Abstract

The utility model is composed of boiler wall 1, a mechanical grate 10, an upper coal bucket 12, a boiler arch 3, a heat exchange tube group 6, and a fire tube drum 7. The utility model is characterized in that the upper part of the boiler arch 3 is provided with a reignition smoke eliminating fire arch 8 to form a reignition chamber 85, the boiler body which is corresponding to the reignition chamber 85 is provided with a secondary air inlet 80. During the combustion, black smoke dust which is generated because of the insufficient combustion is further sufficiently burned when the black smoke dust passing through a reignition chamber 30 of the reignition fire arch 8, and thus the black smoke and dust is effectively eliminated.

Description

Horizontal reciprocal grate hot-water boiler

The utility model relates to coal-fired hot-water boiler.

Hot-water boiler has variedly in the prior art, and it is different that its each self-structure is configured with institute, each has its oneself characteristics and deficiency.

A kind of horizontal reciprocal grate hot-water boiler is arranged in the prior art, as the horizontal reciprocal grate hot-water boiler of KZG type, it is by the reciprocating machine fire grate device that its primary structure constitutes, the combustion chamber, the fiery baker arch of upper end, combustion chamber, the heating clamber on chimney arch top, reach the set of heat exchange tubes of sidepiece in the heating clamber, the fire tube drum that links to each other and be arranged on this upper of furnace body with this set of heat exchange tubes, the furnace wall body constitutes, fire grate combustion heating furnace arch during its work, chimney arch heat radiation heating clamber, the chimney arch of hot flue gas on the combustion chamber blocks, enter the heating clamber on its top from the chimney arch front portion, operation enters in the drum fire tube backward, the operation back discharges out of the furnace from exhaust opening in the drum fire tube, and exchange heat pipe and drum heat during flue gas fortune.This boiler is because its power is big, and many-sided combination properties such as operability, the thermal efficiency, cost are better, so be widely used at present.But the shortcoming of its existence is, its individual layer fire grate combustion system, and burning often can not be very abundant, and produce a large amount of black smokes and dust, so its use need be furnished with device for abatement of smoke and dust, could satisfy the general requirement of soot emissions.

Order of the present utility model ground is to improve at above-mentioned the deficiencies in the prior art, overcomes its shortcoming deficiency, provides a kind of smoke medicining dust-removing effect good horizontal reciprocal grate hot-water boiler.

Technical solution of the present utility model be above-mentioned promptly by furnace wall body 1, reciprocating machine fire grate device 10, on hod device 12, combustion chamber 2, chimney arch 3, stove pick out in the heating clamber 5, heating clamber on top and the set of heat exchange tubes 6 of sidepiece, on the basis of the horizontal reciprocal grate hot-water boiler that the fire tube drum 7 that is arranged on this upper of furnace body of linking to each other with this set of heat exchange tubes 6 constitutes, be provided with second layer chimney arch----smoke elimination sleeper fire arch 8 on the top of chimney arch 3, the bottom of corresponding smoke elimination sleeper fire arch 8 and the folder chamber between chimney arch 3 tops offer secondary air mouth 80 on body of heater 1.The utility model makes the black smoke flue dust that fully burns and produce when fire grate burns in the main chamber 2 by setting up sleeper fire arch 8, encircleing at 8 o'clock through sleeper fire by further abundant burning, eliminates the black smoke flue dust.

Fig. 1, the 2nd, structural representation of the present utility model, wherein Fig. 2 is the A-A cutaway view of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described.

The utility model includes in furnace wall body 1, reciprocating machine fire grate device 10, the heating clamber 5 of going up hod device 12, combustion chamber 2, chimney arch 3, chimney arch 3 tops, the heating clamber and the set of heat exchange tubes 6 of sidepiece, the fire tube drum 7 that is arranged on this upper of furnace body that links to each other with this set of heat exchange tubes 6 constitutes, it is characterized in that being provided with second layer chimney arch----smoke elimination sleeper fire on the top of chimney arch 3 encircles 8, form resume combustion chamber 85, the bottom of corresponding smoke elimination sleeper fire arch 8 and the folder chamber afterburner 85 between chimney arch 3 tops offer secondary air mouth 80 on body of heater 1.

Fire grate 10 combustion heating furnaces arch 3 during its work of the utility model, the chimney arch 3 of pyrotechnics on combustion chamber 2 blocks, upwards enter the afterburner 85 under the sleeper fire arch 8 from chimney arch 3 front portions, pyrotechnics heating sleeper fire arch 8, flue gas moves backward and enters in drum 7 fire tubes 70, in the drum fire tube from after operation forward, the flue gas operation backward of turning back in the smoke box 72 of drum 7 front portions in the past discharges out of the furnace from drum exhaust opening 75 then.The utility model fire grate 10 combustion

heating furnaces arch

3,8,

chimney arch

3,8 is the red heat state, produce heat radiation, afterburner 85 under the fire arch 8 is longer, and its interior temperature is very high, cooperates down by secondary wind air inlet 80 air feed oxygenation in afterburner 85, makes the black smoke flue dust that does not fully burn and produce when fire grates burn in the main chamber 2, further fully burning of quilt through the afterburner 85 under the sleeper fire arch 8 time, thus the black smoke flue dust eliminated effectively.

Claims

1, a kind of horizontal reciprocal grate hot-water boiler, include furnace wall body (1), reciprocating machine fire grate device (10), last hod device (12), combustion chamber (2), chimney arch (3), the heating clamber (5) on chimney arch (3) top, in the heating clamber and the set of heat exchange tubes (6) of sidepiece, the fire tube drum (7) that is arranged on this upper of furnace body that links to each other with this set of heat exchange tubes (6) constitutes, it is characterized in that being provided with second layer chimney arch----smoke elimination sleeper fire on the top of chimney arch (3) encircles (8), form resume combustion chamber (85), the bottom of corresponding smoke elimination sleeper fire arch (8) and the folder chamber afterburner (85) between chimney arch (3) top offer secondary air mouth (80) on body of heater (1).
