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.
As a leader in the fast side condensing gas boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
Future environment of new energy industries have competed in the development of new energy, new energy to seize the initiative. The same industry, too. Straw-efficiency boilers in experience and practice to promote new rural energy development and utilization of clean.

Henan gas boiler surroundings in claim (1) prohibition of the various stacked Henan combustible gas in the boiler room, not allowed to bake anything Henan gas boiler and steam pipes. Cotton wipe oil equipment, oil rag to a safe place. (2) prohibit incineration in Henan gas boiler waste paper, waste wood, linoleum and other waste, to avoid causing a chimney fire fly, ignite surrounding combustibles. Around (3) Henan gas boiler can not be an ignition source is not close to the other heating boiler pipeline equipment. In addition, we must pay particular attention: Once Henan gas boiler appears dry (red-hot), turn off the power immediately, open all exports, remove the burner. Prohibited immediately cold water into the furnace body should wait until the natural cooling. In order to avoid or reduce the casualties caused by the explosion of a gas boiler and its social, economic losses, we can adopt a more efficient boiler explosion-proof alarm system. For example, possible to detect the concentration of combustible gas leak sensors and alarms. Domestic and now have been developed using a gas sensor, a gas leak can be utilized, for measuring combustible concentration to alert the boiler furnace. The alarm high sensitivity, fast response time made of semiconductor material, the combustible gas sensor feel gas leak alarm immediately. Water spray system can be used as preventive measures early boiler fire and explosion. With the development of technology, artificial intelligence, and more high-tech will be applied to prevent an explosion in Henan gas boiler in the past.Free Chat
