Energy Saving Fully Automatic Industrial Oil Steam Boiler for Heating
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.
Gas energy saving fully automatic industrial steam boiler for heating not only focus on their own function and more environmentally friendly gas-steam oven due to heat and heat transfer equipment, and for many professions. Screening of its upgrade and shopping centers is very high, and even some of the new products will be screened in a few years. If we can not meet these requirements, this highly competitive industry on the development of the oil furnace put forward new requirements. If you do, you will certainly face a screening room. Today's gas-steam oven not only focus on their own function, but also more environmentally friendly. As long as the bow is in line with today's society about the development of high-tech products, otherwise it will be empty talk. Insulation gas steam oven is a very important factor to measure the value of its shopping centers. Steam oven gas having good insulation function expensive than about 20% of oil furnace insulation function difference. Do not underestimate the 20% of the costs and profits. A very scary figure. Gas insulated steam oven is mainly reflected in its interior. Some oil furnace with a heat insulation material, which is integrated with the oil furnace. They do not conflict with other raw materials. Let's talk about this oil furnace. The product is called high-tech insulation oil furnace products. Because it is equipped with a high-quality insulation material, and therefore require a longer heating temperature and longer data to assist the burning material processing company. The purpose is to save money for the company. At present, commonly used as a furnace gas and steam insulation materials include products of rock wool insulation panels, foam insulation board cement, Portland composite panels and aluminum panels. We expect a wide range of gas-steam oven manufacturers will focus on the selection of the insulating material. Them into account, because they are really suitable for insulating oil furnace.

Steam boiler furnace operating point first launched circulating pump equipment circulating pump outlet, into the furnace, the pressure released, and the system back to the oil pressure, make sure that in the positive practice mode. Circulation pump run for 30 minutes, after the stable operation of the system before it can enter the next step. Open gas pipeline manual valve energy saving fully automatic industrial steam boiler for heating, burner launch button, natural gas burner into the furnace, and then burned, keeping the flame stable condition, is in the safe operation of the equipment. Incineration steam boiler, once the accident shut down if the phenomenon occurs, the device will take the initiative burner interlock protection status, should be promptly cut off natural gas pipeline, launched a purge function of the furnace, the furnace inside air replaced more than clean shutdown. System according to load requirements, temperature requirements and thermal oil outlet, the burner can be actively adjust the size of the amount of fire. Steam boiler heat exchanger is generally divided into two, one is directly touch the touch exchanger, and the other is the direct heat exchanger, which are separate apparatus for flue gas waste heat recovery, energy saving effect complete . Generally steam boiler practices can be simple progress through the transformation of energy-saving action, such as increasing the waste heat recovery equipment installed on, which is energy-saving advantages of steam boilers. Energy savings from the big side, is to promote the cause of saving the country, to say that small ways to create more profits for the company to save costs, the choice of one of the heat exchanger is a good way to complete energy policy.
