Abstract
The utility model relates to the device of the hot Secondary Air heating furnace of a kind of adjacent stove, comprising: the normal boiler run, 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.The utility model, by two adjacent 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.There is security and practicality.
Description
Technical field
The utility model relates to a kind of heater, particularly the device of the hot Secondary Air heating furnace of a kind of adjacent stove.
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.
Utility model content
Technical problem to be solved in the utility model 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 utility model proposes 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 device of the hot Secondary Air heating furnace of a kind of adjacent stove disclosed in the utility model, by adjacent two boilers, on the air preheater outlet Secondary Air pipeline of its correspondence, install 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 and practicality.
Accompanying drawing explanation
Can understanding feature and advantage of the present utility model clearly by reference to accompanying drawing, accompanying drawing is schematic and should not be construed as and carry out any restriction to the utility model, in the accompanying drawings:
Fig. 1 shows the structure chart of the device of the hot Secondary Air heating furnace of a kind of adjacent stove in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In order to shorten the existing boiler startup time, reducing and starting fuel consumption, save cost, the utility model provides the device of the hot Secondary Air heating furnace of a kind of adjacent stove, and 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 and the device applying the hot Secondary Air heating furnace of a kind of adjacent stove that the utility model proposes, shown in composition graphs 1.
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 device of the hot Secondary Air heating furnace of a kind of adjacent stove disclosed in the utility model, by adjacent two boilers, on the air preheater outlet Secondary Air pipeline of its correspondence, install 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 and practicality.
Although describe embodiment of the present utility model by reference to the accompanying drawings, but those skilled in the art can make various modifications and variations when not departing from spirit and scope of the present utility model, such amendment and modification all fall into by within claims limited range.
