Abstract
The invention provides a technical scheme of a gas-making furnace of a fixed bed. The technical scheme comprises a furnace wall formed by an upper fireproof wall and a lower water jacket; a coal-filling port is arranged at the top end of the furnace wall; a gas outlet is arranged at the upper end of the furnace wall; and an inner cavity encircled by the furnace wall is a furnace hearth. A plurality of parallel coal pushing plates which are closed in the way of surrounding the same cross section of the water jacket are fixed on the water jacket wall of the water jacket part in the furnace hearth; the width L of each coal pushing plate is 20-60mm; the inner ends of the coal pushing plates incline downwards; the included angle alpha of the coal pushing plates and the water jacket wall is between 30 and 60 degrees; and the topmost layer of the coal pushing plate is positioned at the connection end of the water jacket and the fireproof wall. With the adoption of the structure, as the inner ends of the coal pushing plates incline downwards, the contact between fire coal and the water jacket can be prevented to as to solve the problem of incomplete burning of fire coal caused by the cold wall, thereby achieving the purpose of reducing the carbon content of furnace ashes.
Description
Technical field:
What the present invention relates to is that a kind of coal chemical industry is used equipment, in particular for producing a kind of static bed gas making furnace of water-gas and semi-water gas.
Background technology:
The furnace wall of static bed gas making furnace all is that top is made up of water jacket refractory wall and bottom in the prior art, and adopting water jacket is slagging scorification on the furnace wall when preventing coal combustion as the purpose of furnace wall, and waste heat capable of using.Though water jacket can solve the problem of furnace wall slagging scorification, produced the problem of cold wall, cause the carbon content of ashes to increase.Authorize disclosed No. 200620086124.7 patents by Patent Office of State Intellectual Property Office, be the problem that the carbon content that solves ashes increases, this patent shortens height with water jacket; Make water jacket be in ash bed, do not contact the carbon content that can reduce ashes effectively, though adopted anticlogging structure in the furnace wall on water jacket top with fire coal; But still do not reach the purpose of not slagging scorification; Therefore, reduce the carbon content of slag, just keep away unavoidable slagging scorification problem in burner hearth; Avoid slagging scorification in burner hearth, just subtract the carbon content in the bound slag, this is the existing in prior technology weak point.
Summary of the invention:
The object of the invention is exactly not enough to existing in prior technology; And a kind of technical scheme of static bed gas making furnace is provided; This scheme is employed on the burner hearth inner water jacket wall fixedly coal-pushing plate; Coal-pushing plate does not contact fire coal with water jacket, avoided cold wall to cause the incomplete problem of fired coal combustion, reaches the purpose that reduces the ashes carbon content.
This programme is realized through following technical measures: static bed gas making furnace; Include the furnace wall that is made up of top refractory wall and bottom water jacket, on the top of furnace wall coal filling hole is arranged, there is the air outlet upper end of furnace wall; The inner chamber that the furnace wall surrounds is a burner hearth; The characteristics of this programme are on the water wall of said burner hearth inner water sleeve part, to be fixed with a plurality of coal-pushing plates that are parallel to each other and center on the same xsect closure of water wall, the width 1=20-60 millimeter of each coal-pushing plate, and described each coal-pushing plate the inner is all downward-sloping; Angle a=30-60 degree between coal-pushing plate and the water wall, the position of the superiors' coal-pushing plate is at the coupling end of water jacket and refractory wall.The concrete characteristics of this programme also have the distance L between described each coal-pushing plate=50-100 millimeter.The width of described coal-pushing plate is the 1=30 millimeter.Angle a=45 degree between described coal-pushing plate and the water wall.Distance L=70 between described each coal-pushing plate millimeter.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Because in this scheme; On the water wall of burner hearth inner water sleeve part, be fixed with a plurality of coal-pushing plates that are parallel to each other and center on the same xsect closure of water wall; Described each coal-pushing plate the inner is all downward-sloping, and the position of the superiors' coal-pushing plate is at the coupling end of water jacket and refractory wall.This structure; Because a plurality of coal-pushing plates are arranged on the burner hearth inner water jacket wall; The inner of coal-pushing plate is all downward-sloping, and fire coal can be concentrated to the center of burner hearth in the process that falls, and contacts with water jacket so coal-pushing plate can prevent fire coal; This causes the incomplete problem of fired coal combustion with regard to having been avoided cold wall, reaches the purpose that reduces the ashes carbon content.On existing static bed gas making furnace, adopt this programme transformation, the slag of discharging is detected, the carbon content of its slag is than not being lower than more than 10% through the Gas-making Furnace boiler slag carbon content of transforming.This shows that the present invention had compared with prior art both avoided slagging scorification in burner hearth, and reduced the carbon content in the slag, so this programme has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure synoptic diagram of the specific embodiment of the invention.
Fig. 2 is the structure for amplifying synoptic diagram of A among Fig. 1.
Among the figure, 1 is water jacket, and 2 is refractory wall, and 3 is burner hearth, and 4 is coal filling hole, and 5 is coal-pushing plate, and 6 is the air outlet, and 7 is the furnace wall.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through an embodiment, and combine its accompanying drawing, this programme is set forth.
Can find out through accompanying drawing; The static bed gas making furnace of this programme has the furnace wall 7 that is made up of top refractory wall 2 and bottom water jacket 1; There is coal filling hole 4 on 7 top in the furnace wall; There is air outlet 6 upper end of furnace wall 7, and the inner chamber that furnace wall 7 surrounds is a burner hearth 3, and this programme is on water jacket 1 wall of said burner hearth 3 inner water sleeves 1 part, to be fixed with a plurality of coal-pushing plates 5 that are parallel to each other and center on the same xsect closure of water jacket 1 wall; The width 1=20-60 millimeter of each coal-pushing plate 5, it is the l=30 millimeter that this embodiment adopts the width of coal-pushing plate 5.Described each coal-pushing plate 5 the inner are all downward-sloping, the angle a=30-60 degree between coal-pushing plate 5 and water jacket 1 wall, and this embodiment adopts the angle a=45 degree between coal-pushing plate 5 and water jacket 1 wall.The position of the superiors' coal-pushing plate 5 is arranged on the coupling end of water jacket 1 and refractory wall 2.Distance L=50-100 millimeter between described each coal-pushing plate 5.This embodiment adopts distance L=70 millimeter between each coal-pushing plate 5.
