What does the Fangkuai boiler tell you about instrument activity analysis? What is the effect of instrument activity analysis? The operation of the boiler is reflected by the instructions of various instruments. According to the indicator data of the instrument and its changing trend, it is the analysis of the instrument activity to analyze whether the boiler's working condition is normal or not. The normal operating parameters of the boiler are measured by various thermal monitoring instruments in various parts. The vehicle data include pressure, temperature, flow rate, water level, current, etc. In normal operation, by monitoring the operation of these parameters, we can analyze and judge the operation condition of the passageway, and when the accident occurs, we can also pass the Abnormal data changes to analyze and judge the location and nature of the accident, this timely handling of the accident to create conditions. The surge of induced fan is due to the excessive differential pressure in the inlet and outlet of its static blade. The differential pressure of the inlet and outlet of the stator blade is influenced by the resistance of the pipe, and the same induced fan is more prone to surge when the resistance of the static blade opening pipe is large. The static blade opening of the induced fan produces the corresponding wind pressure and flow rate. When the pressure and flow rate produced by the fan are greater than or equal to the resistance of the flue gas pipe, the fan can work stably without surging. When the resistance of the pipe increases, the pressure flow at the outlet of the fan can not overcome the resistance of the pipeline system. The force reverses the current. When the pipe resistance is reduced to the fan outlet pressure, the flue gas flows downstream. The smoke flows back and forth in such a way that it is surging. Therefore, when the resistance of wind-smoke pipe is large, it is more prone to surge when the output force is not enough. The influence of starting and stopping pulverized coal production system on boiler combustion condition is analyzed. As a result of the three-time air belt powder, the furnace fuel quantity increases / decreases, and the oxygen content increases / decreases relatively when the pulverized coal production system is started / stopped. When the pulverized coal making system starts for a long time, the boiler flame length is long, the furnace fire filling degree is good, and vice versa; under low load, the multiple pulverizing system operates or completely stops the pulverizing system, especially to prevent the flame from suddenly extinguishing. Once What is the cause of duct clogging? How to prevent it? Reasons: 1) the burner is blocked by coke or the inlet of the burner is partly blocked by small oil gun. 2) too many impurities in pulverized coal, too high speed of pulverized coal feeder, too heavy pulverized coal and too low primary wind speed. 3) the speed of powder feeder is too high. Too much powder to blow away in time. 4) the wind pressure is too low once (the wind door is not open or the opening degree is too small), do not take away powder. Preventive measures: 1) according to the speed of the powder feeder and the load of the unit, the corresponding primary air pressure should be adjusted in time, the speed of the powder feeder shall not be greater than 700 rpm, the primary wind speed of each unit shall be kept at 25 ~ 30 m / s, and the mixing temperature of the primary air and powder shall be controlled at 180. At ~ 250 ℃, the primary wind pressure depends on the load and coal quality, and the range of variation is in the range of 2.5~3.8kPa.2) it is found that the primary wind speed is too low. When the primary air temperature is lower than the normal value, the primary air velocity and the primary air temperature corresponding to the speed of the powder feeder should be reduced in time. 3) the boiler oil tank stop powder feeder should fully blow the tube. Blow away the powder from the powder tube. 4) scorch or clog the fire nozzle and try to get rid of it. Which causes the induced fan vibration? 1) motor bearing oil shortage, resulting in bearing wear and vibration; 2) coupling installation center is not good; 3) induced fan stall surge; 4) induced fan ground angle bolt Loose; 5) blade ash or wear, out of balance.
To effectively and efficiently solve air quality problems, further improve people's quality of ambient air, Luliang city government issued the "Luliang city and surrounding tackling air pollution control action plan."
Luliang within the range of 1300 square kilometers around the city, "an area three counties' area under the jurisdiction of section: Lishi District, Riverside street nine township (town, street) a total of 54 villages; Luo Zhongyang County town of 12 gold villages; Liulin County, Lee Wan total of four villages; Fangshan County Dawu town a total of 11 villages.
1, the effective promotion of clean heating.

2, bulk coal coal strengthen supervision. Downtown "ban on coal zone" expanded to 88 square kilometers, the Willows, in the sun "and ban on coal zone" for the county built-up areas and the surrounding area 5 km, Fang Shan range "ban on coal zone" for the built-up area region, 2019 August 31, coal stoves and coal "double clear" within the scope of "no coal zone" implementation. "No coal zone" outside the prohibited than 1% sulfur, 16% ash content than coal for civilian. Determine civil bulk coal sales to crack down on low-quality coal sales practices.
3, to carry out comprehensive improvement of the boiler. 2019 August 31, all workers in the region (companies) industry, commerce, services, basic administrative units out of 10 steam tons / hour and coal-fired boilers, combustion zone ban (ban on coal zone) all residents within the range, all the villagers self-built coal-fired boilers out of the cell. Not "ban on coal zone" to be able to ensure clean winter heating, self-built coal-fired boilers shall be eliminated; it is difficult to ensure clean winter heating, self-built coal-fired boilers Always use clean coal substitute. And more than 65 tons of steam coal-fired boilers to complete the transformation of energy-saving and ultra-low emissions, low nitrogen gas boiler basically completed the transformation, to achieve ultra-low emissions coal-fired power plants. 35-65 tons of steam coal-fired boilers and more particularly to achieve stable discharge standards; co-firing biomass boilers ban coal and other fuels, efficient dust bags and other ancillary facilities. Non-alcohol-based fuels to burn in the name of blended chemical waste.
