Description

The energy-conservation stove of steam added combustion
Technical field
The utility model relates to the stove and accessory field, relates in particular to a kind of steam added combustion stove.
Background technology
At present, along with the shortage day by day of global resources, increasingly high to the cry that improves the non-renewable resources utilization rate.Coal is as big, the heavy-polluted a kind of typical fuel of consumption, and improving its utilization rate, reducing toxic emission is a urgent problem.The shortcoming of existing Fuel Furnace is that energy utilization rate is not high, and fuel combustion is insufficient, takes away a large amount of heats, coke and carbon monoxide in the cigarette, and coke as toxic gas, especially to atmosphere has bigger pollution to environment as solid particle, carbon monoxide.In the prior art, in order to improve the utilization rate of coal, it is the method for carbon monoxide and hydrogen mixture that people utilize steam in high temperature, to combine to generate water-gas with carbon; Invented the method that in stove and accessory, adds steam combustion supporting, but in this method, steam adds too many; Can not guarantee stove and accessory high temperature; And owing to add continuously, steam is isolated coal that burns in the stove and oxygen, causes stove fire to extinguish on the contrary.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of steam combustion-supporting that utilizes is provided, make fuel combustion fully, improve energy utilization rate, reduce the steam added combustion stove of environmental pollution.
The purpose of the utility model and solve its technical problem underlying and adopt following technical scheme to realize:
The steam added combustion stove of the utility model; Comprise smokejack, grate, ash bin, combustion chamber, burner hearth, base, be provided with combustion chamber in this burner hearth, burner hearth and combustion chamber are positioned on the base; Ash bin is positioned at base; Grate be located at the base inner stove core under, smokejack is positioned at the burner hearth upper end and is communicated with burner hearth, wherein: it is bocca that said combustion chamber upper end is provided with like dry hole; This bocca top is provided with the water bag, and water is wrapped through the burner hearth outer circumference surface and is provided with water inlet pipe, and water is wrapped end and is provided with main escape pipe; Between combustion chamber and burner hearth, be provided with at least one air channel near the inboard wall of burner hearth place; The air channel upper end is communicated with bocca; The air channel lower end extends to burner hearth bottom, is provided with at least one escape pipe of connecting with main escape pipe in the ash bin of burner hearth below, and the gas outlet of escape pipe is positioned at the air channel lower end.
Above-mentioned steam added combustion stove, wherein: said air channel is three, is evenly distributed in the burner hearth, three air channel lower ends are provided with three corresponding with it escape pipes of connecting with main escape pipe.
Above-mentioned steam added combustion stove, wherein: said upper furnace outer circumference surface is provided with charging aperture and is communicated with combustion chamber.
Above-mentioned steam added combustion stove, wherein: said burner hearth top is provided with stone or metal plate for standing a stove on as a precaution against fire.
Above-mentioned steam added combustion stove, wherein: said stone or metal plate for standing a stove on as a precaution against fire is provided with chimney base and is communicated with smokejack.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know that by above technical scheme be provided with bocca in the burner hearth of combustion chamber upper end, the combustion chamber at this bocca place is provided with like dry hole; Above bocca, be provided with the water bag, water is wrapped through the burner hearth outer circumference surface and is provided with outlet pipe, and water is wrapped end and is provided with main escape pipe; Between combustion chamber and burner hearth, be provided with three air channels near the inboard wall of burner hearth place, the air channel upper end is communicated with bocca, below burner hearth, is provided with three escape pipes of connecting with main escape pipe in the ash bin, and the gas outlet of escape pipe is positioned at the air channel lower end.When the combustion chamber fuel combustion,, make the water boiling in the water bag produce water vapour through bocca; Water vapour is entered into each escape pipe of bottom of furnace body through main steam outlet tube by the water bag; Enter into bocca through three air channels again, under high temperature action, the carbon monoxide that water vapour and bocca discharge carries out redox reaction; Produce hydrogen and carbon dioxide, thereby reach combustion-supporting purpose; Water vapour does not directly get into burner hearth, and fire box temperature is reduced too much, can not completely cut off contacting of coal and oxygen yet, makes in the furnace chamber burnt fuel remain on relative stationary temperature simultaneously and burns, thereby reach purpose of energy saving; Simultaneously, water vapour makes coal ash particle density become big, and coal smoke carries Dust Capacity and significantly reduces, and reaction sharply descends the carbon monoxide content in the coal smoke, and hydrogen can not pollute, and can effectively reduce the coal smoke exhaust emission.
