Shanxi Province is located in China's western areas north of the Loess Plateau, the terrain finished solid, rich products. Thanks to energy supply and price advantage of coal, coke, metallurgy, electric power and other coal industry, the rapid rise of the formation of Shanxi coal-based economies of resource-based industries.
Shanxi Province, but had coal and Xing, but also because of the coal and sleepy. According to the report, "2017, Shanxi Province, coal accounted for the proportion of energy consumption up to 84.6%, higher than the national average of 24 percent, it is 2.9 times as much as the global average of Shanxi to 1.6% of the national land area, consuming about 10% of national coal amount. for Shanxi, winning the battle of blue sky, coal pollution can be effectively controlled is the key.
According to the "Blue Sky Battle Shanxi three-year action plan," issued in July this year (hereinafter referred to as "" Shanxi three-year action plan '') planning requirements, by 2020, sulfur dioxide, total nitrogen oxide emissions are lower than in 2015 more than 20%, compared to strive average concentration of sulfur dioxide in 2015 fell about 50%. Among them, 2020, total coal consumption in 8 cities in key areas to achieve negative growth, the province's coal consumption in primary energy consumption share dropped to 80%, the proportion of the province's coal consumption of coal accounts for more than 55%.
According to Shanxi Province Bureau of Statistics latest data, as of the end of August this year, Shanxi Province, the outgoing power 50.67 billion kwh, up 21.1%; the first half of Shanxi new energy consumptive power grid to complete 15.6 billion kilowatts, an increase of 58.2%, new energy abandoned consumption fell 90.6% year on year, abandoned electricity rate fell 10.2 percentage points.
The past two years the province shut down 52 coal mines, quit production capacity 45.9 million tons, subtract coal production capacity of 9.25 million tons per year, the completion of energy-saving 18 million kilowatts of coal-fired power plants, coal-fired power plants province's average coal consumption of electricity of 320 grams per kilowatt-hour of standard coal. In the first half of this year, the province's above-scale industrial Shanxi coal industrial added value increased only 0.8%.
When gas boiler ignition, need to pay attention to what matters is the primary determinant of the ignition gas boiler started to master boiler ignition precautions to ensure the safe and stable operation of the boiler. 1, for gas-fired boilers, the ignition time if not successful, the need to purge the furnace flue, before a second firing. 2, in order to prevent a gas explosion, gas boilers not only to purge the boiler furnace and flue gas channel before the start, the need for a purge gas supply pipes. The gas supply duct media typically purged with an inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace flue with a certain flow rate is the flow rate of air. Case 3, in the rear of the boiler did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case. 4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, it is necessary to detect smoke components, to avoid too high excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.5 , real-time attention should fireman switch case of a gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valves, only put into operation is determined normal. 6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion. 7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close air release valve. 8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, should contact the gas company. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter. 9, should comply boiler unit boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. When there are unusual circumstances and can not solve the problem, depending on the nature of the problem promptly contact boiler plant or gas company, to conduct maintenance by a professional maintenance staff. 10, shall comply with the provisions of the relevant gas. Not free to fire the boiler room, prohibited welding, gas welding and other operations in the gas pipe roadside.
ZG circulating fluidized bed boiler hot water boiler can be interior decoration, but also can open layout, could burn anthracite, bituminous, lignite and coal and other relatively low calorific value fuel, fuel burnout rate is up to 99%, energy saving and environmental protection effect is evidently.
Gas-fired boiler installation process: after the user bought gas boilers, installation is also a priority. Master the correct knowledge boiler installation, boiler in order to avoid problems appear after the late stage.
