A burner is a device for ejecting a mixture of fuel and air in a certain way.Burners are classified into industrial burners, burners, civil burners and special burners according to their types and application fields.Multi-purpose stainless steel or titanium metal corrosion resistant, high temperature resistant materials made.The role of the burner is to atomize the sample through flame combustion.The atomized test solution enters the burner and, under the action of flame temperature and atmosphere, goes through drying, melting, evaporation, dissociation and other processes to produce a large number of ground state atoms and some excited state atoms, ions and molecules.A well-designed burner should have the characteristics of high atomization efficiency, low noise and stable flame, so as to ensure high absorption sensitivity and precision of measurement.Gap burners are commonly used in atomic absorption spectrometry to generate atomic vapor.According to the different types of gas and auxiliary gas, the length and width of the gap of the burner are different. Generally, applicable gas and auxiliary gas are marked on the burner.
EBICO burner adheres to the three design concepts of "safety, environmental protection and energy saving", and combines the special design of the Chinese market environment and fuel.The product design scientific and reasonable, compact volume, perfect structure, low failure rate, high combustion efficiency, low energy consumption, high waterproof, dustproof, explosion-proof grade at the same time, the eu and China oil, gas road safety device load mandatory safety standards, electronic intelligent matching, operation, adjustment convenient, is the excellent products can fit with thermal equipment.
EBICO EBS… series burner is the fourth generation of compact type and electronic proportional control digital burner researched and development specially for asphalt mixing plant equipment. This burner is designed according to the three major ideas of European products on safety, environmental protection and saving energy, as well as special environment and fuel requirements of China market. It is a new generation of advanced intelligent electronic proportional control machine which is launched to the market after being approved by lots of test and qualified data. This model is scientific and rational in design, compact in size, complete in structure and low in failure rate. Through the application of many new technologies, it can save 5%-12% fuel and at most about 40% electrical energy; it is an ideal product suitable for both fixed asphalt mixing plant and mobile asphalt mixing plant.

From the perspective of heat transfer calculation, the measures to reduce the smoke exhaust temperature are analyzed from the following aspects: increasing the heat exchange surface, improving the heat exchange efficiency of the heating surface, improving the heat exchange temperature difference by using a lower temperature source, and reducing the influence of corrosion on the heat exchange efficiency.As gas boiler host first meet the low nitrogen flame furnace volume and size requirements, the second host of convection heating surface is a main export in order to reduce the smoke temperature, general control in 150 ~ 250 ° C, in order to avoid the smoke temperature increases along with the flue design difficulty of heat preservation, high smoking temperature is too low will cause corrosion in furnace convection heating surface forming wall condensation, therefore, furnace domestic demand to design proper heating surface, the physical dimension more representative chamber size.Increasing the heat exchange surface should mainly consider increasing the heat exchange area of the equipment in the rear of the boiler, which is more favorable for rapidly reducing the exhaust temperature.The second is to have a lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, corrosion resistant materials can be used to improve its service life.The new structure of efficient heat exchange mainly adopts the form of staggered tube arrangement, efficient heat exchange finned tube, plate heat exchanger, etc., to increase the flue gas disturbance and contact surface, reduce the heat resistance of flue gas stratification, and improve the heat exchange efficiency of medium and flue gas.
The insufficient capacity of the system to absorb clean energy is mainly reflected in the difference between the regulating capacity of the system and the actual demand for electricity load.In practice, the output of wind power, photovoltaic power and other new energy has a large fluctuation, and there is a big difference between the time period distribution and the electricity load. For example, wind power generally has a large output at night, but the electricity load is small at this time.Photovoltaic power output decreases rapidly in the evening, but the actual power load is approaching the evening peak.Hydropower output is affected by incoming water, flood season output is larger and dry period output is limited.In addition, considering the economy and safety, nuclear power generally undertakes the system basic charge and seldom participates in peak shaving.Under the comprehensive action of all the above factors, the actual dispatching and operation of the system is relatively difficult, and the adjustment ability becomes the key to determine the consumption level of clean energy.
