Abstract
The utility model provides a boiler double-feeding system for coal briquettes and other solid fuel. According to the boiler double-feeding system for coal briquettes and other solid fuel, the coal briquettes are burned at the lower layer of a fire grate, the other solid fuel is burned above the coal briquette layer, the burning zone of the fire grate is divided into two parts, the contact area between the fuel and oxygen is enlarged, the combustion efficiency is high, and the structure is simple. The boiler double-feeding system for the coal briquettes and the other solid fuel comprises a coal hopper and the fire grate, wherein the outlet of the coal hopper faces to the upper end face of the fire grate. The boiler double-feeding system is characterized in that a vertical plate from top to bottom is arranged at the middle of the coal hopper, the coal hopper is divided into a left side material cavity and a right side material cavity; a coal gate is mounted at the position, close to the vertical plate, of the lower part of the left side material cavity; the coal gate is capable of vertically moving; a coal gate plate is mounted in the upper cavity, far away from the vertical plate, of the right side material cavity; the coal gate plate is capable of vertically moving from top to bottom.
Description
Technical field
The utility model relates to the feeding structure technical field of boiler, is specially the two feeding systems of coal cinder and other solid-fuelled boilers.
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 coal cinder and the two feeding systems of other solid-fuelled boilers, its make lower floor that coal cinder is positioned at fire grate then, other solid fuels top of being positioned at coal cinder layer burns, it makes the burning zone of fire grate be divided into two parts, increased the contact area of fuel and oxygen, make efficiency of combustion high, and simple in structure.
The two feeding systems of coal cinder and other solid-fuelled boilers, 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, the bottom in material chamber, described left side is provided with coal gate near the position of riser, the upper and lower movement in vertical direction of described coal gate is arranged, in the upper cavity away from riser in material chamber, described right side, coal flashboard is installed, described coal flashboard from top to bottom movement in vertical direction is arranged, the position that keeps left, the below of described coal flashboard is provided with level to the cylinder of arranging, the upper left side of described cylinder is furnished with transverse baffle, described baffle plate is positioned at the right side of described riser, by connecting plate assembly, be anchored on described riser, advance from left to right in the upper surface of described fire grate.
It is further characterized in that: the top of described coal gate is connected with air cylinder driven structure.
Adopt after the utility model, coal cinder enters into the left side of fire grate upper surface from material chamber, left side, wherein the upper and lower movement in vertical direction of coal gate is controlled the height layer forming between left side coal cinder and fire grate upper surface, it blocks unnecessary coal cinder and advances to the right together along fire grate, and now coal cinder layer is close to the upper surface of fire grate and is advanced to the right together; Other solid fuels comprise that coal dust, biomass fuel enter into the right side of fire grate upper surface from material chamber, right side, be covered on the coal cinder layer having formed, under other solid fuels, fall behind the position that can effectively control its whereabouts by baffle plate, the cylinder that process is being rotated loosens and fire grate is sent in transmission, thereby the gap that its inlet amount is formed between itself and cylinder by the upper and lower movement in vertical direction of coal flashboard regulates, solid fuel after cylinder loosens its dispersed placement on coal cinder layer; It makes coal cinder be positioned at the lower floor of fire grate, burn in the top that other solid fuels are positioned at coal cinder layer, it makes the burning zone of fire grate be divided into two parts, because solid fuel dispersion is arranged on coal cinder 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 is divided into material chamber 4, left side, material chamber, right side 5, the bottom in material chamber 4, left side is provided with coal gate 6 near the position of riser 3, coal gate is movement in vertical direction layout Shang Xia 6, and the top of coal gate 6 is connected with air cylinder driven structure 7.In the upper cavity away from riser 3 in material chamber, right side 5, coal flashboard 8 is installed, coal flashboard 8 from top to bottom movement in vertical direction is arranged, the position that keeps left, the below of coal flashboard 8 is provided with level to the cylinder 9 of arranging, the upper left side lateral arrangement of cylinder 9 has baffle plate 10, baffle plate 10 be positioned at riser 3 right side, by connecting plate assembly 11, be anchored on riser 3, advance from left to right in the upper surface of fire grate 2.
