The working principle of the burner, the strength of the flame can be adjusted by the method of controlling the burner

To 　　 In addition, the total heat transfer coefficient of the burner is very important. The better the total heat transfer coefficient of the furnace tube, the more reasonable the furnace structure and the more heat transfer. The heating performance is related to the surface area of ​​the furnace tube. The larger the area of ​​the furnace tube where the flame is in contact with the flue gas, the more heat transfer; do you know that the heating capacity of the burner depends on the strength of the flame, the surface area of ​​the furnace tube and the total heat transfer The size of the coefficient. It doesn’t matter if you don’t know, now you know right away The 　　 combustion engine consists of an oil nozzle and an air regulator. The oil nozzle is arranged on the axis of the air regulator, atomizes the oil into fine droplets, sprays it into the combustion chamber at a certain diffusion angle (also called atomization angle), mixes with the air sent by the air regulator, and ignites. There are two main types of oil nozzles: pressure atomization and two-fluid atomization. The pressure atomized oil nozzle is composed of a splitter sheet, a swirling sheet and an atomizing sheet. The oil pressure is generally 2 to 3 MPa. The oil produces high-speed rotating motion in the swirl plate, sprays out through the center hole, and breaks into fine droplets under the action of centrifugal force. The average diameter of the oil droplets after the burner is atomized is below 100 microns. The two-fluid atomized oil nozzle uses steam or compressed air as the atomizing medium to accelerate the oil to break and atomize. The Y-type oil nozzle (Figure 3 Y-type oil nozzle) that uses steam as the atomizing medium is named because the steam channel and the oil channel form a Y-shaped oblique intersection. It has the advantages of large load adjustment range and low steam consumption. 　　 First of all, we should know the strength of the flame. The stronger the flame, the higher the furnace temperature, the greater the temperature difference between the furnace and the oil flow, and the greater the heat transfer. The strength of the flame can be adjusted by controlling the burner; 　　 In order to understand this knowledge, the knowledge that should be learned is that alcohol-based alcohol-based fuels mainly provide 10% hydrocarbons to crude methanol to increase the calorific value of the fuel. Since the addition of hydrocarbons may cause stratification during storage and use of alcohol-based fuels, appropriate addition of co-solvents enables alcohol-based fuels to be uniformly mixed with hydrocarbons without stratification. At present, this kind of fuel is used more, but the promotion of this kind of fuel control fuel formula is not more than 3 yuan fuel formula (without water), that is, methanol-cosolvent-hydrocarbon. It is not allowed to add harmful organic chemical products as additives, which complicates the formulation. At the same time, control the water content not to exceed 10%, and the hydrocarbon content should be compatible with cookware. 　　In actual use, poor flame combustion of the burner and coking of the furnace tube will affect the heating capacity of the burner. Therefore, attention should be paid to the control of the burner to make it burn completely, and to prevent local furnace tube temperature from being too high and coking.
