Description

The aciculiform pipe oil burning boiler of band energy saving economy device
Technical field
The utility model relates to the marine boiler field, relates in particular to a kind of aciculiform pipe oil burning boiler in the marine boiler.
Background technology
For reducing smoke contamination, protect atmospheric environment, oil burning boiler replaces coal-burning boiler gradually, and the oil burning boiler floor space is little, the thermal efficiency is high, automaticity is high.But the operating cost of oil burning boiler is high, therefore improves the oil burning boiler economic operation level, is that the oil burning boiler consumption reduction is put forward the new problem that effect faces.
Aciculiform pipe oil burning boiler is a kind of through the various fuel of burning, makes the heat that discharges pass through diabatic process with heat transferred water, makes water be transformed into a kind of heat transmission equipment of steam.The structure of traditional aciculiform pipe oil burning boiler mainly comprises: housing; Enclosure interior is provided with burner hearth; Roof of the furnace is connected with some aciculiform pipe assemblies, and described case top is provided with smoke box, and the top of described aciculiform pipe assembly is connected with smoke box; Be connected with smoke discharging pipe on the described smoke box, described case top also is provided with steam (vapor) outlet.In use, the flue gas that the burner hearth fuel combustion produces enters into aciculiform pipe assembly, and passes through aciculiform pipe assembly with the water in most of heat transferred housing, and rising enters into smoke box, directly discharges the smoke discharging pipe from smoke box then.Because the working medium temperature in the evaporating heating surface equals the saturation temperature of working medium under operating pressure, flue-gas temperature must not be lower than or reach this temperature, and flue-gas temperature and saturation temperature must keep certain temperature difference, could effectively transmit heat.So the flue-gas temperature that the smoke discharging pipe from smoke box is discharged is still very high, generally has 300 ℃ ~ 400 ℃, and the flue gas of such high temperature is directly discharged, and obviously is uneconomic.
The utility model content
The purpose of the utility model is: a kind of aciculiform pipe oil burning boiler that can effectively utilize the fume afterheat of from smoke box, discharging is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: the aciculiform pipe oil burning boiler of band energy saving economy device, and its structure mainly comprises: housing; Enclosure interior is provided with burner hearth, and roof of the furnace is connected with some aciculiform pipe assemblies, and described case top is provided with smoke box; The top of described aciculiform pipe assembly is connected with smoke box, and described case top also is provided with steam (vapor) outlet, is connected with the energy saving economy device on the described smoke box; The structure of described energy saving economy device comprises: energy saving economy device housing; Energy saving economy device housing bottom is connected with smoke box, is connected with discharge duct on the energy saving economy device housing, is provided with coiled pipe in the energy saving economy device housing; The last interface of described coiled pipe is connected with feed pipe, the lower interface of described coiled pipe and housing intracavity inter-connection.
The utility model has the advantages that: owing on the smoke box at aciculiform pipe oil burning boiler top, be provided with the energy saving economy device; The heat that stove water is introduced in the coiled pipe in the energy saving economy device from the feedwater interface, also absorption enters into the high-temperature flue gas in the energy saving economy device housing from smoke box; And then enter in the housing of boiler, the temperature of the high-temperature flue gas of from smoke box, discharging simultaneously reduces the back and discharges the energy saving economy device.Make full use of the waste heat of flue gas in the smoke box like this, reduced the heat energy loss, improved the economic operation level of aciculiform pipe oil burning boiler, reduced the operating cost of aciculiform pipe oil burning boiler.
Description of drawings
Fig. 1 is the structural representation of the aciculiform pipe oil burning boiler of the described band energy saving economy of the utility model device.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to specify.
As shown in Figure 1, the aciculiform pipe oil burning boiler of band energy saving economy device, its structure mainly comprises: housing 1; Housing 1 set inside has burner hearth 2, and burner hearth 2 tops are connected with some aciculiform pipe assemblies 4, and described housing 1 top is provided with smoke box 5; The top of described aciculiform pipe assembly 4 is connected with smoke box 5, and the top of described housing 1 also is provided with steam (vapor) outlet 9, is connected with the energy saving economy device on the described smoke box 5; The structure of described energy saving economy device comprises: energy saving economy device housing 6; The bottom of energy saving economy device housing 6 is connected with smoke box 5, is connected with discharge duct 7 on the energy saving economy device housing 6, is provided with coiled pipe 8 in the energy saving economy device housing 6; The last interface 81 of described coiled pipe 8 is connected with feed pipe, the lower interface 82 of described coiled pipe 8 and the intracavity inter-connection of housing 1.
The operation principle of the utility model is following: when the aciculiform pipe oil burning boiler of band energy saving economy device is worked; The heat that burner hearth 2 internal combustion produce is directly passed to the stove water in the housing 1; In the flue gas entering aciculiform pipe assembly 4 that produces in the burner hearth 2 and with the stove water in a part of heat transferred housing 1; From aciculiform pipe assembly 4, rise in the smoke box 5 flue gas and continue upwards to the energy saving economy device, flue gas is with the stove water in the heat transferred coiled pipe 8, and the feedwater interface is connected with the last interface 81 of coiled pipe 8; The stove water of need supply flow to the lower end the energy saving economy device from the upper end of energy saving economy device like this; Form adverse current with flue gas to the trend that rises, flue gas is better with the water in the heat transferred coiled pipe 8, and the water that was heated that flows out from the lower interface 82 of coiled pipe 8 gets in the housing 1 again.Stove water in the housing 1 is discharged from steam (vapor) outlet 9 by the steam of thermosetting.
The utility model has the advantages that: owing on the smoke box 5 at aciculiform pipe oil burning boiler top, be provided with the energy saving economy device; Need the stove water of supply from the last interface 81 of coiled pipe 8, to be introduced in the coiled pipe 8 in the energy saving economy device, also absorb the heat that enters into the high-temperature flue gas in the energy saving economy device housing 6 from smoke box 5; And then enter in the housing 1 of boiler, the temperature of the high-temperature flue gas of from smoke box 5, discharging is simultaneously discharged the energy saving economy device after reducing again.Make full use of the waste heat of flue gas in the smoke box 5 like this, reduced the heat energy loss, improved the economic operation level of aciculiform pipe oil burning boiler, reduced the operating cost of aciculiform pipe oil burning boiler.
