Description

Combustion shaped coal boiler

It is the combustion shaping coal burning boiler of fuel with the shaped coal that the utility model relates to a kind of, can be widely used in especially being applied in the miniature boiler in the Industrial Boiler.

Existing Industrial Boiler generally is the diffusing coal burning boiler of combustion, is main fuel with the coal that looses, and it is many that this Industrial Boiler exists the consumption coal, efficient is low, and energy loss is big, pollutes and heavily waits shortcoming, and these shortcomings have injured the human existence space, have aggravated shortage of energy, have hindered the development of boiler industry.

The purpose of this utility model is to provide a kind of compact conformation, it is simple to make, cost is low, energy-conservation, efficient is high, fundamentally solved the combustion shaped coal boiler of air pollution problems inherent.

In order to achieve the above object, the utility model combustion shaped coal boiler comprises lower house, be installed in the worm screw on the lower house, worm gear, main shaft by the vertical placement that worm gear drove, the lower support bearing that the main shaft lower end is installed is welded on the gusset that distributes radially main shaft is played the role of positioning on the lower house, has the upper shell of heat-insulating property, be positioned at the rotating disk that upper shell is installed in the main shaft upper end, be installed in several coal courages on the rotating disk, water inlet pipe is near the water tank of coal courage top installation, be installed in several heat absorption smoke exhaust pipes in the water tank, outlet pipe is installed in the chimney of upper shell top, is used to hold the supporting plate of shaped coal after coal courage furnace bottom is pulled out.

The utility model combustion shaped coal boiler, its operation principle is: by manual or motor-driven by worm gear---worm-drive, the motion of driving rotating disk, the coal courage is gone to fire door and removes the cinder notch place, use the coal tong tool earlier shaped coal is clamped, aim at and put into the coal courage, unclamp anchor clamps, pull out coal courage furnace bottom, allow cinder drop down onto on the following supporting plate, push back furnace bottom then.The initial period of shaped coal burning, available liquefied gas burner is placed on to light on the supporting plate and ignites, and shaped coal is heated to ignition temperature.The gas that produces during the shaped coal burning is discharged by chimney through the heat absorption smoke exhaust pipe in the water tank.Water enters water tank by water inlet pipe, is discharged by the outlet pipe outlet again, finishes circulation.

The utility model combustion shaped coal boiler, in order to strengthen combustion efficiency, furnace temperature can feed steam more than 800 ℃, is lower than 800 ℃ and stops to feed steam, a bubbling air.When steam rises,, take fire, played combustion-supporting effect through coal courage heat zone.In the combustion process, whole body of heater is except that the chimney exhaust, and being close to is the insulation appearance body of a sealing, and heat scatters and disappears few.Coal courage or shaped coal can make different shape as required, so that the shaped coal honeycomb hole aligns, thereby ventilation is smooth in combustion process, and burning is fierce, can grill thoroughly shaped coal.

The utility model combustion shaped coal boiler, during owing to the shaped coal burning, burning zone can have very big increasing, the furnace temperature height, it is well arranged to burn, and the utilization rate of coal reaches more than 99%, and the consumption coal is few, energy-conservation.The steam that feeds in coal courage bottom resolves into H in heat zone ₂, O ₂, H ₂Content is airborne 14 times, has increased heat after the burning, O ₂Played combustion-supporting effect, can improve the thermal efficiency more than 15%, thermal efficiency height than the diffusing coal of combustion.Again because shaped coal is cellular, and contain additive and through compressing, thereby be difficult for producing flue dust and CO, SO ₂Deng pernicious gas, shaped coal is fully burnt, carbon containing is few in the lime-ash.In addition, do not need the such frequent coal of astigmatism coal, the number of times that has significantly reduced coal and poked fire, excess air coefficient is also less, and this has just reduced flying upward of duff grain and dust, over-emitting black exhaust not substantially during burning.Therefore, under the situation of no smoke abatement device, smoke medicining dust-removing effect is very obvious, can reach more than 96%, and pernicious gas is also few.

The utility model combustion shaped coal boiler because compact conformation is made simply, does not need air blast and smoke abatement device again, thereby, low cost of manufacture.

The utility model combustion shaped coal boiler structure compactness is made simply, and cost is low, generally can economize on coal 20%～40%, energy-conservation, compare with the diffusing coal burning boiler of combustion, evenly heat efficient has improved more than 15%, has eliminated air pollution effectively, has fundamentally solved air pollution problems inherent.

Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.

Fig. 1 is the structural representation of the utility model combustion shaped coal boiler.

Fig. 2 is the A among Fig. 1---the A cutaway view.

At Fig. 1, among Fig. 2, the utility model combustion shaped coal boiler comprises that lower house (1) is installed in the worm screw (2) on the lower house (1), worm gear (3), the main shaft (4) of the vertical placement that is driven by worm gear (3), the lower support bearing (5) that install main shaft (4) lower end, be welded on the gusset (6) that distributes radially on the lower house (1) main shaft (4) is played the role of positioning, upper shell with heat-insulating property, be positioned at the rotating disk (7) that upper shell is installed in the main shaft upper end, distribute in order and be installed in square coal courage (8) on the rotating disk (7), water inlet pipe (9), near the water tank (10) that install on coal courage top, be installed in several heat absorption smoke exhaust pipes (11) in the water tank (10), outlet pipe (12), be installed in the chimney (13) on upper shell top, be used to hold the supporting plate (14) of shaped coal after coal courage furnace bottom is pulled out.

The combustion shaped coal boiler that the utility model proposed, said upper shell with heat-insulating property is by the inner casing made from refractory brick (15), and the insulation material of being dosed between metal shell (16) and inner casing (15) and the shell (16) (17) constitutes.

The combustion shaped coal boiler that the utility model proposed near coal courage (8) shaped coal import, is provided with the fire door (18) that is used to be placed into moulded coal, removes cinder notch (19) and supporting plate (14) in upper shell the place ahead.In addition, near rotating disk (7) bottom one steam inlet pipe (20) is set also, is used to lead to that into steam is combustion-supporting in lower house (1) one side.

The combustion shaped coal boiler that present embodiment proposed, said coal courage (8) is not limited to square, also can be made into other shape, as long as can conveniently dress up moulded coal and the interior levels shaped coal of coal courage (8) honeycomb hole aligns,

The combustion shaped coal boiler that present embodiment proposed is generally miniature boiler, and large-sized boiler can adopt chain drive to carry shaped coal.

Present embodiment is simple in structure, and is easy to manufacture, and cost is low, energy-conservation, and evenly heat efficient is up to 75%～80%, and the evenly heat efficient of the diffusing coal burning boiler of combustion only is 60%～65%, and smoke medicining dust-removing effect is very remarkable.
