Description of drawings
Fig. 1 is the powdered coal burner head structural representation of high efficiency and low wear; Fig. 2 is a perspective view of the present utility model.
Among the figure, the big urceolus of 1-head, the big urceolus in 2-middle part, 3-head urceolus, 4-middle part urceolus, 5-head injector, 6-injector connector, 7-head discharge, 8-middle part discharge, 9-head cyclone, 10-cyclone connector.
The specific embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows: consult accompanying drawing 1 and Fig. 2.
1 one kinds of efficient coal burner heads that do not have wearing and tearing of embodiment are made up of the big urceolus of head, the big urceolus in middle part, head urceolus, middle part urceolus, head injector, injector connector, head discharge, middle part discharge, head cyclone, cyclone connector.It is characterized by the big urceolus of head, the big urceolus in middle part links by the mode of attachment bolt with the flange contact facings shimming; Head urceolus, middle part urceolus directly link by screw thread; Head injector, its end face 16 circular holes that circumferentially evenly distribute, and head injector and described injector connector directly link by screw thread; Head discharge, middle part discharge directly link by screw thread; The head cyclone is offered 24 eddy flow passages altogether, and head cyclone device and described cyclone device connector directly link by screw thread.
The operating procedure of present embodiment is as follows: 1. the coal burner head assembly of high efficiency and low wear is four air channel structure patterns, and the air channel is in proper order: (from outside to inside) cooling air, axial flow wind, coal wind, eddy flow wind.
2. by reasonable coupling design to axial flow air channel, coal air channel, three main channels, eddy flow air channel, can realize the negative pressure entrainment block that the coal burner head is bigger, so just can effectively entrainment the secondary wind of high temperature, guarantee the stable ignition burning of coal powder in kiln head, the outermost cooling air channel can effectively prevent the head wearing and tearing of burner and the flame of maintenance definite shape simultaneously, prevents the phenomenon of localized hyperthermia's scaling loss kliner coating.
