Therefore, the fuels can be thoroughly burnt, the thermal efficiency is higher, the dust particles in the discharged smoke are greatly reduced, and the utility model is beneficial to environmental protection, increases the carbonization burning speed of the main combustion zone and has high thermal efficiency.
Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of mobile gasification segmentation burning phase-splitting traveling-grate stoker environment-protection boiler.
Background technology
The not segmentation of burner hearth of existing boiler, fuel be the mixed phase burning in this burner hearth, causes the not thorough of fuel combustion, and thermal efficiency ratio is lower, and dust granule is many in the flue gas that boiler is got rid of, and is unfavorable for environmental protection.
The utility model content
The purpose of this utility model is in order to solve the not segmentation of burner hearth of above-mentioned existing boiler, fuel is the mixed phase burning in this burner hearth, cause the not thorough of fuel combustion, thermal efficiency ratio is lower, the many problems of dust granule in the flue gas that boiler is got rid of, and the thorough of a kind of fuel combustion is provided, thermal efficiency ratio is higher, the fewer mobile gasification segmentation burning phase-splitting traveling-grate stoker environment-protection boiler of dust granule in the flue gas that boiler is got rid of.
The utility model is by boiler body, traveling-grate stoker, furnace wall, coal bunker constitutes, be respectively arranged with preceding arch wall in the burner hearth of boiler from front to back, the first road partition wall, the second road partition wall, back arch wall, space between the preceding arch wall and the first road partition wall is the gasification, and combustion district, space between the first road partition wall and the second road partition wall is main combustion zone, space between the second road partition wall and the back arch wall is a burning-out zone, top is connected between gasification, and combustion district and the main combustion zone, the bottom is connected between main combustion zone and the burning-out zone, one side of burning-out zone is provided with overfire air device and mixed flow tracery wall, the traveling-grate stoker bottom is provided with wind apparatus one time, and this wind apparatus is by the required air zoning of carrying out in district.
Operation principle of the present utility model is: fuel enters from coal bunker, carry out gasification, and combustion through the gasification, and combustion district earlier, carry out carbon burning entering main combustion zone, after enter burning-out zone, the flame in gasification, and combustion district and hot flue gas enter main combustion zone from partition wall top, first road, the flame of main combustion zone and hot flue gas enter burning-out zone from partition wall bottom, second road, the complete afterburnt slag of fuel enters the grit chamber, hot flue gas enters the boiler convection heating surface, one side of burning-out zone is provided with overfire air device and mixed flow tracery wall, a wind apparatus of traveling-grate stoker bottom has been realized the mobile gasification and the segmentation burning phase-splitting of fuel by the required air zoning of carrying out in district.
The beneficial effects of the utility model are: fuel moves gasification and segmentation burning phase-splitting in boiler, fuel combustion thorough, and thermal efficiency ratio is higher; Because the flame in gasification, and combustion district and hot flue gas enter main combustion zone from partition wall top, first road, the flame of main combustion zone and hot flue gas enter burning-out zone from partition wall bottom, second road, make a large amount of the dropping on fire grate of dust granule in the flue gas, dust granule significantly reduces in the flue gas that boiler is got rid of, help environmental protection, and acceleration promotes main combustion zone carbonization burning velocity, thermal efficiency height.
