Abstract
The invention relates to an apparatus and method for generating carbon monoxide through igniting coal dust at a nozzle. The apparatus comprises a coal dust tube (1), a coal dust igniting source (2), a coal dust inlet (3) and a coal dust outlet (4).
Description
Technical field
The present invention relates to the device and method of a kind of coal dust generation carbon monoxide that ignites at nozzle, refer in particular to the application during the low nitrogen burning of W burning type boiler.
Background technology
The nitrogen oxides produced in coal-fired power plant of current China running is one of principal element of atmospheric pollution, coal-fired plant boiler discharges substantial amounts of nitrogen oxides and further exacerbates ecological deterioration, on the one hand nitrogen oxides can form photochemical fog under certain condition together with Hydrocarbon and destroy atmospheric environment, serious harm human health, deteriorates 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. and the development of China's acid rain is also abnormal rapid, and serious acid precipitation and 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 ", many coal-burning power plants existing boiler DS NOx Est concentration can not meet the limit value of new standard, and especially W burning type boiler DS NOx Est is even more serious.
Therefore, exploitation combustion with reduced pollutants technology or device, the discharge capacity reducing W burning type boiler nitrogen oxides is one of matter of utmost importance the most urgently to be resolved hurrily.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide the device and method of a kind of coal dust generation carbon monoxide that ignites at nozzle, thus suppress and nitrogen oxides reduction.
For reaching object above, the solution of the present invention is:
The device and method of a kind of coal dust generation carbon monoxide that ignites at nozzle, it is characterised in that this device includes: coal pipe (1), coal dust ignition source (2), coal dust import (3), discharge (4).
Further, use and there is the air of certain speed coal dust is sent into coal pipe (1) from coal dust import (3), coal dust ignition source (2) ignite the coal dust in coal pipe (1), spray from discharge (4) after whole coal powder ignitions.
Further, the quality of pc in coal pipe (1) is 0.5kg/kg ~ 0.7kg/kg with the ratio of air quality, makes the coal dust in coal pipe (1) burn in anaerobic environment, produces substantial amounts of carbon monoxide and sprays from discharge (4).
Further, coal dust ignition source (2) is positioned at coal pipe (1), and its energy of igniting comes from: a. fuel oil produces with pure oxygen premixed combustion；B. fuel oil produces with Combustion of Premixed；C. combustion gas produces with pure oxygen premixed combustion；D. combustion gas produces with Combustion of Premixed, and the high temp fire core that coal dust ignition source (2) produces makes the coal dust in coal pipe (1) be sprayed by discharge (4) after being in the state of catching fire.
Further, the distance of coal dust ignition source (2) distance discharge (4) is 300mm ~ 500mm.
Principle and the feature of the present invention are:
Coal dust enters in coal pipe and forms pulverized coal flow with having in the air of speed, all pulverized coal flow is through the hot environment produced with Combustion of Premixed with pure oxygen premixed combustion or combustion gas with Combustion of Premixed or combustion gas with pure oxygen premixed combustion or fuel oil by fuel oil, make whole pulverized coal flow ignition, spray from discharge.
Owing to the ratio of the quality of pc in coal pipe with air quality is 0.5kg/kg ~ 0.7kg/kg, so the coal dust in coal pipe is to burn in the internal anaerobic environment of coal pipe, suppress and reduce the generation of nitrogen oxides, and create substantial amounts of carbon monoxide to spray from discharge, after a large amount of carbon monoxides generated enter burner hearth, the nitrogen oxides that in further suppression and 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 it is shown in figure 1, the device and method of a kind of coal dust generation carbon monoxide that ignites at nozzle, device includes: coal pipe (1), coal dust ignition source (2), coal dust import (3), discharge (4).
Coal dust enters in coal pipe (1) and forms pulverized coal flow with having in the air of speed, all pulverized coal flow is through the hot environment produced with Combustion of Premixed with pure oxygen premixed combustion or combustion gas with Combustion of Premixed or combustion gas with pure oxygen premixed combustion or fuel oil by fuel oil, make whole pulverized coal flow ignition, spray from discharge (4).
The feature to sum up invented is: owing to the ratio of the quality of pc in coal pipe with air quality is 0.5kg/kg ~ 0.7kg/kg, so the coal dust in coal pipe is to burn in the internal anaerobic environment of coal pipe, suppress and reduce the generation of nitrogen oxides, and create substantial amounts of carbon monoxide to spray from discharge, after a large amount of carbon monoxides generated enter burner hearth, the nitrogen oxides that in further suppression and reduction burner hearth, coal dust firing produces.
Above enforcement; it it is only the general description to the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; anyone the various deformation making technical scheme and improvement, all should fall in the protection domain that claims of the present invention determines.
