　　EBICO EBS... series burner is the fourth generation of cpmpact 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.1tPBoiler Burner

　　The air/fuel linkage mechanism includes two servomotors, damper adjusting execution structure and gas flow regulating mechanism.The heat signal is needed to drive the air servo motor and the gas servo motor respectively at the same time.The fuel gas passes through the fuel gas flow adjustment mechanism, and the combustion air passes through the damper adjustment actuator to adjust the input amount of combustion air and fuel gas synchronously in proportion.1tPBoiler Burner

　　In order to ensure that there is an appropriate air/fuel ratio in all working conditions within the load regulation range, a motor is set on the damper and gas flow control valve to adjust the amount of combustion air and gas at each position, so as to achieve full combustion under the condition of low excess air coefficient.When the servo motor rotates, its output shaft directly drives the connecting rod to adjust the valve opening and gas flow valve opening respectively.In the process of debugging, according to the value of combustion supporting air and gas flow in the condition of small fire and big fire, the starting and ending positions of connecting rod linkage stroke are set.1tPBoiler Burner

　　Principle of flue gas recycling:1tPBoiler Burner

　　Some low-temperature flue gas is directly sent into the furnace, or mixed with air (primary or secondary air) into the furnace, because the flue gas absorbs heat and dilutes the oxygen concentration, so that the combustion speed and temperature in the furnace are reduced, because the thermal NOx is reduced.For gas boilers, NOx reduction is most significant.In general, thermal (t-no), rapid (p-no) and fuel (f-no) production pathways are available.The flue gas recycling system is connected with the gas burner. When the inert gas in the circulating flue gas enters the burner, on the one hand, the flame propagation speed will be reduced, and on the other hand, the temperature level in the furnace will be reduced due to the absorption of heat, so the absolute flame temperature will be lowered, which cannot reach the generation temperature. Therefore, the generation of t-no will be inhibited.Other components in circulating flue gas are N2,CO2and H2O in large quantities. As circulating flue gas is mixed in, oxygen concentration in the mixture of air and flue gas decreases, thus affecting the production amount.Mixing circulating flue gas in the air increases the content of N2in the reaction.Due to the high activation energy required for the reaction of oxygen and nitrogen atoms, a large amount of nitrogen failed to react with oxygen to form NO, and reacted with hydrocarbon components in the fuel.A large amount of N2increases the forward reaction of the above equation and generates a large amount of intermediate HCN.The oxygen atoms in the flue gas then react with these intermediate products. The total O2 reaction of HCN in the poor oxygen environment is as follows: HCN+ 5/4O2-+ 1/2N2+CO2+ 1/2H2O;According to the formula, under the condition of lean oxygen and dense combustion, HCN finally generates N2.Therefore, after adopting the flue gas recycling system, on the one hand, the intermediate product HCN increased, while on the other hand, the concentration of O2decreased compared with that before the flue gas recycling was not applicable, which promoted the complete reaction, and the amount of N2was greatly increased, thus reducing the generation of p-no.1tPBoiler Burner

　　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.1tPBoiler Burner

　　The development of hydrogen-rich tail gas burner is to reuse the hydrogen-rich tail gas discharged from air for a long time, thus improving the utilization rate of hydrogen-rich tail gas and saving production cost.At the same time, hydrogen-rich tail gas burner plays a positive role in promoting energy conservation and emission reduction, and will play a positive role in promoting the environmental protection and the technological progress, development and expansion of the burner industry, producing good social benefits.1tPBoiler Burner
