Abstract
The invention provides a methane boiler which can ensure stable fire-catching state of methane and full combustion and no waste of the methane. The methane boiler comprises a steel frame, a hearth, a steam drum and a water drum, wherein the hearth is arranged on the steel frame, a horizontal flue above the hearth is internally provided with a high-temperature overheater and a low-temperature overheater, the steam drum is connected with the water drum through a convection bank, and a tail flue is internally provided with a coal economizer and an air preheater. The methane boiler is characterized in that a methane combustor is arranged on a front wall of the hearth horizontally and comprises a methane circular pipe, a methane inlet, methane outlets and a guide blade, the methane outlet is exposed of the hearth and communicated with the methane circular pipe, the methane outlets are through holes uniformly distributed on the external circumferential surface of the methane circular pipe, and the guide blade is welded on the outer circumferential surface of the methane circular pipe, and positioned in the methane flowing direction of the through holes.
Description
Technical field
The present invention relates to the technical field of structures of boiler, be specially methane boiler.
Background technology
The boiler of China is main fuel with the coal at present, and sulfur dioxide and flue dust in its combustion product enter atmosphere, are the major polluting sources of causing atmosphere pollution.Therefore, the adjustment energy consumption structure progressively improves the ratio of using liquids and gases fuel, particularly uses reproducible biogas, and reduce and pollute, be one of measure of strengthen environmental protection.Biogas be various organic substances (animals and plants remains, human and animal excreta, municipal refuse and industrial wastewater etc.) at secluding air, a kind of imflammable gas that produces through the fermentation of microorganism and is arranged under suitable temperature, the damp condition.Because the raw material sources of biogas are extensive, cheap, calorific value is higher, is again the byproduct when debirs are handled in solid and the liquid, helps environmental protection, thus be a kind of gaseous fuel of high-quality, should be by extensive exploitation and utilization.
But existing boiler owing to can't guarantee the stable ignition state of biogas, can not effectively use this energy of biogas, let it fully burn, and then can cause the waste of biogas energy.
Summary of the invention
To the problems referred to above, the invention provides methane boiler, the stable ignition state that it can guarantee biogas makes biogas fully burn, not waste.
Methane boiler; Its technical scheme is such: it comprises steelframe, burner hearth, upper drum, lower drum, and said burner hearth is installed on the said steelframe, in the horizontal flue of said burner hearth top high temperature superheater, low temperature superheater is installed; Connect through convection bank between said upper drum, the lower drum; Economizer, air preheater are installed in the back-end ductwork, it is characterized in that: horizontal arrangement has biogas burner on the front wall of said burner hearth, and said biogas burner comprises biogas pipe, biogas import, methane outlet, guide vane; Said biogas import exposes to said burner hearth and is communicated with said biogas pipe; Said methane outlet is the through hole that is distributed in biogas pipe periphery, and said guide vane is welded in the periphery of said biogas pipe, and said guide vane is arranged in the biogas flow direction of said through hole.
It is further characterized in that: the both ends lid of said biogas pipe is equipped with dome.
After adopting structure of the present invention, biogas is in fast state when through hole flows out, and under the guide functions of guide vane, mixes with the inner flue gas of burner hearth; Because the flue gas in the burner hearth is in high temperature; Biogas is heated when mixing, and has formed biogas, the smoke mixture after the heating, owing to mixed air in the flue gas; The stable ignition state that it has guaranteed biogas makes biogas fully burn, not waste.
