Horozontal oil fired steam boiler
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.
Boiler plant in Henan What are the advantages of industrial boiler manufacturing industry in the middle of our country is a very wide range of common industrial equipment. The main boiler is a thermal energy supply device consists of two main parts consisting of pots and oven, and is widely used in many areas of residential heating and chemical. Market now above the boilers are more buyers prefer purchasing goods and services in the middle of a good boiler plant in Henan Province, the Henan Boiler Plant these particular what are the advantages? First, with advanced production equipment and complete production equipment, excellent evaluation test or not is a manufacturer of industrial importance. Henan boiler plant with more advanced production equipment to ensure that the products produced have relatively high quality. It also has a high level of operating welding equipment and advanced computer-aided design and a series of related equipment. Second, have a varied product has a very long history of manufacturing the type of boiler boiler plant in Henan, Shandong gas boiler is very comprehensive. Henan Boiler Plant is capable of producing good quality hot water boilers and various gas boiler in line with national environmental standards. Also different types of horozontal fired steam boilers, oil-fired boiler and boiler oil boiler and many other products are also included. Third, the product has a unique feature of good service Shandong gas boiler has determined the need for customers to buy after a series of work before they can be put into use after including the safe transportation of goods and the correct installation and commissioning, and many other work. And a very good market reputation boiler plant in Henan Province has a very good quality and after-sales service attitude. Overall boiler plant in Henan Province has been able to win the widely popular among consumers in the market, depending on the characteristics of the advantages detailed above in Henan Boiler Plant owned by these three aspects. That is, complete with advanced production equipment, we can produce various kinds of products as well as different types of boiler can provide good after-sales service.
The oil gas power plant boiler has low NOx emissions in the flue gases. In the combustion zone of the boiler, the membrane wall is spiral wound, utilizing smooth-bore tubing. This inclined-tube arrangement reduces the number of parallel paths compared with a vertical-wall arrangement and therefore increases the mass flow of steam/water mixture through each smooth-bore tube. The development and realization of high efficiency methods for burning the oil and gas fuel in our power plant boilers make it possible to save fuel and reduce the emission of harmful substances while meeting rigorous safety requirements.
