Abstract
The utility model provides a double-fuel feeding device which is used for respectively upward and downward arranging two kinds of fuel on an upper surface of a fire grate, dividing a combustion layer of the fire grate into two parts, increasing contact areas between the two kinds of fuel and oxygen and increasing the combustion efficiency. The double-fuel feeding device has a simple structure and comprises a coal scuttle and the fire grate, wherein an outlet of the coal scuttle is faced to an upper end face of the fire grate; the double-fuel feeding device is characterized in that a vertical plate from top to bottom is arranged on the middle part of the coal scuttle and is used for dividing the coal scuttle into a left material cavity and a right material cavity; coal flashboards are respectively arranged in the upper cavities of the left material cavity and the right material cavity; the coal flashboards are moveably arranged from top to bottom along a vertical direction; a roller which is distributed along a horizontal direction is arranged in a left-keeping position under the two coal flashboards; a horizontal baffle is arranged above the left side of the roller; a layering screen cloth is arranged in the position of the vertical plate on the lower part of the left material cavity; and the layering screen cloth is obliquely downward arranged.
Description
Technical field
The utility model relates to the feeding structure technical field of boiler, is specially double fuel feeding device.
Background technology
Be accompanied by the development of energy industry, the simple burning coal of existing boiler can not be met the need of market, therefore produced two feed boilers, the feeding structure of existing pair of feed boiler is all independently arranged separately, its complex structure, need to change the global design of boiler, and the defect such as the undercapacity, the efficiency of combustion that exist during fuel in same chain-grate boiler are low, over-emitting black exhaust.
Summary of the invention
For the problems referred to above, the utility model provides double fuel feeding device, and it makes two kinds of fuel upper and lower upper surface that is arranged in fire grate respectively, it makes the burning zone of fire grate be divided into two parts, increase the contact area of fuel and oxygen, made efficiency of combustion high, and simple in structure.
Double fuel feeding device, its technical scheme is such: it comprises coal bunker, fire grate, the outlet of described coal bunker is towards the upper surface of described fire grate, it is characterized in that: the middle part of described coal bunker is provided with top-down riser, described coal bunker is divided into material chamber, left side, material chamber, right side, material chamber, described left side, coal flashboard is all installed in the upper cavity in material chamber, right side separately, described coal flashboard from top to bottom movement in vertical direction is arranged, the position that keeps left, the below of two described coal flashboards is provided with level to the cylinder of arranging, the top, left side of described cylinder is furnished with transverse baffle, the position of the riser of the bottom in material chamber, described left side is provided with layering screen cloth, the oblique lower layout of described layering screen cloth, the lower bevel of described layering screen cloth is towards the upper surface, left side of described fire grate, advance from left to right in the upper surface of described fire grate.
Adopt after the utility model, bituminous coal is fallen to the position of baffle plate by the material chamber, left side of coal bunker, baffle plate bituminous coal is loosened through the cylinder that rotating and transmission to fall layering screen online, by the choosing of layering screen mesh screen, from the lower bevel layering of layering screen cloth, fall into the upper surface, left side of fire grate afterwards, form bituminous coal layer, advance from left to right with bituminous coal layer in the upper surface of fire grate, the inlet amount of bituminous coal can regulate by the coal flashboard on top, material chamber, left side; Biomass fuel can be fallen to by the material chamber, right side of coal bunker the position of baffle plate, the cylinder that baffle plate is crossed biomass fuel and rotated loosens and transmits, send into upper strata on the bituminous coal layer of fire grate upper surface, burn, wherein the inlet amount of biomass fuel can regulate by the coal flashboard on Liao Qiang top, right side; To sum up, biomass fuel after cylinder loosens its dispersed placement on bituminous coal layer; Burn in the top that its lower floor, biomass fuel that makes bituminous coal layer be positioned at fire grate is positioned at coal cinder layer, it makes the burning zone of fire grate be divided into two parts, because biomass fuel dispersed placement is on bituminous coal layer, increased the contact area of fuel and oxygen, make efficiency of combustion high, and only need a coal bunker to be divided into two charging cavitys, it is simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises coal bunker 1, fire grate 2, the outlet of coal bunker 1 is towards the upper surface of fire grate 2, the middle part of coal bunker 1 is provided with top-down riser 3, coal bunker 1 is divided into material chamber 4, left side, material chamber, right side 5, material chamber 4, left side, in the upper cavity in material chamber, right side 5, be separately installed with left side coal flashboard 6, right side coal flashboard 10, left side coal flashboard 6, right side coal flashboard 10 all from top to bottom movement in vertical direction arrange, left side coal flashboard 6, the position that keeps left, the below of right side coal flashboard 10 is respectively arranged with level to the left side cylinder 7 of arranging, right side cylinder 11, left side cylinder 7, the top, left side of right side cylinder 11 is furnished with respectively left side transverse baffle 8, right side transverse baffle 12, the position of the riser 3 of the bottom in material chamber 4, left side is provided with layering screen cloth 9, the oblique lower layout of layering screen cloth 9, the lower bevel of layering screen cloth 9 is towards the upper surface, left side of fire grate 2, advance from left to right in the upper surface of fire grate 2.
