Kiinteiden polttoaineiden kuten puunjätteiden polttamiseen on käytetty laitteita, joissa nämä ilmaan sekoitettuna esilämmitetään varsinaisesta tulipesästä erillisessä pyrolyysikammioissa, joiden läpi ne virtaavat. virtauksen ohjaamiseksi on käytetty uria, ritilöitä, arinoita, metallisydämiä, kanavia ja vastaavia, sekä vir-tausmatkan pidentämiseksi mutkittelevaa virtausta. Virtausnopeus on täten pieni, johon usein tarkoituksellisesti pyritäänkin, koska lämmittämiseen jää täten lyhyessä kanavassa enemmän aikaa. Kuitenkin juuri suuri virtausnopeus edistäisi pyrolyysiä. Myöskään mainittavia ylipaineita ei pyrolyysikammioissa ole käytetty, vaikka tämäkin edistäisi pyrolyysiä. Tarvittava lämpö on saatu joko varta vasten kehittämällä tai siirtämällä palamis-lämpöä takaisin kammion tuloaukkoon, jotka kumpikin ovat peräti mutkikkaita tapoja.For the combustion of solid fuels, such as wood waste, equipment has been used in which these, when mixed with air, are preheated from the actual furnace in separate pyrolysis chambers through which they flow. grooves, gratings, gratings, metal cores, channels and the like have been used to control the flow, and a meandering flow has been used to extend the flow distance. The flow rate is thus low, which is often deliberately aimed at, as there is thus more time for heating in the short duct. However, it is precisely the high flow rate that would promote pyrolysis. Also, no significant overpressures have been used in the pyrolysis chambers, although this would also promote pyrolysis. The required heat is obtained either by specifically developing or transferring the heat of combustion back to the inlet of the chamber, both of which are as complicated as possible.
67755 peräti mutkikkaita tapoja.67755 as many as complicated ways.
Oheisessa keksinnössä pyrolyysitila on sijoitettu turpiinin polttokammion kaltaisen varsinaisen palotilan sisään. Se on muotoiltu siten, että voidaan käyttää korkeaa painetta, joka lisää ilmassa olevan hapen tunkeutumista polttoaineeseen ja parantaa palamista, sekä suurta virtausnopeutta pyrolyyttitilassa, jotka molemmat mahdollistavat polttoaineen suuren ulossyöttönopeuden tulipesään, joka edelleen parantaa palamista itse tu-lipesässä. Koska pyrolyysitila on sijoitettu varsinaisen tulipesän sisään, ei mitään lämmitysprobleemeja ole. Keksinnön sisältönä on puruturpiinin polttokammio, johon kiinteä polttoaine kuten puru tai pienirakeinen turve johdetaan paineilman mukana siten, että polttoaine ja paineilma esilämmitetään ja kuumennetaan ollen se lähinnä tunnettu siitä että polttoaine ja ilma jonka mukana se kulkee kuumennetaan ja kaasuuntuu palotilan sisä-seinämiä kiertävässä paineenalaisessa putkikierukassa. Palotilan loppuosaan johdetaan tarvittava lisäilma tavanomaiseen tapaan täydellisen palamisen aikaansaamiseksi ja kaasujen lämpötilöan laskemiseksi.In the present invention, the pyrolysis space is located inside an actual combustion space similar to a turbine combustion chamber. It is designed to use high pressure, which increases the penetration of oxygen in the air into the fuel and improves combustion, as well as a high flow rate in the pyrolytic space, both of which allow a high fuel discharge rate to the furnace, which further improves combustion in the furnace itself. Because the pyrolysis space is located inside the actual furnace, there are no heating problems. The invention relates to a combustion chamber for a chewing turbine, into which a solid fuel such as sawdust or fine-grained peat is introduced with compressed air so that the fuel and compressed air are preheated and heated, mainly characterized by heating and gasifying The necessary additional air is introduced to the rest of the combustion chamber in the usual way to achieve complete combustion and to lower the temperature of the gases.
Oheisessa kuvassa on esitetty halkileikkauksena poltto-kammio. Tämä muodostuu ulkovaipasta 1 ja sisävaipasta 2 joiden välisessä tilassa 3 ja 4 esilämmitetään polttoil-ma 5 ja lisäilma 6 ilmavirtojen samalla jäähdyttäessä vaippoja.The following figure shows a cross-section of the combustion chamber. This consists of an outer jacket 1 and an inner jacket 2, between the spaces 3 and 4 of which the combustion air 5 and the additional air 6 are preheated while the air currents cool the jackets.
Poltettava aine puru, turve tai muu vastaava kiinteä aine johdetaan kammioon putkessa 7 paineilman avulla ja mukana siten että putki 7 kulkee ensin liekkien suuntaisesti 12, jolloin tapahtuu ilman ja polttoaineen esiläm-mitys ja tämän jälkeen putki kiertyy takaisin polttoti-lan sisäseinämiä kiertäen vaipan 2 vieressä. Tässä kie-rukkaosassa 8 polttoaine paineenalaisena kaasuuntuu ja purkautuu lopulta suurella nopeudella palotilaan 9 kierukan päästä 10 jolloin siihen samalla johdetaan lisäpa-lamisilma 5, jotta palaminen tapahtuisi.The combustible material debris, peat or other similar solid is introduced into the chamber in the pipe 7 by means of compressed air and entrained so that the pipe 7 first runs parallel to the flames 12, preheating the air and fuel and then recirculating the combustion chamber walls next to the jacket 2 . In this coil part 8, the fuel under pressure is gassed and finally discharged at a high speed into the combustion chamber 9 from the end 10 of the coil, whereby at the same time additional combustion air 5 is introduced in order for combustion to take place.
Palotilan loppuosaan 11 johdetaan vielä tarvittaessa lisäilmaa 6, jolloin palaminen saadaan mahdollisimmanIf necessary, additional air 6 is supplied to the rest of the combustion chamber 11, whereby combustion is possible as much as possible
