Abstract
Disclosed is a molded coal normal pressure inverse burning environmental protection boiler, relating to a middle-small size heating boiler. A water pipe and a grate are provided in a hearth; a secondary burning chamber is provided above the grate; a water pipe grate is provided on the secondary chamber; an independent burning chamber and a smoke channel are provided above the water pipe grate; the independent burning chamber is provided with a fire door. Compared with the same type boiler, the utility model has small volume and reasonable structure, adopts boiler inverse burning smoke returning technology, reduces smoke loss, avoids exhausting black smoke, succeeds in downward exchanging heat of smoke multi-travel, and deposits incomplete burning ash to the lower part of the boiler; the incomplete burning ash is exhausted by an ash discharging door, and thus smoke eliminating and dust removing without noise is implemented. The white smoke exhausted by the molded coal reaches to the environment protecting standard of state first class area. In addition, the utility model has convenient heating energy adjustable property, corrugated structure boiler wall and good structure performance, that is high mechanical strength and strong pressure resistance.
Description
(1) technical field:
The utility model relates to heating boiler, especially middle-size and small-size normal pressure heating boiler.
(2) background technology:
Owing to the environmental pollution reason, heating boiler has had significant improvement on the basis of conventional boiler at present, improve air inlet structure in the stove, enough air quantity are provided, fuel economy is improved, improve heat energy, but still come with some shortcomings problem, as complex structure, efficiency of combustion can further improve, and it is low relatively and smoke contamination is serious that flue gas directly discharges heat exchanger effectiveness.
(3) summary of the invention:
The purpose of this utility model is to solve above-mentioned not enough problem, provide a kind of rational in infrastructure, the thermal efficiency is high, effectively reduce the anti-environment-protection boiler that burns of moulded coal normal pressure of smoke contamination.
The technical scheme that the utility model is adopted for achieving the above object is: the anti-environment-protection boiler that burns of moulded coal normal pressure, water pipe and fire grate are housed in the burner hearth, secondary combustion chamber is arranged above fire grate, secondary combustion chamber is provided with the water pipe fire grate, water pipe fire grate top is independent combustion chamber and flue, and independent combustion chamber is provided with the door that makes a fire.
Described flue is a S type flue; The furnace wall is a corrugation shape; Shoot door is positioned at the horizontal wall surface top on the furnace wall.
The similar boiler with other of the utility model has been compared important breakthrough, small volume structure is reasonable, adopt boiler instead to burn back the cigarette technology, the fuel gas that produces in the independent combustion chamber burnouts being lighted by the coal seam high temperature combustion zone fully, after entering secondary combustion chamber downwards, discharge through flue again, emit heat energy, reduced flue gas loss, avoided the discharging black smoke, and anti-flue under the employing enlarged-area has been realized the downward multiple-pass heat exchange of flue gas, makes the grit of after-flame deposit to the body of heater bottom, discharge by the dust discharge door, thereby realize noiseless smoke abatement and dust control, flue gas is discharged " white cigarette " when using moulded coal, reaches national class area environmental requirement.Also have the performance of heat adjustment easily in addition, open the door that makes a fire greatly and promptly strengthen flame, an aperture that reduces to make a fire is that flame reduces.Corrugation shape structure is adopted in the furnace wall, and structural mechanical property is good, and promptly mechanical strength is big, and voltage endurance capability is strong.
(4) description of drawings:
Accompanying drawing is the utility model structural representation.
(5) specific embodiment:
The anti-environment-protection boiler that burns of moulded coal normal pressure as shown in drawings, water pipe 4 and fire grate 1 are housed in the burner hearth, secondary combustion chamber 11 is arranged above fire grate 1, secondary combustion chamber 11 is provided with water pipe fire grate 2, water pipe fire grate 2 tops are separated by independent combustion chamber sidewall 9 and upper wall 7, form independent combustion chamber 8 and S shape flue 5, door 10 makes a fire on the independent combustion chamber 8, wherein the fuel gas of Chan Shenging can not directly enter the flue discharge, burnouted but light by the coal seam high temperature combustion zone, enter secondary combustion chamber downwards after, discharge through S shape flue, realize anti-the burning, the thorough and environmental protection of burning.Furnace wall 3 is a corrugation shape, and shoot door 6 is positioned at the horizontal wall surface top on the furnace wall 3, small and exquisite and deashing convenience.
Claims (4)
1, the anti-environment-protection boiler that burns of moulded coal normal pressure, water pipe and fire grate are housed in the burner hearth, it is characterized in that: in fire grate (1) top secondary combustion chamber (11) is arranged, secondary combustion chamber (11) top is provided with water pipe fire grate (2), and water pipe fire grate (2) top is independent combustion chamber (8) and flue (5).
2, moulded coal normal pressure back firing boiler according to claim 1 is characterized in that: flue (5) is a S shape flue.
3, moulded coal normal pressure back firing boiler according to claim 1 and 2 is characterized in that: furnace wall (3) are corrugation shape.
