Description
Technical field
The present invention relates to a kind of method of heating furnace, particularly the method for the hot Secondary Air heating furnace of a kind of adjacent stove and device.
Background technology
At present, in ciculation fluidized bed operating, boiler cold-state starts, and the factors such as Secondary Air temperature is low, and fire box temperature is low, substantially prolongs the start-up time of boiler, cause fuel consumption to increase, and adds payment for initiation and uses.
Summary of the invention
Technical problem to be solved by this invention is in actual motion, how to shorten the existing boiler startup time, reduces and starts fuel consumption, cost-effective key issue.
For this purpose, the present invention proposes the method for the hot Secondary Air heating furnace of a kind of adjacent stove, comprise the steps:
S1: at the normal boiler run, i.e. the first boiler and the boiler preparing to start, namely the porch of the second boiler installs communicating pipe additional, wherein, communicating pipe is equipped with adjustable gate;
S2: when described second boiler startup, regulates the adjustable gate on described communicating pipe to make described first boiler provide hot Secondary Air for described second boiler.
Particularly, in described first boiler and described second boiler normally run, described adjustable gate is closed condition.
Particularly, during described second boiler startup, described adjustable gate is opening.
For this purpose, the invention allows for the device of the hot Secondary Air heating furnace of a kind of adjacent stove, comprising:
The boiler of normal operation, i.e. the first boiler; Prepare the boiler started, i.e. the second boiler; Communicating pipe; Adjustable gate; The air preheater that operating boiler is corresponding, i.e. described first boiler preheater; The air preheater that the boiler preparing to start is corresponding, i.e. described second boiler preheater;
Wherein, described first boiler preheater and described second boiler preheater secondary air channel place is arranged at described communicating pipe; Described communicating pipe is equipped with described adjustable gate.
Particularly, during described first boiler and described second boiler normally run, described adjustable gate is closed condition.
Particularly, during described second boiler startup, described adjustable gate is opening.
The method of the hot Secondary Air heating furnace of a kind of adjacent stove disclosed by the invention, by adjacent two boilers, on the air preheater outlet Secondary Air pipeline of its correspondence, installs a communicating pipe additional, and on communicating pipe, control valve is housed, the size of quantity-adjustable.When boiler cold-state starts, operating boiler hot Secondary Air air quantity slowly increases, the size of controlling opening of valve, for preparing the boiler started, provides hot Secondary Air.On the one hand, be unlikely to the normal boiler run, air quantity reduces suddenly, causes unstable combustion; Also the boiler air quantity being unlikely on the other hand to prepare to start increases suddenly, and damage equipment, has security, high efficiency and applicability.The invention also discloses the device of the hot Secondary Air heating furnace of a kind of adjacent stove.
Accompanying drawing explanation
Can understanding the features and advantages of the present invention clearly by reference to accompanying drawing, accompanying drawing is schematic and should not be construed as and carry out any restriction to the present invention, in the accompanying drawings:
Fig. 1 shows the flow chart of the method for the hot Secondary Air heating furnace of a kind of adjacent stove in the embodiment of the present invention;
Fig. 2 shows the structure chart of the device of the hot Secondary Air heating furnace of a kind of adjacent stove in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
In order to shorten the existing boiler startup time, reducing and starting fuel consumption, save cost, the invention provides the device of the hot Secondary Air heating furnace of a kind of adjacent stove, this device is simple to operate, convenient, be applicable to initial start stage to use, and on tube connector, control valve be housed, quantity-adjustable number.
In order to better understand the method for the hot Secondary Air heating furnace of a kind of adjacent stove proposed with application the present invention, shown in composition graphs 1.
Step S1: at the normal boiler run, i.e. the first boiler and the boiler preparing to start, namely the porch of the second boiler installs communicating pipe additional, wherein, communicating pipe is equipped with adjustable gate.
Particularly, in the first boiler and the second boiler normally run, adjustable gate is closed condition.
Step S2: when the second boiler startup, regulates the adjustable gate on communicating pipe to make the first boiler provide hot Secondary Air for the second boiler.
Particularly, during the second boiler startup, adjustable gate is opening.
For realizing shortening the existing boiler startup time, reducing and starting fuel consumption, saving cost, the invention allows for the device of the hot Secondary Air heating furnace of a kind of adjacent stove, as shown in Figure 2.
Particularly, the normal boiler run, i.e. the first boiler (1); Prepare the boiler started, i.e. the second boiler (2); Communicating pipe (3); Adjustable gate (4); The air preheater that operating boiler is corresponding, i.e. described first boiler preheater (5); The air preheater that the boiler preparing to start is corresponding, i.e. described second boiler preheater (6).Wherein, the first boiler preheater (5) and the second boiler preheater (6) secondary air channel place is arranged at communicating pipe (3); Be equipped with adjustable gate (4) communicating pipe (3), thus, play the useful effect of regulating air volume.
Further, during the first boiler (1) and the second boiler (2) normally run, adjustable gate (4) is closed condition; When first boiler (1) or the second boiler (2) start, adjustable gate (4) is opening, the i.e. normal boiler run, namely the first boiler (1) is the boiler preparing to start, namely the second boiler (2) provides hot Secondary Air, the boiler hearth temperature preparing to start can be heated rapidly, effectively shorten the start-up time of boiler.Thus, shorten the existing boiler startup time, reduce and start fuel consumption, save cost.
The method of the hot Secondary Air heating furnace of a kind of adjacent stove disclosed by the invention, by adjacent two boilers, on the air preheater outlet Secondary Air pipeline of its correspondence, installs a communicating pipe additional, and on communicating pipe, control valve is housed, the size of quantity-adjustable.When boiler cold-state starts, operating boiler hot Secondary Air air quantity slowly increases, the size of controlling opening of valve, for preparing the boiler started, provides hot Secondary Air.On the one hand, be unlikely to the normal boiler run, air quantity reduces suddenly, causes unstable combustion; Also the boiler air quantity being unlikely on the other hand to prepare to start increases suddenly, and damage equipment, has security, high efficiency and applicability.The invention also discloses the device of the hot Secondary Air heating furnace of a kind of adjacent stove.
Although describe embodiments of the present invention by reference to the accompanying drawings, but those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, such amendment and modification all fall into by within claims limited range.
