Abstract
The utility model discloses a kind of oxygen coal burner to revolve device for coal, including oxygen hose and coal pipe, tube wall tangential direction of the coal pipe along oxygen hose are connected with oxygen hose, and the angle between the center line and plumb line of coal pipe is 15 degree.The utility model can extend the service life of oxygen coal burner outer shroud pulverized coal conveying, improve the jet velocity and coal blending degree of outer shroud pulverized coal conveying.
Description
Technical field
Coal gas field is the utility model is related to, particularly a kind of oxygen coal burner rotation device for coal.
Background technology
The coal dust rear end mode of movement of current domestic oxygen coal burner is mostly that single tube directly conveying or interior endless tube conveys, and outer shroud
The oxygen coal burner of pipe coal dust conveying is less, although existing outer shroud pulverized coal conveying can extend the service life of front end of burner, pipe
The wear problem in road does not solve well, and the front end combustion needs space of existing burner is big, and efficiency of combustion lifting is difficult.
The content of the invention
The purpose of this utility model is to provide a kind of oxygen coal burner rotation device for coal, can extend oxygen coal burner outer shroud and convey
The service life of coal dust, improve the jet velocity and coal blending degree of outer shroud pulverized coal conveying.
The purpose of this utility model is achieved in that a kind of oxygen coal burner rotation device for coal, including oxygen hose and coal dust
Pipe, tube wall tangential direction of the coal pipe along oxygen hose is connected with oxygen hose, between the center line and plumb line of coal pipe
Angle is 15 degree.
The present apparatus rationally increases the thickness at position easy to wear by the way that the eccentric tangentially band certain angle of coal dust is sent into coal dust endless tube
Degree and liner, can effectively mix coal dust, and oxygen coal front end of burner is delivered in the case where not reducing coal dust flow velocity, coal dust centrifugation spray
Project burner to burn with oxygen mix, improve combustion rate.The present apparatus can solve Ou Yelu well through making model measurement
Oxygen coal burner powder mixes difficult, pulverized coal channel quick abrasion and the slow-footed problem of breeze blowing, it is ensured that Ou Ye stove oxygen coal burners
Function and service life, hour can reach by theoretical calculation coal dust channel and lead to coal amount 54t/h, Theoretical combustion efficiency reaches
More than 98%.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is side structure schematic view of the present utility model.
Embodiment
