Background technique
High velocity burner is mainly used in industrial furnace.General industry furnace is for heated material and guarantees fuel completely burned
All there is a spacious burner hearth.In this way, burner hearth, which is heated to operation temperature, when blow-on needs long time, and when blowing out,
Since thermal inertia still has greatly the quite a while to continue to heat workpiece, it is difficult to control heating temperature, workpiece is easily caused to overheat.For
Prevent workpiece from overheating, common heating furnace have to run under the maximum heating temperature that slightly above workpiece is allowed, this reduces
Heating speed increases heating time, especially even more so in the close heating final temperature of workpiece.
In addition, various adverse effects can be generated by extending heating time at high temperature, the oxidation and decarburization of steel are such as caused, work is made
The shortcomings that part surface is crude and hardness reduces, therefore in order to energy saving, eliminates common heating furnace, and with modern production flowing water
Line is mating, and rapid heating technology occurs in the 1960s.Quickly heating relies primarily on convective heat transfer rather than radiant heat transfer,
Its main feature is that furnace body is small, heating speed is fast, thermal inertia is small, heating workpiece quality is high, the thermal efficiency is high and is easy to automatically control.
The key quickly heated is realized first is that transformation furnace body;Second is that using high velocity burner.High quick burning in the prior art
There are two effects for burner, first is that combustion gas is made to burn under very high calorific intensity;Second is that making high-temperature flue gas with very high flow velocity
Combustion chamber is sprayed, to increase the effect of convective heat transfer in furnace.
And domestic high velocity burner flue gas emission speed in the prior art is high subsonic speed (200~300m/s), and energy
Surmount the application that rarely has that this speed reaches ultrasonic high velocity burner, and the present invention provides a kind of high-temperature flue gas to spray speed
Degree can reach the solution of supersonic speed (340m/s or more), higher heat exchange efficiency be provided than existing product, when shortening heating
Between, while flameless combustion is realized in the combustion chamber.
Summary of the invention
Goal of the invention: in view of the deficiency of the prior art, a kind of high velocity burner is provided.
Technical solution: in order to achieve the above-mentioned object of the invention, The technical solution adopted by the invention is as follows: a kind of high-velocity combustion
