Abstract
The utility model discloses an ultra-micro oil ignition device of a micro hearth, which comprises a powder feeding pipe, a coal guiding pipe, a fuel oil guiding gun, a micro hearth burner, high-temperature mixed burner and a regulating baffle board, wherein the regulating baffle board gets partial fire coal from the primary powder feeding pipe, and coal gets into the micro hearth burner through the coal guiding pipe, and the coal gets into the high-temperature mixed burner to burn a large of coal power in a main pipe after the coal is fired by the fuel oil guiding gun, air quantity of combustion-supporting air is cooled through a matching gas film, and coal power achieves secondary intensified firing in the hearth. The utility model has the advantages of excellent flame steady combustion effect, high burning efficiency and quite ideal effect through testing. The polluted material discharge amount such as CO, NO x, dust and the like is low, the inner wall of the hearth does not slag.
Description
Technical field
The utility model relates to the coal-burning boiler technical field, in particular to be a kind of little burner hearth ultra micro oil drop fire device.
Background technology
The igniting of coal burning boiler of power station and steady combustion all can consume great amount of fuel oil every year.In recent years, along with rising steadily of crude oil price, the power station fuel oil more and more is restricted, and coal-burning boiler igniting and stable combustion oil also are used as an important performance assessment criteria.Though some product contrasts with original point ignition technique in the past, and very big breakthrough is arranged in energy-conservation, safety, environmental protection.But need a large amount of fuel oils.Because present fuel oil anxiety, price is high again, thus we conscientiously understand with labor after, adopt little burner hearth firing technique as ignition of the boiler, the epoch-making substitute products of stable combustion oil.
The utility model content
The purpose of this utility model is the weak point at above-mentioned prior art existence, and a kind of new little burner hearth ultra micro oil ignition system is provided, and the technical scheme that the utility model adopted is:
A kind of little burner hearth ultra micro oil drop fire device, it comprises: once give tube cell, draw the coal pipe, the oil gun that ignites, little hearth combustor and high temperature mixing burner, it is characterized in that: it also comprises controllable register, described controllable register intercepts partial fuel coal from once giving the tube cell, enter little hearth combustor by drawing the coal pipe, ignited after oil gun lights, entered ignite a large amount of coal dusts in the main line of high temperature mixing burner.Described high temperature mixing burner place also is provided with air film cooling combustion air, by controllable register, changes the coal-supplying amount of pilot flame, and proportioning air film cooling combustion air amount makes coal dust realize the secondary overheavy firing in burner hearth.
The utility model compared with prior art adopts little burner hearth ultra micro oil drop fire device beneficial effect to be: effective through the steady combustion of test flame, and the efficiency of combustion height, effect is quite desirable.And pollutant discharge amounts such as CO, NOx, dust are low, not slagging scorification of inboard wall of burner hearth.
Description of drawings
Fig. 1 is the structural principle schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In order to summarize the purpose of this utility model, some aspect of the present utility model, advantage and novel feature have been described here.Should be appreciated that, need not all these aspects, advantage and feature and be included among arbitrary special embodiment.
Little burner hearth ultra micro oil ignition system of the invention intercepts partial fuel coal by controllable register 3 from once giving the tube cell 1, by drawing coal pipe 2, enters little hearth combustor 5, after the oil gun 4 that ignited is lighted, can stop oil firing.Allow coal dust rotary combustion in the little burner hearth coal burner of deep or light eddy flow, the rotation purpose is to allow coal dust stroke distances in little hearth combustor strengthen, and prolongs the time of coal dust in little hearth combustor, to reach the purpose of completing combustion.This system only needs little burner hearth point fuel oil of trace, and the heat that coal dust self burns is kept the temperature in little burner hearth, and spontaneous combustion became pilot flame after the coal dust of back entered little burner hearth, enters a large amount of coal dusts in the main line that ignites behind the high temperature mixing burner 6.Product adopts brand-new structure, by controllable register 3, changes the coal-supplying amount of pilot flame, cooperates the air channel of optimal design to arrange, and proportioning air film cooling combustion air 7 air quantity, makes coal dust realize the secondary overheavy firing in burner hearth.
Though the present invention with preferred embodiment openly as above; but they are not to be used for limiting the present invention; anyly be familiar with this skill person; without departing from the spirit and scope of the invention; from when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection domain of protection scope of the present invention.
Claims (2)
1, a kind of little burner hearth ultra micro oil drop fire device, it comprises: once give tube cell, draw the coal pipe, the oil gun that ignites, little hearth combustor and high temperature mixing burner, it is characterized in that: it also comprises controllable register, described controllable register is installed in once to be given in the tube cell, the described coal Guan Yuwei hearth combustor that draws communicates, and the described tube cell of once giving communicates with the high temperature mixing burner.
2, little burner hearth ultra micro oil drop fire device according to claim 1, it is characterized in that: described high temperature mixing burner place also is provided with air film cooling combustion air.
