Abstract
The utility model belongs to the field of energy resource and environment-protection, in particular to a small-sized smokeless coal-burning device. The coal-burning device mainly comprises a coal bucket (1), a lower horizontal grate (7), and a burning chamber (9), and is characterized in that an upper slant grate (2), an upper air chamber (3), a manual operation pusher (4), a push bar (5), a manual operation rocker (6) and a lower air chamber (8) are added on the device. Paved on the upper slant grate by gravity, the coal in the coal bucket carries out parallel flow burning by the high temperature flame ignition of the burning chamber. The burning is completed by pushing the coke on the lower part of the slant grate over the horizontal grate by manual operation coke pushing mechanism. In the process of pushing, the coal in the coal bucket continue to be replenished on the upper slant grate. Because the process of coal burning is carried out with parallel flow burning in a moving bed, the utility model has the advantages of steady burning, no black smoke and high burning temperature. The burning capacity of a single coal-burning device is 100-500 kg/h, so the utility model is suitable to the modification of smoke abatement and energy saving of coal-burning grate.
Description
Technical field
The invention belongs to the energy environment protection field, particularly a kind of coal-burning installation.
Background technology
In the energy resource structure of China, coal in the highest flight.Therefore, in industrial furnace, extensively act as a fuel with coal.Traditional hand burns the coal method, though equipment is simple, and incomplete combustion, chimney over-emitting black exhaust, serious environment pollution.If change coal gasification combustion into, can the contaminated solution problem, but equipment complexity, investment are big, the very big situation of only suitable Coal-fired capacity.Use mechanical coal combustion process,, can solve the smoke abatement and dust control problem as traveling-grate stoker or reciprocal grate, but the cost of equipment height, the bigger situation of only suitable Coal-fired capacity.For the small-sized combustion chamber of a large amount of fuel consumptions below 500kg/h, how can smoke abatement and dust control, do not increase too many cost of equipment again, this is a major issue.
Summary of the invention
The present invention seeks to under the prerequisite that does not increase too many cost of equipment, solve small-sized hand coal fired equipment incomplete combustion, over-emitting black exhaust environmental pollution problem.
From combustion process, the burning in coal seam can be downstream combustion or counter flow combustion.Common hand adds coal combustion and belongs to counter flow combustion, and it is difficult to avoid over-emitting black exhaust.Burning on the traveling-grate stoker belongs to downstream combustion, and it can avoid producing in the combustion process black smoke effectively.But it is big to make chain fire-gate metal wastage, makes its cost height, and use the combustion chamber that is not suitable for low burnup.Basic principle of the present invention is to use the downstream combustion method to separate never over-emitting black exhaust problem, with a kind of simple man-operated mechanism the coal seam is moved simultaneously, realizes continuous burning.
A kind of small-sized smokeless coal-burning device, coal-burning installation mainly is made up of coal bunker 1, lower horizontal fire grate 7, combustion chamber 9, it is characterized in that this device has increased upper angled fire grate 2, ipper air chamber 3, manually cut somebody's hair 4, push rod 5, manually rocking bar 6, lower air chamber 8.The inclination angle 35-50 of upper angled fire grate °.Coal in the coal bunker is layered on the upper angled fire grate by gravity, and the surface, coal seam is by the hyperthermia radiation thermal ignition of combustion chamber 9, blasts air with ipper air chamber 3 below the coal seam to realize the downflow type burning.Utilize cutting somebody's hair of manual coke pushing mechanism 4 to shift the coke of dump grate bottom onto on the horizontal fire grate 7 burning.Cutting somebody's hair connects push rod 5, and with manual rocking bar 6 with push rod, the reciprocating motion forward or backward of cutting somebody's hair.In pushing course, the coal in the coal bunker continues to add on the upper angled fire grate by gravity.Simultaneously, the air that utilizes lower air chamber 8 to blast of the coke on horizontal fire grate burns cinder with it.Because coal-fired process is to carry out downstream combustion in moving bed, therefore, burning steadily, over-emitting black exhaust not, ignition temperature height.
Description of drawings
Fig. 1 is apparatus of the present invention structural representation
Coal bunker 1, upper angled fire grate 2, ipper air chamber 3, manually cut somebody's hair 4, push rod 5, manually rocking bar 6, lower horizontal fire grate 7, lower air chamber 8, combustion chamber 9.
The specific embodiment
Implement example of the present invention as shown in drawings.Coal-burning installation mainly is made up of four parts: coal bunker 1, upper angled fire grate 2, manually cut somebody's hair 4 and lower horizontal fire grate 7 form.Coal in the coal bunker is layered on the upper angled fire grate by gravity, and the surface, coal seam is by the hyperthermia radiation thermal ignition of combustion chamber 9, blasts air with ipper air chamber 3 below the coal seam to realize the downflow type burning.Utilize cutting somebody's hair of manual coke pushing mechanism 4 to shift the coke of dump grate bottom onto on the horizontal fire grate 7 burning.Cutting somebody's hair connects push rod 5, and with manual rocking bar 6 with push rod, the reciprocating motion forward or backward of cutting somebody's hair.In pushing course, the coal in the coal bunker continues to add on the upper angled fire grate by gravity.Simultaneously, the air that utilizes lower air chamber 8 to blast of the coke on horizontal fire grate burns cinder with it.
Embodiment 1
Fugitive constituent 15% in the coal, and coal seam thickness 100mm is moisture 6%, 35 ° at the inclination angle of upper angled fire grate, coke pushing stroke 50mm, blast pressure 500Pa.
Embodiment 2
Fugitive constituent 20% in the coal, and coal seam thickness 200mm is moisture 9%, 45 ° at the inclination angle of upper angled fire grate, coke pushing stroke 100mm, blast pressure 1500Pa.
Embodiment 3
Fugitive constituent 35% in the coal, and coal seam thickness 300mm is moisture 15%, 55 ° at the inclination angle of upper angled fire grate, coke pushing stroke 150mm, blast pressure 3000Pa.
Because the mobile of coal seam is by gravity, so the length of dump grate can not be oversize.This has just limited the burning capacity of this kind burner.Generally, the separate unit burning capacity is less than 500kg/h.
