Laminar flow incinerator refers to the incinerator that burns materials or flames for laminar flow activities.
laminar flow
Laminar flow is an active state of fluid, which acts as a layer. When the fluid moves in the tube at low speed, it appears as laminar flow, and its particles move in a greasy straight line along the deviation parallel to the tube axis. The velocity of the fluid is very large in the middle of the tube and very small near the wall. The ratio of equilibrium velocity to very large velocity is 0.5.
Incinerator
The incinerator is a general assembly which makes fuel and atmosphere eject and burn in a certain way. According to the example and application platform, the incinerator can be divided into three types: Industrial incinerator, incinerator, civil incinerator and special incinerator.
In the broad view of incinerator, domestic water heaters, gas stoves, even lighters can be considered as a kind of incinerator. According to the principle of things, the incinerator can be defined as a kind of building which can transform materials into heat energy through the chemical feedback method of burning. It can mix the atmosphere and fuel through premixed installation in proper proportion to make them burn abundantly. Incinerators have many kinds of classification methods according to their different properties. According to the fuel method, it is divided into fuel oil incinerator, gas incinerator, light oil incinerator and dual fuel incinerator. In the detailed application, the fuel oil incinerator is divided into light oil incinerator, heavy oil incinerator, etc.; the gas incinerator is divided into natural gas incinerator, metropolitan gas incinerator, etc. According to the incineration mastering methods of the incinerator, they are: single stage fire incinerator, double stage fire incinerator and proportion adjustment incinerator. According to the fuel atomization method, they are: machine atomization incinerator and medium atomization incinerator; according to the layout, they are: integrated incinerator and split incinerator. This split type incinerator is mainly used in industrial manufacturing. Its main characteristics are: the incineration system, air supply system, control system, etc. are all explained and arranged. This kind of machine is mainly suitable for large buildings or high temperature and other external environment. Relatively speaking, due to the mass production of the incinerator with trade function and the low demand for professionalism in the environmental trend supply chain, the environmental trend selling cost of the product is relatively cheap, while due to the relatively high demand for professionalism of the split incinerator and numerous demands for professional placement forces, the environmental trend selling cost is relatively much higher than that of the previous year.
Laminar combustion is an important part in the study of combustion mechanism. With the increasing questions of power and environment, the demand of low fuel consumption rate and mastering the useless emission of internal combustion engine is higher and higher; therefore, it is very urgent to strengthen the study of combustion mechanism. In the real spark combustion engine, the flame is initially laminar flame. With the development of flame, the laminar flame changes into turbulent flame. But at this time, the development layout of turbulent flame is highly folded laminar flame. Under the similar turbulence intensity and intake method, the turbulent combustion rate depends on the chemical properties of different fuels, that is, the laminar combustion of fuel Features. Therefore, laminar flame is the base of turbulent flame, the tension component that affects the combustion state and compliance of internal combustion engine fuel, and the tension basis for the surface to look forward to the combustion process and to study the manufacturing mechanism of emissions. In addition, the laminar burning rate or the tight parameter used to verify the chemical feedback mechanism of fuel is also one of the tight input parameters to simulate the propagation of turbulent premixed flame. Therefore, the research on the characteristics of fuel laminar combustion has a more intense role. In the past 50 years, with the continuous progress of trial technology, researchers in various countries pay great attention to the trial construction, trial technology and the improvement and application of new technology while conducting the laminar combustion research. For this reason, the paper describes the experimental techniques of laminar combustion which are often used in the world, including Bunsen burner method, plane incinerator method, stagnant surface method and constant volume combustion bomb method, explains the experimental principle and layout, illustrates the advantages and disadvantages of various techniques, and provides a reference for the better development of experimental research of laminar combustion
The ignition method of diesel engine with uneven gas inclusion is caused by carbon smoke. Because the process of manufacturing and oxidation of carbon smoke is very complicated, so it is still not very well understood and decomposed. The study on the cause and correlation of soot depends largely on the timely observation of soot and other components in the flame. More and more attention has been paid to the measurement of flame carbon diffusion without disturbing the combustion environment. Based on the LII signal at one point in the flame obtained at two wavelengths, the temperature of the soot particles heated by laser is obtained, and the soot concentration at this point is obtained, and the two-dimensional soot concentration of the flame is obtained through reflection The two-dimensional diffusion of carbon smoke precursor polycyclic aromatic hydrocarbons in the flame can be obtained by adopting laser induced fluorescence. The laser induced fluorescence and laser induced incandescence are connected, and the experiment is carried out in the laminar dispersion flame of diesel and biodiesel mixed with fuel for a long time. The consequence of the study is explained that with the increase of the blending proportion of biodiesel, the very large concentrations of carbon smoke and polycyclic aromatic hydrocarbons will fall, and the concentration will be high The area of the discriminating cloth also shrinks further
Pulverized coal incinerator is a link building in the boiler incineration system, its function plays an important role in the reliability and economy of the incineration building. On the other hand, the fuel type NOx, which accounts for a large part of NOx, is manufactured in the initial stage of ignition and incineration of pulverized coal, and has gone through a specially planned incinerator layout
