Abstract
The invention discloses a structure for preventing a burner nozzle of a gasification furnace from high temperature damages. The structure is characterized in that: a heated annular panel of the burner nozzle is provided with a plurality of minisize through holes, or the heated annular panel of the burner nozzle is made of a porous material capable of infiltrating liquid. So, cooling water can be ejected (exuded) out through micropores (or capillaries) of the heated annular panel and is quickly heated and vaporized, thereby consuming a great deal of heat radiated to the burner nozzle by the high temperature of the gasification furnace, and effectively maintaining the temperature of the heated panel of the burner nozzle at a lower level. The technical method of the invention can greatly promoting the cooling of the burner nozzle and can better solve the problem of damages of the burner nozzle of the gasification furnace caused by high temperature.
Description
Technical field
The invention belongs to the burner field, relate in particular to a kind of structure of avoiding gasification furnace to damage with burner noz(zle) high temperature.
Background technology
Coal gasifier is a device of fossil fuel (fine coal, oil, natural gas) being made coal gas, is widely used in fields such as chemical industry, nitrogenous fertilizer, combustion gas, cogeneration.In view of the oil-poor many matchmakers' of China resource situation, the vaporising fuel of China mainly is coal (fine coal or a water-coal-slurry).Burner noz(zle) (abbreviation burner) is the critical component of gasification furnace, also is the parts that the easiest high temperature damages.
More advanced coal gasification mode is the external large-scale powdered coal pressuring gasified technology of introducing at present.Utilize nitrogen or carbon dioxide that powdery carbon materials such as fine coal are sent into gasification furnace by burner, oxygen rich gas and water vapour are also sent into gasification furnace by burner simultaneously.Powdery carbon material and oxygen, steam reaction burning generate carbon monoxide and hydrogen, and ignition temperature reaches more than 1400 ℃.Because combustion flame temperature is very high, burner often causes damage because of high heat-flux and potential oxygen enrichment corrosive atmosphere.Cause the shutdown maintenance that large-scale gasification furnace is frequent because burner damages, cause manufacturing enterprise's enormous economic loss, caused the great attention of foreign technology provider and domestic relevant research institution, but up to the present do not dealt with problems effectively yet.As Chinese patent CN1015822B, CN1011617B, CN100470127C, CN200968601Y, CN1916493A, CN101250439A, CN101498441A etc., although these technology respectively have its characteristics, but its common thinking is exactly by changing cooling water runner, the attenuate burner panel etc. that is heated, so that promote the heat transfer between cooling water and burner panel, reduce the temperature of burner panel as far as possible and damage to avoid its high temperature.In fact, because gasifier temperature is very high, the heat flux that burner bears is very big, and the mode that relies on the cooling water sensible heat to carry heat fully is difficult to thoroughly deal with problems.
Summary of the invention
The objective of the invention is to damage at the easy high temperature of existing gasifier nozzle, particularly at the easy scaling loss of large-scale pressurization powder coal gasification furnace burner, the too short problem of life-span of external introduction, a kind of structure of avoiding gasification furnace to damage with burner high temperature is provided, so that improve the cooling effect of burner, avoid it damaged by high temperature, increase the service life.
Gasification furnace of the present invention is on the annular adjacent with cooling chamber (7) of burner is heated panel (6), to be placed with a plurality of micro through-holes (5) with the technical scheme of high temperature resistant burner; Or the annular adjacent with cooling chamber (7) of the burner panel (6) that is heated is made by porous material that can permeation liquid.
The pressure of cooling water is higher than the pressure in the gasification furnace in the cooling chamber (7).
On the annular adjacent with cooling chamber of burner is heated panel, be placed with some micro through-holes, or the annular adjacent with the cooling chamber panel that is heated is made by porous material that can permeation liquid.So, because the pressure of cooling water is higher than the pressure of gasification furnace in the cooling chamber, cooling water just sprays by the micro through-hole of panel, or ooze out by the capillary channel of its porous material, the vaporization of being heated of these ejections or the cooling water that oozes out, just consumed the heat of the high temperature of gasification furnace in a large number, can be effectively burner be heated the temperature maintenance of panel in lower level for the nozzle radiation.
In addition, one of coal gasification raw material is a steam, and present technique allows the cooling water of burner spray into the vaporization of (infiltration) gasification furnace, can not constitute influence to the operation of gasification furnace.
We know that the latent heat of vaporization of water is far longer than its sensible heat.Therefore, technology of the present invention is for reducing the be heated temperature of panel of burner effectively, and its effect is apodeictic.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
Among the figure: 1 central passage, 2 circular passages, 3,4-cooling water runner, 5 micro through-holes, the 6-annular panel that is heated, 7-cooling chamber.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
The high temperature resistant burner of a kind of gasification furnace provided by the invention is made up of central passage 1, circular passage 2, cooling water runner 3 and 4, is characterized in being placed with a plurality of micro through-holes 5 at the annular adjacent with cooling chamber 7 panel 6 that is heated; Or the annular adjacent with cooling chamber 7 panel 6 that is heated is made by porous material that can permeation liquid.
Present embodiment, cooling water pressure is 4.8Mpa, gasification furnace pressure is 3.8Mpa, cooling water just passes through the micro through-hole ejection of panel under both pressure differential effects, or ooze out by the capillary channel of its porous material, the vaporization of being heated of the cooling water of these ejections (oozing out) has just consumed the heat of the high temperature of gasification furnace for the nozzle radiation in a large number, makes burner be heated the temperature maintenance of panel in lower level.
Embodiment 1, and burner is the production technology burner.The be heated diameter of evenly arranging on the annular panel 6 of burner is the micropore of 0.1mm, and the density of arranging is 1 every square centimeter, each 1 of central passage and circular passage, be respectively coal dust-channel of nitrogen and oxygen-steam channel, the cooling water runner is two annular channels, and outer course enters, and interior road flows out.
The present invention can be used for the gasifier nozzle of various fuel, as coal gasification, and coal water slurry gasification, asphalt gasification, oil product gasification etc.Cooling water also can have only a runner, and promptly cooling water has only import, and outlet useless, the cooling of burner at this moment rely on fully from the cooling water gasification of annular panel ejection (oozing out) and finish.
