Abstract
The utility model discloses a double-purpose coal powder burner with single or double channels, which is a new energy-saving burning device used for rotary kilns, comprising two concentric circles casing pipes, a central pipe is a channel supplied to air, and an air inlet channel is arranged between an outer sleeve pipe and the central pipe. A circular truncated cone shaped air damper is arranged at the end part of the central wind pipe, which can move axially by telescoping device. The supplemental air controls the ejecting amount by a valve and combines the air damper to adjust the flame profile; the utility model is a high efficiency energy-saving device. The utility model can be used as a coal powder burner with single passages provided with flame adjustment function under the condition of no supplemental air. The utility model has the advantage of simple structure; the double-purpose coal powder burner with single or double channels can directly be used in a coal powder combustion system of existing rotary kilns.
Description
The utility model belongs to the novel energy-conserving coal burner that a kind of rotary kiln is used.
The coal burner of existing rotary kiln, what use more than 98% is the single channel coal burner, in recent years introduce and developed the triple channel coal burner, but complex structure, processing difficulties, and need special steel material and pressure-air air-supply, whole coal burning system is comparatively complicated, thereby popularize and use difficulty bigger, especially existing coal burning system is transformed, difficulty is finished.
The purpose of this utility model is to invent a kind of burner of new structure, can overcome the single-pass coal burner to the ature of coal bad adaptability, and it is slow to heat up, and shortcomings such as incomplete combustion are more simple in structure, compact than triple channel coal burner again, is easy to make and promote.
Enforcement means of the present utility model are a kind of concentric circles thimble tube Double Pass Pulverized Coal Burners of design, central tube is for replenishing air duct, it between outer tube and central tube the breeze airflow passage, its exit is punctured into coal nozzle, the central air hose front end is equipped with air damper, central tube rear end socket joint is in a stationary pipes, and outer tube is drawn at the rear portion of stationary pipes, on the stage casing of central tube retractor device is housed.When the center airduct does not feed when replenishing air, promptly be the single channel coal burner of a band adjuster.
The advantage of the dual-purpose coal burner of this single binary channels is: simple and reasonable, easily manufactured, be applicable to the abundant burning of various coal dusts, flame profile is adjustable, quick heating is a kind of high efficiency energy-saving combustion apparatus, is particularly useful for the transformation of existing kiln burning system.
Accompanying drawing 1 is the basic structure schematic diagram (double as Figure of abstract) of single Double Pass Pulverized Coal Burners.
The drawing explanation:
The 1-outer tube, 2-central tube, 3-brace rod, 4-coal nozzle, 5-air damper, 6-retractor device, 7-stationary pipes, 8-gas control valve.
Embodiment 1:
Accompanying drawing 1 is a kind of structure of the utility model embodiment.It is that two concentric pipes are formed, central tube 2 is for replenishing air duct, it between internal and external casing the breeze airflow passage, outer tube 1 is punctured into coal nozzle 4 at air flow outlet, the front end of central tube 2 is equipped with air damper 5, the rear end socket joint is in stationary pipes 7, retractor device 6 is housed on the stage casing of central tube, can moves axially by its core barrel on and adjuster, retractor device can adopt the male and female screw thread of coupling or the gear and the tooth bar of coupling, gas control valve 8 is equipped with at the rear portion of stationary pipes 7, control replenishes the amount of air, and when apoplexy is big, flame is elongated, when apoplexy is little, flame is short; Adjuster is to protracting, and flame is thick, inwardly contracts, and flame is thin; Not feeding apoplexy, promptly is the single channel coal burner of a band adjuster.
Embodiment 2:
Accompanying drawing 2 is the improved form to coal nozzle 4 among the embodiment 1, in the front inner wall of coal nozzle 4 wind wing 9 is housed.
Embodiment 3:
Accompanying drawing 3,4,5 is can improved some forms to air damper 5 among the embodiment 1.Accompanying drawing 3 has a diameter enlarged portion part 10 for the front end of central tube 2 in air damper 5.Accompanying drawing 4 is equipped with wind wing 11 for the inwall of the front end of central tube in air damper 5.Accompanying drawing 5 is equipped with wind wing 12 for the outer wall of air damper.
