Abstract
The utility model relates to a circulating reburning apparatus of a boiler, which is composed of an ash outlet, a circulating pipe, a blower, a recovery nozzle, etc. The utility model is characterized in that the front part of the recover nozzle is conical, and is extended in a boiler furnace, the back upper part of the recover nozzle is connected with one end of the circulating pipe, the tail of the recover nozzle is connected with the blower, and the other end of the circulation pipe is welded on a funnel-shaped outlet of ash outlet; the boiler ash goes into the circulating pipe from the ash outlet, and returns the recovery nozzle, and the ash is jetted back to the boiler furnace for burning by the blower in high-speed jet. Thus, the burning rate of bagasse raises 30 percents, the black smoke of a chimney is obviously reduced, and large granular combustible matters in the ash reduce 90 percents. The output of the boiler is raised, the service life of the apparatus is prolonged, and the favorable environmental protecting effect is received.
Description
The utility model belongs to a kind of boiler burner again that circulates.
At present, the production boiler in sugar refinery is that fuel drives the production of whole press for extracting juice season with byproduct one bagasse.The combustion efficiency of bagasse directly influences exerting oneself of boiler and presses season and produce.It is insufficient when burning that present ubiquity bagasse, cause that boiler thermal output is low, fuel consumption is big, lime-ash is many, serious environment pollution, a large amount of unburnt combustibles are deposited on boiler tail, easy blocking pipe, the accident that causes equipment such as air preheater, steelframe to burn out.Patent 93209175.X bagasse boiler boiling combustion device though can improve efficiency of combustion, prolongs fire grate service life, still has lime-ash to discharge, and is not ideal enough.
The purpose of this utility model provides a kind of boiler burner again that circulates, and makes full use of the lime-ash burning again that circulates, and has not only improved the thermal efficiency, has reduced pollution, and has reduced the deposition of lime-ash, avoids burning out the generation of equipment breakdown.
The utility model is made up of ash hole, circulation pipe, air blast, recovery nozzle etc., and reclaiming nozzle anterior is taper, stretches in the boiler furnace, and the upper back connects an end of circulation pipe, and afterbody connects air blast; The other end of circulation pipe is welded on the exit of funnel-form ash hole.
The utility model is by burning again that lime-ash is circulated, make the bagasse efficiency of combustion improve 30% than originally, the chimney black smoke obviously reduces, bulky grain combustible in the lime-ash reduces 90%, improved exerting oneself of boiler greatly, and prolonged the service life of equipment, especially received good environment protecting.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The utility model is on the basis of the bagasse pulverized-coal fired boiler in existing sugar refinery, increased by one and overlapped the burner again that circulates, form by ash hole, circulation pipe, air blast, recovery nozzle etc. as shown in Figure 1,4 places are welded with circulation pipe 1 at boiler 5 original funnel-form ash holes, one end of circulation pipe 1 connects recovery nozzle 2, the front portion of reclaiming nozzle 2 is taper, stretches in the boiler furnace, and afterbody connects air blast 3.The bagasse back unburned lime-ash completely that burns in boiler 5 along with flue gas rises, through plate washer, falls after rise at funnel-form ash hole 4 places, enters by circulation pipe 1 and reclaims nozzle 2, through air blast 3, the lime-ash high-speed jet is sprayed melt down thorax and burn.This burner again that circulates can be installed two covers or three covers according to existing two or three ash holes of boiler, makes full use of lime-ash and burns.The utility model all adopts metal material processing to form.
