In the figure: 1. a burner housing; 2. a rotary burner; 3. a burner port; 4. an airflow inlet; 5. a rotating shaft; 6. a rotating drum; 7. a combustion tank; 8. a parting strip; 9. an airflow aperture; 10. an ash storage area.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1 and 2, a furnace anti-coking rotary combustion system comprises a burner shell 1, a rotary burner 2 and a feeding device, wherein a combustion port 3 is formed in the top of the burner shell 1, the combustion port 3 is of a flaring structure with an inclined surface, so that fuel can conveniently enter the rotary burner 2, the feeding device feeds the fuel to the combustion port 3, and an airflow inlet 4 is formed in the bottom of the burner shell 1, wherein the feeding device has two feeding modes, one mode is that the horizontal combustion port 3 is used for feeding the fuel, the fuel slides onto the rotary burner 2 along the inclined surface, and a spiral feeder can be selected; the other is to dump the fuel downwards from the side of the flame in the combustion area, and the fuel falls into the combustion port 3.

Rotatory combustor 2 includes pivot 5, power unit, rotary drum 6 and combustion chamber 7, pivot 5 passes through the bearing and installs on the relative both sides wall of combustor shell 1, power unit is motor and gear train, and from the rotation of external drive pivot 5, the pivot drives rotary drum 6 again and rotates, combustion chamber 7 equipartition is on the outer peripheral face of rotary drum 6, and combustion chamber 7 separates the constitution at the parting bead 8 of rotary drum surface for the setting of a plurality of parallels and axial extension, the equipartition has air current hole 9 on rotary drum 6 and the parting bead 8, combustion chamber 7 on rotary drum 6 upper portion forms the combustion area with the cooperation of burner port 3.

The lower part of the combustor shell 1 is internally provided with an ash storage area 10, a slag removing door is arranged at the ash storage area 10, and the height of the airflow inlet 4 is higher than that of the ash storage area 10 and lower than the bottom of the combustor.

The working principle is as follows:

the feeding device sends biomass particles, semi-coke or other combustible particles to a combustion groove 7 on the rotary combustor 2 below the combustion port 3, and part of air used for combustion is from air originally flowing at the combustion port 3, and part of air enters the combustor shell 1 from the airflow inlet 4 and upwards enters the combustion port 3 through airflow holes 9 on the rotary drum 6 and the partition strip 8, and is fully mixed with fuel and then is combusted.

When the burning, motor drive pivot 5 slowly rotates, pivot 5 drives rotary drum 6 and rotates, and then drives the slow process burner port of combustion tank 7, the speed of control rotational speed and burning matches, when guaranteeing that combustion tank 7 rotates the burner port, fuel has fully burnt, becomes the lime-ash, along with the rotation of rotatory combustor 2, the lime-ash falls into lime-ash storage area 10 under the action of gravity and stores up, the staff only need regularly clear up the lime-ash storage area can.

Because the lime-ash drops from rotary combustor 2 in time, can not excessively pile up, form the coking, just discharged before the coking for rotary combustor 2 can keep lasting clean state, even if there is slight residue to remain, can not influence rotary combustor 2's continuous use yet.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
