Abstract
The utility model discloses a kind of environment-friendly type vertical fire coal boiler, take the underfeed firing device, and be provided with screw stoker, make fire coal send into burner hearth from bottom to top equably, form burning from top to bottom, while is at the upside of boiler combustion layer, be provided with the secondary air device, make the further mixed combustion of fuel gas and air, the flow process of prolong smoke and flying dust changes the full level of air-flow to burner hearth, in burner hearth, form the secondary air curtain, pin the fly ash particle in the flue gas, thereby not only improved the efficiency of combustion of boiler effectively, and alleviated the pollution of coal-burning boiler greatly atmosphere.
Description
One, technical field
The utility model relates to a kind of coal-burning boiler, belongs to boiler manufacturing technology field.
Two, background technology
Existing vertical fire coal boiler adopts usually and advances the coal mode by hand, and this craft is advanced the vertical fire coal boiler of coal mode because coal is periodically to throw on the coal seam of burning from fire door, and its combustion process is tool periodicity also.After throwing coal, the fugitive constituent of coal is separated out, and the burning required air quantity is more, and after this fugitive constituent slowly decomposes and finishes, and needed air reduces gradually.But the amount of supplied air in the boiler is constant substantially in coal combustion process.Therefore, lack of air in throwing the coal rear hearth, incomplete combustion, chimney a large amount of black smoke of emerging causes serious environmental to pollute.In addition, because incomplete combustion has not only caused a large amount of burning caloic losses, and has wasted valuable energy resources.
Three, summary of the invention
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of rational in infrastructure, sufficient combustion, thermal efficiency height, and can alleviate the environment-friendly type vertical fire coal boiler of fireman's intensity on International Labour Day significantly.
For achieving the above object, the utility model has been taked following technical measures:
Environment-friendly type vertical fire coal boiler described in the utility model is taked the underfeed firing device, and be provided with screw stoker, make fire coal send into burner hearth from bottom to top equably, form burning from top to bottom, while is at the upside of boiler combustion layer, be provided with the secondary air device, make the further mixed combustion of fuel gas and air, the flow process of prolong smoke and flying dust, change the full level of air-flow, in burner hearth, form the secondary air curtain, pin the fly ash particle in the flue gas burner hearth, thereby not only improved the efficiency of combustion of boiler effectively, and alleviated the pollution of coal-burning boiler greatly atmosphere.

Fig. 1 is a structural representation of the present utility model
Wherein: 1-shell end socket 2-shell 3-base 4-impact tube 5-burner hearth top 6-burner hearth 7-smoke pipe 8-smoke baffle plate 9-horizontal water tube 10-fire grate 11-Power Drive Unit 12-adds coal hopper 13-auger conveyor 14-blower fan 15-secondary wind inleting tube 16-volume adjusting apparatus 17-secondary air mouth
Five, the specific embodiment
Environment-friendly type vertical fire coal boiler comprises shell end socket 1, shell 2 and base 3 three parts, in shell 2, is provided with impact tube 4, burner hearth top 5, burner hearth 6 and smoke pipe 7; In burner hearth 6, be provided with horizontal water tube 9; Between burner hearth 6 and base 3, be provided with fire grate 10.
Outside vertical fire coal boiler foundation 3, be provided with screw stoker structure and secondary air device.The screw stoker structure by Power Drive Unit 11, add coal hopper 12 and auger conveyor 13 constitutes, auger conveyor 13 is arranged at the below of fire grate 10, constitutes the underfeed firing device.During burning, coal-fired from bottom to top the ground warp fire grate is sent in the burner hearth by the below of auger conveyor 13 from fire grate 10, forms top-down lower feeding reverse burning machine reason, has guaranteed that fire coal burns fully.
The secondary air device is made of blower fan 14, secondary wind inleting tube 15 and 17 in secondary air mouth, and secondary air mouth 17 is higher than the upside of burner hearth burning zone; It can make fuel gas and the further mixed combustion of air in the burner hearth, and the flow process of prolong smoke and flying dust changes the full level of air-flow to burner hearth, forms secondary general mood curtain in burner hearth, pins the fly ash particle in the flue gas, improves the efficiency of combustion of boiler.
In order to make boiler adapt to the fire coal of different caloics, and guarantee that it fully burns, on secondary wind inleting tube 15, also be provided with volume adjusting apparatus 16.Volume adjusting apparatus 16 can be regulated arbitrarily the secondary air amount of the fire coal of different caloics.
In addition, at the middle part of burner hearth, also be provided with dividing plate 8, it can filter the fly ash particle in the flue gas effectively, further environment purification.
