Description

Burner
Technical field
The utility model relates to a kind of burner, and it comprises a central passage and at least one coaxial circular channel round central passage, is used for supplying with independent common reacting gas or gas and carries MEDIA FLOW.This burner is particularly suitable for being used in the partial combustion of the carbon-containing fuel (for example subdivided solids fuel (such as the fine coal of carrier gas carrier bands such as nitrogen and/or carbon dioxide) of gas carrier band) that uses oxygen-containing gas, for example is used for making forming gas, fuel gas or the reducing gas of pressurization.
Background technology
The partial combustion of solid carbon fuel is also referred to as gasification, obtains by fuel and oxygen reaction.This fuel mainly contains carbon and hydrogen as combustible component.Carbon-containing fuel in small, broken bits that gas carries and oxygen-containing gas enter in the reactor with the individual passage of higher velocity flow in burner.The flame that always burning in the reactor, wherein, the oxygen in fuel and the oxygen-containing gas reacts under the temperature more than 1300 ℃, forms carbon monoxide and hydrogen.
Term used herein " oxygen-containing gas " is wanted to refer to and is contained free oxygen, O 2Gas, and comprise air, oxygen-enriched air (being the above oxygen of 21mol%), also have pure basically oxygen (being the above oxygen of about 95mol%), other comprise the gas that nitrogen and/or rare gas etc. are found usually in air.
Term used herein " solid carbon fuel " is intended to comprise that the various gas that are selected from the following material group carry combustible material and these mixtures of material, have in this material group: coal, coke with the coal manufacturing, the coal liquefaction residue, petroleum coke, soot, bio-fuel, and the microgranular solid that from oil shale, tar sand and pitch, obtains.Coal can be an any kind of, comprises brown coal, subbituminous coal, bituminous coal and anthracite.Solid carbon fuel is preferably worn into particle level size, and the material of feasible about at least 90% percentage by weight is less than 90 microns, and water content is less than about 5% percentage by weight.
US4,887,962 disclose a kind of burner at this partial combustion technology.This burner comprises that has a central passage and the coaxial circular channel that has outlet for the outlet of fuel to the combustion zone.The outlet of coaxial circular channel exports round central passage, and in order to oxygen-containing gas to be provided, oxygen-containing gas meets with the solid fuel stream that comes out from the outlet of central passage and mixes.This burner also comprises the preceding face that is positioned at the burner discharge end.Should have a centre bore by preceding face, fuel and oxygen-containing gas flow to the combustion zone through this centre bore.The approaching more outlet of diameter of the circular passage of supply oxygen-containing gas is more little, has formed an angle with respect to longitudinal axis.Because this narrow annular channel tilts along flow direction, effluent air stream will meet with the gas stream of the common reaction of flowing out from central passage and mix, and enters the combustion zone in downstream.
The temperature of carbon-containing fuel stream is generally 80 ℃, and the temperature of oxygen-containing gas stream is typically about 300～350 ℃.The temperature of combustion zone can be up to 1300 ℃ even higher.As a result, outer wall is exposed to different temperature and variations in temperature with inwall, causes different thermal expansions.Because the generally change between 1.5～2.5 meters of the longitudinal length of burner, the differences in expansion between the each several part can cause significant bending and bending stress load in relevant portion.
The utility model content
The purpose of this utility model provides a kind of burner configuration, can prevent because the mechanical stress that the thermal expansion of each several part causes.
The purpose of this utility model is by providing following a kind of burner to realize, at least a portion coaxial circular channel of this burner extends between the inside and outside wall of double-walled housing, the relative inner casing of one end of described double-walled housing is fixed, and its other end can slide on described inner casing.In this way, when inner casing with the double-walled housing different thermal expansions took place, they had freedom of motion vertically.
For example, by a plurality of grooves, for example the groove of three or more equidistant placement perhaps by being fixed on the circle on double-walled housing or the inner casing, can form described slidably joint.
Burner can be provided with coolant jacket.This point can realize round the double-walled housing of coaxial circular channel with the double-walled coolant jacket.The relative double-walled housing of one end of coolant jacket is fixed, and its other end can slide on the outer wall of double-walled housing, therefore, has formed along axial freedom of motion when coolant jacket and double-walled housing generation different heat expansion.The opening that the gas access can form on the upstream portion that the cover that is not cooled on the double-walled housing covers is connected to coaxial circular channel.
The end that interfixes of the double-walled housing of inner casing and encirclement for example can be soldered to a side of linkage unit, and this linkage unit is provided with the opening with corresponding passage alignment.In an opposite side of linkage unit, passage can continue and for example be limited by downstream part that is welded in the coaxial inner casing on the linkage unit and outer shell.Linkage unit also is used for fixing an end of the double-walled coolant jacket that slidably engages.Linkage unit can be provided with and be used for some openings of flowing through for cooling agent, and on the opposing face of linkage unit, coolant jacket can for example form with the hollow member that is fixed to described linkage unit simultaneously.Linkage unit can be for example near the discharge end setting, for example in about its external diameter 1-3 distance doubly, wherein, the upstream portion of coaxial circular channel, selectively also have the upstream portion of coolant jacket, form the double-walled housing that slidably engages, the one end is soldered to linkage unit.Term used herein " upstream " refers to gas flow direction in the burner.According to this configuration, upstream portion significantly is longer than the downstream part, therefore, can utilize the freedom of the axially-movable of double-walled housing best.Therefore more close combustion zone, downstream part is exposed to heat more, and these downstream parts replace with unitary part in the time of can or losing efficacy in the contingency variation.
The inwall that limits central passage can for example have constant diameter.Alternatively, inwall can be tapered on its partial-length.
Burner of the present utility model can be adapted to well by any hope mode (promptly vertically, flatly or angularly) reactant is introduced the reaction zone of partial oxidation gas generator, and be particularly suitable for being used for the equipment for gasification of solid fuels that the both sides relative substantially in the combustion zone are provided with a plurality of reactant burners, thus, reactant is flatly introduced, and burner jet clashes into mutually, promotes partial oxidation process, and makes the erosion minimum to the combustion zone wall.
Described burner can have a preceding face, and it is arranged in discharge end and perpendicular to longitudinal axis, preceding face has a centre bore, and gas flows to the combustion zone through this centre bore.Because ignition temperature can reach 1300 ℃ even higher, so the main consideration of this burner is to prevent that the high heat-flux in the gasification from causing the damage burner front face.For face before protecting was not subjected to pyrolytic damage, can on the outside of preceding face, apply refractory lining.By replaceable mode, perhaps replenish, can use the hollow wall member, have inner cooling path, for example spiral passageway.Fluid coolant circulates fast through this cooling path, to guarantee the even cooling of burner front face.
Burner is used the exotic material manufacturing usually, especially for example with trade mark Inconel
