Abstract
The utility model relates to a fuel supplying device for an industrial combustion furnace, which is an efficient burner for refuse derived fuels. The efficient burner for the refuse derived fuels is provided with a central spray pipe and is characterized in that an air inlet pipe is sheathed outside the central spray pipe; a distance exists between the air inlet pipe and the central spray pipe to form an annular air inlet duct; a radial swirl air wing is arranged at the front between the two pipes to form a radial high-speed swirl air duct; a feeding pipe is sheathed outside the air inlet pipe; and the distance exists between the feeding pipe and the air inlet pipe so as to form an annular feeding channel. In the efficient burner for the refuse derived fuels, as combustible waste liquors, biomass fuel gases and the refuse derived fuels are sufficiently mixed to spray combustion by a high-speed whirlwind, the problems that the refuse derived fuels are hard to catch fire and are difficult to combust are solved; therefore, the efficient burner for the refuse derived fuels is mainly used for the fuel supply for the industrial combustion furnace.
Description
(1) technical field: the utility model relates to the fuel supply system of industrial combustion furnace, especially a kind of garbage derivatived fuel burner with high efficiency.
(2) background technology: the fuel nozzle that uses in the industrial combustion furnace mainly contains fuel oil, combustion gas class nozzle and powdered coal burner at present, fuel oil, combustion gas class nozzle mainly are to adopt straight tube shape nozzle simple in structure, powdered coal burner is then varied, and structure becomes increasingly complex.Growing tension along with the energy, people constantly seek various new energy materialses, to form derivatived fuel after the garbage disposal by extensive cognition, because the garbage derivatived fuel burning-point is higher, particle diameter is big, the difficulty of catching fire, burn, burn application in industrial combustion furnace, also do not find suitable burner, the utmost point is waited to develop.
(3) summary of the invention: the purpose of this utility model will solve higher, the difficulty of catching fire, burn of garbage derivatived fuel burning-point exactly, and the problem that ordinary burner can not be suitable for provides a kind of garbage derivatived fuel burner with high efficiency.
Concrete scheme of the present utility model is: the garbage derivatived fuel burner with high efficiency, has core jet pipe, outer cover at core jet pipe is equipped with blast pipe, between blast pipe and the core jet pipe spacing is arranged, form annular air inlet duct, and between two pipes, be positioned at the front portion and be provided with radial vortex wind wing, form the eddy flow air channel; Outer cover at blast pipe is equipped with feed pipe, has spacing to form annular feeding-passage between feed pipe and the blast pipe.
For making garbage derivatived fuel enter the favourable burning of diffusion rapidly in the stove, the port of export of feed channel described in the utility model is bell mouth shape.
For increasing the speed and the spin intensity of air intake, the outer wall of core jet pipe described in the utility model is horn-like, and the air inlet duct port of export is narrowed down, thereby can make the abundant mixing and burning of flammable waste liquid, air and derivatived fuel.
The utility model is simple in structure, design has the core jet pipe that sprays into for flammable waste liquid, biological fuel gas and the feed channel of air air inlet duct and garbage derivatived fuel (RDF), three passages, with the garbage derivatived fuel is main fuel, adopts flammable waste liquid or biological fuel gas igniting, combustion-supporting, is equipped with high speed whirlwind simultaneously, abundant mixing air fuel, thereby efficiently solve garbage derivatived fuel catch fire, burn the difficulty problem, firepower is big, sufficient combustion.
(4) description of drawings:
Fig. 1 is a main cutaway view of the present utility model.
Among the figure: 1-feed pipe, 2-feed channel, 3-blast pipe, 4-air inlet duct, 5-core jet pipe, 6-eddy flow wind wing.
(5) specific embodiment:
Referring to Fig. 1, the utlity model has core jet pipe 5, outer cover at core jet pipe 5 is equipped with blast pipe 3, between blast pipe 3 and the core jet pipe 5 spacing is arranged, form annular air inlet duct 4, and between two pipes 3 and 5, be positioned at the front portion and be provided with eddy flow wind wing 6 (being similar to helical fin), form eddy flow wind-guiding road; Outer cover at blast pipe 3 is equipped with feed pipe 1, has spacing to form annular feed channel 2 between feed pipe 1 and the blast pipe 3.
The port of export of the feed channel 2 described in the present embodiment (left end among Fig. 1) is bell mouth shape.
The outer wall of the core jet pipe 5 described in the present embodiment is horn-like, and air inlet duct 4 ports of export are narrowed down.
In order to improve service life, be convenient for changing, the core jet pipe in the utility model and the head of blast pipe adopt special the forming again with being responsible for dock thereafter of high-temperature steel to form, and see that the screw thread among Fig. 1 docks.
Claims (3)
1. the garbage derivatived fuel burner with high efficiency has core jet pipe, it is characterized in that: the outer cover at core jet pipe is equipped with blast pipe, between blast pipe and the core jet pipe spacing is arranged, form annular air inlet duct, and between two pipes, be positioned at the front portion and be provided with radial vortex wind wing, form the eddy flow air channel; Outer cover at blast pipe is equipped with feed pipe, has spacing to form annular feed channel between feed pipe and the blast pipe.
2. garbage derivatived fuel burner with high efficiency according to claim 1 is characterized in that: the port of export of described feed channel is bell mouth shape.
