It is connected with dust-settling compartment 2, dust-settling compartment 2 is connected by exhaust gases passes 13 with the first lower smoke box 5, and the first lower smoke box 5 passes through the first backhaul
Smoke pipe 8 is connected to the second upper smoke box 4, and the second upper smoke box 4 is connected by the second backhaul smoke pipe 9 with the second lower smoke box 6, second time cigarette
Case 6 is connected by the 3rd backhaul smoke pipe 10 with the first upper smoke box 3, and the first upper smoke box 3 passes through under the 4th backhaul smoke pipe 11 and the 3rd
Smoke box 7 connects, and outlet flue 14 is provided with the 3rd lower smoke box 7, the auxiliary tobacco mouth 15 set on the second upper smoke box 4 is by pipeline and cigarette
Baffle plate 16 in gas converter 12 connects.
It is worth noting that, the described side wall of coal storeroom 1 is provided with air inlet 23, upper furnace door is additionally provided with coal storeroom 1
24th, lower furnace door 25, inspection hole 26, overfiren air port 27, flue gas mouth 28, breast hole 29, whole boiler sheet are provided with combustion chamber 17
The side wall of body is provided with delivery port 30.
In addition, described outlet flue 14 is connected with the import of air-introduced machine 31, the outlet of air-introduced machine 31, flue gas converter 12 are equal
It is connected to chimney 32.
Present embodiment is provided with A type water-cooled grates, and water-cooled grate is made into A fonts, changes common uphill furnace
The small feature of angle is arranged, the flow velocity of furnace grate tube reclaimed water on the basis of grate area is improved, can be improved, make endothermic effect more
It is good.
By the way of lower burning, moulded coal fuel is placed in top coal storeroom 1 boiler, using Action of Gravity Field, gradually under
Fall, into combustion chamber 17, with the burning of fuel, become ashes, because ashes volume diminishes, fuel continues to fall；Combustion chamber
17 are symmetrically set with curved water pipe 18, and combustion chamber 17 is additionally provided with header 19, A types fire grate connection upper collecting chamber 20, water-cooled grate
Pipe 21, A types fire grate connection lower header 22, curved water pipe 18 are connected upper collecting chamber 20, A types fire grate connection lower header with A type fire grates respectively
22 connections, while effective heat absorption, moreover it is possible to prevent fuel from entering in dust-settling compartment 2, and can ensures fuel even drop down；A type stoves
Row connects and water-cooled grate tube 21 is connected between upper collecting chamber 20 and A types fire grate connection lower header 22, the curved water pipe in combustion chamber 17
18th, header 19, A types fire grate connection upper collecting chamber 20, water-cooled grate tube 21, A types fire grate connect lower header 22 formed with Natural Circulation
System, it is ensured that heat distribution problem when combustion chamber high temperature burns, further improve efficiency of combustion.
The operation principle of present embodiment is：During normal combustion, the high-temperature flue gas after the burning of combustion chamber 17, enter first
Enter and depositing dust is carried out in dust-settling compartment 2, and the Secondary Air mixing after-flame entered with part by overfiren air port 27, the flue gas in afterburnt pass through
Exhaust gases passes 13 enter the first lower smoke box 5, then carry out heat release by the first backhaul smoke pipe 8, the second upper smoke box is entered after heat release
4, the heat release of the second backhaul smoke pipe 9 is entered back into by the second upper smoke box 4, after heat release, into the second lower smoke box 6, entered back into the 3rd time
The heat release of journey smoke pipe 10, after heat release, into the first upper smoke box 3, the heat release of the 4th backhaul smoke pipe 11 is entered by the first upper smoke box 3, finally
Into the 3rd lower smoke box 7, air-introduced machine 31 is entered by outlet flue 14 by the 3rd lower smoke box 7, air is discharged into by chimney 32.Due to
Air-introduced machine 31 can produce blast, and tiny structure can be produced in stove, be arranged on cigarette on the second upper smoke box 4, being connected with auxiliary tobacco mouth 15
Baffle plate 16 in gas converter 12 can close under suction function, flue gas can only spontaneous combustion room enter, by the cigarette after air-introduced machine 31
Chimney 32 is discharged；But when air-introduced machine 31 is stopped, because smoke pipe resistance is larger, the flue gas in combustion chamber 17 can not pass through four
The smoke pipe of backhaul discharges into chimney 32, and now the baffle plate 16 in flue gas converter 12 under gravity, automatically opens up, this
When, coal storeroom 1, combustion chamber 17, dust-settling compartment 2, exhaust gases passes 13, the first lower smoke box 5, the first backhaul smoke pipe 8, the second upper smoke box 4,
Auxiliary tobacco mouth 15, flue gas converter 12 just constitute common self-ventilation back firing boiler；It is anti-burn after caused flue gas then after heat release,
Discharged into chimney 32, because flue gas caused by anti-burn does not have dust and carbon black, and pass through smoke pipe heat release, environmental protection and energy saving.This
Outside, due to there is provided flue gas converter 12, ensure that the lasting progress in blowing out after-combustion, being truly realized fire-sealing time length.
Present embodiment changes general boiler and solves to solve completely because positive burn produces the emission problem of flue gas after blowing out
The disadvantage that blowing out of having determined is smoldered, the lasting progress of boiler shutdown after-combustion is ensure that, did not both pollute the environment, and will not also cause energy
Source wastes, energy-conserving and environment-protective, in addition to burning briquette, can also use bituminous coal, biomass fuel, before having wide market application
Scape.
