A kind of preferred version as the utility model: described water-cooled grate is a fin type coiled pipe water-cooled grate, and the import of water-cooled grate links to each other with the backwater header, and the backwater header links to each other with water pump.
Another kind of preferred version as the utility model: the top of described upper smoke box is provided with removable cover.
The beneficial effect of the utility model: after 1, flue gas comes out from the primary zone, get into secondary combustion chamber, get into up smoke pipe again, get into descending smoke pipe afterwards again, flue gas flow is long, and exhaust gas temperature is low, has improved the thermal efficiency of boiler.
2, because up smoke pipe and descending smoke pipe all vertically are provided with, flue gas is gone up afterwards earlier, not dust stratification; And upper of furnace body is provided with smoke box, and removable cover is set on the smoke box, can conveniently clear up up smoke pipe and descending smoke pipe.
3, the high-temperature region is in upper boiler, and no grain slag precipitates, and avoids the tube sheet cracking of descending smoke pipe.
4, up smoke pipe is arranged in the interlayer of body of heater, can effectively utilize the area of fire grate, improves boiler output.
5, the water-cooled grate import links to each other with the backwater header, and the same water pump of backwater header (normal-pressure boiler is with the outer net backwater) links to each other, and adopts the forced circulation mode, has avoided in-tube fouling or grain slag deposition.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of interlayer connection place of water-cooled grate and body of heater.
In the accompanying drawing 1 be fire grate, 2 for secondary combustion chamber, 3 for coal feeding hole, 4 for the primary zone, 5 for chimney arch, 6 for the smoke evacuation chamber, 7 for body of heater, 8 for hydroecium, 9 for removable cover, 10 for upper smoke box, 11 for descending smoke pipe, 12 for delivery port, 13 for up smoke pipe, 14 for outlet flue, 15 for water-cooled grate, 16 for backwater header, 17 for interlayer.
The specific embodiment
The utility model comprises that set inside has the body of heater 7 of interlayer 17, is disposed with fire grate 1, water-cooled grate 15 and chimney arch 5 from the bottom to top in the body of heater 7; One end of water-cooled grate 15 links to each other with body of heater 7 outer backwater headers 16, and the other end of water-cooled grate 15 is communicated with the interlayer 17 of body of heater 7; Water-cooled grate 15 is with being primary zone 4 between the chimney arch 5, and 4 sides, primary zone are provided with coal feeding hole 3; Water-cooled grate 15 is with being secondary combustion chamber 2 between the fire grate 1, and the described chimney arch of its structural feature 5 tops are provided with the smoke evacuation chamber 6 with outlet flue 14, and smoke evacuation 6 tops, chamber are provided with the hydroecium 8 that is communicated with body of heater 7 interlayers 17, and side, hydroecium 8 top is provided with delivery port 12; Hydroecium 8 tops are provided with upper smoke box 10, are provided with the up smoke pipe 13 that is communicated with secondary combustion chamber 2 and upper smoke box 10 in the interlayer 17 of body of heater 7, are provided with the descending smoke pipe 11 that is communicated with upper smoke box 10 and smoke evacuation chamber 6 in the hydroecium 8.
A kind of preferred version as the utility model: described water-cooled grate 15 is a fin type coiled pipe water-cooled grate, and the import of water-cooled grate 15 links to each other with backwater header 16, and backwater header 16 links to each other with water pump.
