Description
Affiliated field
The utility model relates to a kind of novel gas soot blower, blows the combustion gas soot blower of ash in particular for boiler heating surface.
Background technology
Its cleaning is kept in the dust stratification and the slagging scorification of removing on the heating surface, is a kind of means that guarantee the safe and economical boiler operation.In general, guarantee that the heating surface cleaning can make boiler efficiency improve 1～3%.Become ash deposition on boiler heating surface after the burning of not flammable mineral matter in the boiler combustion, and little by little thicken and become dust stratification layer or slagging scorification layer, blow off as untimely, then dust stratification and slagging scorification will be serious day by day.According to test, dust stratification coking layer thermal conductivity factor has only 1/400～1/1000 of metal pipe-wall.Therefore behind the fouling of heating surface, make heat transfer deterioration, exhaust gas temperature raises, and reduces boiler thermal output.Dust stratification stops up flue, and is light then increase the flow resistance of convection pass, increases power consumption, and reduction is exerted oneself, and can stop up the flue circulation area when serious, hinders the proper flow of flue gas, the reduction boiler output, even may be forced to the blowing out deashing.
Also without any the method that effectively prevents dust stratification, the only resource is to adopt the soot blower selective sootblowing at present.Present most boiler is equipped with steam soot-blower, also has part to be equipped with compressed air soot-blowing, hydraulic(-ash) sluicing, sonic soot blowing equipment.But the common drawback of said method is to blow grey energy intensity to reach sphere of action inadequately limited, and some ash-blowing method such as steam soot blowing energy consumption height, and equipment dependability is poor, maintenance workload is big and heating surface is had infringement etc.Though boiler heating surface all has been equipped with above-mentioned soot blower mostly, service efficiency is low, and many places are in idle state.
It is to utilize flammable premixed gas body (be full of burning accelerating chamber after) to force to light the technology that the detonation shock wave carries out the top blast ashes that are heated such as boiler that produces that ash is blown in combustion gas, because it has and blow the big and dry type of grey energy and blow ash, in commercial Application more and more widely.The detonation that grey energy comes flammable premixed gas body in the spontaneous combustion accelerating chamber is blown in combustion gas, thereby to improve in the burning accelerating chamber flammable premixed gas physique amount flow be to guarantee that combustion gas blows the key point of grey effect.Present combustion gas is blown gray technology and is mainly used in boiler tail low temperature heating surface zone, it all is inflation in the burning accelerating chamber (opening is towards heating surface) of opening, resistance to flow output is very little, thereby the mass flowrate under same burning accelerating chamber volume is little, burning accelerating chamber capacity utilization is low, and in the burning accelerating chamber flammable premixed gas body mass flowrate and blow grey energy and can not regulate; In addition, be used for high-temperature heating top blast when ash, high-temperature flue gas can be lighted flammable premixed gas body in the burning accelerating chamber (below become " flash back ") when the flammable premixed gas body is not full of the burning accelerating chamber, be difficult to guarantee high-temperature heating top blast ash effect.
Summary of the invention
Deficiency for the combustion gas soot blower that overcomes present use, the utility model provides a kind of novel gas soot blower, grey energy is blown in adjusting thereby this device not only can increase flammable premixed gas physique amount flow rate under given burning accelerating chamber volume, and can be used for high-temperature heating top blast ash occasion.
The utility model is made up of combustible gas air inlet pipe, air intake duct, mixing chamber, ripple type spark arrester, igniting chamber, accelerating tube, burning accelerating chamber and spout etc., is linked in sequence by pipeline, and connected mode is flange or welding.It is characterized by igniting chamber and be provided with bull-plugged tee, the setting of burning accelerating chamber exit portion has the air hose of aperture, and spout is made of the pipe and the elbow of cutting sth. askew.The igniting chamber body is established the threeway that has plug, combustible gas is forced light the detonation shock wave that the back produces (effect be about after a few tens of milliseconds promptly can release) directly to impact plug, and directly do not impact inlet pipeline, promptly adopt the method for " instantaneous buffering " to solve the detonation tempering problem that ignition point occurs, improved the security performance of combustion gas soot blower.The air hose lee face of burning accelerating chamber outlet has aperture, the air that passes through from aperture can form air curtain and cover whole outlet cross section, can increase burning accelerating chamber resistance to flow output in the gas replenishment process on the one hand, improve the mass flowrate of flammable premixed gas body in the burning accelerating chamber, blow grey energy thereby increase; Flammable premixed gas body in high-temperature flue gas and the burning accelerating chamber can be separated on the other hand, avoid " flash back " effectively.Because the momentum of orifice jet (hole diameter is less) is far smaller than the momentum of detonation shock wave jet, thereby the air curtain that aperture forms is to blowing the almost not influence of grey performance impact.
The beneficial effects of the utility model be improve the combustion gas soot blower blow grey performance and security performance, and the range of application that combustion gas can be blown ash expands to high-temperature heating top blast ash occasion, on-the-spot mounting arrangements is convenient flexibly.
