The specific embodiment
Purport of the present invention is: (1) utilizes wind-force that fuel is sent into burner hearth; (2) by regulating, can make fuel being more evenly distributed on the fire grate width; (3) cooling charging aperture.
Shown in Fig. 1 (a), by feeding inlet structure of the present invention will be crushed in the form of sheets, compression moulding biological mass-energy fuel (stalk) behind graininess or the powdery sends into boiler furnace, the antetheca 1 that it is arranged on described boiler furnace comprises top, bottom and governor motion.Angle when governor motion is used to control fuel and enters burner hearth.
Top is tilting fuel inlet structure, comprises a fuel inlet tube 2 that is provided with by predetermined angular with burner hearth antetheca 1 and a teat 3 of the expansion lateral outside below this fuel inlet tube 2.
The big I of the import of fuel inlet tube 2 is determined according to the Fuel Consumption of boiler.General fuel inlet tube 2 is fixed according to the flowability of different fuel with the angle of vertical plane, to guarantee that fuel falls to not stopping up naturally.
Referring to Fig. 2 (a)～(b), the bottom is the secondary air channel structure, comprises a secondary air channel 4 and the some secondary wind jet pipes 5 that insert in the described teat 3 that communicate with its pore that are fixed with on this secondary air channel 4.
The valve (not shown) of control air quantity is housed on the secondary air channel 4.The air quantity of secondary wind can be regulated by this valve.
Shown in Fig. 1 (a), governor motion comprise one be articulated in described teat 3 and be positioned at some secondary wind jet pipe 5 belows the cooling duct 6 that is used to cool off this governor motion, be welded on the controllable register 7 (referring to Fig. 3 (a)～(b)) on this cooling duct 6, and the described controllable register of a control 7 adjusting device of rotating.
