Description
Technical field
The utility model belongs to boiler manfacturing technical field, specifically, particularly relates to a kind of scoot burning boiler.
Background technology
In China, Small And Medium Capacity boiler fuel used large be main mainly with coal, oil, gas, in recent years along with China's expanding economy and opening, some wood processing enterprises of the country in Southeast Asia such as Indonesia, Malaysia and domestic wood-processing industry development are rapidly, these enterprises usually produce a large amount of wood wastes, when the holding at high price of bunker coal, most enterprise all using these wood wastes as boiler oil burning with produce steam for the production of.But current scoot boiler is all formed by coal-fired boiler reform, mainly there is following defect in it: 1, because scoot is high-moisture, high volatile fuel, the air distribution etc. of the combustion space of conventional boiler, shape, boiler does not mate with the combustion characteristics of scoot, cause that boiler combustion is unstable, efficiency of combustion and the thermal efficiency low; 2, scoot is easily put up a bridge, is united, and makes feed in stove uneven, causes fire grate seriously impaired; 3, exhaust emissions is not up to standard, seriously polluted.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides that a kind of efficiency of combustion is high, fire grate long service life and the scoot burning boiler of energy-conserving and environment-protective more.
Described scoot burning boiler, comprises the burning boiler of pressure-bearing type, and burning boiler front end is provided with feed arrangement, and rear is provided with back-end surfaces; In burning boiler, surrounding is provided with water-cooling wall, bottom is provided with three grades of reciprocal grates driven, air compartment is provided with bottom reciprocal grate, the top of burning boiler is provided with large of top, large of described top comprises lower drum, convection bank heating surface and superheater, and convection bank heating surface, superheater and water-cooling wall are connected with upper lower drum respectively; It is highly the face arch of 7m-8m and the rear arch of low long structure that burner hearth adopts, and face arch and rear arch are respectively equipped with secondary air system.
Downward-sloping 15 °-20 ° of described reciprocal grate.
Swinging convection bank is provided with between superheater and upper lower drum.
Described back-end surfaces adopts steel pipe type economizer and steel tubular air heater.
Compared with prior art, the beneficial effects of the utility model are:
1, efficiency of combustion is high.According to the combustion characteristics of scoot, adopt higher burner hearth face arch and the rear arch of low long structure, and be provided with secondary air system at rear arch, make from rear arch high-temperature flue gas out, to wash away in the horizontal velocity of about 7 meters per second forward arch area, give face arch district by amount of heat band, enhance the heat radiation to fuel bed, ensure that burning of fuel; The flue gas that front and back encircle out mixes strongly, increases the time of staying of flue gas in burner hearth, is conducive to the burning cmpletely of fuel.
2, adopt three grades of drivings and downward-sloping reciprocal grate, decrease the time of staying of scoot in course of conveying, to reduce the possibility that scoot is put up a bridge, united, extend the working life of reciprocal grate, reduce maintenance load.
3, energy-conserving and environment-protective more.The combustion characteristics of structure of the present utility model and scoot adapts, sufficient combustion, and scoot ash after incineration is low, can minimizing to greatest extent, effectively reduces ash discharge and the pollution to water source, soil, makes tail gas to reach discharge standard.Secondly, the combustion technology of scoot not only saves coal resources, and reduces NOx, SO
2and CO
2discharge Deng dusty gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, feed arrangement; 2, secondary air system; 3, convection bank heating surface; 4, primary superheater; 5, swinging convection bank; 6, two-stage superheater; 7, upper lower drum; 8, economizer; 9, air preheater; 10, ash dropped unit A; 11, cigarette air channel; 12, ash dropped unit B; 13, mucking machine; 14, rear arch; 15, reciprocal grate; 16, air compartment; 17, face arch.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, scoot burning boiler comprises the burning boiler of pressure-bearing type, and burning boiler front end is provided with feed arrangement 1, and rear is provided with steel pipe type economizer 8 and steel tubular air heater 9; In burning boiler, surrounding is provided with water-cooling wall, bottom is provided with three grades of reciprocal grates 15 driven, air compartment 16 is provided with bottom reciprocal grate 15, the top of burning boiler is provided with large of top, large of described top comprises lower drum 7, convection bank heating surface 3 and superheater, be provided with swinging convection bank 5 between superheater and upper lower drum 7, convection bank heating surface 3, superheater and water-cooling wall are connected with upper lower drum 7 respectively; It is highly the face arch 17 of 7m-8m and the rear arch 14 of low long structure that burner hearth adopts, and face arch 17 and rear arch 14 are respectively equipped with secondary air system 2; Downward-sloping 15 °-20 ° of described reciprocal grate 15.
Described superheater comprises primary superheater 4 and two-stage superheater 6, and the height of burner hearth face arch 17 is 7.5m, downward-sloping 15 ° of reciprocal grate 15.
The utility model operationally, scoot is delivered on reciprocal grate 15 by feed arrangement 1, in reciprocal grate 15 front end through the dry after-combustion of the hot air of air compartment 16, scoot moves from front to back under the driving of reciprocal grate 15, thus completes whole burning process.Scoot is constantly promoted by reciprocal grate 15, is overturn, and is burnt completely under the Cocktail DNA vaccines of the secondary air system 2 arranged in the First air and burner hearth of air compartment 16; The high-temperature flue gas that burning produces is after water-cooling wall heat exchange in burner hearth, successively through convection bank heating surface 3, primary superheater 4, two-stage superheater 6 and swinging convection bank 5, steel pipe type economizer 8 and steel tubular air heater 9 be fully heat exchange again, the low-temperature flue gas of final generation by cigarette air channel 11, is sent into chimney by air-introduced machine and is entered air after cleaner.
Dust in flue gas is discharged through ash dropped unit A10 and ash dropped unit B12, and the lime-ash that burning produces is discharged by mucking machine 13.
