Abstract
The utility model provides an it generates carbon monoxide's device to ignite buggy in spout department which characterized in that the device includes: buggy pipe (1), the import of the buggy source of igniting (2), buggy (3), discharge (4), the buggy source of igniting (2) are located buggy pipe (1), and are in buggy pipe (1) center, are 300mm-500mm apart from discharge (4) distance.
Description
Technical field
The present invention relates to a kind of device of the coal dust generation carbon monoxide that ignites at nozzle, refer in particular to the application in the low nitrogen burning process of W burning type boiler.
Background technology
The nitrogen oxide produced in coal-fired power plant of current China running is one of principal element of atmosphere pollution, coal-fired plant boiler discharges a large amount of nitrogen oxide and further exacerbates environment deterioration, nitrogen oxide can form photochemical fog under certain condition and destroy atmospheric environment together with hydrocarbon on the one hand, serious harm human health, worsens the environment that the mankind depend on for existence; On the other hand, sulfur and nitrogen oxides is again the principal element forming acid rain. at present, there is large stretch of acid rain area all over the world. the development of China's acid rain is also rapidly abnormal, and serious acid precipitation and the fragile ecosystem make China's economy sustain losses severely.
Since the issuing and implementation of national standard " fossil-fuel power plant atmospheric pollutant emission standard ", the existing boiler NOX in many coal-burning power plants concentration of emission can not meet the limit value of new standard, and especially W burning type boiler NOX discharges even more serious.
Therefore, exploitation combustion with reduced pollutants technology or device, the discharge capacity reducing W burning type boiler nitrogen oxide is one of current matter of utmost importance urgently to be resolved hurrily.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of device of the coal dust generation carbon monoxide that ignites at nozzle, thus suppress and nitrogen oxides reduction.
For reaching above object, solution of the present invention is:
Generate the device of carbon monoxide at the nozzle coal dust that ignites, it is characterized in that this device comprises: coal pipe (1), coal dust ignition source (2), coal dust import (3), discharge (4); Coal dust ignition source (2) is positioned at coal pipe (1), and is in coal pipe (1) center, and distance discharge (4) distance is 300mm ~ 500mm.
Further, the effect of coal pipe (1) transports coal dust by air force, and coal dust is sent in coal pipe (1) by coal dust import (3), and quality of pc is 0.5kg/kg ~ 0.7kg/kg with the ratio of air quality.
Further, coal dust ignition source (2) is: a. fuel oil and pure oxygen premixed combustion produce; B. fuel oil and Combustion of Premixed produce; C. combustion gas and pure oxygen premixed combustion produce; D. combustion gas and Combustion of Premixed produce, and its effect is that the coal dust in coal pipe (1) is burnt in anaerobic environment, produces a large amount of carbon monoxide and sprays from discharge (4).
Principle of the present invention and feature are:
Coal dust enters in coal pipe and has in the air of speed and forms pulverized coal flow, whole pulverized coal flow is through the hot environment produced by fuel oil and pure oxygen premixed combustion or fuel oil and Combustion of Premixed or combustion gas and pure oxygen premixed combustion or combustion gas and Combustion of Premixed, make whole pulverized coal flow ignition, spray from discharge.
Because the quality of pc in coal pipe and the ratio of air quality are 0.5kg/kg ~ 0.7kg/kg, so the coal dust in coal pipe burns in the inner anaerobic environment of coal pipe, suppress and reduce the generation of nitrogen oxide, and create a large amount of carbon monoxide to spray from discharge, after a large amount of carbon monoxide generated enter burner hearth, suppress further and nitrogen oxide that in reduction burner hearth, coal dust firing produces.
accompanying drawing illustrates:
Fig. 1 is principle of the invention schematic diagram
detailed description of the invention:
As shown in Figure 1, a kind of device of the coal dust generation carbon monoxide that ignites at nozzle, device comprises: coal pipe (1), coal dust ignition source (2), coal dust import (3), discharge (4).
Coal dust enters in coal pipe (1) and has in the air of speed and forms pulverized coal flow, whole pulverized coal flow is through the hot environment produced by fuel oil and pure oxygen premixed combustion or fuel oil and Combustion of Premixed or combustion gas and pure oxygen premixed combustion or combustion gas and Combustion of Premixed, make whole pulverized coal flow ignition, spray from discharge (4).
To sum up characteristic feature of an invention is: because the quality of pc in coal pipe and the ratio of air quality are 0.5kg/kg ~ 0.7kg/kg, so the coal dust in coal pipe burns in the inner anaerobic environment of coal pipe, suppress and reduce the generation of nitrogen oxide, and create a large amount of carbon monoxide to spray from discharge, after a large amount of carbon monoxide generated enter burner hearth, suppress further and nitrogen oxide that in reduction burner hearth, coal dust firing produces.
Above enforcement; only to general description of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; anyone the various distortion made technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
