Abstract
The invention relates to a startup burner igniter nitrogen protecting device which is provided with a sleeve and an ignition rod. The sleeve is arranged on the back portion of a startup burner center channel in a sleeved mode. The ignition rod is inserted into the startup burner center channel from the back end of the sleeve. A nitrogen inlet which is communicated with the startup burner center channel is formed in the side wall of the sleeve. A nitrogen entering opening is formed in the rod wall on the back portion of the ignition rod. In practical working, before startup burner operation, protecting nitrogen enters the ignition rod through the sleeve nitrogen inlet, and the protecting nitrogen is sprayed out through the head of the ignition rod in two ways. During startup burner operation, the head of the ignition rod is completely surrounded by nitrogen so that the head of the ignition rod can be effectively protected, and the influence from high-temperature airflow radiation is avoided. At a flameout stage, nitrogen pressure in the ignition rod is higher than external environment pressure, tempering of the head of the ignition rod can be effectively avoided, and safe operation of the ignition rod can be guaranteed. The startup burner igniter nitrogen protecting device has the advantages of being reasonable in structure and convenient to operate, and the service life of the ignition rod can be effectively prolonged.
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
As the go into operation nucleus equipment of device of 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 is controlled and is 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 the fluid that participates in burning is when head is built pressure ejection, high energy electricity ignition device is started working, and startup burner is lighted.When furnace pressure temperature is raised to scope of design, main process burner comes into operation successively, and after the normal work of two process burners, 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.
Integrated startup burner is all to utilize the igniter carrying to light a fire, its high energy electricity ignition device is positioned at startup burner head center position, the electric arc that relies on igniter to produce after oil, oxygen ejection burner is lighted a fire, original igniting and startup burner are united two into one, so the stability of igniter and durability just seem most important.The structure of integrated startup burner well known in the art as shown in Figure 1 at present, the main sparking element spark lever 1 of high-energy igniter is arranged on the centre of startup burner 4, the problem of its existence is: the localized tempering of the hyperthermia radiation in the startup burner course of work and SUB turn-off transient affects large (easily causing igniter head scaling loss), the safety that is constantly threatening igniter to spark lever head; For solution to the problems described above, be that head at spark lever arranges encapsulant (as epoxy resin etc.), but the easy carbonization of encapsulant in the past, thereby the method fail really effectively to ensure the safety of spark lever head.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, provide a kind of rational in infrastructure, easy to operate, can effectively improve the spark lever startup burner igniter nitrogen protection device in service life.
Designer of the present invention finds by experimental observation; no matter prior art is the localized tempering of SUB turn-off transient or the threat that hyperthermia radiation produces spark lever; all because ignored the cooling protection to spark lever; therefore when startup burner comes into operation in a large number; if can introduce a road higher than the protective gas of furnace pressure; just can cut off the heat affecting to spark lever of tempering and hyperthermia radiation, thereby improve the service life of spark lever.The technical solution that the present invention makes is accordingly such: the startup burner igniter nitrogen protection device providing has a sleeve that is sleeved on startup burner central passage rear portion and one and is inserted into the spark lever in startup burner central passage by sleeve rear end; on the sidewall of sleeve, have the nitrogen inlet that passes into startup burner central passage, on spark lever rear link wall, have 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; the nitrogen inlet of opening on by sleeve lateral wall before startup burner operation passes into protection nitrogen in spark lever; 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 inlet point picker bar of spark lever outer wall of separately leading up to is inner, then by spark lever head, is sprayed.After spark lever structure and installation form being improved by design of the present invention; when startup burner moves; spark lever head completely by nitrogen around; so just can 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 external environment condition pressure; therefore can 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.Owing to being that spark lever adds Liao Yi road protection nitrogen, make startup burner in the course of the work spark lever head have all the time nitrogen protection, play effect cooling and isolation high temperature gas flow; Because this novel point picker bar has adopted nitrogen envelope, arrange again, so head is without adding any encapsulant again, has prevented the danger of encapsulant carbonization, can effectively ensure the safety of spark lever head; In the flame-out stage of startup burner, the high pressure nitrogen that spark lever inside blows out can effectively prevent spark lever head scaling loss, resists the threat that flame is pressed close to spark lever head.By the enforcement of above-mentioned technical solution, effectively improved the service life of spark lever, the practicality of startup burner and economy are greatly improved.
