1: Steam boiler steam pressure the higher the better selection pressure, depending on the user's requirements. Vapor pressure, safety pressure member Advantageously, the energy consumption is low; but the steam will be relatively worse quality, low enthalpy, humidity, may be difficult to meet the disinfection, sterilization, culture, heating and power needs. And the high vapor pressure, energy consumption is high, the corresponding steam equipment, piping and valves the pressure is high, the maintenance requirements are also more, the production of steam, the heat transfer process, a large leakage loss. Meanwhile, high-pressure steam as the steam pressure is increased to carry the increased salinity, so salinity these waterwall tubes, pipe tobacco, and other drum heating surface fouling, overheating, foaming, clogging even increase the possibility of squib. Salt steam to steam turbine flow area will decrease, reducing the efficiency and seriously affect the heat transfer. Thus, fireman must operate in accordance with operation of the steam pressure, the steam pressure fluctuations generally allows a value between 0.05 ~ 0.15MPa.
2: the higher the boiler water level was considered safe water level is higher, the boiler water is not easy, security is also guaranteed. In fact, this is a misconception, the water level is too high, steam and humidity increase, poor steam quality, steam equipment will harm and production results. Industrial boilers, a moisture vapor sterilization or incubation with a large amount of steam also increased salt, or culture for a long time ranging from sterilization, steam consumption increase, ineffective, decreased production culture; weight is not reached the purpose of disinfection or cultured biological products contaminated scrap, even pipes, water hammer occurs apparatus. For utility boilers, steam moisture capacity, the steam turbine last stage blades will be erosion, there may appear Priming pot, water shock severe enough to cause harm equipment and personal safety. Thus, the pot water level should be maintained within a fluctuation range of ± 50mm well.
3: Some people think the better fuel plus fuel plus the more productive the greater the amount of steam. Little do they know too much fuel into the furnace, the effect will be counterproductive. When a certain amount of air and the excess amount of fuel, the furnace will produce a large amount of incomplete combustion, resulting in energy waste. People often see the dark furnace flame, weakness, and black smoke chimney, mostly for this reason. In severe cases, there will be fire pulverized coal, oil furnace secondary combustion occurs, burst pipes until shutdown. Therefore, the ratio of fuel and air volume should be adjusted appropriately, typically by looking at the fire, smoke color look, see table indicates the amount of oxygen determined. When the flame in the furnace as a bright yellow, pale gray smoke chimney to take, stable vapor pressure, wind coal showed appropriate ratio, good combustion.
4: Dial stirring the fire, the better the fire is commonly used in industrial boilers manual method. By stirring the fire, can be eliminated crater, reduction furnace from the fire and the fire bed smooth, homogeneous combustion, strong. But too much stirring the fire, but will reduce the overall thermal efficiency; this is because when stirring the fire, a lot of cold air into the furnace, reducing the average temperature of the furnace section of the flame. At the same time, increase the heat losses, an increase in the number of black smoke chimney, pollution of the environment. In addition, when stirring the fire, the staff is also susceptible to flame radiation, burns, fire-resistant layer is also susceptible to dial hearth fire damaged tools, increased furnace building maintenance workload. Therefore, the fire should be allocated as needed, to minimize the appropriate dial.
5: the bigger the better furnace pressure and furnace pressure is reflected in one of the boiler combustion conditions is normal or not an important parameter. Operating the boiler furnace negative pressure should be maintained between 10 ~ 20Pa, too great a negative pressure results in: increased leakage furnace, heat losses increase; wind increased electrical energy consumption; fly ash increased the wear along the heating surface; reduced the furnace heat of combustion efficiency. Most gas-fired boiler designed to run slightly positive pressure to increase the combustion rate. Operation, the furnace pressure becomes positive, even increasing the wind is still difficult to maintain the chamber negative pressure, said system failure or the wind furnace wall tubes, superheaters and other soft drinks leakage; fire furnace, the furnace pressure is first reflected table violent swing to the negative direction flung head. Therefore, the furnace pressure must be run according to the provisions, or should pinpoint the cause.
6: sewage longer the better spoken here regularly refers only to the sewage discharge rather than continuous blowdown. Periodic sewage mainly refers to the existence of negative bottom of the boiler slag, dirt and corrosion products, reduce furnace tube fouling, prevent clogging and reduce the salt content of the water boiler, heat transfer enhancement effect. One would think that the longer the discharge time, impurities will be discharged bottom of the pot the more, the better sewage, it is not. Sewage long time, a waste of a lot of heat, affect heating steam pressure; two pairs of boiler water circulation unfavorable, water wall tube burst will occur in severe cases. Thus, the sewage must be periodically according to "ground discharge, the discharge less uniform row" principle, provided hand operation. General Provisions at least once every eight hours of sewage, sewage each time shall not exceed 30s, overtime is strictly prohibited.
Steam boiler pressure gauge and hydraulic accumulator Henan fast boiler's automatic condensing 5000kg steam boilers price introduce small series with a pressure gauge and hydraulic accumulator steam boiler pressure gauge should pay attention to: 1, rated steam pressure of less than 2.45MPa steam boiler , not only the accuracy of the pressure gauge to 2.5; rated steam pressure 2.45MPa promoter or equal to a boiler, the pressure is too spread made not less than 1.5. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, the working pressure is usually 1.5-3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.Free Chat
