Abstract
The utility model relates to a vertical coal smokeless burning boiler with good burning effect, and comprises a boiler main body, a boiler bladder, a burning chamber, an ash removal chamber, a primary air pipe, a main air pipe, a valve, a fan, an annular air chamber, a multi-layer annular nozzle and a radiation arch. The nozzle is composed of three layers to five layers. Each layer is provided with at least five nozzles. The outer layer of the nozzle is surrounded by the annular air chamber. The annular air chamber is connected with a blast pipe and the ash removing chamber is connected with another blast pipe. The two blast pipes join and interpenetrate outside the annular air chamber and then connect with the fan. The radiation arch is arranged at the upper side of the hearth. The utility model adopts a segmentation air distribution multi-grade burning design, and the thermal efficiency of the burning coal is greatly improved on the base of a traditional coal fired boiler. The effects of energy saving and environment protection are significant.
Description
A kind of vertical Coal-Fired Smokeless Combustion Boilers with good combustion effect.
Coal-burning boiler is extensive, a large amount of equipment that use in fields such as production, life.Because coal-burning boiler accounts for the overwhelming majority of whole productions, domestic boiler, so the quality of fired coal combustion effect is directly connected to the effect of energy resource consumption and environmental protection.
When vertical fire coal boiler combustion in the past is coal-fired, mainly by gravity-flow ventilation, for fire coal provides air.This boiler, combustion efficiency is relatively poor, and actual boiler thermal output is low.
The vertical fire coal boiler that has installs air blast additional outside the combustion chamber, though can improve combustion efficiency to a certain extent, unreasonable because of cloth wind, make the improvement of fired coal combustion effect be subjected to bigger restriction.
The purpose of this utility model is to make fire coal be able to abundant burning under the stirring of multilayer rotation wind by the conceptual design of a kind of segmentation cloth wind, multistage combustion, improves coal-fired efficiency of combustion, and energy savings fully satisfies environmental requirement.
The utility model is by boiler body, flue, the combustion chamber, dedusting chamber, an airduct, air main, valve, air blast, annular air compartment, multilayer annular nozzle and radiation arch are formed, nozzle is provided with 3 layers to 5 layers composition, every layer all on a horizontal plane, every layer is no less than 5 nozzles, be evenly distributed on boiler furnace around, nozzle on each aspect has an identical angle less than 40 ° with line entad respectively, the multilayer annular nozzle passes cylindrical shell and communicates with the combustion chamber, the nozzle skin is surrounded by an annular air compartment, annular air compartment and ajutage join, dedusting chamber and another ajutage join, article two, after ajutage is connected perforation outside annular air compartment, join with air blast, the radiation arch is arranged on the burner hearth top.Radiation arch is poured into a mould refractory cement outward by horizontal water tube and is formed, is arranged on above the burner hearth.
The course of work of the present utility model is as follows: when fired coal combustion, start the air blast air-supply, with the ajutage that annular air compartment joins wind is sent into annular air compartment, the wind that is full of annular air compartment and band certain pressure is blown into the combustion chamber by the multilayer nozzle that is periphery around the combustion chamber along the angle of setting, air in the combustion chamber divides the aspect rotation along multiple angles, simultaneously, with the ajutage that dedusting chamber joins wind is sent into dedusting chamber, and passing fire grate under the pressure of air-supply, to enter the combustion chamber up, air in the combustion chamber is under the promotion of multiple wind direction, form the high speed swirling eddy, fuel gas is fully burned, flying dust separates with flue gas, and flying dust is deposited in the burner hearth, thereby reaches dedusting, improve efficiency of combustion, energy-conservation and satisfy the purpose of environmental requirement.
The radiation arch has strengthened the radiation heat transfer in the stove, has improved fire box temperature, has changed the trend of flue gas, helps the sedimentation of flying dust in burner hearth.
Spoke the utility model makes it on the basis of traditional coal-burning boiler owing to adopted segmentation cloth wind multistage combustion design, has greatly improved the coal-fired thermal efficiency, and considerable energy saving, environment protecting are arranged, and promotion prospect and huge market potential are widely arranged.
Spoke Fig. 1 is a structural representation of the present utility model, also is that specification digest is with scheming; Fig. 2 is 1,2 layer of nozzle annular layout drawing; Fig. 3 is the 3rd a layer of nozzle annular layout drawing, and figure four is the 4th layer of nozzle ring layout drawing.Each label is respectively among the figure: 1 body of heater, 2 flues, 3 combustion chambers, 4 annular air compartment, 5 dedusting chamber, 6 nozzles, 7, valve, 8 air mains, 9 valves, 10 airducts, 11 air blasts, 12 radiation are encircleed.
Spoke is now lifted an example in conjunction with the accompanying drawings, and the utility model is described further.
Spoke embodiment: body of heater 1 height overall 3700mm, diameter 1216mm, flue 2 diameter 1000mm, the 5 high 200mm of dedusting chamber, the 4 high 500mm of annular air compartment, wide 100mm, sealing is centered around the outside of four layers of nozzle, first, two layers of nozzle entad are provided with 10, two-layer injector spacing is 50mm, second layer nozzle is apart from fire grate 350mm, and the 3rd layer of nozzle also is 10,30 ° of angle settings, apart from ground floor nozzle 200mm, the 4th layer of nozzle is 39 ° of settings of 6 angles, and apart from the 3rd layer of nozzle 100mm, nozzle is made of seamless steel pipe, diameter 10mm, pass body of heater and communicate with the combustion chamber, air main 8 diameter 100mm communicate with annular air compartment 4, and the centre is provided with the gate valve of 100mm, airduct 10 diameter 50mm, communicate with dedusting chamber 5, the centre is provided with the gate valve of 50mm, joins with air blast 11 after air main 8 and airduct 10 threeways are joined.
Spoke radiation spring base fire grate 800mm, 6 of horizontal water tubes, diameter 63mm, the thick 200mm of outer casting cement rear arch, round diameter 800mm.
