Abstract
The utility model discloses the oil burning boiler that a kind of horizontal burner hearth is arranged on drum outside, include burner, burner hearth, secondary furnace, drum, be arranged on the flue in drum and the water system containing water screen tube, wherein said burner is communicated with the burner hearth front end be arranged on outside drum, the rear end of burner hearth is connected with secondary furnace front end, and secondary furnace rear end is connected with flue.The utility model provides as comparatively low heating value fuel oil good burning situation in burner hearth, because burner hearth arranges outside stove cylinder, not surround by water at low temperature, burning thus can be made to carry out under required hot environment, for heat exchange provides qualified high-temperature flue gas, improve the heat transfer efficiency of boiler.Meanwhile, which simplify drum internal structure, reduce drum volume, save raw material and make man-hour, structure is simplified more, designing more rationally, reducing the cost of boiler, and be particularly suitable for using comparatively low heating value oil product.
Description
Technical field
The utility model belongs to industry, civil boiler field, specifically refers to that a kind of horizontal burner hearth is arranged on the oil burning boiler of drum outside.
Background technology
At present, usual used horizontal oil-firing boiler is all structurally that burner hearth is arranged on drum inside, and concrete structure is by flue as in drum, and is arranged in parallel with drum, burner is placed in the front end of flue, and namely the inner chamber of flue is burner hearth.The oil burning boiler of this traditional structure has compact conformation, heat transfer efficiency advantages of higher, but because the burner hearth in flue is arranged in drum, the outside of burner hearth surround by boiler water, when burning low heating value fuel oil, the temperature of burner hearth is not ideal enough, do not reach designing requirement, cause burning insufficient, required high-temperature flue gas can not be provided for heat exchange, thus affect exerting oneself of boiler.Existing traditional structure is complicated simultaneously, and manufacturing process difficulty is large, boiler added cost.
Now, the oil burning boiler that horizontal burner hearth is arranged on drum inside is widely used, but due to when using calorific capacity lower fuel oil combustion efficiency undesirable, impact heats up, and even boiler output is not enough, needs a kind of being applicable to use the boiler compared with low heating value fuel oil.
Summary of the invention
The purpose of this utility model is to overcome prior art deficiency, and provides a kind of structure more to simplify, designs more rationally, is applicable to using the oil burning boiler being arranged on drum outside compared with the horizontal burner hearth of low heating value oil product.
The purpose of this utility model is achieved in that
A kind of horizontal burner hearth is arranged on the oil burning boiler of drum outside, include burner, burner hearth, secondary furnace, drum, be arranged on the flue in drum and the water system containing water screen tube, wherein said burner is communicated with the burner hearth front end be arranged on outside drum, the rear end of burner hearth is connected with secondary furnace front end, and secondary furnace rear end is connected with flue.
Further, described burner hearth is built by laying bricks or stones by refractory brick and refractory concrete and is formed.
Further, described flue is made up of the first bundle smoke pipe and the second bundle smoke pipe, drum two ends are provided with front tube sheet, back tube sheet, first bundle smoke pipe is fixedly connected with front tube sheet with one end of the second bundle smoke pipe, the other end is fixedly connected with back tube sheet, first bundle smoke pipe one end is connected with secondary furnace rear end, the first bundle smoke pipe other end is connected with the rear smoke chamber that drum rear end is arranged, rear smoke chamber restraints smoke pipe with second simultaneously and is connected, the second bundle smoke pipe other end is connected with the front smoke chamber being arranged on drum front end, and front smoke chamber is connected with outlet flue.
Further, described front smoke chamber be by drum outside the die cavity that jointly synthesizes of heat-insulation layer, flame retardant coating and front tube sheet form, the die cavity that described rear smoke chamber is synthesized jointly by the heat-insulation layer outside drum, flame retardant coating and back tube sheet is formed.
Further, described secondary furnace is by drum bottom outer wall, and the die cavity that outside drum and burner hearth, the heat-insulation layer of ecto-entad, flame retardant coating, water screen tube and front tube sheet synthesize jointly is formed.
Further, described water system is made up of water screen tube, front canopy pipe, front header, side header, drum, water screen tube one end and drum seam, the other end and side header seam, front canopy pipe one end and drum seam, the other end and front header seam, front header and side header are communicated by tube connector seam, the die cavity that common formation is airtight, forms boiler water system.
Creation point of the present utility model is that described horizontal burner hearth is located at drum outside, change traditional horizontal oil-firing boiler and burner hearth is arranged on way in drum, eliminate flue, boiler structure is simplified more, rationally, drum inner space becomes looser, thus can reduce drum diameter, namely saves raw material, in turn save manufacturing man-hours, reduce boiler cost.The horizontal burner hearth of the utility model is arranged on the outside oil burning boiler of drum, its distinctive feature is burner hearth to take out in drum, use the materials and process that refractory brick and refractory concrete are built by laying bricks or stones instead, make when using low heat value fuel oil, burner hearth is not affecting burning process because steel furnace is surrounded by water, and for the extensive use of low heat value fuel oil provides condition, thus when making to use calorific capacity lower fuel oil, combustion efficiency is desirable, be rapidly heated, promote boiler output.
