Treatment of natural gas leakage in horizontal gas low cost china quality coal fired boiler room

According to relevant data, with the speeding up of changing coal to gas, the project that change industrial coal-fired boilers to industrial gas boiler no matter in quality or quantity are growing faster. In addition to the support of national policy, the development of industrial gas boiler also benefited from the convenience of natural gas.

Recently, Yuhang District, Hangzhou, Zhejiang Province, a printing company 20 steam tons / hour of coal-fired low cost china quality coal fired boilers have been stalled, this is the last Yuhang district an industrial coal-fired boilers, which marks the shutting down of Yuhang District of industrial enterprises to bid farewell to coal energy structure of coal turned to natural gas and other clean energy, Yuhang District from entering the industrial coal-free era.

Yuhang District "coal-free zone" construction of road resistance and long. As a major industrial zone, a long time, Yuhang District to focus on coal-fired thermal power plants, coal-fired boilers and other industrial enterprises formed a coal-dominated energy consumption structure. In 2014, the maximum amount of coal Yuhang District reached 783,600 tons. Large coal consumption that emissions of sulfur dioxide, dust and the like remain high for many years.

In order to further deepen the air pollution control, to win the Battle of the blue sky, Yuhang District, from 2017, will gradually tangqi thermoelectric, thermoelectric and sea Chongxian three coal-fired thermoelectric power plant with all closed down, the sea of ​​clean natural gas for thermoelectric realized heat. 3 thermal power plant shut down so that the region's coal consumption, pollutant emissions and other indicators to achieve substantial reductions in road construction of "coal-free zone" has taken a crucial step.

Yuhang bid farewell to coal road this did not stop. While coal-fired thermoelectric accounted for the bulk of coal consumption and pollution emissions, but only out of coal-fired power plant is not enough. 2018, the government decided to promote taking advantage of Yuhang District, the region within the remaining four coal-fired industrial enterprises (Coal Products) pot (kiln) furnace closed down or eliminated or modified.

Yuhang District to increase the proportion of electricity consumption, and actively guide the region's energy unit of coal to electricity, oil to electricity, gas bottle to electricity, the construction of an orderly distribution grid, promoting smart grid construction; continue to improve the level of utilization of natural gas, and urban area in addition to all the town cormorant birds, Baizhang full realization of natural gas supply, a total of 850 kilometers of natural gas pipeline construction and municipal gas transformation 45000; to promote the application of photovoltaic power generation, the region's industrial and commercial enterprises amounted to 173 megawatts of photovoltaic capacity building distributed, clean energy applications has taken shape in Yuhang District.

According to statistics, "Thirteen Five Year Plan" (2016-2020) since the implementation of environmental statistics included in Yuhang district industrial enterprises coal consumption from 588,900 tons in 2016 down to 38,900 tons in 2018, to drop in early 2019 0.

A substantial decline in coal consumption is brought to slash emissions of pollutants and air quality improved significantly. 2018, the main pollutant urban air Linping PM2.5 average concentration of 38 micrograms / cubic meter, decreased 40% in 2015. Region sulfur dioxide emissions of 7,833 tons in 2014 to 2018 had dropped more than 90%; NOx emissions to 8490 tons in 2014 to 2018 had dropped more than 60%.

Five combustion characteristics of gas combustion in The five main combustion characteristics of gas combustion of Fangkuai environmentally friendly gas-fired low cost china quality coal fired 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.

About Henan low nitrogen gas low cost china quality coal fired boiler and the transformation of Henan low nitrogen gas boiler is upgraded on the basis of common furnace on it than the ordinary boiler biggest advantage is that the emission of nitrogen oxides. Henan low nitrogen gas boiler is divided into two: one is nitrogen oxide emissions below 80 mg; the other is a nitrogen oxide emissions below 30 mg. Of course, if you want to achieve low nitrogen emissions, it must be met is to use low-nitrogen burners. From the development trend, Henan low nitrogen gas boiler into the mainstream as a winter heating, natural gas is not only energy efficient, low-carbon environment, the country can meet the heating needs of sustainable development and environmental protection are two simultaneous, consistent with the development of the cause of energy conservation ideas , winter heating will become mainstream products in north and south China regions. In response to the national "energy saving" the call, further reducing boiler NOx emission from the country are carrying the boiler to Henan low nitrogen gas boiler. Currently, low-nitrogen transformation technology boiler there are three: First, the two-scale low NOx combustion technology, mainly for Corner Tangential unit, by controlling the scale of the transformation process and on the spatial scale to achieve three characteristic difference, resulting in two furnace three beneficial characteristics forming the anti-slag, the NOx is low, steady combustion of the scale function. Second cyclone low NOx combustion technology, primarily for the opposed wall units, by replacing coal burner and the transformation of secondary air, tertiary air boiler to reduce the nitrogen oxide content. Third W low - NOx combustion flame technique, the longitudinal arch boiler pulverized coal burner to a low NOx combustion is replacing a specific structure, to reduce the impact on the normal operation of the combustion tissue as possible, the structure of the secondary air substantially constant. These three low NOx combustion technology in the transformation have made good Jiangdan effect. Now, there are many small boiler (100MW units and below, primarily in the form of Tangential) also need to be low-nitrogen transformation, but if using conventional low-nitrogen transformation technology, investment costs are relatively high for small boiler is concerned, may not be bear, economic efficiency will also be affected. In view of this situation, we launched a small-scale low-nitrogen transformation technology boilers, control and transformation through major processes affecting boiler nitrogen oxides produced with a smaller cost of renovation to achieve the purpose of significantly reducing the concentration of nitrogen oxide emissions boiler.
