Description
Oppfinnelsen angår et apparat for fremstilling av en gassblanding inneholdende hydrogen og carbonmonoxyd, omfattende et reaks jonskammer for delvis forbrenning av hydrocarboner med oxygen eller med oxygenanriket luft, eventuelt med tilfor sel av vanndamp, The invention relates to an apparatus for the production of a gas mixture containing hydrogen and carbon monoxide, comprising a reaction ion chamber for the partial combustion of hydrocarbons with oxygen or with oxygen-enriched air, possibly with the supply of water vapour,
ved overatmosfærisk trykk, og en til reaksjonskammerets gassutlop koblet kjele for avvarme hvori er anordnet to eller flere spiral- at superatmospheric pressure, and a boiler connected to the reaction chamber's gas outlet for deheating in which two or more spiral
ror som hvert står i forbindelse med et rett ror for gjennomstrom- rudder which is each connected to a straight rudder for flow-
ning av de gasser som skal avkjoles. Et kjolemiddel kan stromme rundt spiralrorene, og kjelen for avvarme er forsynt med en ledning for innforing av et kjolemiddel. ning of the gases to be cooled. A dressing agent can flow around the spiral tubes, and the boiler for heating is provided with a line for introducing a dressing agent.
Ved delvis forbrenning av hydrocarboner i et reaksjonskammer dannes en gassblanding inneholdende hydrogen og carbonmonoxyd og dessuten sotD Sotmengden i gassblandingen kan være så hoy som 5 During the partial combustion of hydrocarbons in a reaction chamber, a gas mixture is formed containing hydrogen and carbon monoxide and also soot. The amount of soot in the gas mixture can be as high as 5
vekt$. Gassblandingen som har en hoy temperatur av f^ks. 1300-1^00°C når dén forlater reaksjonskammeret, og et trykk av 5-150 atmosfærer, avkjoles i kjelen for avvarme. Gassblandingen strommer således gjennom spiralrorene som omgis av et strommende kjolemiddel. Kjelen for avvarme er som regel konstruert, som en vertikal, sylindrisk beholder med et innvendig ror og er forsynt med en bunnplate som via rette ror står i forbindelse med spiralror for de varme gasser som skal avkjoles, idet begge typer ror .er anordnet i det ringformige rom dannet mellom den ytre vegg og det innvendige ror. Rorenes nedre ende står via de rette ror. i forbindelse med et tomrom i kjelen for avvarme under bunnplaten som står i forbindelse med reaksjonskammerets gassutlop. Kjolemidlet ledes gjennom et innvendig ror til de rette rors gassinnlbpsende, og det innvendige rors nedre ende er forsynt med et sproytemunnstykke slik at kjolemidlet som tilfores gjennom dette ror, kan sproytesmot den varme bunnplate for det ledes oppad inn i det ringformige rom. En slik kjele for av- weight$. The gas mixture which has a high temperature of e.g. 1300-1^00°C when it leaves the reaction chamber, and a pressure of 5-150 atmospheres, is cooled in the boiler for deheating. The gas mixture thus flows through the spiral tubes which are surrounded by a flowing dressing agent. The boiler for deheating is usually constructed as a vertical, cylindrical container with an internal rudder and is provided with a bottom plate which is connected via straight rudders to spiral rudders for the hot gases to be cooled, as both types of rudders are arranged in it annular spaces formed between the outer wall and the inner rudder. The lower end of the rudders stands via the straight rudders. in connection with an empty space in the boiler for cooling under the bottom plate which is in connection with the reaction chamber's gas outlet. The coating agent is led through an internal pipe to the gas inlet end of the straight pipes, and the lower end of the internal pipe is provided with a spray nozzle so that the coating agent supplied through this pipe can be sprayed against the hot bottom plate before it is directed upwards into the annular space. Such a boiler for de-
varme er kjent f.eks. fra britisk patentsøknad nr. 8515^2. heat is known e.g. from British Patent Application No. 8515^2.
Avkjolingen av bunnplaten og av spiralrorene i forbindelse med denne kjente kjele for avvarme er ikke tilfredsstillende og svikter hvis trykket av kjolemidlet som strommer gjennom det innvendige ror, synker på grunn av driftssvikt. The cooling of the bottom plate and of the spiral tubes in connection with this known boiler for deheating is not satisfactory and fails if the pressure of the coolant flowing through the internal tube drops due to operational failure.
Et spesielt problem som er forbundet med avkjoling av sotholdig gass med hoyt trykk, beror på at gassrorene i kjelen for avvarme må være spiralformet anordnet for å hindre at sot vil avsettes på rorenes innside, og på at spiralformet anordnede ror alltid har en viss urundhet.som gjor at de får en mindre mekanisk styrke ved hoy temperatur enn rette ror som kan fremstilles med en langt storre grad av nøyaktighet„ A particular problem associated with the cooling of soot-containing gas at high pressure is due to the fact that the gas tubes in the boiler for heating must be spirally arranged to prevent soot from being deposited on the inside of the tubes, and that spirally arranged tubes always have a certain out-of-roundness. which means that they have less mechanical strength at high temperatures than straight rudders, which can be produced with a far greater degree of accuracy"
Et rett ror anordnes derfor foran hvert spiralformet ror, og i en slik kjele for avvarme dannes vanndamp med hoyere trykk, og dette er okonomisk mer gunstig. A straight rudder is therefore arranged in front of each spiral-shaped rudder, and in such a boiler for heating, water vapor is formed at a higher pressure, and this is economically more favorable.
Selv om det rette ror sterkt befordrer muligheten for å oppnå vanndamp med et hoyere trykk, gjenstår det problem at koblingen av de rette ror til den nevnte bunnplate utgjor et svakt punkt. Although the straight rudder strongly promotes the possibility of obtaining water vapor at a higher pressure, the problem remains that the connection of the straight rudders to the mentioned bottom plate constitutes a weak point.
Det tas ved oppfinnelsen sikte på å lose dette problem. The invention aims to solve this problem.
Oppfinnelsen angår derfor et apparat for fremstilling av en gassblanding inneholdende hydrogen og carbonmonoxyd, omfattende et reaksjonskammer for delvis forbrenning av hydrocarboner med oxygen eller med oxygenanriket luft, eventuelt med tilfor sel av vanndamp, ved overatmosfærisk trykk, og en til reaksjonskammerets gassutlop koblet kjele for avvarme hvori er anordnet to eller flere spiralror som hvert står i forbindelse med et rett ror for gjennomstrømning av de gasser som skal avkjoles og som kan være omgitt av et strommende kjolemiddel, idet kjelen for avvarme er forsynt med en kjolemiddelledning, og apparatet er særpreget ved at kjolemiddelledningen omfatter to konsentriske ror som munner ut i ét sproytemunnstykke som omfatter en sentral ejektor og minst en hjelpeejektor anordnet på siden av den sentrale ejektor og som er anordnet på en slik måte at kjolemidlet når frem til de rette rors gassinnlopsende og er slik konstruert at kjolemiddel fra det innerste av de konsentriske•ror tjener som tilforselsmateriale til ejektorene mens kjolemiddel suges ut. fra det ytterste ror av ejektorene. The invention therefore relates to an apparatus for the production of a gas mixture containing hydrogen and carbon monoxide, comprising a reaction chamber for the partial combustion of hydrocarbons with oxygen or with oxygen-enriched air, optionally with the supply of water vapor, at superatmospheric pressure, and a boiler connected to the gas outlet of the reaction chamber for heating in which two or more spiral tubes are arranged, each connected to a straight tube for the flow of the gases to be cooled and which may be surrounded by a flowing coolant, the boiler for cooling is provided with a coolant line, and the apparatus is characterized by the fact that the dressing agent line comprises two concentric tubes which open into one spray nozzle which comprises a central ejector and at least one auxiliary ejector arranged on the side of the central ejector and which is arranged in such a way that the dressing agent reaches the gas inlet of the straight tubes and is constructed in such a way that dressing agent from the innermost of the concentric •rudder ie as feed material to the ejectors while the dressing agent is sucked out. from the outermost rudder of the ejectors.
Det rette ror som spiralrorene står i forbindelse med, har den ^nodvendige lengde til at det kan danne en forbindelse mellom den forste vinding av spiralrorene og bunnplaten, og de tjener da som tilkoblingsstykke. Rorlengdene kan imidlertid også velges lenger, fveks. dersom dette er onskelig av konstruksjonsmessige grunner som skyldes det tilgjengelige rom ved gassinnlopssiden til kjelen for avvarme, eller dersom det er onskelig å nedsette gassenes temperatur for de kommer inn i den forste vinding av spiralrorene, The straight rudder with which the spiral rudders are connected has the necessary length to form a connection between the first turn of the spiral rudders and the bottom plate, and they then serve as a connecting piece. However, the rudder lengths can also be chosen longer, e.g. if this is desirable for constructional reasons due to the available space on the gas inlet side of the boiler for cooling, or if it is desirable to lower the temperature of the gases before they enter the first turn of the spiral tubes,
Bruken av to konsentriske ror som munner ut i et sprbytemunnstykke, kjolemidlet som fortrinnsvis ledes inn i det innerste rbr under trykk, tilfbrsel til ejektorene som også suger vann ut av det ytterste rbr som f.eks. står i forbindelse med en beholder inneholdende kjolemiddel og anordnet over kjelen for avvarme, sikrer at det oppnåes noen avkjoling på grunn av det i det ytterste rbr tilstede-værende kjolemiddel selv dersom tilfbrselen av kjolemiddel til det innerste rbr brytes, hvorved oppnåes en kortere tid som kan anvendes for å ta de nbdvendige skritt for å rette på skaden. Anvendelsen.av et sprbytemunnstykke omfattende én sentral ejektor og minst en hjelpeejektor sikrer en tilfredsstillende avkjoling både av bunnplaten og av de rette rbr ved deres gassinnlbpsender. Dette er spesielt til-felle dersom antallet av hjelpeejektorer er det samme som antallet' - av rette rbr og disse ejektorer samarbeider med sprbytemunnstykke-armer som er anordnet symmetrisk og munner ut mellom de rette rbr.' Disse armer er fortrinnsvis buet på en slik måte at det utstrbmmehde kjolemiddel. får en bevegelsesretning med en horisontal hastighetskomponent. The use of two concentric pipes which open into a spray nozzle, the cooling agent which is preferably led into the innermost tube under pressure, supply to the ejectors which also suck water out of the outermost tube such as e.g. is in connection with a container containing cooling agent and arranged above the boiler for heating, ensures that some cooling is achieved due to the cooling agent present in the outermost tube even if the supply of cooling agent to the innermost tube is interrupted, whereby a shorter time is achieved which can be used to take the necessary steps to correct the damage. The use of a spray nozzle comprising one central ejector and at least one auxiliary ejector ensures satisfactory cooling of both the bottom plate and the straight tubes at their gas inlets. This is particularly the case if the number of auxiliary ejectors is the same as the number of straight rbr and these ejectors cooperate with sprbyte nozzle arms which are arranged symmetrically and open out between the straight rbr. These arms are preferably curved in such a way that the clothing material is stretched out. gets a direction of motion with a horizontal velocity component.
Tfolge en spesiell utfbrelsesform av apparatet har det rom i kjelen for avvarme hvori sprbytemunnstykket er anordnet, et fritt tverrsnittsareal■ved det punkt hvor munnstykket er koblet til de konsentriske rbr, av ikke over 30 % av det rom hvori spiralrorene er anordnet. Dette forer til en forbedret strbmning av kjolemiddel gjennom kjelen for avvarme. According to a special embodiment of the apparatus, the space in the boiler for heating in which the spray nozzle is arranged has a free cross-sectional area ■at the point where the nozzle is connected to the concentric tubes, of no more than 30% of the space in which the spiral tubes are arranged. This leads to an improved flow of dressing agent through the boiler for deheating.
Det ovenfor angitte frie tverrsnittsareal kan oppnåes ved å an-ordne skjermer som f.eks. i forbindelse med en kjele for avvarme som har fire rette rbr, kan være buede og anordnet symmetrisk langs rommets vegg idet den konkave side er vendt mot veggen. The above-mentioned free cross-sectional area can be achieved by arranging screens such as e.g. in connection with a boiler for heating which has four straight ribs, can be curved and arranged symmetrically along the wall of the room, with the concave side facing the wall.
Om bnskes kan temperaturen til de gasser'som'skal avkjoles, nedsettes ved å sprbyte inn'et kjolemiddel, f.eks. vann, i gassene efter at de har forlatt reaks jonskammer et'. Denne forkjbling av gassene kan utfores kontinuerlig eller periodevis, f.eks. dersom det oppstår vanskeligheter med'tilforsel av kjolemiddel til kjelen for If desired, the temperature of the gases to be cooled can be reduced by substituting a cooling agent, e.g. water, in the gases after they have left the reactor's ion chamber et'. This connection of the gases can be carried out continuously or periodically, e.g. if difficulties arise with'the supply of dressing agent to the boiler for
avvarme. warm up.
