Abstract
The utility model discloses a novel nozzle tube panel device of supercritical cyclone burners. The novel nozzle tube panel device comprises a water cooling wall, wherein the water cooling wall is formed by tube bundles and adopts a membrane-wall spiral tube ring; burners are distributed at the middle part of the water cooling wall, adopt a front-rear opposed distribution mode and form a burner rotating port without containing refractory bricks; and a tube panel formed by the tube bundles and a spiral tube panel are integrally combined together. The novel nozzle tube panel device can be used for solving the problem of coking at the nozzle tube panel of the cyclone burners, structurally adapts to the novel nozzle tube panel of the supercritical cyclone burners without refractory bricks on the inner wall of cyclone burning, and avoids the coking generated when the coal powder washes out the high-temperature refractory bricks. The novel nozzle tube panel device also can be used for solving the following problems: the cyclone burning nozzle tube panel is bent out on the tube panel with a small inclined angle of a supercritical boiler; the distributing direction of the tube bundles is complex, and the safety and reliability of water circulation are guaranteed; the tube bending of the tube panel is irregular, the tube panel protrudes out, and the assembly with the burners needs to be considered; the requirement for the assembling accuracy of the burners is high; and the sealing requirement is high and the like. The novel nozzle tube panel device is applicable to the supercritical burner with cyclone burning. The novel nozzle tube panel is integrally assembled with the spiral tube panel, and is simple in site installation.
Description
Technical field:
the utility model relates to a kind of novel overcritical turbulent burner jet pipe screen device.
Background technology:
early stage supercritical unit of my company is for introducing technology, and its combustion system is the front-back wall opposed firing, and wherein turbulent burner spout tube panel is interior extension firebrick structure; Find that in actual motion phenomenon of coking appears in turbulent burner spout tube panel place; Be since when operation coal dust wash away highiy refractory brick, under action of high temperature, the thawing of coal dust imperfect combustion and lime-ash; Be bonded on the refractory brick, produce coking.
Summary of the invention:
The purpose of
the utility model provides a kind of problem that solves the place's coking of turbulent burner spout tube panel; The inwall that has adapted to swirl flow combustion on the structure does not have the novel overcritical turbulent burner spout tube panel of refractory brick, has avoided coal dust to wash away highiy refractory brick and the coking that produces.
Above-mentioned purpose realizes through following technical scheme:
a kind of water-cooling wall of restraining formation; Described water-cooling wall adopts the membrane wall spirally-wound tubes; Burner arrangement is at the middle part of described water-cooling wall; The form of the layout that liquidates before and after described burner adopts does not contain the refractory brick burner with pipe formation and revolves mouth, and tube panel that described tube bank forms and helical tube panel overall package are together.
described novel overcritical turbulent burner jet pipe screen device, described tube bank comprises the band steel that is welded on the pipe, described band steel connects another section band steel through round steel.
Beneficial effect:
1. the utility model have solved the problem of turbulent burner spout tube panel place's coking; The inwall that has adapted to swirl flow combustion on the structure does not have the novel overcritical turbulent burner spout tube panel of refractory brick, has avoided coal dust to wash away highiy refractory brick and the coking that produces.
2. the utility model have solved super critical boiler and on the very little tube panel in inclination angle, have bent swirl flow combustion spout tube panel; Tube bank is moved towards complicated and is guaranteed that safe water circulation is reliable; The tube panel bend pipe is irregular, and outstanding tube panel needs to consider and the burner assembling; High with burner assembling required precision; Problems such as seal request height are applicable to overcritical swirl flow combustion burner.This kind spout tube panel and helical tube panel overall package, the building site is installed simple.

The specific embodiment:
Embodiment 1:
a kind of novel overcritical turbulent burner jet pipe screen device; Its composition comprises: the water-cooling wall that tube bank forms; Described water-cooling wall adopts the membrane wall spirally-wound tubes; Burner arrangement is at the middle part of described water-cooling wall, and the form of the layout that liquidates before and after described burner adopts does not contain the refractory brick burner with pipe formation and revolves mouth, and tube panel that described tube bank forms and helical tube panel overall package are together.
promptly: described novel overcritical turbulent burner jet pipe screen device, and boiler water wall adopts the version of membrane wall spirally-wound tubes, and burner arrangement is the water-cooling wall middle part in front and back.
combustion system considers that emphatically the separate unit burner adopts the swirl flow combustion mode, and layout liquidates before and after many burners of whole boiler combustion system employing.
The pre-burning section of
burning is short, and spout tube panel protrusion height (about 460mm) is than the short about 50mm of original turbulent burner spout tube panel protrusion height (about 508mm).
single tube bending long radius forms circle.
spout tube panel forms burner with tube bank and revolves mouth, need not hang refractory brick.
this kind spout tube panel and helical tube panel overall package, the building site is installed simple.
Embodiment 2:
In
concrete structure; Tube bank 1, band steel 2; Described band steel connects another section band steel through round steel 3; Described band steel all is connected tube bank with described round steel, and one group is welded to form burner nozzle tube panel 4 by described tube bank and described band steel and described round steel, and described burner nozzle tube panel connects spiral panelized-tube-wall section 5.
