Abstract
The invention relates to a fuel supply device of an industrial combustion furnace and provides an efficient combustor for waste derived fuel. The efficient combustor comprises a central spraying pipe and is characterized in that an air inlet pipe is sleeved outside the central spraying part; a gap is arranged between the air inlet pipe and the central spraying pipe to form an annular air inlet path, and a radial whirl air fin is arranged at the front part of the space between the air inlet pipe and the central spraying pipe to form a radial high-speed whirl air path; a charging pipe is sleeved outside the air inlet pipe; and a gap is arranged between the charging pipe and the air inlet pipe to form an annular charging path. In the invention, combustible waste liquid, biomass fuel gas and the waste derived fuel are mixed completely through high-speed whirlwind for spraying combustion, so that difficulties in firing and combusting the waste derived fuel are solved; and the efficient combustor is mainly used for the fuel supply of the industrial combustion furnace.
Description
(1) technical field: the present invention 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: purpose of the present invention 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 invention 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 present invention is bell mouth shape.
For increasing the speed and the spin intensity of air intake, the outer wall of core jet pipe of the present invention 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 present invention 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 invention.
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 present invention has core jet pipe 5, in the outer cover of core jet pipe 5 blast pipe 3 is housed, between blast pipe 3 and the core jet pipe 5 spacing is arranged, form annular air inlet duct 4, and be positioned at the front portion at two pipes between 3 and 5 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 among the present invention 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.
