In the present invention, main burner 1 is also fitted with wind powder and supplements pipeline 11, and it is bend pipe that wind powder supplements pipeline 11 end, and outlet is placed in the middle part of main burner 1 primary air piping, for supplementing wind and coal dust in main burner 1.
The diameter in wind powder pipe road, front end 2 should not exceed the radius of main burner 1 First air pipeline, and it gets wind powder mixture from the outside of main burner First air tube bends.Flow control baffle plate 3 is circular.Current equalizer about 4 section be diametrically little under the circle that very much not waits.Pyrolysis chamber 5 is ellipsoid shape, and in order to make the abundant pyrolysis of coal and consider the factor of gas expansion, its width is greater than the radius in wind powder pipe road, front end.Gas-jet 13 and coal dust shower nozzle 14 can swing up and down.
The course of work of the present invention is as follows: as shown in Figure 1, an air-vent 17 is opened at the middle part of the horizontal flue 16 of boiler, and make it and draw smoke pipeline 15 and be connected, draw smoke pipeline 15 other end and be connected with the throat of de Laval noz(zle) 6, the high-temperature flue gas of drawing from burner hearth horizontal flue 16 in order to conveying.Pressure fan 7 is connected to the entrance of de Laval noz(zle) 6, and 300 DEG C of hot-airs are sent in de Laval noz(zle) 6, hot-air pressure in de Laval noz(zle) 6 flow process reduces, speed raises, thus cause the throat pressure of de Laval noz(zle) 6 lower, drawing smoke pipeline 15 utilizes Involving velocity to extract in feeding de Laval noz(zle) 6 by the heat smoke in boiler horizontal gas pass, the heat smoke and hot-air that enter de Laval noz(zle) 6 are sent in pyrolysis of coal room 5, for pulverized coal pyrolysis provides thermal source by air supply duct 8.
As shown in Figure 2, First air carries coal dust and enters wind powder pipe road, front end 2, then pyrolysis of coal room 5 is entered after flowing through flow control baffle plate 3 and current equalizer 4, utilize the heat that the heat smoke from boiler horizontal gas pass provides, coal dust pyrolysis in pyrolysis of coal room 5, coal gas air-coal separating in afterbody pipeline 9 that pyrolysis produces, based on coal gas inside bend pipe, then based on the solid particle after remaining coal dust and pyrolysis outside bend pipe, the dividing plate 12 of bend pipe afterbody maintains this air-coal separating effect.The pyrolysis gas flowing through back-end ductwork 9 is divided into two strands of air-flows by dividing plate 12, that is: rich gas stream and depleted gas stream.Rich gas stream enters gas-jet 13, and depleted gas stream enters the separate adjustable direction of 14, two, coal dust shower nozzle.Upwards, when coal dust shower nozzle 14 is downward, rich gas stream can hold up the coal dust of main burner ejection to adjustment gas-jet 13, for coal powder ignition provides effective thermal source, makes bias combustion occur due effect.
For different operating mode, need the generation adjusting pyrolysis coal gas.The mixture flow rate entering pyrolysis chamber can be effectively controlled by the aperture of adjustment flow control baffle plate 3.By adjusting the power of pressure fan 7, the flow entering de Laval noz(zle) 6 and pyrolysis of coal room 5 heat smoke and hot-air can be changed, thus control the degree of pyrolysis of coal, meet the requirement of thermal power plant's different load thus.
Boiler, when normally running, has a baffle plate in the porch of drawing smoke pipeline 15, pressure fan 7 does not work simultaneously, and now the heat smoke of horizontal flue can not flow in de Laval noz(zle) 6 through drawing smoke pipeline 15, and pyrolysis and combustion device does not work; When unit is in underrun, open baffle plate, pressure fan 7 sends into the hot-air of 300 DEG C simultaneously, and the thermal plume of horizontal flue flows in de Laval noz(zle) 6 through drawing smoke pipeline 15, and for the pyrolysis of coal dust provides heat, pyrolysis and combustion device normally works.Before de Laval noz(zle) 6 throat, in pipe, gas temperature is about 300 DEG C, and after throat, the interior mixture temperature of pipe is between 800-900 DEG C.
When performing low-load running of machine set or boiler cold and hot state start, replace the part of unit to throw oil with pyrolysis and combustion device, burning when stabilizing underload in stove, improves unit operation economy and security.
The above embodiment of the present invention is not limiting the scope of the present invention; embodiments of the present invention are not limited thereto; according to foregoing of the present invention; according to ordinary technical knowledge and the customary means of this area; do not departing under the present invention's above-mentioned basic fundamental thought prerequisite; to the amendment of other various ways that said structure of the present invention is made, replacement or change, all drop within protection scope of the present invention.
