Abstract
The utility model discloses a water-cooled grate with multiple wind chambers, which belongs to the field of boiler equipment and comprises a grate and wind chambers, wherein the three wind chambers are in unequal sizes and are divided into a preheating zone wind chamber, a main combustion zone wind chamber and a burnout zone wind chamber which are respectively and correspondingly positioned in a preheating zone, a main combustion zone and a burnout zone, a traditional large wind chamber is improved into three small wind chambers in different sizes, and the wind intake thereof is regulated according to the wind quantities required in the preheating zone, the main combustion zone and the burnout zone, so that fuel can be fully burnt.
Description
Technical field
The utility model relates to a kind of boiler corollary equipment, particularly a kind of water-cooled grate.
Background technology
The water-cooled vibrating-grate stoker is that the used novel stalk in a kind of thermal power plant directly burns formula boiler corollary equipment, is the best way of handling the crop straw burning generating at present.Water-cooled grate is the membrane wall that is made of cooling water pipe and band steel welding.Fire grate is divided into 2, and along boiler center line symmetric arrangement, fire grate is driven by mechanical device and vibrates; Be a wind scoop that is surrounded by two sides furnace wall and fire grate below the fire grate, provide wind-force to help the fuel combustion in the burner hearth by blower fan, concrete structure is referring to Fig. 1 and Fig. 2.When the burner hearth fuel combustion, generally be divided into 3 stages, i.e. preheating, main combustion and after-flame, three phases is taking place in three zones on fire grate from top to bottom respectively, promptly has preheating zone, primary zone and burning-out zone.But, big air compartment of the general employing of present this water-cooled grate, causing needing the place of a large amount of air in the burner hearth is that the primary zone does not have enough air, the place that does not need a large amount of air is that burning-out zone remains a large amount of air again, air quantity can not get rational allocation, cause that fuel can not fully burn in the combustion process, wind energy is wasted in a large number.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of novel water-cooled grate that wind energy makes full combustion of fuel that makes full use of.
The technical solution adopted in the utility model is such: a kind of windy chamber water-cooled grate, comprise fire grate and air compartment, and described air compartment is at least 2.
As preferably: described air compartment is 3.
As further preferred: described 3 air compartments differ in size.
As override: described 3 air compartments are divided into preheating zone air compartment, primary zone air compartment and burning-out zone air compartment, and correspondence is positioned at preheating zone, primary zone and burning-out zone respectively.
Owing to adopt technique scheme, the beneficial effects of the utility model are: a present big air compartment is improved to three little air compartments that vary in size, how much regulate its intake according to preheating zone, primary zone and burning-out zone institute required airflow, fuel can be fully burned.
Description of drawings
Fig. 1 is the utility model prior art constructions schematic diagram;
Fig. 2 is the side view of the utility model prior art;
Fig. 3 is the structural representation of the utility model embodiment.
Mark among the figure: 1 is furnace wall, and 2 is fire grate, and 3 are cloth wind inlet, and 4 is fuel inlet, and 5 is air compartment, and 6 is the preheating zone air compartment, and 7 is the primary zone air compartment, and 8 is the burning-out zone air compartment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 3, a kind of windy chamber water-cooled grate comprises fire grate 2 and 3 air compartments that vary in size, and these 3 air compartments are divided into preheating zone air compartment 6, primary zone air compartment 7 and burning-out zone air compartment 8, and correspondence is positioned at preheating zone, primary zone and burning-out zone respectively.
The same position of Yi Bian furnace wall 1 is provided with fuel inlet 4 and cloth wind inlet 3 therein, and fuel is sent into from fuel inlet 4, is that cloth wind is blown at cloth wind 3 places that enter the mouth simultaneously in the position identical with fuel inlet 4, and fuel is dispelled, and enters the stove internal combustion.
A present big air compartment is improved to three little air compartments that vary in size, how much regulate its intake according to preheating zone, primary zone and burning-out zone institute required airflow, fuel can be fully burned, regulative mode can adopt the mode of different air compartments with different blower fan air-supplies, primary zone air compartment 7 adopts more powerful blower fan, burning-out zone air compartment 8 adopts the bigger blower fan of power, and preheating zone air compartment 6 adopts the air compartment of mid power; In addition, regulative mode also can adopt on each ajutage control valve is set, and regulates intake, perhaps other regulative modes according to each air compartment needs.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
