Abstract
The present invention relates to a kind of startup burner igniter nitrogen protection device; there is a sleeve being sleeved on startup burner central passage rear portion and one be inserted into the spark lever in startup burner central passage by sleeve rear end; the sidewall of sleeve has the nitrogen inlet passing into startup burner central passage, spark lever rear link wall has nitrogen inlet.In real work, before startup burner runs, pass into protection nitrogen by sleeve nitrogen inlet in spark lever, protection nitrogen divides two-way to lead to the ejection of spark lever head.When startup burner runs; spark lever head completely by nitrogen around; this makes it possible to effectively protect spark lever head; prevent the impact of high temperature gas flow radiation; and when the flame-out stage; because nitrogen pressure in spark lever is higher than ambient exterior atmospheric pressure, therefore, it is possible to effectively prevent the tempering of spark lever head, ensure spark lever security of operation.Product has advantage rational in infrastructure, easy to operate, effectively can to improve spark lever service life.
Description
Technical field
Content of the present invention belongs to coal gasification apparatus technical field, relates to a kind of startup burner igniter nitrogen protection device.
Background technology
To go into operation the nucleus equipment of device as igniting, integrated startup burner mainly plays a part as dry powder pressing gas gasifying device increasing temperature and pressure.Before gasification installation is driven, startup burner controls to be pushed into the desired location that mechanism pushes burner hearth inside with regard to cabinet by middle control DCS or scene, after igniting driving order is assigned, each pipeline of burner starts to fill inert gas (nitrogen) and purges, delayed filling fuel and oxidant, when participating in the fluid of burning while head builds pressure ejection, high energy electricity ignition device is started working, and is lighted by startup burner.When furnace pressure temperature is raised to scope of design, main process burner comes into operation successively, and after two process burners normally work, startup burner extinguishes, and propulsive mechanism is extracted burner out burner hearth and retreated to safety zone, and so far startup burner completes driving igniting task.
Integration startup burner is all utilize the igniter carried to light a fire, its high energy electricity ignition device is positioned at startup burner head center position, when the electric arc relying on igniter to produce after oil, oxygen ejection burner is lighted a fire, original igniting and startup burner are united two into one, therefore the stability of igniter and durability just seem most important.The structure of current integrated startup burner well known in the art as shown in Figure 1, the main sparking element ignition bar 1 of high-energy igniter is arranged on the centre of startup burner 4, its Problems existing is: the localized tempering of the hyperthermia radiation in the startup burner course of work and SUB turn-off transient is on the impact of spark lever head comparatively large (easily causing igniter head scaling loss), and the moment threatens the safety of igniter; That encapsulant (as epoxy resin etc.) is set at the head of spark lever for solution to the problems described above, but the easy carbonization of encapsulant in the past, thus the method fail the real safety effectively ensureing spark lever head.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, a kind of rational in infrastructure, easy to operate, startup burner igniter nitrogen protection device that effectively can improve spark lever service life is provided.
Designer of the present invention is found by experimental observation; no matter prior art is the threat that the localized tempering of SUB turn-off transient or hyperthermia radiation produce spark lever; all because have ignored the cooling protection to spark lever; therefore while startup burner comes into operation in a large number; if the protective gas of a road higher than furnace pressure can be introduced; just can cut off tempering and hyperthermia radiation to the heat affecting of spark lever, thus improve the service life of spark lever.The technical solution that the present invention makes accordingly is such: the startup burner igniter nitrogen protection device provided there is a sleeve being sleeved on startup burner central passage rear portion and one be inserted into the spark lever in startup burner central passage by sleeve rear end; the sidewall of sleeve has the nitrogen inlet passing into startup burner central passage, spark lever rear link wall has nitrogen inlet.
Technical solution of the present invention also comprises: the afterbody of described spark lever adopts threaded engagement washer sealing to be connected with the rear portion of described sleeve.
In practical work process; in spark lever, protection nitrogen is passed into by the nitrogen inlet that sleeve lateral wall is opened before startup burner runs; protection nitrogen divides two-way to lead to the head of spark lever and startup burner; the annular space that one curb spark lever outer wall and startup burner central passage inwall leads to head; the entrance access points picker bar of spark lever outer wall of separately leading up to is inner, is then sprayed by spark lever head.After spark lever structure and installation form being improved by design of the present invention; when startup burner runs; spark lever head completely by nitrogen around; this makes it possible to effectively protect spark lever head; prevent the impact of high temperature gas flow radiation, and when the flame-out stage, because nitrogen pressure in spark lever is higher than ambient exterior atmospheric pressure; therefore, it is possible to effectively prevent the tempering of spark lever head, ensure spark lever security of operation.
Compared with prior art, of the present invention rational in infrastructure, easy to operate, result of use is good.Due to the addition of for spark lever one tunnel protection nitrogen, make startup burner in the course of the work spark lever head have nitrogen protection all the time, play cooling and isolation high temperature gas flow effect; Arrange because this novel point picker bar have employed nitrogen envelope again, therefore head is without the need to adding any encapsulant again, prevents the danger of encapsulant carbonization, effectively can ensure the safety of spark lever head; Stop working the stage at startup burner, the high pressure nitrogen of spark lever inside blowout effectively can prevent spark lever head scaling loss, resists the threat that flame presses close to spark lever head.Effectively improve the service life of spark lever by the enforcement of above-mentioned technical solution, the practicality of startup burner and economy are greatly improved.

In figure, the title of each number designation respectively: 1-spark lever, 2-sleeve, 3-nitrogen inlet, 4-startup burner, 5-first strand of nitrogen, 6-second strand of nitrogen, 7-nitrogen inlet, 8-sealed copper packing ring.
Detailed description of the invention
Below with reference to accompanying drawing, content of the present invention is described further, but practical application structure of the present invention is not limited in following embodiment.
See accompanying drawing; startup burner igniter nitrogen protection device of the present invention comprises and is fitted in sleeve 2 on startup burner 4 and spark lever 1; sleeve 2 is sleeved on startup burner 4 central passage rear portion; spark lever 1 is pushed by startup burner 4 afterbody through sleeve 2; burner head is reached by the central passage of startup burner 4; the afterbody of spark lever 1 adopts thread seal to be connected with the rear portion of sleeve 2; the sidewall of sleeve 2 has the nitrogen inlet 3 passing into startup burner 4 central passage, the rear link wall of spark lever 1 has nitrogen inlet 7.In real work; in spark lever, protection nitrogen is passed into by the nitrogen inlet 3 of sleeve 2 before startup burner runs; protection nitrogen divides two strands of heads leading to spark lever and startup burner; first strand of nitrogen 5 leads to head along the annular space of spark lever outer wall and startup burner central passage inwall; second strand of nitrogen 6 is inner by the entrance access points picker bar of spark lever outer wall, then is sprayed by spark lever head.
