Principle of micro oil ignition burner

     Micro oil ignition burner is mainly composed of micro oil ignition system, pulverized coal burner and control system composed of 3. The ignition system consists of micro oil combustion chamber and high voltage ignition gun, compressed air, oil burning systems, wall temperature monitoring, fire detection system. Pulverized coal burner mainly by the pulverized coal concentrator, a pulverized coal combustion chamber, a secondary combustion chamber, perimeter wind and wind cooling chamber. Control system on the ignition system and the powder feeding system control, programmed control ignition oil gun fire interlock protection, ensure the reliable operation of the boiler's safe and stable.
     Its working principle is: first use of compressed air jet fuel oil directly break, atomized into fine droplets of oil combustion, and skillfully using heat produced by burning the fuel is heated, expansion, so that the fuel in a very short time evaporation. The oil gun in the normal combustion process of direct combustion of oil and gas, thereby greatly improving the combustion efficiency and flame temperature. Gasification combustion flame rigid strong, fast spread, the flame was completely transparent (root is blue, middle and tail is white and transparent), flame center temperature of 1500 ~ 2000 photo C, as the temperature of the flame kernel in the pulverized coal burner for directly igniting pulverized coal combustion, thus using only a small amount of fuel to achieve power plant boiler starts, stops, and low load stable combustion.
     The compressed air is mainly used for fuel atomization and normal combustion to accelerate the fuel gasification and supplement the amount of oxygen required for the pre combustion, the high pressure air is mainly used for the oxygen content and the cooling oil combustion chamber. Classification and set fire to the secondary oil micro quantity gasified oil burning flame in pulverized coal burner formation temperature gradient is maximum local high temperature fire nuclear and put into a pulverized coal combustion chamber of dense phase pulverized coal by high temperature fire nuclear, coal particle temperature rapidly increased, broken up, and the release of a large number of volatile fast ignition and combustion, and then the ignition and combustion of dense phase pulverized coal in pulverized coal combustion chamber and dilute phase coal powder mixed dilute pulverized coal, pulverized coal combustion, the combustion energy gradually enlarged, reach the ignition and accelerate the combustion of pulverized coal, greatly reduce the coal powder combustion required ignition energy to meet the boiler start and stop and low load stable combustion of demand. The two film cooling wind is mainly used to protect the safety of combustion chamber, to prevent coking burning and post combustion required oxygen supplement.  http://www.bestfitburner.com
