Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam boiler steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).

Fuel gas-fired boiler is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory.

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.

Pressure fuel boilers interpretation of the overall daily operation and maintenance of oil-fired boilers with atmospheric corrosion knowledge structure, including boiler and auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler pressure fuel daily operation and maintenance link and chemical corrosion, turbine attendant prepare enough desalinated water, oxygen, water passing temperature no higher than the drum wall temperature 50 ℃; Sheung during hot drum wall temperature should be after the temperature of the metal is not more than 40 ℃ before a new installation or repair departments boiler Feed records an indication of expansion. Sheung summer time less than 2 hours, at least 4 hours in winter, when the temperature and Sheung drum wall temperature difference of less than 40 how ℃ boiler reheater corrosion protection? after turbine fight gate, boiler guarantee a blower, an induced draft fan is running the best cross retain two oil gun. turn reheaters to the empty exhaust steam reheater hydrophobic doors and air doors corrosion, anti-corrosion of the reheater steam temperature is lower than a predetermined deg.] C for 400 control drum water level within an allowable range. anticorrosive time less than 20 minutes after stopping two oil gun operation. guarantee furnace pressure when 50--100Pa, each of the flaps open, baffle for ventilation less than 5 minutes, stop sending, fan, each of the flaps closed tailgate may be appropriate to accelerate Sheung speed.
