Abstract
The utility model discloses a kind of boiler steam temperature regulation system, including superheater group and reheater group, the some vapor of superheater group and the superheated steam of reheater group and reheated steam outlet is connected to water at low temperature heat exchanger, water at low temperature heat exchanger is parallel to economizer, when overheated vapour is by superheater group, not only by overheated attemperator, also part accesses water at low temperature heat exchanger, when reheating vapour is by reheater group, not only by reheating attemperator, also part accesses water at low temperature heat exchanger, a feedwater part passes through economizer, it is partly into water at low temperature heat exchanger, in water at low temperature heat exchanger, respectively superheated steam and reheated steam are carried out heat exchange, final and economizer exit assemble jamming is to subordinate's heater.This utility model can equalize the temperature between different heating surface, it is possible to the heat exchange amount between the different heating surfaces such as regulation radiation, convection current, improves coal, the adaptability of load, reduces the energy loss during temperature regulation.
Description
[technical field]
This utility model belongs to field of thermal power, is specifically related to a kind of boiler steam temperature regulation system.
[background technology]
The regulative mode of vapor (steam) temperature is broadly divided into two big classes: fume side regulates and steam tempering.During fume side regulation,
The general modes such as regulating burner pivot angle, flue gas recirculation, regulation gas baffle that uses, the degree of regulation of vapor (steam) temperature is poor；
Mainly using the mode of attemperator during steam tempering, temperature regulation is the finest.General two ways uses, with flue gas simultaneously
Side regulation carrys out coarse adjustment as thermoregulator major way, using steam tempering as thin tuning, thus reaches boiler export
The purpose of vapor (steam) temperature regulation.
But, limited by boiler structure, fume side regulation range of accommodation limited, especially when coal type change scope relatively
Time big, regulation more difficulty.Along with the development of current energy-saving and emission-reduction situation, steam turbine reformation proposes significantly change feed temperature
Demand, also to boiler steam temperature regulation propose requirements at the higher level.
And steam tempering is due to needs desuperheating water, unit recycling economy there is considerable influence.
[utility model content]
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of boiler steam temperature regulation system, can not only
Enough fine regulation vapor (steam) temperatures, and can adapt to the various factors change impacts such as coal, load, feed temperature, and reduce
The energy loss caused because of desuperheating water regulation temperature.
In order to achieve the above object, this utility model includes superheater group and reheater group, superheater group and reheater group
Superheated steam and reheated steam outlet some vapor be connected to water at low temperature heat exchanger, water at low temperature heat exchanger is parallel to province's coal
Device.
It is provided with overheated desuperheating water between described superheater group and water at low temperature heat exchanger.
It is provided with reheating desuperheating water between described reheater group and water at low temperature heat exchanger.
Described superheater group accesses overheated vapour.
Described reheater group accesses reheating vapour.
Described superheater group, reheater group and economizer are placed in exhaust gases passes.
Described superheater group includes that multiple superheater, reheater group include multiple reheater.
Compared with prior art, the steam in this utility model passes through superheater group and reheater group is by water at low temperature heat exchanger
In water heating after, make own temperature reduce, thus reach regulation vapor (steam) temperature purpose, this utility model can equalize difference
Temperature between heating surface, it is possible to the heat exchange amount between the different heating surfaces such as regulation radiation, convection current, improves coal, the adaptability of load,
Reduce the energy loss during temperature regulation.
Further, this utility model is still provided with desuperheating water, it is possible to when, temperature not enough in heat exchange is too high, to steam
Lower the temperature.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is described further.
Seeing Fig. 1, this utility model includes the overheated of superheater group 1 and reheater group 2, superheater group 1 and reheater group 2
The some vapor of steam and reheated steam outlet is connected to water at low temperature heat exchanger 3, and water at low temperature heat exchanger 3 is parallel to economizer 4, mistake
It is provided with overheated desuperheating water 5 between hot device group 1 and water at low temperature heat exchanger 3, is provided with again between reheater group 2 and water at low temperature heat exchanger 3
Hot desuperheating water 6, superheater group 1 accesses overheated vapour, and reheater group 2 accesses reheating vapour, superheater group 1, reheater group 2 and economizer
4 are placed in exhaust gases passes, and superheater group 1 includes that multiple superheater, reheater group 2 include multiple reheater.
Method of work of the present utility model, when overheated vapour is by superheater group 1, not only by overheated attemperator 5, also part
Accessing water at low temperature heat exchanger 3, when reheating vapour is by reheater group 2, not only by reheating attemperator 6, also part accesses water at low temperature
Heat exchanger 3, a feedwater part, by economizer 4, is partly into water at low temperature heat exchanger 3, the most right in water at low temperature heat exchanger 3
Superheated steam and reheated steam carry out heat exchange, and final and economizer exit assemble jamming is to subordinate's heater；By the mistake after heat exchange
Vapours eventually flows to next equipment；Next equipment is eventually flowed to by the reheated steam after heat exchange.
