Burners are more and more common in people's lives

　　Burners are more and more common in people's lives, closely related to our lives, the following is to introduce the structure of the burner so that we can better understand the burner.iFaBoiler Burner

　　1. Fuel systemiFaBoiler Burner

　　The function of the fuel system is to ensure that the burner burns the required fuel.The fuel system of fuel burner mainly includes: oil pipe and joint, oil pump, solenoid valve, nozzle, heavy oil preheater.Gas burner has a filter, regulator, solenoid valve set, burning solenoid valve set, fuel butterfly valve.iFaBoiler Burner

　　2. Combustion systemiFaBoiler Burner

　　The function of the combustion system lies in the mixture of ignition air and fuel, and its primary components are: combustion transformer, combustion electrode, high voltage electric fire cable.iFaBoiler Burner

　　3. Monitoring systemiFaBoiler Burner

　　The function of the monitoring system is to ensure the safe and stable operation of the burner.iFaBoiler Burner

　　4. Air supply systemiFaBoiler Burner

　　As a kind of mechanical and electrical integration equipment with a higher degree of automation, the burner can be divided into five systems according to its completed functions: air supply system, combustion system, monitoring system, fuel system and electronic control system.iFaBoiler Burner

　　The function of the air supply system is to send certain wind speed and air volume into the combustion chamber, the main components are: shell, fan motor, fan impeller, air gun, damper controller, damper baffle, CAM conditioning mechanism, and loose disk.iFaBoiler Burner

　　5. Electronic control systemiFaBoiler Burner

　　Electronic control system is the command base and contact base of the above systems, the primary control element is program controller, for different burners with different program controller, common program controller has: LFL series, LAL series, LOA series, LGB series, its primary difference is the time of each program process is not the same.iFaBoiler Burner

　　Burners can be divided into coal burner, oil burner and gas burner.iFaBoiler Burner

　　There are two kinds of pulverized coal burner, i. e.iFaBoiler Burner

　　(1) swirling pulverized coal burner: the primary air cyclone, secondary air conditioning baffle (cyclone blade or volute) and a secondary air nozzle.It can be placed on the front wall, two walls or front and rear walls of the combustion chamber.The air conveying pulverized coal is called primary wind, which accounts for about 15 ~ 30% of the total air volume required for combustion.A mixture of pulverized coal air is injected into the combustion chamber through a primary air nozzle of the burner.The other air needed for combustion is called secondary air.The secondary air passes through the adjusting baffle of the burner (cyclone blade or volute) and forms the rotating air flow, which forms a rotating jet at the outlet of the burner and the primary air sink.The negative pressure formed by the jet base sucks the high-temperature smoke into the flame root.This high temperature flue gas is the primary source of coal ignition.The diffuser cone at the primary air outlet can increase the slack Angle of primary air to enhance the entrainment effect of high temperature flue gas.iFaBoiler Burner

　　(2) direct flow pulverized coal burner: usually placed along the height of a number of groups, secondary air nozzle composition, arranged in each corner of the combustion chamber.The base line of the burner is tangent to an imaginary circle at the center of the combustion chamber, thus forming a horizontally rotating updraft in the combustion chamber.The first and second air nozzles of each group of direct flow burner are loosely arranged to meet the demand of stable and thorough combustion of different coal types.iFaBoiler Burner
