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.

Gas boiler heating surface elements and hydraulic machine hydraulic system temperature Xiao Bian told you about the gas boiler heating surface elements and hydraulic machine hydraulic system was increased 1: heat impact: low heat, low temperature combustion theory. To ensure that the design parameters and capacity of the boiler, fuel consumption and more, the furnace outlet increases eye pattern, a large amount of smoke, and the temperature and pressure so that the heat transfer gas velocity in each of the convection heating surface are increased, resulting in convection heating surface endothermic the amount of increase. Thus, each of the heating surface area of ​​the boiler will be changed accordingly. 2: volatile Impact: coal fuel gas-fired boiler low volatile and is not easy to catch fire and burn, furnace volume heat intensity should get smaller, the larger the volume of the furnace. Flame length, the furnace should be higher. In order to ensure stable ignition of the fuel, the water wall surface of the burner arrangement Refractory laying tape, reduce heat absorption area waterwall combustor to maintain the high temperature, hot air and powder feeding hot air temperature higher, so relatively arranged much air preheater heating surface. In order to ensure the fuel burn, requires a larger excess air ratio, the combustion temperature in the furnace and reduce the amount of flue gas increases, it should be arranged to increase the convection heating surface. 3: Effect of Moisture: Water large, combustion temperature in the furnace is reduced, reducing the radiant heat absorption in the furnace, the flue gas increases the amount of heat absorption increases convection heating surface. Thus, convection heating surface required multi worth area. Meanwhile, moisture, high temperature hot air requirement, while the arrangement requires more air preheater heating surface. 4: Ash Impact: ash content, will aggravate the wear convection heating surface, in the design of the convection heating surface, should be used in low-speed cigarette or other friction reducing measures. Low ash melting point, should be used in a low heat furnace cross-sectional strength, thermal strength burner zone wall and the furnace volume heat intensity, to ensure that the back of the furnace and the convection heating surface not slagging. For low fuel boiler ash melting point, it should be employed in slagging combustion. For ash, it may also be employed multiple flue arrangement. 5: Multi sulfur, ash can cause corrosion and plugging of the low temperature heating surface, also cause high-temperature corrosion. Therefore, the design should pay attention to the selection and arrangement of the parameters of the heating surface, and take appropriate measures. As heating temperature, and contamination of the hydraulic system, but also an integrated form of the fault, the primary measured by measuring the oil temperature and a small amount of hydraulic components. Oil cooling during rotation around the start of operation to thermally. Temperature too high will produce the following faults: 1, temperature rise, the viscosity will decrease oil leakage increases, the overall system efficiency and volumetric efficiency of the pump is significantly reduced. Since the viscosity of the oil is reduced, thin film and other moving parts of the spool are cut and broken, the frictional resistance increases, resulting in increased wear, heat generation system, lead to higher temperature. 2, high oil temperature, mechanical thermal deformation, so that the gap between both the hydraulic components of different coefficients of thermal expansion becomes smaller moving member stuck, causing operation failure, they affect the precision of hydraulic equipment, resulting in variable quality parts processing difference.
