Background technology
China is large agricultural country, and agricultural crop straw output is about 700,000,000 ton/years, occupies first place in the world.At present, the main application of China's stalk is papermaking, feed, the life in the countryside energy (use acts as a fuel), and some is used for also Tian Zaofei, and remaining stalk goes out of use or burns, and becomes " use is little " but " discarded object " that must dispose.The annual summer harvest and when the autumn and winter; always there are the stalks such as a large amount of wheats, corn to burn in the field, produced a large amount of heavy smogs, not only become the bottleneck problem of rural environmental protection; even become the arch-criminal of bringing disaster to urban environment, become the new source of rural pollution.Along with expanding economy, primary energy supply growing tension has been subject to attention as the renewable biomass energy that stores and transports.Can to have kind many, complex-shaped owing to biomass energy, must could normally use on a large scale after treatment.The raw materials such as pin rice husk, wood chip can directly use on the ebullition, gasification combustor or on the fluidized-bed gasification furnace.For maize straw, branch etc., be through pulverizing, could normally use after making particle full-size less than 10mm.Living beings are pulverized make powder, make it as fuel that gasification, and combustion is a kind of very promising application mode under fluidised form, the applicant finished utility model patent " biomass boiling gasification combustion apparatus " patent No. 200720307169.7 in 2007.Comprise feeder, fan structure and gasification combustion chamber, be provided with the gas burner of discharging burning for high-temperature fuel gas in the middle and upper part of gasification combustion chamber's sidewall, the discharging opening of feeder is arranged on the position that gasification combustion chamber's sidewall is lower than gas burner and with gasification combustion chamber and communicates; The gasification combustion chamber bottom is provided with air-distribution device, and the fan structure provides general mood stream by air-distribution device one time to gasification combustion chamber, and the fan structure is communicated with the discharging opening of feeder by the feed airduct.It is indoor that this device is blown into gasification, and combustion with biomass fuel from the charging aperture of gasification combustion chamber, under the effect of a general mood stream that rises in bottom, autopneumatolysis combustion chamber, and the biomass fuel boiling; After lighting, biomass fuel carries out imperfect combustion and generates the high-temperature combustible gas body under fluidized state, and the high-temperature combustible gas body is discharged directly burning by gas burner.Engineering actual motion through 2 years, in service at whole equipment of discovery, gas burner is the weak link of whole equipment, particularly when making large-scale ebullition, gasification burner, often occurs that combustion process is wayward, burner is by problems such as ash obstructions.
Summary of the invention
For overcoming the wayward difficult problem of the combustion process that exists in the prior art, the object of the present invention is to provide the easily combustor special for biomass fluidized-bed gasification combustion machine of control of a kind of combustion process.
For achieving the above object, the technical scheme taked of the present invention is as follows:
A kind of combustor special for biomass fluidized-bed gasification combustion machine, its special feature is: comprise air inlet pipe and relatively it can move axially and the air inlet sleeve pipe of radial rotating (but air inlet sleeve pipe radial rotating and moving axially, the length that air inlet pipe is inserted when moving axially can change, air inlet pipe maintains static), reflection cone and blast tube, the external diameter of air inlet pipe is identical with the internal diameter of air inlet sleeve pipe, air inlet pipe one end is installed with the flange visor, the distolateral wall of this air inlet pipe is provided with air inlet simultaneously, the air inlet pipe other end inserts the air inlet inside pipe casing, described blast tube is comprised of straight length and Taper Pipe section two parts that (straight length is gas supply pipe, can determine its length according to on-the-spot installation requirement, the Taper Pipe section is burning zone), it is inner that air inlet sleeve pipe one end inserts straight length, is installed with reflection cone in the blast tube of straight length and Taper Pipe section junction.
Further, for solving burner by grey blockage problem, the air inlet cannula tip of straight length inside is installed with dust remover, and the dust remover external diameter is identical with inside diameter of straight pipe section, and the air inlet sleeve pipe other end sets firmly runner.
Further again, described dust remover comprises at least two swivel beckets, connect by scraper plate in the circumferential direction of the circle between the swivel becket, and dust remover is by in the junction of swivel becket and scraper plate, is installed in the air inlet cannula tip by rib.
Preferably, described swivel becket is two, and scraper plate is four and evenly distributes along the swivel becket circumferencial direction, and rib is four.
Preferably, coaxial setting between air inlet pipe, air inlet sleeve pipe, straight length, Taper Pipe section, the reflection cone.
Better, reflection cone is installed in blast tube inside by rib.
Preferably, the rib of fixation reflex cone is preferably three.
Preferably, the cone angle of Taper Pipe section is preferably 30 ° ~ 45 °.
Burner of the present invention can use at the ebullition, gasification combustor, can be applicable to high temperature and the high ash content of its combustion gas, the burning of the high ash content combustion gas that the biomass material that particularly is applicable to powdery, fine granularity produces at ebullition, gasification stove, fluidized-bed gasification furnace.Beneficial effect performance of the present invention is as follows:
1, in air inlet pipe air inlet sleeve pipe and flange visor (peephole) are installed, can see the combustion case of burner by the flange visor, the combustion process of burner is carried out Real Time Observation, can in time adjust according to the characteristic of flame.
2, the air inlet sleeve pipe can carry out preheating to the air that enters burner.At the air inlet sleeve pipe runner and dust remover are installed, the external diameter of air inlet pipe is identical with the internal diameter of air inlet sleeve pipe, but air inlet sleeve pipe radial rotating also can move axially, can clear up the dust that adheres on the burner wall during rotating wheel, move axially the air inlet sleeve pipe and can clear up all and be attached to dust on the burner wall.Move axially simultaneously the air inlet sleeve pipe and also can change distance between air inlet sleeve pipe and reflection cone, when ebullition, gasification combustor load increases, will increase simultaneously the required air capacity of burning, at this moment increase the distance between air inlet sleeve pipe and reflection cone; When load reduced, at this moment also corresponding reducing of the required air capacity of burning will reduce the distance between air inlet sleeve pipe and the reflection cone; Therefore, air velocity is in optimum state in the time of can guaranteeing air and combustion gas mixing.
3, Air of the present invention is supplied by the middle part by the air inlet sleeve pipe, and air passes in ebullition, gasification burner inside, can finish the preheating of tertiary air.
4, at the air outlet slit place reflection cone is installed, air is umbrella shape under the effect of reflection cone opens, so that fully mix with combustion gas.
5, the present invention according in the combustion gas because content of ashes is large, temperature is high easily sticks on the wall, designed and do not shut down the device that can clear up.
