Abstract
A air distribution system in chain with fan shaped plate to make air even for boiler includes air chamber, fire grate and wind introducing pipe. According to structure and feature of the air chamber, the fan shaped plate to make air even and to be suitable to the air chamber will be designed and erected in different locations of the air chamber, but it will not knock against with dust collector set at bottom of the air chamber with its plane in vertical to direction of air flowing. The present invention can decrease air flow deviation along with width direction of the boiler a lot so as to decrease air amount of once a time for raising combustion temperature in the boiler and the boiler efficiency.
Description
Technical field:
The present invention relates to a kind of chain-grate boiler blowing system, relate in particular to a kind of chain-grate boiler blowing system, be applied to the grate firing chain-grate boiler, relate to fields such as chemical industry, the energy and light industry with fan-shaped homogenating plate.
Background technology:
Existing grate firing chain-grate boiler blowing system is by boiler both sides bellows, and the air compartment that the burning required air is introduced under the traveling-grate stoker leads to the storehouse air distribution.It is to regulate by each baffle plate of introducing the air channel that air quantity on the fire grate direction of motion is regulated.But moving on the perpendicular direction with fire grate because what adopt is logical storehouse air distribution, so air quantity does not have regulating measure on this direction, this will cause that this direction is given the inhomogeneous of air quantity on fire grate, the local air quantity that has is excessive, the some places deficiency in draught, thereby cause the imperfect combustion of fuel, make ash content carbon too high, reduced boiler efficiency.
Summary of the invention:
The objective of the invention is to defective, a kind of chain-grate boiler blowing system with fan-shaped homogenating plate is provided, reduce and move air quantity maldistribution phenomenon on the perpendicular direction of fire grate, the after-flame degree of fuel is improved greatly at existing boiler wind speed adjustment.
For realizing such purpose, the present invention designs the fan-shaped boiler homogenating plate that is fit to the wind storehouse in conjunction with the flow behavior of air in the air compartment, is installed in the wind storehouse, and the plane of homogenating plate is vertical with air-flow direction.
The design of fan-shaped homogenating plate will be according to the concrete size of boiler air compartment, can not brush up against mutually with the ash dropping hopper of air compartment bottom and not influence ash, fan-shaped homogenating plate can only install one additional, also can be at the diverse location welding polylith in wind storehouse, homogenating plate is in reinforcement place and air compartment welding, and the homogenating plate lee face is suitably strengthened.
In the wind storehouse of air under boiler both sides bellows level introducing fire grate, pass fire grate then vertically upward and combustion reaction also takes place with it through coal seam on the fire grate.
In the air intake of wind storehouse, because air quantity participates in burning on the way gradually, the streamwise air is fewer and feweri, air velocity reduces gradually, air-flow dilatation supercharging at the volley arrives the terminal static air pressure in wind storehouse and reaches maximum, because roughly suitable at the coal seam thickness and the resistance on air motion direction upper fire-grating top, so it is also many to pass chain fire-gate air quantity at wind storehouse end, this just causes inhomogeneous along air quantity flow on the air compartment depth direction.Do not wait along air compartment width wind speed in the whole wind storehouse in addition, air quantity also distributes inequality, and it is inhomogeneous to adopt fan-shaped homogenating plate can reduce the air quantity of wind storehouse on horizontal and vertical greatly.The design of fan-shaped homogenating plate among the present invention principle that air velocity equates when flowing through the homogenating plate section, in conjunction with the mobile numerical computations of air, when air-flow is flowed in air compartment, air velocity does not have too big variation substantially, thereby make the air-flow static pressure under the fire grate comparatively even, reach the effect that reduces flow deviation.
After using the present invention, can reduce greatly along the wind drift of boiler width direction.This volatile matter condition with higher less to coal powder size on the fire grate, that use coal effect that all improves significantly.Can reduce boiler primary air flow, raising stove internal combustion temperature after using the present invention, make coal combustion more abundant, prevent that fire grate is exposed, reduce boiler slag carbon content, improve boiler efficiency.
The drawing explanation:
Fig. 1 is a chain-grate boiler blowing system vertical profile structural representation of the present invention.
Among Fig. 1,1 refers to Chain Boiler Furnace Grate Made, and 2 expressions are from the blast pipe of bellows, and 3 represent the wind storehouses, and 4 is fan-shaped homogenating plate.
Fig. 2 is a chain-grate boiler blowing system plan structure schematic diagram of the present invention.
Among the figure, 2 expressions are from the blast pipe of bellows, and 3 expression wind storehouses add fan-shaped homogenating plate 4 in the wind storehouse.
The specific embodiment:
Below in conjunction with accompanying drawing technical scheme of the present invention is further described.
Chain-grate boiler blowing system structure of the present invention as shown in Figure 1 and Figure 2.The factors such as ash that consider, the cross section in wind storehouse 3 is up big and down small trapezoidal shape, installs fan-shaped homogenating plate 4 in wind storehouse 3 additional.Homogenating plate inserts in the wind storehouse, and its plane is vertical with air-flow direction, is welded in wind storehouse two walls, does not collide with the ash dropping hopper of air compartment bottom, can not influence ash.
Fan-shaped homogenating plate can adopt the thick sheet metal of 5mm that is.
The air that is used to burn enters wind storehouse 3 from blast pipe 2, in wind storehouse 3 through fire grate 1 pass on the fire grate the coal seam and with its burning.When air-flow flowed in air compartment, because the effect of damming of fan-shaped homogenating plate does not have substantially in air velocity under the situation of too big variation, the air-flow static pressure was comparatively even, reaches the effect that reduces flow deviation.
