Abstract

The cold combustion gasifier is for pit-coal, bio-mass and rubbish with low and high combustion values, involving low investment and operational costs, since there is no use of sulphur or produced steam in the process. In the gasifier occurs a superficial combustion of coal, bio-mass and/or rubbish with high combustion values, whereby the partial oxidation of fuel components takes place against the natural tendency of gases to rise. The counterposed combustion (downwards) eliminates the pyrolysis phenomenon, generates no waste products, such as tar, oils, fluids. The resulting ash residue is dry and free from fuel constituents. The gasifier is a vertical double-walled construction, similar to a blast furnace. The inner wall is manufactured from a heat and corrosion resistant alloy, provided with a quantity of perforations (7), which provide passage to air and flue gas (1) from the space formed between the outer and inner wall in the gasifier chamber. The cross-section of the gasifier can be four-sided, rectangular or cylindrical. The coal and/or bio-mass are introduced into the gasifier via the upper edge until the lowest volume is filled to the level of the inflaming burners (12). The fuel burns on the base of this vertical chamber and the gases coming from it (smoke, water vapor, carburetted hydrogen molecules, carbon monoxide, carbon tetrahydride, hydrogen, etc.), are drawn into a pipe (8), partly as the result of the rising heat column and partly through the fan (10) which provides air to the reactor. This gasifier can be called a cold combustion gasifier, since the gas temperature is maintained at a low level.

Description

Kolen, biomassa en afvalstoffen koude verbrandingsvergasserCoals, biomass and waste cold combustion gasifier

Deze vinding heeft betrekking op het vergassen van alle soorten steenkool, biomassa’s en afvalstoffen met lage en hoge verbrandingswaarden tegen lage investerings- en 10 operationele kosten aangezien het geen zuurstof of geproduceerde stoom gebruikt in het proces.This finding relates to the gasification of all types of coal, biomass and waste with low and high combustion values at low investment and operational costs since it does not use oxygen or produced steam in the process.

Al jaren lang wordt er gasvormige brandstof uit kolen geproduceerd middels diverse verschillende processen. De meeste moderne vergassers zijn van een high tech design en erg kostbaar in aanschaf, produktie en onderhoud. Meestal een schachttype waarin de 10 steenkool wordt opgestapeld, ontstoken en stoom en zuurstof ingeblazen. Het synthese gas wordt meestal behandeld, gewassen en soms ook de chemische samenstelling gemodificeerd om onder andere een hoger percentage CH4 en H2te verkrijgen welke een hogere verbrandingswaarde hebben en betere verbrandingskarakteristieken.Gaseous fuel has been produced from coal through various processes for many years. Most modern gasifiers are of a high tech design and very expensive to purchase, produce and maintain. Usually a shaft type in which the coal is piled up, ignited and steam and oxygen blown in. The synthesis gas is usually treated, washed and sometimes also the chemical composition modified to obtain, among other things, a higher percentage of CH4 and H2 which have a higher combustion value and better combustion characteristics.

Verbrandingskarakteristieken zijn erg belangrijk wanneer de brandertechnologie matig is 15 zoals in de afgelopen jaren.Burning characteristics are very important when the burner technology is moderate as in recent years.

In deze koude verbrandingsvergasser vindt een oppervlakte verbranding van kolen, biomassa’s en/of afvalstoffen met hoge verbrandingswaarden plaats, waarbij de gedeeltelijke oxidatie van brandstofelementen plaatsvindt tegen de natuurlijke neiging van gassen om op te stijgen. De “tegengestelde verbranding” (naar beneden) elimineert het pyrolyse 20 fenomeen, genereert geen slak (teer, oliën, vloeistoffen). Het resulterende as residu is droog en vrij van brandstofelementen.In this cold combustion gasifier, surface combustion of coal, biomass and / or waste materials with high combustion values takes place, whereby the partial oxidation of fuel elements takes place against the natural tendency of gases to rise. The "opposite combustion" (downwards) eliminates the pyrolysis phenomenon, does not generate slag (tar, oils, liquids). The resulting ash residue is dry and free from fuel elements.

Het in dit geval geproduceerde gas is niet gereinigd en zal slecht presteren (of helemaal niet) in een conventionele brander. Echter, deze gassamenstelling (waarin de meeste koolwaterstoffen en ook water (oververhitte lagedruk stoom) zit) zal volledig worden ontleed 25 en geoxideerd in de gasbrandstof reactor (see US patent 4.708.637 en EU patent 0300079B1). Bovendien kan deze reactor een groot aandeel water ontleden en later in de vuurstraal met een hoge kinetische energie weer samenvoegen.The gas produced in this case is not cleaned and will perform poorly (or not at all) in a conventional burner. However, this gas composition (which contains most of the hydrocarbons and also water (superheated low-pressure steam)) will be completely decomposed and oxidized in the gas fuel reactor (see US patent 4,708,637 and EU patent 0300079B1). Moreover, this reactor can decompose a large proportion of water and later reassemble it with a high kinetic energy in the fire jet.

The US patent 4.708.637 heeft al meer dan 15 jaar bewezen dat het de meeste brandstoffen kan verbranden met CE - 99.99% en vaak naast een CO = 0 waarde was ook 30 de ΝΟχ waarde laag.The US patent 4,708,637 has proven for more than 15 years that it can burn most fuels with CE - 99.99% and often in addition to a CO = 0 value 30 was also low.

De gasbrandstof reactor completeert deze uitvinding van een vergasser met lage aanschaf en proceskosten.The gas fuel reactor completes this invention of a gasifier with low purchase and process costs.

Er wordt aan een nieuwe vinding gewerkt door de uitvinders. Een universele gas verbrandingsreactor, speciaal ontworpen voor dit gas, geproduceerd door de koude 35 verbrandingsvergasser.A new invention is being worked on by the inventors. A universal gas combustion reactor, specially designed for this gas, produced by the cold combustion gasifier.

De vergasser is een vertikale dubbelwandige constructie, gelijk aan een schachtoven (voorzover het de geometrie betreft). De binnenwand is vervaardigd van een hitte en corrosie bestendige legering voorzien van een hoeveelheid perforaties (7) welke de lucht en het rookgas doorlaten, vanuit de ruimte gevormd tussen de buiten· en binnenwand, in de 5 vergasserkamer. De doorsnede van de vergasser kan vierkant, rechthoekig of cilindrisch zijn.The gasifier is a vertical double-walled construction, similar to a shaft furnace (as far as geometry is concerned). The inner wall is made of a heat and corrosion resistant alloy provided with a number of perforations (7) which allow the air and the flue gas, from the space formed between the outer and inner wall, into the gasifier chamber. The cross-section of the gasifier can be square, rectangular or cylindrical.

De kolen en/of biomassa worden via de bovenkant in de vergasser gebracht totdat het onderste volume is opgevuld tot aan het niveau van de ontstekingsbranders (12). De brandstof brandt op de bodem van deze vertikale kamer en de hieruit voortkomende gassen 25 (rook, waterdamp, koolwaterstof moleculen, CO, CH4, H2 etc) worden in een buis opgezogen, deels ten gevolge van de opstijgende warmtekolom en deels door de ventilator die de reactor van lucht voorziet.The coal and / or biomass are introduced through the top into the gasifier until the bottom volume is filled up to the level of the ignition burners (12). The fuel burns at the bottom of this vertical chamber and the resulting gases (smoke, water vapor, hydrocarbon molecules, CO, CH4, H2 etc) are sucked into a tube, partly as a result of the rising heat column and partly through the fan which air the reactor.

Het ontwikkelde gas is een verontreinigd gas aangezien het vrije koolstof en koolwaterstofmoleculen bevat. Een conventionele brander is niet geschikt om deze 15 gasvormige brandstof efficiënt en ecologisch verantwoord te verbranden. Deze vergasser is ontwikkeld op basis van de goede verbrandingseigenschappen van de gasbrandstof reactor (US patent 4.708.637 en EU patent 0300079B1) en andere vergelijkbaar ontwikkelde verbrandingsreactoren. Dit type verbrandingsreactoren kunnen iedere gasvormige brandstof ontleden en oxideren met een verbrandingsefficiency van 99,99%. Deze kraken de 20 moleculen en fragmenten waardoor alle atomen vrijkomen. De overgebleven as is inert en wordt continu door een roterende ontlader (13) aan de onderkant automatisch afgevoerd, gestuurd door programma data verkregen uit eerdere testen met de specifieke kolen of biomassa’s.The gas evolved is a contaminated gas since it contains free carbon and hydrocarbon molecules. A conventional burner is not suitable for burning this gaseous fuel efficiently and ecologically. This gasifier has been developed on the basis of the good combustion properties of the gas fuel reactor (US patent 4,708,637 and EU patent 0300079B1) and other similarly developed combustion reactors. This type of combustion reactors can decompose and oxidize any gaseous fuel with a combustion efficiency of 99.99%. These crack the 20 molecules and fragments, releasing all atoms. The remaining ash is inert and is continuously discharged automatically by a rotary unloader (13) at the bottom, controlled by program data obtained from previous tests with the specific coal or biomass.

De verbrandingslucht is gerecirculeerde rookgas (1) (schoorsteen niveau), hetgeen 25 minder zuurstof bevat. Minder zuurstof betekent ook een lage thermische NOx vorming. De opgewekte gasstroom passeert de verschillende zones om verbrandingslucht te verkrijgen en een afkoelend effekt.The combustion air is recirculated flue gas (1) (chimney level), which contains less oxygen. Less oxygen also means a low thermal NOx formation. The gas flow generated passes through the different zones to obtain combustion air and a cooling effect.

Deze vergasser kan ‘koude verbrandingsvergasser” worden genoemd, aangezien de afgezogen gastemperatuur laag wordt gehouden om zoals gezegd de thermisch NOx 30 vorming te verlagen en de binnenwanden ver onder de gebruikstemperatuur te houden.This gasifier can be called "cold combustion gasifier", since the extracted gas temperature is kept low in order to reduce the formation of thermal NOx and to keep the inner walls well below the use temperature.

Elke zone-inlaat is voorzien van een regelklep (2 t/m 5) aangestuurd door een geautomatiseerd besturingssysteem.Each zone inlet is provided with a control valve (2 to 5) controlled by an automated control system.

Om de gastemperatuur te verlagen en kritische temperaturen te voorkomen, wordt er water gesproeid via een water nozzle (6) tegengesteld aan de gasrichting, gesitueerd op het 35 hoogste punt binnen de gasafzuigbuis (8). De gasafzuigbuis wordt zodoende gekoeld en waterdamp wordt gevormd hetgeen samen met de andere gassen de vergasser verlaat.To lower the gas temperature and prevent critical temperatures, water is sprayed through a water nozzle (6) opposite to the gas direction, situated at the highest point within the gas extraction pipe (8). The gas extraction tube is thus cooled and water vapor is formed, which leaves the gasifier together with the other gases.

Deze waterdamp zal worden ontleed in de reactor (9) tgv de kinetische energie en de twee elementen zullen later weer reageren in de laatste fase van de verbranding binnenin de vuurstraal, (ontleding ontstaat door interne kinetische energie, niet door hoge temperatuur) De gasafzuigbuis is over de hoogte voorzien van verschillende openingen om het 5 ontwikkelde gas ook in de bovenste zones binnen te laten. Deze openingen zijn voorzien van driehoekige deflectie box (afscherming vallende kolen) om te waarborgen dat er alleen gas in de afzuigbuis komt.This water vapor will be decomposed in the reactor (9) due to the kinetic energy and the two elements will later react again in the final phase of the combustion within the fire jet, (decomposition is caused by internal kinetic energy, not by high temperature). The gas exhaust pipe is provided with different openings over the height to allow the developed gas to enter the upper zones as well. These openings are equipped with triangular deflection box (shielding falling coal) to ensure that only gas enters the exhaust pipe.

De kolen (vallend van de bovenkant van de vergasser) die op deze deflektie boxen vallen zullen naar de vergasser kamerwanden rollen en dus een vrije ruimte (onder de 10 deflectors) overlaten waar de gassen zich kunnen verzamelen en dan door de gasafzuigbuis worden getrokken.Een gedeelte van het ontwikkelde gas wordt gerecirculeerd door de verbrandingsventilator (10) en via een Coanda versneller (11). Deze recirculatie ondersteund de stromingsuniformiteit binnenin de vergasser en vergroot de vorming van CO, H2, CH4 en reduceert de overmaat 15 aan zuurstof.The coal (falling from the top of the gasifier) that falls on these deflation boxes will roll to the gasifier chamber walls and thus leave a free space (below the deflectors) where the gases can collect and then be pulled through the gas extraction pipe. part of the developed gas is recirculated through the combustion fan (10) and via a Coanda accelerator (11). This recirculation supports the flow uniformity within the gasifier and increases the formation of CO, H2, CH4 and reduces the excess of oxygen.
