Abstract
The utility model relates to a vertical natural-ventilating coal-fired water-heating and heating boiler, which comprises a boiler inner liner, a boiler housing, a cooling discharge pipe, a base, a back combustion chamber and a front combustion chamber, wherein, combustion plates distributed with conical holes are arranged on a smoke and fire outlet of the front combustion chamber and in a back flue, and a combustion plate distributed with conical holes is installed blow the cooling discharge pipe. The utility model carries out secondary and triple combustion for black smoke and dusty smoke which come out of the combustion chambers so as to reduce the smoke and dust content to be discharged, and when the vertical natural-ventilating coal-fired water-heating and heating boiler runs, the utility model can achieve the requirement of the discharge standard of the national environmental protection without using a dust remover, and simultaneously enhances the heat efficiency of the vertical natural-ventilating coal-fired water-heating and heating boiler.
Description
The utility model relates to a kind of vertical fire coal hot-water heating boiler, and the boiler of furnace internal-lining, stove outer covering, furnace base, positive combustion chamber, anti-combustion chamber, cooling comb, rear pass and burner plate is especially arranged.
Existing vertical gravity-flow ventilation coal burning water heating heating boiler has furnace internal-lining, stove outer covering, furnace base, positive combustion chamber, anti-combustion chamber, cooling comb, in positive combustion chamber, back, anti-combustion chamber rear pass is arranged.Because burner plate itself and in stove arrangement limit, coal burns insufficient in boiler, causes the black smoke and the dust concentration height of discharge, is difficult to reach the index of national requirements for environmental protection.Also influenced simultaneously the thermal efficiency of boiler.
The purpose of this utility model is: overcome the deficiency of above-mentioned existing boiler, provide a kind of smoke medicining dust-removing effect good, the vertical gravity-flow ventilation coal burning water heating heating boiler that the thermal efficiency is high.
For achieving the above object, the utility model has been taked following technical measures: in the rear pass of anti-combustion chamber and positive back, combustion chamber, and the pyrotechnics exit of positive combustion chamber, the burner plate that is evenly equipped with conical bore is installed.Form the high temperature secondary furnace between the burner plate.
Following technical measures have also been taked: below the cooling comb, the burner plate that is evenly equipped with conical bore is installed, the uniform chamber of following formation hot blast of this burner plate.The district is provided with drifting dust dedusting door at the cooling comb, at the boiler top waste heat case is installed.
The utility model compared with prior art has following advantage:
After the burner plate that is evenly equipped with conical bore has been installed in the pyrotechnics exit of rear pass and positive combustion chamber, when unburnt black smoke and ash-laden gas are through the combustion plate in the positive combustion chamber, collision disperses to pass the conical bore on it, it is distinguished and admirable to make black smoke and ash-laden gas form rotation, this moment, burner plate self temperature was up to 1370 ℃, make black smoke and ash-laden gas reduction of speed, mixing in the high temperature secondary furnace, further burning through burner plate.After contained combustible carried out secondary or three burnings in the mixed flue gas, the flue dust major part of after-flame dropped in the following dust cleaning case, and all the other hot blasts enter the uniform chamber of hot blast.Because coal is burnt in above-mentioned combustion process more fully, thereby the fume amount of discharging is reduced.The utility model detects through the Tancheng County environmental monitoring station: blackness of exhaustion index stand Ge Mandu is less than 1 grade, and when coal was in normal combustion, smoke dust discharge concentration was 60.25mg/ mark m
3, smoke discharge amount is 0.534kg/h.When showing this boiler operatiopn, testing result just can reach the state environmental emissioning standard requirement without deduster.The improvement of said structure has improved fire box temperature (more than 1350 ℃) simultaneously, makes that coal catches fire soon, flame temperature is high, and to penetrate heat strong for the width of cloth in the burner hearth, and the thermal efficiency of boiler obviously improves.
After below the cooling comb above-mentioned burner plate being installed, make the hot blast in cooling comb district evenly rise good cooling effect.The district is provided with drifting dust dedusting door at the cooling comb, can improve the cooling-down effect of cooling comb.The boiler top can further absorb the waste heat that will discharge after the waste heat case is installed.Above measure all helps further improving the thermal efficiency of boiler.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the sketch of an embodiment of the present utility model.
Referring to Fig. 1.Furnace internal-lining 1, stove outer covering 2, cooling comb 3, base 7, anti-combustion chamber 5, positive combustion chamber 6 are arranged in the boiler.Among Fig. 1, burner plate 8 is installed in the pyrotechnics exit of positive combustion chamber, in the rear pass of anti-combustion chamber and positive back, combustion chamber, 2 road burner plates 10 and 13 is installed.Between the burner plate 8 and 10, form high temperature mixing secondary furnace 9 and 12 between 10 and 13 respectively.Below the cooling comb, burner plate 4 is installed.Form chamber, the uniform chamber of hot blast 4 between the burner plate 13 and 4.Be evenly equipped with conical bore 11 on the above-mentioned burner plate 8,10,13,4.
After coal was sent into anti-combustion chamber 5, the fire grate of falling positive combustion chamber 6 after the initiation combustion coking is carried out in anti-combustion chamber from the space that the pipe of bottom is arranged further burnt.Unburnt black smoke and ash-laden gas enter high temperature secondary furnace 9 through uniform conical bore on the burner plate 8 in the positive combustion chamber.High-temperature flue gas here reduction of speed, mixing suddenly carries out second-time burning, and flue dust separates, and then through burner plate 10, enters high temperature secondary furnace 12, repeats said process and carries out three burnings.Enter the uniform chamber 14 of hot blast through the hot blast after two, three burnings, the conical bore on burner plate 4 evenly leads to the cooling comb, and then upwards discharges.
The district is provided with drifting dust dedusting door 15 at the cooling comb, can remove the flue dust in cooling comb district, guarantees the comb cooling-down effect.Case 16 has surplus heat at the boiler top.After further absorbing its heat through the waste heat case, the hot blast in process cooling comb district discharges.
According to the kind of specification, model, payload and the coal of boiler, one burner plate can be installed reach result of use.
