Abstract
The utility model relates to a fire grate, in particular to an admission regulator of the fire grate. The admission regulator of fire grate relates to the fire grate and wind chambers; a longitudinal clapboard and a transverse clapboard, which forms the wind chamber with the grid shape are arranged on the lower side of the combustion device of the fire grate; separate bellows and air regulation mechanisms are arranged on each wind chamber. The admission regulator of fire grate has the advantages that the longitudinal clapboard and the transverse clapboard are arranged on the whole combustion surface of the fire grate, and the lower part of the surface of the fire grate is divided into a plurality of small wind chambers with the grid shape; the wind quantity can be singly adjusted by each small wind chamber, any part of the surface of the fire grate which has enough wind quantity can be ensured in the combustion process to satisfy the requirement of the wind quantity for fuel combustion; the fuel can be discharged after the fuel completely burns out. Thus, the combustion efficiency of the fuel can be greatly improved, and the energy source can be saved. The admission regulator of fire grate can be widely used for various boilers.
Description
(1) technical field:
The utility model relates to fire grate, especially the air distribution device of fire grate.
(2) background technology:
The grate firing stoker fired grate be a kind of be power with machinery, use solid-fuelled combustion apparatus, fuel is transported to stoker surface by certain thickness in the work, burns in the burner hearth of high temperature, by moving behind the forward direction, burns gradually simultaneously, waste residue is got rid of from the burner hearth afterbody.In order to guarantee that fuel burns fully, suitable air capacity be arranged and reasonably deliver in the fuel bed.The air distribution frame mode basically identical of at present domestic grate firing stoker fired grate, under the fire grate burner, longitudinally dividing plate is separated into several bar shaped air compartments, each bar shaped air compartment is provided with the air quantity governor motion, air directly enters air compartment from the fire grate one or both sides, is the fuel air feed by the fire grate slit, this air distribution mode, 2 weak points are arranged: the one, the blast inequality, just different by the air quantity of fire grate; The 2nd, air compartment can not be done the adjusting of horizontal air quantity, causes fuel combustion incomplete, and efficiency of combustion is low, energy waste.
(3) summary of the invention:
The purpose of this utility model provides a kind of fire grate air distribution adjusting device, and reasonable wind distribution guarantees that the stoker surface any part can both have sufficient air quantity, makes fuel completing combustion, improves efficiency of combustion, energy savings.
The technical scheme that the utility model is adopted for achieving the above object is: fire grate air distribution adjusting device, relate to fire grate and air compartment, longitudinal baffle and lateral partitions are set below the burner of fire grate, form the grid-shaped air compartment, each air compartment all is furnished with independently bellows and the air quantity governor motion is set.
Described grid-shaped air compartment is a sphere of movements for the elephants shape air compartment.
The utility model has the advantages that: on the whole burning surface of fire grate, be provided with longitudinal baffle and lateral partitions, the stoker surface lower part is divided into the little air compartment of plurality of grids shape, each little air compartment can be regulated air quantity separately, guaranteed that in combustion process the stoker surface any part can both have sufficient air quantity, satisfied the requirement of fuel combustion, made fuel burn the back fully and discharge air quantity, improve the efficiency of combustion of fuel greatly, saved the energy.
(4) description of drawings:
Fig. 1 is the utility model plane.
Fig. 2 is the utility model profile.
(5) specific embodiment:
Fire grate air distribution adjusting device as shown in Figure 1 and Figure 2, relate to fire grate and air compartment, longitudinal baffle 2 and lateral partitions 3 are set below the burner of fire grate 1, form sphere of movements for the elephants shape air compartment 5, each air compartment all has directly independently bellows 6, bellows 6 have air inlet 7 towards air compartment, and air quantity governor motion 4 is set.The fire grate lower part is divided into several little air compartments, and each air compartment can be regulated air quantity as required, and rational air quantity is provided, and can be widely used in various boilers.
Claims (2)
1, fire grate air distribution adjusting device, relate to fire grate and air compartment, it is characterized in that: longitudinal baffle (2) and lateral partitions (3) are set below the burner of fire grate (1), form grid-shaped air compartment (5), each air compartment all is furnished with independently bellows (6) and air quantity governor motion (4) is set.
2, fire grate air distribution adjusting device according to claim 1 is characterized in that: described grid-shaped air compartment (5) is a sphere of movements for the elephants shape air compartment.
