Abstract
The utility model discloses a hot-pipe atmospheric hot-water boiler which is composed of a coal bucket, a boiler arch, a grate, a main body, pipe bundles of a hot pipe, and a boiler wall, wherein, convective pipe bundles on both sides of the main body are welded with fin sheets, and a smoke and gas passage is surrounded by the fin sheets and the boiler wall. The left end of a boiler barrel forms the smoke and gas passage from a boiler cavity to a burning chamber through a smoke pipe on the boiler barrel to the left end of the hot-pipe atmospheric hot-water boiler finally through smoke passages on both sides to an outlet. A hot pipe is arranged in the smoke passages, and the upper end of the hot pipe extends into the boiler barrel. A self control water tank which is communicated with the main body is arranged behind the main body. The utility model combines the techniques of the hot pipe and a hot boiler together and has the advantage of small size.
Description
The utility model belongs to the combustion apparatus that uses solid fuel, and relates to a kind of heat pipe-type normal-pressure hot-water boiler.
Existing hot-water boiler, big, the inefficient problem of ubiquity heat loss.Main cause is that boiler body heating surface and flue gas flow design are unreasonable, and fuel combustion institute liberated heat can not as much as possible be absorbed by boiler body, and fume afterheat can not be used effectively.Particularly with the boiler of smoke pipe, its smoke pipe all is a common steel tube, and area of dissipation is limited.In order to address these problems, people just utilize the convection banks of arranging more, increase the way of heating surface.The result who does like this makes the boiler cost improve on the one hand, has also increased the volume of boiler body on the other hand, and its floor space is increased, and also is not easy to maintenance simultaneously.Hot pipe technique is the new technology of rising in recent years, has the high characteristics of the fast efficient of heating, is mainly used in recovery waste heat at present.
The purpose of this utility model is that hot pipe technique and boiler are combined, and provides that a kind of floor space is little, volume is little, and flue gas flow is reasonable, and the high heat pipe-type normal-pressure hot-water boiler of bigger suction radiating surface, efficient is arranged.
The utility model is made up of coal bunker, chimney arch, fire grate, boiler body, heat pipe tube bank and furnace wall, both sides surround exhaust gases passes by the fin and the furnace wall that are welded in the convection bank of both sides before and after body of heater, drum left end and furnace wall also surround gas flue, form one by burner hearth to secondary furnace, smoke pipe on drum arrives the exhaust gases passes of outlet then to the stove left end through the flue of both sides; In the passage of both sides, be furnished with heat pipe, the heat pipe upper end, promptly release end of heat extend in the drum; On the right side of stove body, an autocontrol tank that is connected with boiler body is arranged.
The utility model has the advantages that:, its thermal efficiency is significantly increased owing in boiler body, arranged heat pipe.Because the smoke pipe outer surface adopts screw-like, so just under the prerequisite that does not increase boiler volume, increased radiating surface again.In addition, flue gas flow is also more reasonable.After tested, the thermal efficiency can reach 80.5%.
Fig. 1 is a front view of the present utility model;
Fig. 2 is A-A cutaway view of the utility model Fig. 1;
Fig. 3 is B-B cutaway view of the utility model Fig. 1.
Describe in detail below in conjunction with accompanying drawing.
The utility model has a boiler body, and said boiler body has two lower collecting box 11 and a drum 4, and the convection bank 8 of both sides and afterbody convection bank 12 are communicated with drum 4 and lower collecting box 11; On the pipe of both sides convection bank 8, be welded with fin 13.On drum 4, smoke pipe 5 is installed, the outer surface of said smoke pipe 5 is a screw-like, so just can increase the area of dissipation of smoke pipe.Below boiler body, a fire grate 1 is arranged, at the fire grate left end coal bunker 2 is arranged.Around boiler body, furnace wall and furnace roof are arranged with flame-proof thermal insulation material and common brick block.Be manufactured with a stove rear arch 10 with refractory material in stove, this rear arch adopts ordinary people's font rear arch, but changes to some extent dimensionally, and promptly left side section shortens, and right section increases, and can give full play to the reflex of rear arch like this.Rear arch is divided into combustion chamber and secondary furnace two parts with burner hearth, at wall place, stove left side, is shaped on a face arch that cooperates with rear arch 3 with refractory cement.Form two flues in drum 4 both sides by the fin 13 and the furnace wall that are welded on the water-cooling wall pipe.In this flue, also be furnished with heat pipe tube bank 9.Said heat pipe is restrained 9 upper ends, is that release end of heat is welded in the drum that the lower end hangs; Also surround an exhaust gases passes in the drum left side with furnace wall, this exhaust gases passes communicates with the flue of stove both sides; A water tank 6 that is connected with the boiler body lower collecting box is arranged on the body right side;
When fuel fall from coal bunker on the fire grate ignited after, in the burner hearth internal combustion, hot flue gas enters secondary furnace between the rear arch in the past, wash away the convection bank 12 that is arranged in the body afterbody, return the stokehold from the smoke pipe 5 of afterbody on drum then, said smoke pipe 5 outer surfaces have screw-like, have so just increased the area of dissipation of smoke pipe.The flue gas that arrives the stokehold to the both sides shunting enter the flue of stove both sides and wash away the convection bank 8 of both sides and heat pipe tube bank 9 backs to outlet, heat pipe tube bank 9 is behind hot sweep of gases, its release end of heat heat release and smoke pipe on being installed in drum 5 that extend in the drum heats the water in the drum, so just can effectively utilize flue gas heat.
During use drum is communicated with the water inlet of system, water tank is communicated with return pipe, and stove when work, intrinsic water is heated rising through exporting to the user, and backwater arrives water tank and constantly replenishes intrinsic water.
Claims (2)
1, a kind of heat pipe-type normal-pressure hot-water boiler, form by coal bunker, chimney arch, fire grate, boiler body, heat pipe tube bank and furnace wall, in the convection bank of body both sides, be welded with fin, it is characterized in that: in body of heater, surround exhaust gases passes by the fin and the furnace wall that are welded in the convection bank, the drum left end also surrounds exhaust gases passes with furnace wall and communicates with the flue of both sides, front and back, to secondary furnace, the smoke pipe on drum is to the stove left end by burner hearth in formation, and last translateral flue is to the exhaust gases passes of outlet; Heat pipe is arranged in the flue, and the heat pipe upper end is that release end of heat extend in the drum; On stove body right side, a water tank that is connected with boiler body is arranged.
2, heat pipe-type normal-pressure hot-water boiler according to claim 1 is characterized in that: the smoke pipe outer surface that belongs to the drum inside of a body part is a screw-like.
