not produce ash, transport, storage will not occur in the process of harmful gas leakage, dust pollution and noise pollution. (2) it is convenient to adjust the combustion. The way of transportation of fuel gas is pipeline, which can adjust the gas consumption, adapt to the change of load quickly, and realize low oxygen combustion by adjusting the valve and air valve. Thus improve the thermal efficiency of the boiler. (3) good workability. Compared with oil fuel, gas fuel is piped and supplied directly, eliminating oil storage tank, daily fuel tank and other components. In particular, compared with heavy oil fuel, save heating, heat preservation and other links. Gas system is relatively simple, operation and management is relatively convenient, easy automation. (4) easy to adjust heat. Combustion liquefaction When LPG is added, adding part of the air can not only avoid part of the explosion range, but also adjust the heat generation. (5) Gas fuel also has some shortcomings, when mixed with air to a certain proportion, it will form explosive gas. And most of the components of gas fuel are asphyxiating or toxic to humans and animals, so the safety requirements are very high. The Fangkuai boiler attaches great importance to the safety of energy-saving and environmental-friendly gas-fired boilers, and strictly guards the quality level during production and commissioning. There will be no safety accident as long as there is a code of practice in the process of use. At the present stage, China is vigorously promoting the coal-to-gas project to return the people to a blue sky. . Enterprises have responded to national policies and assumed social responsibility. Warmly welcome you to our Fangkuai boiler to buy energy-saving and environmentally friendly gas-fired boiler.
Low NOx emission combustion ce approved anthracite coal dhl boiler technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.
Leshan City, Sichuan Province issued a notice "Leshan City to win the Battle of the blue sky plan", the program made specific control measures and methods for the quality of atmospheric environment, as follows.
1, and strictly control the total coal consumption. Timely expansion of high-pollution fuel combustion zone ban scoping, year by year break down total coal consumption reduction targets. In 2020, the city's total coal consumption is not more than 7.075 million tons, accounting for primary energy consumption fell to below 30%. Strict control of new construction, renovation, expansion of coal projects, new coal project implementation year coal consumption reductions times the amount instead. Wutongqiao, multiple Qianwei existing administrative areas with coal-fired boilers, in accordance with the total capacity and operation of the boiler coal consumption reduction principle of substitution, central heating facilities in the new base construction of the park, but it must be stable ultralow emission standards, and to eliminate the heavy pollution weather and atmospheric environmental quality standards as a prerequisite for a stable schedule, bear autumn and winter peak load shifting and eliminate future responsibility.
2, to carry out comprehensive improvement of the boiler. Increased inspection efforts to prevent the resurgence of small coal-fired boilers. The city is not implemented before the air quality compliance and stability, a ban on new or expanded coal-fired boilers. Municipal Economic and Information Technology Bureau, the Municipal Ecological Environment Agency jointly entrust qualified units, the implementation of the transformation of ultra-low emissions, the use of coal industry enterprises to carry out at least once a major air pollutant emissions supervisory monitoring every year. Ban on new fuel boilers and other cogeneration coal, fuel oil. New gas-fired boiler construction simultaneously low NOx combustion facilities, low NOx combustion is completed before the end of December 2019, the transformation of existing gas boiler. City and county built-up areas the implementation of ultra-low emission biomass boilers transformation.
3, bulk coal use to carry out special rectification. Using coal for use in all high-quality coal, coal mines by 2020, all built to retain supporting washing facilities, the city's raw coal rate of 90%. In accordance with the principle of progressive advance of Pingba first, and then the mountains, the "coal to electricity," which, according to local conditions in key areas to promote rural villages, "coal to electricity, coal to natural gas" work. A total ban on the circulation and use of low quality coal, bulk coal investigate unlicensed business activities according to the law, high-pollution fuel combustion zone ban is abolished bulk coal sales outlets, to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves . In 2020, within 30 km surrounding county town and township range of the main city of almost no bulk coal use.
4, accelerate clean energy alternatives. The implementation of "gasification of the city, alternative energy, clean alternative" projects, subsidies to change the electric boiler. 2020 non-fossil fuels in primary energy consumption should increase to more than 38%. Research to develop new energy truck traffic right of way, to encourage policies on sustainable management, new and replacement buses, rental, sanitation, postal services, commuter, logistics and other light vehicles with electric vehicles. By 2020, postal services, urban delivery, light sanitation basic vehicle for the electric car, for the van passes light logistics vehicle essentially electric cars, buses central city using all new energy vehicles and reached the country six emission standards for natural gas clean energy vehicles.
