Abstract
The invention discloses a wet-back fuel oil and exhaust gas combined boiler, which structurally comprises a boiler barrel. An exhaust gas inlet smoke box is arranged at the bottom in the boiler barrel, the upper end of the exhaust gas inlet smoke box is communicated with the bottoms of a plurality of boiler tubes, the tops of the plurality of boiler tubes are communicated with an upper smoke box, and an exhaust gas outlet is arranged on the upper smoke box. A fuel oil hearth is further arranged in the boiler barrel, the top of the fuel oil hearth is communicated with the bottom of a chimney, an outlet at the top of the chimney is communicated with the outside, a plurality of transverse water pipes communicated with the inside of the boiler barrel are arranged in the chimney, and the hearth bottom of the fuel oil hearth is arranged in the boiler barrel. The wet-back fuel oil and exhaust gas combined boiler has the advantages that the structure is simple, and the hearth bottom of the fuel oil hearth is arranged in the boiler barrel, thereby greatly increasing the radiation heating surface on the side of fuel oil and reducing production cost.
Description
Technical field
The present invention relates to the marine boiler field, relate in particular to the wetting back-type fuel oil waste gas combined boiler in the marine boiler.
Background technology
Fuel oil waste gas combined boiler comprises fuel oil side and exhaust gas side, the shared carbonated drink space of two parts, and fuel oil side and exhaust gas side can also can be moved simultaneously in isolated operation.The structure of traditional fuel oil waste gas combined boiler mainly comprises: drum; Bottom in the drum is provided with the exhaust gas inlet smoke box, and the upper end of exhaust gas inlet smoke box is connected with the bottom of some boiler tubes, and some boiler tubes top is connected with upper smoke box; Described upper smoke box is provided with waste gas outlet; Also be provided with the fuel oil burner hearth in the drum, the top of fuel oil burner hearth is connected with the bottom of chimney, and the top exit of described chimney is connected with the external world after going out drum; Be provided with some horizontal water tubes that are connected with drum inside in the described chimney, the burner hearth bottom of said fuel oil burner hearth is arranged in the exhaust gas inlet smoke box.Be full of stove water in the drum; And the burner hearth bottom of above-mentioned fuel oil burner hearth not with drum in the stove water contact, so above-mentioned fuel oil waste gas combined boiler is commonly called as and is dried back of the body formula fuel oil waste gas combined boiler, burner hearth is the radiation heating-surface of furnace fuel oil part; Because burner hearth bottom is arranged in the exhaust gas inlet smoke box; Burner hearth bottom can't carry out heat exchange with the stove water in the drum, and radiation heating-surface is long-pending less relatively, under the long-pending certain situation of total heating surface; Just need the height or the diameter of bigger fuel oil burner hearth, it is higher to increase the boiler manufacturing cost like this.
Summary of the invention
The objective of the invention is: a kind of wetting back-type fuel oil waste gas combined boiler that can improve the radiation heating-surface of fuel oil part is provided.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: wetting back-type fuel oil waste gas combined boiler, and its structure comprises: drum; Bottom in the drum is provided with the exhaust gas inlet smoke box, and the upper end of exhaust gas inlet smoke box is connected with the bottom of some boiler tubes, and some boiler tubes top is connected with upper smoke box; Described upper smoke box is provided with waste gas outlet; Also be provided with the fuel oil burner hearth in the drum, the top of fuel oil burner hearth is connected with the bottom of chimney, and the top exit of described chimney is connected with the external world; Be provided with some horizontal water tubes that are connected with drum inside in the described chimney, the burner hearth bottom of said fuel oil burner hearth is arranged in the drum.
Further, aforesaid wetting back-type fuel oil waste gas combined boiler, wherein, described burner hearth bottom is with the horizontal plane 5 degree angles that tilt and is provided with.
Advantage of the present invention is: simple in structure, the stove hall of fuel oil burner hearth bottom is arranged in the drum, and contact with stove water in the drum, increased the radiation heating-surface of fuel oil side greatly, reduced the production cost of boiler.
Description of drawings
Fig. 1 is the structural representation of wetting back-type fuel oil waste gas combined boiler of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed description.
As shown in Figure 1, wetting back-type fuel oil waste gas combined boiler, its structure comprises: drum 1; Bottom in the drum 1 is provided with exhaust gas inlet smoke box 2; The upper end of exhaust gas inlet smoke box 2 is connected with the bottom of some boiler tubes 3, and some boiler tubes 3 tops are connected with upper smoke box 4, and described upper smoke box 4 is provided with waste gas outlet 41; Also be provided with fuel oil burner hearth 5 in the drum 1; The top of fuel oil burner hearth 5 is connected with the bottom of chimney 6, and the top exit of described chimney 6 is connected with the external world, is provided with some horizontal water tubes 61 that are connected with drum 6 inside in the described chimney 6; The burner hearth bottom 51 of said fuel oil burner hearth 5 is arranged in the drum 1, and burner hearth bottom 51 is with the horizontal plane 5 degree angles that tilt and is provided with.
Operation principle of the present invention: when wetting back-type fuel oil waste gas combined boiler uses; The fuel oil side; The heat that oil inflame in the fuel oil burner hearth 5 produces passes to the stove water in the drum 1 through the burner hearth bottom 51 of fuel oil burner hearth 5 and all the other hearth walls of fuel oil burner hearth 5, and the high-temperature flue gas that produces in the fuel oil burner hearth 5 discharges from chimney 6; Also be provided with the horizontal water tube 61 that is connected with drum 1 in the chimney 6; In the process that high-temperature flue gas is upwards discharged heat is passed to horizontal water tube 61, horizontal water tube 61 is again with heat transferred stove water, because burner hearth bottom 51 is arranged to and the horizontal plane 5 degree angles that tilt; The steam of the stove water generates under the burner hearth bottom 51 is discharged along the burner hearth bottom that tilts 51 easily like this, has significantly reduced the impact that burner hearth bottom 51 is formed because of the steam delay; Exhaust gas side, high-temp waste gas gets into from exhaust gas inlet smoke box 2, and 3 rows advance upper smoke box 4 through boiler tube, and high-temp waste gas is with heat transferred boiler tube 3 in this process, and boiler tube 3 is again with the stove water in the heat transferred drum 1, and the waste gas after temperature reduces is discharged from waste gas outlet 41; The exhaust gas side and the fuel oil side of above-mentioned wetting back-type fuel oil waste gas combined boiler can be worked simultaneously, also can work independently.
Because the fuel oil bottom 51 of the fuel oil burner hearth 5 of fuel oil side is arranged in the drum 1; The lateral wall of whole like this fuel oil burner hearth 5 directly contacts with stove water; Increased the radiation heating-surface of fuel oil side greatly; The height of fuel oil burner hearth 5 or the size of diameter just can design lessly relatively under the long-pending certain situation of total heating surface, and the boiler manufacturing cost also can reduce greatly like this.
