Description
Technical field
The present invention relates to a kind of igniter for " W " flame boiler.
Background technology
" W " flame boiler coal burner is all be arranged on the forward and backward arch of burner hearth, and burner structure special (such as adopting cross-tube burner etc.).The main burner of " W " flame boiler is comparatively special, for cross-tube burner or miniature circular nozzle, if do not carry out characteristic changing to main burner, this main burner cannot be transform as plasma or Tiny-oil ignition device and reach the object of saving great amount of fuel oil.But because the burning of " W " flame boiler is original very fragile, once change main burner characteristic, boiler combustion will become more fragile, therefore usually can not transform the main burner of " W " flame boiler coal burner.Therefore the igniter of boiler main burner being carried out to routine adaptations cannot be adopted.
In addition, even if achieve energy-saving effect by the device transforming main burner, because limiting by the structure of boiler main burner, energy-saving effect is also very little.
Summary of the invention
The object of this invention is to provide a kind of igniter for " W " flame boiler, to solve the problem that difficulty is large, oil-saving effect is poor of " W " flame boiler transformation.
By the igniter for " W " flame boiler of the present invention, it comprises start-up burner and igniting accessory system, described start-up burner is designed to the coal burner set up separately independent of " W " flame boiler coal burner, the described coal burner set up separately is arranged under the forward and backward wall of " W " flame boiler in tertiary air, and/or is arranged in the upper overfire air port position of " W " flame pot arch; Described igniting accessory system is disposed in the described coal burner set up separately, and the coal burner set up separately for this provides incendiary source, in order to light the coal dust in this igniter.
Preferably, described igniter also comprises coal dust bifurcated pipe system, this coal dust bifurcated pipe system to be connected on " W " flame boiler pulverized coal channel and to have the branch of leading to the described coal burner set up separately, for distributing the coal dust needed for the described coal burner set up separately from " W " flame boiler pulverized coal channel.
Preferably, described igniting accessory system is few-oil ignition accessory system or plasma ignition accessory system.
Pressing in energy-saving ignition device of the present invention, by adopting coal dust bifurcated pipe system, the coal burner coal dust of boiler original main burner shunted, to cause under the forward and backward wall of boiler in tertiary air and/or arrange separately in the upper overfire air port position of " W " flame pot arch, light a fire, the difficult point cannot carrying out reducing energy consumption because of W flame boiler particularity can be solved.
In igniter of the present invention, by choose reasonable, it is installed in the position on boiler, and for the burner set up, the wind speed, air quantity etc. in this burner can be adjusted as required, and need not these parameters of main burner be adjusted, be applicable to dissimilar " W " flame boiler to enable igniter of the present invention.
It is utilize large oil gun to light a fire that " W " flame boiler starts originally, very large by oil mass, and by the igniter set up separately of the present invention, can realize replace oil with coal is also do not need great amount of fuel oil in start-up course, and only need coal dust burning, realize energy-saving ignition, after boiler improvement, boiler startup oil can be saved in a large number.
In addition, for the coal burner set up separately, not by the impact of boiler original main burner structure, can design it according to igniting is optimum, lighting of the coal dust that is highly advantageous to, substantially increases oil-saving effect.Adopt this to be used for the energy-saving ignition device of " W " flame boiler, W flame furnace igniting needs can well be suitable for, improve the efficiency of combustion of coal dust, improve oil-saving effect.
Accompanying drawing explanation
Be described in detail according to embodiments of the invention below in conjunction with accompanying drawing, to provide other features and advantages of the present invention.In accompanying drawing:
Fig. 1 is the structural representation of one of the present invention for the igniter of " W " flame boiler.
Detailed description of the invention
By the concrete structure of one embodiment of the invention see Fig. 1.
Energy-saving ignition device for " W " flame boiler comprises start-up burner 1, coal dust bifurcated pipe system 2, igniting accessory system 3 (such as few-oil ignition accessory system or plasma ignition accessory system), wherein, start-up burner is designed to the coal burner 2 set up separately, but not transform former boiler coal-ash combustor 5, that is, this start-up burner 1 is the coal burner newly established independent of boiler original coal burner.This coal burner 1 set up separately to be arranged in before or after " W " flame boiler under wall in tertiary air.Coal dust bifurcated pipe system 2 is connected on " W " flame boiler raw coal powder pipeline 4 that (this raw coal powder pipeline is connected to former boiler coal-ash combustor 5, for it provides coal dust) and there is the branch of leading to the described coal burner set up separately, ensure that start-up burner 1 is lighted a fire the source of coal dust.The coal dust of the former burner of " W " flame boiler can be shunted by this coal dust bifurcated pipe system 2, introduce the coal burner set up separately.Igniting accessory system 3 is arranged on the coal burner set up separately, for this coal burner provides incendiary source, in order to light the coal dust in this igniter.Said structure feature ensures the energy saver application success being used for " W " flame boiler, improves oil-saving effect.
Certainly, according to another embodiment of the present invention, also can provide coal dust individually for the coal burner 2 set up separately, and not distribute required coal dust from " W " flame boiler raw coal powder pipeline.
In addition, according to another embodiment of the present invention, the described coal burner set up separately also can be arranged in the upper overfire air port position of " W " flame pot arch.
What use due to " W " flame boiler is colm, and for the embodiment of above-mentioned employing coal dust bifurcated pipe system, the coal burner set up separately adopts the coal burner can lighting colm.Such as, Chinese Patent Application No. is 200810006973.0 is entitled as " one is applicable to meager coal, anthracitic tiny oil ignition whirlwind coal burner ", with Chinese Patent Application No. be 200720178273.0 be entitled as the disclosed burner structure such as " a kind of few oil ignition pulverized coal burner being applicable to colm " patent, can here adopt.
