Description
Technical field
The present invention relates to the fuel-oil waste-gas boilers in marine boiler field more particularly to marine boiler.
Background technique
Fuel-oil waste-gas combined boiler includes fuel oil side and exhaust gas side, and two parts share a carbonated drink space, fuel oil side and useless
Gas side can also be run simultaneously with isolated operation.The structure of traditional fuel-oil waste-gas combined boiler specifically includes that drum, in drum
Bottom be provided with exhaust gas inlet smoke box, the upper end of exhaust gas inlet smoke box is connected with the bottom of several boiler tubes, several boiler tube tops
Portion is connected with upper smoke box, and waste gas outlet is provided on the upper smoke box, and fuel oil burner hearth, fuel oil burner hearth are additionally provided in drum
Top be connected with the bottom of chimney, the top exit of the chimney is connected after going out drum with the external world, the chimney
Inside it is provided with several with horizontal water tube that is being connected inside drum, the burner hearth bottom of the fuel oil burner hearth is arranged in exhaust gas inlet smoke box
It is interior.Furnace water is full of in drum, and the burner hearth bottom of above-mentioned fuel oil burner hearth is not contacted with the furnace water phase in drum, thus it is above-mentioned
Fuel-oil waste-gas combined boiler is commonly called as dry back formula fuel-oil waste-gas combined boiler, and burner hearth is the radiation heating-surface of furnace fuel oil part,
Due to burner hearth bottom be arranged in exhaust gas inlet smoke box, burner hearth bottom can not with the furnace water in drum carry out heat exchange, radiation by
Heat area is relatively fewer, in the case where total heating surface product is certain, it is necessary to the height or diameter of biggish fuel oil burner hearth, in this way
It is higher to will increase boiler manufacture cost.
Summary of the invention
To achieve the above object, the technical solution adopted by the present invention is that: fuel-oil waste-gas boiler, structure include: drum, pot
Bottom in cylinder is provided with exhaust gas inlet smoke box, and the upper end of exhaust gas inlet smoke box is connected with the bottom of several boiler tubes, Ruo Ganlu
Tube top portion is connected with upper smoke box, and waste gas outlet is provided on the upper smoke box, fuel oil burner hearth, fuel oil are additionally provided in drum
The top of burner hearth is connected with the bottom of chimney, and the top exit of the chimney is connected with the external world, sets in the chimney
It is equipped with several with horizontal water tube that is being connected inside drum, the burner hearth bottom of the fuel oil burner hearth is arranged in drum.
Further, fuel-oil waste-gas boiler above-mentioned, wherein the burner hearth bottom is in tilt 5 degree of angles with horizontal plane to set
It sets.
The invention has the advantages that structure is simple, the furnace bottom of fuel oil burner hearth is arranged in drum, with the furnace in drum
Water phase contact, considerably increases the radiation heating-surface of fuel oil side, reduces the production cost of boiler.
Fig. 1 is the structural schematic diagram of fuel-oil waste-gas boiler of the present invention.
The following further describes the present invention in detail with reference to the accompanying drawings and preferred embodiments.
As shown in Figure 1, fuel-oil waste-gas boiler, structure includes: drum 1, and the bottom in drum 1 is provided with exhaust gas inlet cigarette
Case 2, the upper end of exhaust gas inlet smoke box 2 are connected with the bottom of several boiler tubes 3, and several 3 tops of boiler tube are connected with upper smoke box 4,
It is provided with waste gas outlet 41 on the upper smoke box 4, fuel oil burner hearth 5, the top of fuel oil burner hearth 5 and cigarette are additionally provided in drum 1
The bottom of cylinder 6 is connected, and the top exit of the chimney 6 is connected with the external world, is provided with several and pot in the chimney 6
The burner hearth bottom 51 of the horizontal water tube 61 being connected inside cylinder 6, the fuel oil burner hearth 5 is arranged in drum 1, and burner hearth bottom 51 is in
5 degree of angles are tilted with horizontal plane to be arranged.
The working principle of the invention: in use, fuel oil side, the fuel burning in fuel oil burner hearth 5 generates fuel-oil waste-gas boiler
Heat, the furnace water in drum 1 is passed to by the burner hearth bottom 51 of fuel oil burner hearth 5 and remaining hearth wall of fuel oil burner hearth 5, fire
The high-temperature flue gas generated in oil oven thorax 5 is discharged from chimney 6, and the horizontal water tube being connected with drum 1 is also provided in chimney 6
61, high-temperature flue gas transfers heat to horizontal water tube 61 during being discharged upwards, and horizontal water tube 61 transfers heat to Lu Shui again, by
In burner hearth bottom 51 is arranged to tilt 5 degree angles with horizontal plane, the easy edge of steam of the lower furnace water generation of such burner hearth bottom 51
Inclined burner hearth bottom 51 is discharged, and greatly reduces the impact formed because steam is detained to burner hearth bottom 51；Exhaust gas side, high temperature
Exhaust gas enters from exhaust gas inlet smoke box 2, discharges into upper smoke box 4 by boiler tube 3, and high-temp waste gas transfers heat to boiler tube during this
3, boiler tube 3 transfers heat to the furnace water in drum 1 again, and the exhaust gas after temperature reduces is discharged from waste gas outlet 41；Above-mentioned fuel oil
The exhaust gas side of exhaust boiler and fuel oil side are simultaneously operable, and also can work independently.
Due to being arranged the fuel oil bottom 51 of the fuel oil burner hearth 5 of fuel oil side in drum 1, fuel oil burner hearth 5 entire in this way
Lateral wall is directly contacted with furnace water, considerably increases the radiation heating-surface of fuel oil side, is fired in the case where total heating surface product is certain
The height of oil oven thorax 5 or the size of diameter can be designed relatively small, and such boiler manufacture cost also will be greatly reduced.
