Will the heat transfer oil of the boiler diesel burner burn? What is the burning method?

Heat-conducting oil boiler diesel burner cyclone combustion: It is characterized by the fuel flow tangentially or axially into the cyclone tube, such as: fine coal, coarse powder. The high secondary wind direction cuts into the direction of the cyclone tube to generate a strong rotating airflow, which carries the fuel particles to rotate forward. Most of the large particles are thrown to the slag film on the cylinder wall and burned. A few subpided pipes are suspended and burned. The flue gas enters burnout-the cooling furnace is further burned out and cooled. The relative speed of fuel and air has increased greatly, intensifying combustion. The residence time in the drum is extended, and the boiler diesel combustion engine has high thermal efficiency. The cyclone tube is small in size and not resistant to cold, which is good for maintaining high temperature and saving steel. It has a wide range of applications and a high rate of cinder discharge. The liquid slag can be made into slag wool or other building materials. Its disadvantages are complex structure and manufacturing process, heavy burden of furnace lining maintenance, high pressure blower, fine fly ash and easy deposition. There are vertical and horizontal cyclone furnaces for gas boilers and diesel burners. The application range of cyclone combustion of gas boiler diesel burner is suitable for the comprehensive utilization of fuels such as calcium and magnesium phosphate fertilizer. Combustion of heat transfer oil: fuel spreads on the grate layer, air enters the grate gap through the fuel layer, most of the fuel burns to the grate, fine particles and combustible gases are separated from the fuel layer in the upper part of the fuel layer combustion space, the device It is a bed furnace, a layer burning furnace or a grate furnace. The system does not require pulverizing equipment, but it is limited by the size of the grate structure. Application range: Used for industrial boiler diesel burners and small power station boiler diesel burners whose capacity is less than or equal to 35t/h. Thermal oil boiler diesel combustion engine combustion: fuel powder (coal), mist (oil), gas (gas) is sprayed into the furnace cavity with air for suspension combustion, and the equipment enters the combustion chamber or suspension combustion furnace. The increase in the capacity of the thermal oil boiler diesel burner is not limited by the manufacture and layout of the combustion surface. The fuel has a large combustion reaction area and mixes well with air. A small excess air coefficient can be used, and the combustion efficiency is higher than that of fire bed combustion. However, because the fuel stays in the furnace for a short time, in order to ensure fuel combustion and combustion, it is necessary to equip a larger furnace area, and fuel regulation and operation management can easily be mechanized and automated. According to different fuel characteristics, there are pulverized coal stove, oil stove and gas stove. The pulverized coal furnace can be discharged by solid or liquid slag, and solid slag discharge is generally used in China. Liquid slag discharge is to maintain a sufficient high temperature in the lower part of the furnace, and the slag is completely melted. In the form of liquid slag, it is discharged from the lower part of the furnace and falls into the granulation tank through the slag well. In order to maintain the high temperature in the burner area, hot air is often used to feed powder and high hot air temperature, which is called furnace opening. In addition, a waist is formed in the lower part of the furnace body, and the furnace enters the slag chamber and cooling chamber to further increase the temperature of the slag chamber, which is called a half-open furnace. The furnace temperature decreases with the decrease of the load, and the excessively low flow rate makes the slag flow smoothly, which is called the critical load, which is usually 60% to 70% of the rated load. The discharge of liquid slag from the diesel burner of the heat-conducting oil boiler will cause high-temperature corrosion of the water wall, iron replacement in the slag pool, high NOx in the slag deposit and exhaust smoke, which need attention. Oil-fired gas furnaces with membrane water-cooled walls usually use micro-positive pressure combustion, which is suitable for low-oxygen combustion, which can reduce the SOx content in the flue gas, reduce low-temperature corrosion, and reduce air pollution. No induced draft fan is required, only a high-pressure head The blower requires strict sealing of the furnace cavity. The combustion of the diesel combustion engine room of gas boilers is mainly used in some industrial boiler diesel combustion engines. The burner area temperature of the liquid slagging furnace can reach 1600℃~1700℃, which is suitable for the ignition of low-ash melting coal and low-volatile coal. Boiling combustion of thermal oil boiler diesel burner: Air enters the furnace uniformly through the air distribution plate at an appropriate speed, and the coal particles are blown out and burn in the fire bed in a boiling state (fluidized bed), because the relative movement of the coal particles is strong. Staying on the boiling bed for a long time will greatly increase the combustion. The fluidized bed is usually equipped with a heating surface (buried pipe), after the ash flows out from the overflow. For low-quality fuels that cannot be burned in other combustion equipment (such as coal annihilation stones, stone coal, oil shale, etc.), stable fuels can be obtained in a boiling bed. At present, its scope of application is mainly used in the trial of industrial boiler diesel burners and small-capacity power station boiler diesel burners. After solving the problems of wear and efficiency, it is expected to be used in large-capacity boiler diesel burners. !
