UplinjanjeGasification

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum, je možnost ločevanja sinteznega plina in dimnih plinov zgorevanja v dveh ločenih podkomorah sistema termične obdelave goriva na poševni rešetki.A technical problem solved by the invention is the possibility of separating the synthesis gas and the combustion flue gases into two separate sub-chambers of the slant-type fuel treatment system.

Stanje tehnikeThe state of the art

Proces zgorevanja trdega goriva, zlasti biomase in odpadkov, se sestoji iz naslednjih faz in sicer: segrevanja, sušenja, pirolize, uplinjanja in popolnega zgorevanja. Gorivo se ob prihodu v komoro prične segrevati in sušiti, nato se prične postopek razkrajanja (piroliza), uplinjanja in zgorevanja.The process of combustion of solid fuels, in particular biomass and waste, consists of the following stages: heating, drying, pyrolysis, gasification and complete combustion. Upon entering the chamber, the fuel begins to heat and dry, then the process of decomposition (pyrolysis), gasification and combustion begins.

Pri procesu uplinjanja je zaželeno proizvesti sintezni plin s čim večjo oz. dovolj veliko energetsko vrednostjo, da se plin lahko koristno uporabi.In the gasification process, it is desirable to produce a synthesis gas with as much or as little as possible. a sufficiently high energy value so that the gas can be used efficiently.

Znane rešitve so zgrajene tako, da se gorivo uplinja in zgoreva v eni komori. V tej komori se sintezni plin zmeša z dimnimi plini zgorevanja, kar mu zmanjša energetsko vrednost. Druga varianta je ta, da se dimni plini vodijo v vertikalne uplinjevalne komore.Known solutions are built so that the fuel is gasified and burned in one chamber. In this chamber, the synthesis gas is mixed with the combustion flue gas, which reduces its energy value. Another option is that the flue gases are directed into the vertical gasification chambers.

Slabosti teh postopkov so:The disadvantages of these procedures are:

- ločena uplinjevalna komora- separate gasification chamber

- slabo mešanje goriva na fiksni rešetki- poor mixing of the fuel on the fixed grille

- slabše prilagajanje vrsti goriva- Poor adaptation to fuel type

- veliko nezgorelih delcev- many unburned particles

Opis nove rešitveDescription of the new solution

Naprava in postopek za uplinjanje trdega goriva, zlasti premoga rešuje zgoraj opisani tehnični problem z uporabo gibljive rešetke (1), ki je nameščena v komori. Pod rešetko se kontrolirano vpihuje zrak v eno ali več conah (2). Nad rešetko je zgorevalna komora s pregrado (11) deljena v dva ali več dela (3.1 in 3.2), izdelane iz ognjevarne obloge. Položaj pregrade (11) se spreminja glede na vrsto goriva. V ti dva dela komore se zrak vpihuje v eni ali več conah (4). Gorivo dodatno segrevamo in uplinjamo z vodenjem vročih dimnih plinov skozi gorivo, ali z vbrizgavanjem pare (5). Pri uplinjanju s tem v gorivo ne dovajamo kisika, tako da nastaja sintezni plin višje energetske vrednosti.The apparatus and process for gasification of solid fuels, especially coal, solves the technical problem described above by using a flexible grille (1) housed in the chamber. Below the grille, air is controlled in one or more zones (2). Above the grate, the combustion chamber with a barrier (11) is divided into two or more sections (3.1 and 3.2) made of a fireproof lining. The position of the bulkhead (11) varies according to the type of fuel. These two parts of the chamber are blown into one or more zones (4). The fuel is additionally heated and gasified by directing the hot flue gas through the fuel, or by injecting steam (5). In the process of gasification, oxygen is not supplied to the fuel, thus producing a higher energy synthesis gas.

Pri tem procesu imamo ločeno uplinjanje in zgorevanje na isti gibljivi rešetki. Rešetka je lahko izdelana tudi kaskadno (6). Tako dobimo dvo ali več stopenjsko rešetko, ločeno s kaskado, ki omogoča da se gorivo močneje premeša, kar omogoča hitrejši razkroj in popolnejše zgorevanje večjih kosov goriva.In this process we have separate gasification and combustion on the same moving grate. The grid can also be made cascading (6). This gives a two or more stage grille, separated by a cascade that allows the fuel to be mixed more vigorously, allowing faster decomposition and more complete combustion of larger pieces of fuel.

Odprtina za vstop goriva (7) je nameščena višje, kar omogoča večjo količino goriva v prvi delu komore (3.1) in s tem ustvarjanje večje količine sinteznega plina. Naprava je izdelana tako, da omogoča odvod sinteznega plina skozi izstop (8) in nadaljno uporabo le tega, ali mešanje z ostalimi dimnimi plini v dogorevalni komori (10). V dogorevalni komori se vpihuje zrak (kisik) (9), ki istočasno zavrtinči dimne pline in omogoča dobro mešanje za popolno zgorevanje.The fuel inlet port (7) is positioned higher, allowing a larger amount of fuel in the first part of the chamber (3.1), thus generating more synthesis gas. The apparatus is designed to allow the synthesis gas to be drawn out through the outlet (8) and further used, or mixed with other flue gases in the combustion chamber (10). Air (oxygen) (9) is blown into the combustion chamber, which at the same time swirls the flue gases and allows good mixing for complete combustion.

V vseh treh izvedbenih primerih je zgorevalna komora le ena in je razdeljena na del za uplinjanje oziroma proizvodnjo sinteznega plina (3.1) in na del za zgorevanje (3.2) s pregrado komore (11).In all three embodiments, the combustion chamber is only one and is divided into the gas or gas production section (3.1) and the combustion section (3.2) by the chamber partition (11).

V prvem izvedbenem primeru (slika 1) gorivo vstopa skozi odprtino za gorivo (7) in potuje po gibljivi rešetki (1) najprej skozi del komore za proizvodnjo sinteznega plina (3.1) ter nato skozi del komore za zgorevanje (3.2). V komoro vpihujemo zrak (2) pod gibljivo rešetko (1) in po potrebi vpihujemo še paro (5) ali zrak v dodatnih conah (4). Sintezni plin se dviga iz gibljive rešetke (1) skozi odprtino za izstop sinteznega plina (8), vroči dimni plini pa iz gibljive rešetke (1) skozi odprtino za izstop dimnih plinov (12).In the first embodiment (Figure 1), the fuel enters through the fuel port (7) and travels through the flexible grille (1) first through a portion of the synthesis gas chamber (3.1) and then through a portion of the combustion chamber (3.2). The air (2) is blown into the chamber under the movable grate (1), and if necessary, steam (5) or the air in additional zones (4) is also blown. The synthesis gas is lifted from the flexible grate (1) through the exhaust gas outlet opening (8) and the hot flue gas is withdrawn from the flexible grille (1) through the flue gas outlet (12).

V drugem izvedbenem primeru (slika 2) gorivo vstopa skozi odprtino za gorivo (7) in potuje po gibljivi rešetki (1) najprej skozi del komore za proizvodnjo sinteznega plina (3.1) ter nato skozi del komore za zgorevanje (3.2). V komoro vpihujemo zrak (2) pod gibljivo rešetko (1) in po potrebi vpihujemo še paro (5) ali zrak v dodatnih conah (4). Vroči dimni plini nato potujejo v nasprotni smeri gibljive rešetke (1) proti delu komore za proizvodnjo sinteznega plina (3.1). S tem postane uplinjanje bolj intenzivno. Mešanico sinteznega plina in izgorelih dimnih plinov nato vodimo skozi odprtino za izstop sinteznega plina v nadaljnjo obdelavo.In another embodiment (Figure 2), the fuel enters through the fuel port (7) and travels through the flexible grille (1) first through a portion of the synthesis gas production chamber (3.1) and then through a portion of the combustion chamber (3.2). The air (2) is blown into the chamber under the movable grate (1), and if necessary, steam (5) or the air in additional zones (4) is also blown. The hot flue gas then travels in the opposite direction of the moving grate (1) towards the part of the synthesis gas chamber (3.1). This makes the gasification more intense. The mixture of synthesis gas and combustion flue gas is then passed through an opening for the exit of the synthesis gas for further processing.

V tretjem izvedbenem primeru (slika 3) gorivo vstopa skozi odprtino za gorivo (7) in potuje po gibljivi rešetki (1) najprej skozi del komore za proizvodnjo sinteznega plina (3.1) ter nato skozi del komore za zgorevanje (3.2). V komoro vpihujemo zrak (2) pod gibljivo rešetko (1) in po potrebi vpihujemo še paro (5) ali zrak v dodatnih conah (4). Gibljiva rešetka (1) ima še dodatno kaskado (6), ki omogoča dodatno premešanje goriva za boljšo učinkovitost ter boljšo kontrolo obeh procesov, kaskad je lahko tudi več. Z « · uporabo loput nato reguliramo, katero vrsto procesa želimo. Ob odprti loputi za dimni plin (14) in odprti loputi odprtine za izstop sinteznega plina (8) dobimo prvi izvedbeni primer. Ob zaprti loputi za dimni plin (14) in odprti loputi odprtine za izstop sinteznega plina (8) dobimo drugi izvedbeni primer. Ob zaprti loputi za dimni plin (14) in zaprti loputi odprtine za izstop sinteznega plina (13) ter odprti loputi za vstop v dogorevalno komoro (15) dobimo drugi izvedbeni primer, ki pa je nadgrajen z dogorevalno komoro (10). V to dogorevalno komoro vpihujemo zrak ali kisik skozi odprtine (9) in tako zvišamo temperaturo dimnih plinov.In the third embodiment (Figure 3), the fuel enters through the fuel port (7) and travels through the flexible grille (1) first through a portion of the synthesis gas production chamber (3.1) and then through a portion of the combustion chamber (3.2). The air (2) is blown into the chamber under the movable grate (1), and if necessary, steam (5) or the air in additional zones (4) is also blown. The moving grille (1) has an additional cascade (6), which allows additional fuel mixing for better efficiency and better control of both processes, and there may be more cascades. By using the flaps, we then control which type of process we want. With the flue gas flap open (14) and the flue gas outlet flap (8) open, the first embodiment is obtained. With the flue gas flap closed (14) and the flue gas outlet flap (8) opened, a second embodiment is obtained. With the flue gas flap closed (14) and the flue gas outlet flap (13) closed and the flap chamber inlet (15) open, a second embodiment is obtained, which is further upgraded with the combustion chamber (10). Air or oxygen is blown into the combustion chamber through the openings (9) to increase the flue gas temperature.
