Abstract

The utility model provides a blast furnace gas boiler superheater layout structure. The requirement of high-pressure high-temperature parameters can be met after superheaters and an economizer are arranged, heat produced by combustion can be fully utilized, and energy source can be saved. The blast furnace gas boiler superheater layout structure comprises a hearth, a horizontal flue, a vertical flue, the superheaters and the economizer, wherein the inlet section of the horizontal flue is arranged above the hearth; and the outlet end of the horizontal flue is communicated with the vertical flue. The blast furnace gas boiler superheater layout structure is characterized in that the superheaters comprise a high-temperature superheater, a medium-temperature superheater and a low-temperature superheater; the high-temperature superheater and the medium-temperature superheater are arranged in the horizontal flue in sequence; the low-temperature superheater is arranged in the upper section of the vertical flue; the economizer is arranged under the low-temperature superheater; saturated vapor on the top of a boiler drum is communicated to an inlet header of the low-temperature superheater through a connecting pipe; and an outlet header of the low-temperature superheater is communicated to an inlet header of the medium-temperature superheater through a pipeline after being connected to a first-stage spray type desuperheater.

Description

A kind of blast furnace gas boiler superheater arrangement
Technical field
The utility model relates to the technical field of structures of blast furnace gas boiler, is specially a kind of blast furnace gas boiler superheater arrangement.
Background technology
Because the blast furnace gas calorific capacity is extremely low, a little less than the Fire Radiation ability, radiation heat absorption capacity wretched insufficiency in the burner hearth, a large amount of caloric requirements absorb by back-end surfaces, but in order to control the boiling rate of economizer exit, can not arrange too much economizer area again; Existing blast furnace gas boiler, the superheater of its layout, economizer can not satisfy the demand of HTHP parameter, and the heat that makes burning produce can not be fully utilized, waste energy.
Summary of the invention
At the problems referred to above, the utility model provides a kind of blast furnace gas boiler superheater arrangement, and it makes superheater, the postpone of economizer cloth can satisfy the demand of HTHP parameter, and the heat that makes burning produce is fully used energy savings.
A kind of blast furnace gas boiler superheater arrangement, its technical scheme is such: it comprises burner hearth, horizontal flue, vertical flue, superheater, economizer, the top of described burner hearth is the entrance of horizontal flue, the port of export of described horizontal flue is communicated with described vertical flue, it is characterized in that: described superheater comprises high temperature superheater, medium temperature overheater, low temperature superheater, described high temperature superheater, medium temperature overheater is arranged in the described horizontal flue in turn, described low temperature superheater is arranged in the epimere of described vertical flue, the below of described low temperature superheater is provided with described economizer, the saturated vapor at drum top is communicated to the entrance collection case of described low temperature superheater by tube connector, the outlet collection case of described low temperature superheater connects behind the one-level direct-contact desuperheater by the entrance collection case of pipeline connection to described medium temperature overheater, the outlet collection case of described medium temperature overheater is introduced the entrance collection case that is communicated to described high temperature superheater behind the secondary direct-contact desuperheater by pipeline, and the outlet collection case of described high temperature superheater is by the collection vapour collection case of pipeline connection outside.
It is further characterized in that: the coiled pipe counter-flow arrangement from entrance collection case to outlet collection case of described low temperature superheater;
Following current is arranged after the coiled pipe elder generation adverse current from entrance collection case to outlet collection case of described medium temperature overheater;
Following current is arranged after the coiled pipe elder generation adverse current from entrance collection case to outlet collection case of described high temperature superheater.
After adopting structure of the present utility model, the saturated vapor at drum top is communicated to the entrance collection case of low temperature superheater by tube connector, enter low temperature superheater outlet collection case then, behind the one-level direct-contact desuperheater, enter medium temperature overheater entrance collection case, enter medium temperature overheater outlet collection case then, introduce the secondary direct-contact desuperheater by pipeline, enter high temperature superheater entrance collection case behind the desuperheat, enter high temperature superheater outlet collection case then, this moment, steam reached the export amount fixed temperature of boiler, be connected to collection vapour collection case with tube connector more at last, owing to arranged three, and low superheater is arranged in the vertical gas pass, and it makes the area of the economizer that vertical gas pass is interior reduce relatively, has controlled the boiling rate of economizer exit, a large amount of heats are absorbed by superheater, it makes superheater, the postpone of economizer cloth can be satisfied the demand of HTHP parameter, and the heat that makes burning produce is fully used energy savings.
