Technical field
The utility model relates to coal burner field, especially relates to a kind of micro-oil coal powder burner.
Background technology
Adopt the heat power plant boiler of traditional sparking mode, it opens, stops the larger by oil consumption of process and low-load combustion-stabilizing process, thereby has risen the multiple fuel-saving technique taking tiny-oil ignition technology as representative, has obtained large-scale application.The installing space of the front and back arch of W stove, highly at full stretch, brings great inconvenience to the installation of hard pipe type oil gun and burning torch, maintenance.Meanwhile, due to the version of burner and the difference of mounting arrangements, existing W stove tiny-oil ignition technology, mainly for the W stove that adopts bispin air duct burner, can not directly apply to and adopt on the two W stoves of adjusting wind whirlwind coal burner of the low NOx of concentrated type.At present, the two each start and stop of W stove of adjusting wind whirlwind coal burner (EI-XCL moulded coal powder burner) of the low NOx of concentrated type can only adopt large oil gun to carry out, and oil consumption is very large.
Utility model content
The purpose of this utility model is to provide a kind of micro-oil coal powder burner, solve existing difficult problems that adopted the W stove of the two tune of the low NOx of concentrated type wind whirlwind coal burner cannot apply fuel-economizing firing technique, and this problem that type of furnace coal burner region installing space is little, Maintenance and Repair are inconvenient.
The utility model solves the technical scheme that its technical problem adopts: a kind of micro-oil coal powder burner, comprise the main injection jet that is arranged on one end, be arranged on the pulverized coal channel that the other end is connected with elbow, be arranged on the combustion barrel between main injection jet and pulverized coal channel, inner cavity chamber and ring-like outer chamber in the middle of described pulverized coal channel and combustion barrel are provided with and are positioned at; Described pulverized coal channel comprises separable upper pipeline and lower pipeline, and described lower pipeline and combustion barrel are one-body molded, and the inner chamber of described upper pipeline is connected with blast pipe, and described lower pipeline tilts and is provided with oil gun mouth, and oil gun stretches in the inner chamber of combustion barrel from oil gun mouth.
For the oil gun that is easy for installation and removal, described oil gun comprises burning torch head and the oil transportation conduit of end, and described oil transportation conduit is flexible pipe.
In order to prevent burner wall scaling loss and coking, burning torch head and the combustion barrel of described oil gun coaxially arrange.
In order to detect wall surface temperature, on described main injection jet, be provided with thermocouple.
Further, in described main injection jet, be provided with combustion chamber, combustion chamber is connected with combustion barrel, and combustion chamber is also provided with inner chamber and exocoel, and the intracavity diameter of described combustion chamber is greater than the intracavity diameter of combustion barrel.
Further, be also provided with concentrated cone between described pulverized coal channel and combustion barrel, the diameter of combustion barrel is less than the diameter of pulverized coal channel.
Preferably, between described combustion chamber and combustion barrel, be provided with concentrated ring.
The beneficial effects of the utility model: described pulverized coal channel adopts Split type structure, when mounted, can be according to the lower pipeline of local space rotation, for oil gun mouth is selected correct position, convenient installation, is then connected upper pipeline with lower pipeline, thereby meet, oil gun is installed, the operating space of maintenance.The oil transportation conduit of described oil gun adopts hose construction, makes the rear end taking-up space requirement of oil gun very little, facilitates installation and maintenance.Described chamber structure enters in the inner chamber of combustion chamber a part of coal dust to light, then is lighted by combustion chamber exocoel and entered the coal dust in next stage chamber by the coal dust of lighting in combustion chamber, realizes the classification of coal dust and lights, and reaches the object of fuel-economizing.Burning torch head and the combustion barrel of described oil gun coaxially arrange, and avoid oil gun flame directly to wash away burner wall and cause scaling loss and coking, affect the service life of burner.Combustion barrel is extended by the concentrated cone of former burner, and the impact by it on breeze airflow is down to minimum.
Below with reference to drawings and Examples, the utility model is described in detail.
