Abstract
The utility model discloses a mobile gasifying rotary burning boiler, including a boiler body, a fire grate, a rear arch and a cross wall of rear arch provided above the fire grate in furnace, a coal burning section formed among rear arch, cross wall of rear arch, fire grate and rear sidewall of boiler; a face arch provided on the front sidewall of boiler, a coal gasifying section formed among face arch, cross wall of face arch and fire grate, a flame channel declined to coal gasifying section provided between rear arch and cross wall of rear arch, the angle between flame channel and horizontal direction is 25-30 degree, a smoke outlet provided above the coal gasifying section, and a wind inlet provided for burning section and coal gasifying section. The high temperature flame airflow formed by coal burning section is guided into coal gasifying section of front part of boiler by flame channel, and rotated in the coal gasifying section because of the guide of flame channel and intensivemixing burned with the coal gas generated by coal gasifying section.
Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of mobile gasification rotary combustion boiler.
Background technology
The present boiler that has moved has mobile gasification boiler, also has all standing side outlet flue to move gasification furnace, the anterior steam gasification district (wet gasification) coal seam thick (about about 1 meter) of mobile gasification boiler, and easily coking is difficult for handling, and can not long-time continuous move; All standing side outlet flue moves gasification furnace, and the boiler body volume is big, steel consumption big, complex structure, the manufacturing cost height, and maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is will solve easy coking that above-mentioned mobile gasification boiler exists, be difficult for handling and steel consumption is big, complex structure, manufacturing cost height, the inconvenient problem of maintenance, and a kind of mobile gasification rotary combustion boiler that overcomes above-mentioned shortcoming is provided.
The utility model includes boiler body, fire grate, fire grate is moved behind stove by the stokehold, in burner hearth, carry the used coal of burning, before it is characterized in that, fire grate top in the burner hearth is provided with cross wall under rear arch and the rear arch, forms a coal combustion district under rear arch, the rear arch between cross wall, fire grate and the boiler rear wall; The front side wall of boiler has a face arch, form a coal gasification district under this face arch, the rear arch between cross wall and the fire grate, has a passage of flame that tiltedly has a down dip to the coal gasification district under rear arch and the rear arch between the cross wall, the angle of this passage of flame and horizontal direction is 25 °～30 °, the top in coal gasification district offers outlet flue, and this coal combustion district, coal gasification district have air inlet.
Coal gasification of the present utility model district is identical with the coal seam thickness of combustion zone, the thermal-flame air communication that the coal combustion district forms is crossed the coal gasification district that the passage of flame with guide effect enters the boiler front portion, and rotate in the coal gasification district because of the guiding of passage of flame, the heating boiler with the abundant mixed combustion of coal gas of coal gasification district generation, the flue gas that the burning back produces enters convection heating surface from the outlet flue of top, coal gasification district, because the air-flow in the coal gasification district is rotation status, burns away so large coal particles grain wherein can be fallen on the fire grate.
The utility model moves gasification furnace with existing mobile gasification boiler and all standing side outlet flue and compares, and has the following advantages:
1, simple in structure, it is little to adopt traditional boiler body to change, and steel consumption is little, and low cost of manufacture is easy to maintenance.
2, adopt high rear arch, coal is difficult for coking under the rear arch, and coal combustion is abundant; The thermal-flame air communication that the coal combustion district forms is crossed the coal gasification district that the passage of flame with guide effect enters the boiler front portion, and rotate in the coal gasification district because of the guide effect of passage of flame, the abundant mixed combustion of coal gas with the generation of coal gasification district, because the air-flow in the coal gasification district is rotation status, so large coal particles grain wherein can be fallen on the fire grate and burn away, the efficiency of combustion height, economize on coal, over-emitting black exhaust not.
3, conventional boiler rear arch temperature of lower is too high, the easy coking of coal, and coal combustion not exclusively and easily forms oxynitrides, and the face arch temperature of lower is low to be not easy to catch fire; Temperature-averaging under the arch before and after the utility model, coal easily catches fire and is difficult for coking, and it is few to form oxynitrides.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See also shown in Figure 1, the utility model includes boiler body 1, fire grate 6, fire grate 6 is moved behind stove by the stokehold, in burner hearth, carry the used coal of burning, it is characterized in that, fire grate 6 tops in the burner hearth 7 are provided with cross wall 4 under rear arch 5 and the rear arch, form a coal combustion district 9 under rear arch 5, the rear arch between cross wall 4, fire grate 6 and the boiler rear wall 8; The front side wall of boiler has a face arch 2, form a coal gasification district 10 under this face arch 2, the rear arch between cross wall 4 and the fire grate 6, has a passage of flame 11 that tiltedly has a down dip to the coal gasification district under rear arch 5 and the rear arch between the cross wall 4, this passage of flame 11 is 25 °～30 ° with the angle of horizontal direction, the top in coal gasification district 10 offers outlet flue 3, and this coal combustion district 9, coal gasification district 10 have air inlet.
Coal gasification of the present utility model district 10 is identical with the coal seam thickness in coal combustion district 9, the thermal-flame air communication that coal combustion district 9 forms is crossed the coal gasification district 10 that the passage of flame 11 with guide effect enters the boiler front portion, and because of the guide effect of passage of flame 11 10 rotations in the coal gasification district, the heating boiler with the abundant mixed combustion of coal gas of coal gasification district 10 generations, the flue gas that the burning back produces enters convection heating surface from the outlet flue 3 of 10 tops, coal gasification district, because the air-flow in the coal gasification district 10 is rotation status, burns away so large coal particles grain wherein can be fallen on the fire grate 6.Coal gasification district 10 is stuffy under normal condition, ventilates in it when some stove.
