Abstract

The utility model discloses a coal dust concentrating sleeve used for a burner, which comprises a coal dust concentrating sleeve. A wedge coal dust concentrating block is arranged at the coal dust airflow inlet end of the inner wall of the concentrating sleeve and can be arranged as an integral ring of wedge block or divided into small wedge blocks according to one-two rings, and each ring of wedge blocks are staggered mutually, thus leading the coal dust to be effectively concentrated in a central cylinder; coal dust airflow with concentrated center part and weak periphery is formed in the concentrating sleeve, thus leading the coal dust at center part to catch fire for burning quickly; and simultaneously, the weak coal dust air flow at the periphery plays the role of cooling the outer wall of the concentrated sleeve. A thermoelectric couple is arranged on the concentrating sleeve and used for monitoring the temperature of the cylinder wall, thus preventing the sleeve from being coked or damaged due to overtemperature; and the outlet side of the coal dust airflow on the sleeve is provided with an expansion groove, thus preventing the sleeve from deforming and cracking due to expansion by heating.

Description

A kind of burner Pulverized Coal Concentration sleeve
Technical field:
The utility model relates to a kind of plasma burner, particularly relates to a kind of burner Pulverized Coal Concentration sleeve.
Background technology:
Rise along with the in short supply and price of the energy, current, countries in the world are all at the energy strategy of implementing energy-saving and emission-reduction, and conduct realizes being subjected to increasing attention and popularization at home by the plasma non-oil ignition technological system of one of important technology that station boiler is energy-conservation.Yet application Plasma Firing Technology; the Pulverized Coal Concentration structure of burner inside is one of key link; how to adopt rational structure and material; can effectively prevent the wearing and tearing of coal dust; can implement to concentrate to coal dust preferably again; it is caught fire fast at the burner center light, can also protect burner inner wall not have coking and the generation of scaling loss situation simultaneously, become the fast-developing from now on key of this technology.
Summary of the invention:
The purpose of this utility model is to provide a kind of Pulverized Coal Concentration sleeve arrangement that is applied to plasma pulverized coal ignition burner; the utility model is rational in infrastructure; adopt the cast steel material of antiwear heat resisting to make, can protect burner inner wall not have coking and the generation of scaling loss situation effectively.
Technical solution of the present utility model is: a kind of burner Pulverized Coal Concentration sleeve, be by concentrated sleeve, inner core, the Pulverized Coal Concentration piece, temperature measuring equipment is formed, it is characterized in that: described inner core is arranged on and concentrates in the sleeve, front end breeze airflow entrance point at inner core is furnished with some wedge Pulverized Coal Concentration pieces, the Pulverized Coal Concentration piece, the wedge type block that can be arranged as whole circle or cut apart by the 1-2 circle, each encloses wedge type block and staggers each other, be provided with expansion slot at the inner core breeze airflow port of export, be provided with gusset between inner core and the concentrated sleeve, it is interconnected, and described concentrated sleeve is provided with temperature measuring equipment.The utility model is simple in structure, and is easy for installation, can protect burner inner wall not have coking and burning phenomenon generation effectively.
Description of drawings: Fig. 1 is the utility model structural representation
1. concentrate the sleeve 2. Pulverized Coal Concentration pieces 3. breeze airflow entrance points 4. breeze airflow ports of export 5. expansion slots 6. inner cores 7. temperature measuring equipments
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, a kind of burner of the utility model Pulverized Coal Concentration sleeve is made up of concentrated sleeve, inner core, Pulverized Coal Concentration piece, temperature measuring equipment.During concrete enforcement, the Pulverized Coal Concentration sleeve is arranged near the defeated arc pipe outlet side of plasma.Be furnished with wedge Pulverized Coal Concentration piece at concentrated sleeve lining breeze airflow entrance point, can be arranged as whole circle or be divided into little wedge type block by the 1-2 circle, each encloses wedge type block and staggers each other, it is effectively concentrated that coal dust is carried out in central tube, the dense light breeze airflow all around in formation center in concentrating tube, the center coal dust of making can be quick fire burns, simultaneously the light coal dust air draught of periphery plays the effect of cooling concentration sleeve outer wall.Be furnished with 4-6 gusset at sleeve outer wall and be used for sleeve fixing in burner, have the tilted conical non through hole on one of them gusset, nose end gos deep into the sleeve wall, be used to install thermocouple monitoring barrel temperature, prevent coking of sleeve overtemperature or scaling loss, open 4-8 expansion slot at wind outlet side of sleeve, prevent that the sleeve expanded by heating from producing distortion and cracking.
